Hi there,
I don't mind converting videos too much while we wait for proper drivers and flying pigs. But I'm no expert and I think we need a thread for proper encoding settings. I use Ripbot because I was tired of MeGui so I encoded a few x264 files at a 320x240 resolution and 1000kb bitrate. It's still stuterring. So my question is: What's the best overall bitrate (audio+video) the Tilt can bear?
I think I pretty much covered this in this thread.
Not many people will give it a chance, but those who ARE willing to re-encode found it spot on.
Just saw this :

WTH? It's either HTC's fault or Microsofts'/WinMo.Kinda sad that a 1Ghz SnapDragon can't do it compared to the underclocked Acer Liquid.
So what? 720p playback is ONLY useful if you don't have to convert the files or if you want to play them on a TV.
No phone is able to play 720p video without conversion. So the only advantage would be to be able to play HD video via TV out. But the HD2 does not have TV out, so 720p playback would be absolutely useless on the HD2.
On the Acer , like on any other phone, you STILL have to convert the files. It will only play .mp4 video in 720p.
If you play them on the phone, then it doesn't matter whether you convert them to 720p or 480p, the screen is only 800x480 pixels. You have to convert them anyways.
And yes, it's HTC's fault, because they don't fully use the Snapdragon chipset. It has nothing to do with Windows Mobile. But it doesn't matter anyways unless the phone has TV out.
Maybe in a not so far, far away future, it will make sense to have 1080p (or even higher, who knows) capable mobile devices - as soon as they are intended to deliver that high resolution content to a really, really large display.
Watching 480 lines of resolution on a 4.3" screen comes close to watching a 1080p BluRay movie on a 50" TV set, no?
As of today, I am just happy with what HD2 delivers... and for the home cinema experience, I do prefer the "big" screen anyway.

Or via TV out!
But as the HD2 does not have TV out, 720p playback would be useless.
(because you'd not be ably to use files from your PC without conversion anyways)
Who says you cant play them with out conversion? I have never converted one file to play on my phone. So yes it would be useful. It its capable of doing it, why the hell cant it, there is not argument here.
It can do it, so it should be able to, simple as that.

720p works only with hardware acceleration. Hardware acceleration works only for videos converted to the right file format.
No phone currently supports 720p playback without conversion because conversion is needed in order to use the hardware acceleration that the (Snapdragon) chipset provides.
It doesn't matter whether you own an Acer Liquid, an HTC Bravo or an HTC HD2, none of them will play your 720p .avi files from your PC. You have to convert them first.
Conclusion: 720p playback without TV out is useless. Period.
I'm pretty sure HTC left out the HD playback support because they wanted to save money on developing/purchasing the necessary software/drivers. And that is a wise decision for a device without TV out, because 720p playback is useless when you still have to convert the files and have no TV out.
Heu HD2 is able to play 720p
The only bad thing is the non support of AC3 in coreplayer

That is only the case because of the stupidity and narrow-mindedness of HTC and Qualcomm (and, to a degree, Microsoft). There is no technical reason why an application shouldn't be able to handle a much wider range of codecs and still take full advantage of hardware acceleration. But Qualcomm insists on charging too much for the intellectual property rights to run software that is optimised for its hardware; HTC is too mean-minded to pay Qualcomm's fees and too lazy to ship its own multi-format software player (compare with, say, Samsung, whose proprietary video player software is both hardware-accelerated and extremely flexible about formats); and Microsoft can't be arsed to make Pocket Media Player support a sufficient range of formats and codecs either.
One can even quite reasonably blame the authors of Coreplayer for not having yet launched a version capable of using NEON instructions for video acceleration (something that is in the public domain and not under Qualcomm's control). All in all it's a bloody waste.

I completely disagree. Plenty of video is only available in 720p format; even for stuff that is available in 720p and low-res versions, the low-res version is often so low-res that downscaling the HD version would look a lot better on a screen the size of the HD2. It would be enormously much more convenient if one could simply download and play the 720p version without having to spend hour after hour after hour on conversion, and use only one version of the fule on both the phone and a desktop PC. Obviously this is not something you personally would find useful, but that doesn't mean you have to be such a dog-in-the-manger about it: the attitude of "I don't want to do it, therefore no one needs to or should be allowed to" is really rather narrow-minded.
Shasarak,
you don't understand. You are making assumptions that are simply not true. Let me correct you:
That is only the case because of the stupidity and narrow-mindedness of HTC and Qualcomm (and, to a degree, Microsoft).

Wrong: It has NOTHING to do with Microsoft and HTC. Nothing. It is only because of the Qualcomm chipset, that only supports acceleration for certain video formats.
BUT this is not an 'issue' limited to Qualcomm! There is no phone chipset that supports hardware acceleration of different video formats!
There is no technical reason why an application shouldn't be able to handle a much wider range of codecs and still take full advantage of hardware acceleration.

I don't know about the reasons, but fact is that NO phone chipsets supports that acceleration. So there must be a reason.
Even IF Microsoft or HTC would develop/pay for the appropriate software, the phones would STILL not be able to play other file formats because the chipset simply doesn't support it.
And other chipsets (not from Qualcomm) don't support it either.
It would be enormously much more convenient if one could simply download and play the 720p version without having to spend hour after hour after hour on conversion,

Sure, it would be more convenient.
BUT as I explained several times: It doesn't matter whether the phone supports 720p playback or not, because conversion is always necessary due to limitations of the chipset, which only supports acceleration for certail formats (which applies not only to Qualcomm chipsets, but to every other chipset as well).
Obviously this is not something you personally would find useful, but that doesn't mean you have to be such a dog-in-the-manger about it: the attitude of "I don't want to do it, therefore no one needs to or should be allowed to" is really rather narrow-minded.

Thsi is not my attitude.
PLEASE READ PROPERLY BEFORE YOU ATTACK PEOPLE.
I explained to you in detail why 720p playback ability does NOT mean that conversion is not necessary. Thus, your argument of "not having to convert the videos" is misplaced. As you can read in the article above, the Acer Liquid ONLY plays 720p video that has been converted. And this is the case with any other phone as well, because of the reasons I explained above.
I dont know much about playback in 720p on the HD2 yet, but
Damien123_666 has done loads of camera tweaks (very good by the looks of it) and if you notice, he is working on recording in 720p
im working on 720p, micro-modes, bmp files and also increased video quality so keep looking for updates daily
Click to expand...
Click to collapse
So theres obviously the potential
Damiens thread is about recording 720p video, not playing it. Afaik Snapdragon has the potential of recording 720p video.
Here it's true, HTC is to blame for not enabling it.
But what I was talking about is 720p playback.
This is only possible with hardware acceleration.
Hardware acceleration is only possible for certain formats.
This means: Even if your phone supports 720p playback, you still have to convert the files.
Shasarak said that 720p would be a benefit because we would not have to convert the files.
But that's not true.
Even if HTC would develop/purchase the necessary software, we would STILL have to convert the videos.
(like on the Liquid, see the linked post)
That means: The argument of "not having to convert the videos" is not applicable here, because it doesn't matter whether the phone supports 720p or not, the files must ALWAYS be converted.
This means: The only advantage of 720p would be playing back HD videos on a TV.
But our HD2 does not have TV out.
This means: 720p playback capability would not be useful for us, as we would still have to convert the files and we don't have TV out.
I hope that was clear enough now.
@Shasarak
You CAN blame HTC/Microsoft for not enabling 720p playback, that's true.
BUT even IF they would enable it, they could ONLY enable it for certain file formats. You CAN NOT blame them for not enabling 720p for all formats, because this is a hardware limitation that exists on all other phones as well, no matter what manufacturer or OS.
I think you will find that people were blaming HTC for not enabling support. No one was complaining about it being available on only certain formats.
If my phone is capable of something, then I would like it to be able to do it. Simple as that.
No, you got it wrong, too.
People are not only blaming HTC for not enabling 720p playback, they are also blaming HTC/MS for not enabling it for all formats, and that's nonsense because that is not HTC's or MS's fault but a hardware limitation.
Just because the hardware is capable doesn't mean you can expect the support. It also needs software and that adds additional developing costs!
If HTC would have enabled it, they would have had additional costs, which means the phone would have been more expensive for you.
You can only expect what you pay for. You paid NOT for 720p video support, because that was not advertised anywhere by HTC.
HTC made the desicion not to enable it in order to be able to sell the phone at lower price. You either respect that desicion or buy another phone. You can not expect anything that nobody promised to you.
And as explained before, due to the fact that conversion is ALWAYS needed, 720p support is useless without TV out. You should be happy that you didn't have to pay for a useless feature.
seed_al
WTF are you talking about? Convertion is always needed? The CPU will downscale the video on the fly to fit the screen. You don't seem to know much (just like the Zunehd does). Any CPU is capable of.playing any format as long as the software enables it. You don't seem to understand this. SnapDragon just like nVidia's Tegra APX (& iPhone 3GS) is capable of decoding 720p WMV/MP4/H.264 at a bitrate up to 14bit/s 29fps. Even a feking Pentium2 can do this but at something like 0.02fps. The fact is that the software/drivers on WinMo aren't provided on the HD2
@MasterTP
Wrong. Completely.
You're mixing up hardware and software decoding! Do some research.
Of course any CPU can play anything. But only with software decoding, no hardware acceleration!
Hardware acceleration is only possible for certain formats. You even said that yourself: Snapdragon is cabable of decoding H.264/MP4 with the right software. But nothing else. Same for Tegra, iPhone and all the others!
That means even IF HTC had enabled 720p support, we would still have to convert the videos. Exactly what I said above. So please, next time, think before you post, instead of mixing everything up.
You guys are mixing everything up! I really don't know how to explain it any clearer.
I'll try one last time:
Okay, first of all: You have to distinguish between software and hardware decoding.
Every CPU can decode anything via software with the right codecs. That's what programs like Coreplayer do.
BUT: Software decoding is slow. Much too slow for 720p HD video.
THUS: 720p playback is only possible with hardware decoding.
Snapdragon, Tegra etc. support hardware decoding of 720p video.
BUT: Only for certain formats and only with the right software.
THUS: If HTC would provide the software, we could play 720p video like the Acer Liquid.
BUT: We would still have to convert the video files! (same for Acer Liquid, iPhone etc.)
THUS: The 720p playback capability would not free us from having to convert the videos!
THUS: The only advantage would be the ability to play 720p video on a TV.
BUT: Our HD2 does not have TV out.
THUS: 720p playback capability would not help us at all. We would still have to convert the videos and we would still have no TV out.
Okay, I think this is as clear as it gets. Got it now?
This thread made me lol
Personally I want my phone's battery to get hot enough for use as a hotplate.
There isn't a technical reason not to un-enable this non-feature, so HTC are stupid and m$ is evil.

No, I'm afraid you're the one who is mixing things up. It is indeed the situation at the moment is that only certain video player applications can make use of hardware acceleration on the HD2, and that those applications are only capable of playing a limited range of video formats. You make the mistake of assuming that, because this is the case, there must be something about those video formats which makes it inherently easy to play them with hardware acceleration, while it is inherently not possible to play any other format that way.
That is not true. There is no technical reason why someone cannot make a video player app which can play back any video and take advantage of hardware acceleration while doing it; the reason this hasn't happened is because of a combination of money-grubbing, selfishiness and incompetence on the part of Qualcomm, HTC, Microsoft, and a few other companies too.
If either Qualcomm were to release full details of their hardware, or HTC were prepared to spend a little more money, someone would then be able to write a video player app which could play back as many formats as Coreplayer and use full hardware acceleration while doing it. Whether that theoretical application could play back 720p video smoothly is another question; but I wouldn't be surprised. Assuming it could, such an application would require no conversion of 720p material to play it.

well it DOSE can play 720P with htc album. but for baseline profile and only 15fps……OK? 720P is here will you use it？
I don't know what seed_al was talking about.
I can play 720p video on my Touch HD (not HD2), but the performance is terrible.
If CPU is powerful enough, and software can utilize the GPU, playing back 720p (.avi) smoothly on a phone is possible for sure.

Exactly my point, there could be a thousand of different reasons. But maybe our devs inhere are a bit sharper than Samsung themselves...
People have made mods that claim an extra 20 - 30 megabytes of RAM. When these are applied problems are noticed with 720p recording. Imagine the ram usage for 1080p. I don't think its worth the hassle.
1080p used in mobile phones do you think will be much better?
come on!
i dont think so...
Especially since the audio is still bollixed... if they fixed that first.

Dont think it need it.
First if hardware permit to record 1080p stream the 5megapixels chip wont manage to provide 1080p frames with a decent framerate.
then if it could the optics wont be able to resolve the resolution gain.compared with n8 nokia or iphone 4 720p output you can see what there s place for improvement in this way(sharpest optic and better sensibility)
but may our dev can work on compression level to keep more fine detail , sensibility management or faster autofocus without resolution change.
think this is the only reasonable improvement we could expect by software mod
Well, I have problems with 1080p playing, let alone recording.
Anyway, the hardware is 100% capable of 1080p recording and it would be really cool if some can mod it.

Hummingbird is capable of 1080p hardware decoding/encoding. It's equipped with hardware encoders/decoders. Both of them require decent amount of RAM reserved. I think that was the issue.
5mpix sensor is perfectly capable of delivering decent framerate @720p, why wouldn't it be capable of 1080p?
Resolution is enough, there might be bandwidth limiting factors between sensor-CPU.
Optics is perfectly capable of making quite sharp photos @5mpix, why wouldn't it be capable of shooting just 1920x1080?
There will be no software mod enabling 1080p recording, without hacking into hardware codecs/drivers.
Even if the framerate would go down to 15-20 fps, I would personally really like this feature. Some moments are best captured in highest resolution possible. An idea about the memory could be to allocate needed amount on demand, thereafter releasing it again?
Thanks for confirming that our Galaxy S is indeed hardware-wise capable of recording in 1920x1080.
Actually, why 1080p? It doesn't NEED to be 1080p. Why can't we add support for 800p (800lines vertical res) or even 960p.
We keep thinking about making the jump to 1080p, but is there any reason why would couldn't ramp up the resolution higher on the camera? Just because your TV expects 720p, doesn't mean computers do when playing it back...

800p and 960p are not common, so it would make things awkward. Can't play it on a 720p screen and not properly on a 720p screen.
BTW although noticable I don't think the difference between 1080p and 720p is that big. So I don't think anyone would really notice the difference between 720p and 960p and if so probably more as a placebo than a real difference.

I agree on the odd formats. However, going from 720p to 1080p is a significant improvement, especially if you have a large ( 46" + ) flat panal to view things on.
I would be very interested in this. And for everyone saying its not needed, this is a development forum. Many many many things that are done are "not needed" but still pretty cool. He asked if it could be done, lets stick to if it can, not if it should.

720 from 5 meg camera is already seriously pushing it, almost hack wise. Normally only 8 meg cameras should support it. And im not speaking about 1080...
The sensors usually can't deliver 30 fps at 1080p even if the hardware can encode it (which ive seen no tech specs of,just various "web claims" aka moot stuff)
It's not because its a 5MP sensor etc, its about how much data can go through the sensor after it's captured (that's before the CPU/DSP!!) You have very good 5MP 1080p cameras, because the sensors can handle it. They also cost more. I highly doubt the one in the SGS can handle much more than 720p at 30fps.
i'd rather have the image processing improved than 1080p, since 1080p (if it could be done that is) will be approx the same quality as 720p, use twice the space and need twice the power to decode on other systems.
in fact even the encoder can maybe be optimized. i'm not familiar with the hummingbird, but the OMAP's have TI's own such hardware codecs and while its proprietary you can implement your own codec accelerated by the DSP.
HummingBird's codec produce "very average" 720p H264 mainline (i believe?) at 10-12mbits (!)
Compare with x264 4mbit 720p H264 high profile quality for the same source, it blasts it away quality wise and is 2/2.5x smaller in file size. besides it has a zillion options depending if you want quality, latency etc.
bottom line, if a genius would accelerate x264 via the DSP it would be awesome.
I know the x264 team worked on the OMAP DSP with little success, mostly due to rather cryptic documentation
There are plenty of PC displays which AREN'T 1080P (only cheap ones). 1080p and 720p is optimal for TV's, but not computer displays. There are plenty of computer displays which are 1200 lines vertical resolution.
And I've found a difference between 720p and 1080p, but it's more obvious on larger displays which supports higher resolutions
I'd rather have slow-motion and a proper app that enables video editing/cutting/sound mixing just with Iphone 4.

I'm inclined to agree, theres room for improvement at 720p, its like the same logic as low end cameras and camera phones alike ramping up the pixel count doesn't directly mean better quality..
Plus the phone although it should be able to currently doesn't like playing back 1080p videos...
I'm not saying everyones going to want to watch 1080p on an 800 x 400 panel, just saying you might want to play back what you've just recorded to see how its come out..
Now that I heard you can put Honeycomb 3.0 on the Nook Color, I am thinking of getting it today at B&N.
However, I will be using the device mainly for watching movies and I love to convert movies. I will be converting 720p .mkv movies to .avi format with 1024x600 resolution and 2,000 kbits rate to get the best video quality.
My question is: Can it play .avi files with 1024x600 resolution and 2,000 kbits rate super smooth on Honeycomb?

In the basic 2.1, the recommendation is for MP4 (H.264) at 1,100 kbps. I recently watched Inception at that setting and it was perfect for the Nook Color.
Check out this thread regarding Handbrake settings for the Nook Color: http://forum.xda-developers.com/showthread.php?t=894165
for any kind of hi-res content, you'll want to use hardware accelerated playback. Unfortunately, the chip in the nook only supports a certain video codec and resolution. h.264 basic profile and a max of 800x480. 1100 kbps looks pretty good.
Any other codec or higher resolution will rely on the software renderer, and it will be very choppy.
I created a nook color preset for handbrake you might find helpful. It will convert your 720p movies to the highest quality the nook supports.

You guys just burst my bubble. If the max resolution that it can play is only 800x480, then I guess I will not be buying the Nook Color. Even my HD2 can play mpg4 file that is encoded in 800x480 with 2,000 kbps smooth as butter without problem. If the NC cannot play 1024x600 with 2,000 kbps, then what is the use?
I guess I will have to wait for the Xoom to come out.
800x480 looks great. The nook scales it up to 1024x600, and the pixel density is high enough that you see no pixels. It looks very smooth.
You do realize that the hd2 has a 1ghz snapdragon processor. While we only have an 800mhz stock that can be overclocked to something equivalent. Why would you expect it to do better than the hd2? I would say they would be the same. But if the difference is worth the extra $350 premium then go for it. 854x480 at 1100kbps looks amazing on the nook.
The biggest dissapointment with my Nook is the video playback. Its not horrendous on eclair, but I have absolutely no luck with it on these froyo builds. Probably going to go back to 2.1 soon just so I can at least view some videos again.

I never thought of owning the Nook Color until I heard about being able to put Honeycomb on it. I prematurely got excited and thought that it can do good video playback since my HD2 is excellent at playing 800x480 file at 2,000 kbps encoding. I knew that it can be overclocked to become more powerful. If it can only do 854x480 at 1100 kbps then it is a big disappointment. Beauty is in the eye of the beholder. If 854x480 at 1100 kbps looks good to you, it may not look good to me because of possible pixelation. I want a device that can play full screen resolution with high bit rate. I know that it would require bigger memory card/bigger storage space and slightly consume more power but that is what I am willing to sacrifice.
Well, I guess I have to get either the Xoom or the G-Slate. I don't mind paying extra for it. Just put in some extra work time and I will get a device that I will be happy with.
I love gadgets and love to tinker with them and that is why I enjoy putting all kinds of available OS onto my HD2. I was just about buy the NC just to tinker with it but I guess I will wait until the great people at XDA can somehow get hardware video acceleration on the NC to be able to play videos at higher settings.
Thanks for all the info about the nook's video capability. It was very informative.
DSP support?
What are the chance the DSP will get supported in Froyo/Honeycomb?
So even with hardware acceleration we only get [email protected]

Video quality
Any idea if this would work better if the nook was oc'd to 1.1, I guess once the dsp is fixed maybe that and a 1.1 cpu will work.
While i do lov to play 720p videos on my captivate (its screens is 800x480) it is down scaling those videos... the main reason i do 720p is because thats what tubemate will let me download them as and still work..
That being said he 480p that the NC can so is still a very good picture.. Normal CTR TV's are only 480i dvd's are at 480p and they still look good on my 42" 1080p tv.. not as good as blu-ray but still good.. and thats stretched to 42" were talking about 7"
1080p 42in= 52.45 DPI
1680x1050 20in monitor= 99.06 DPI
NC running 800x480 at 7inch= 133.28 DPI
NC running 1024x600 at 7inch= 169.55 DPI
Now.. looking at those numbers.. so you REALLY need to run at 1024x600? even at the 800x480 your getting less pixelation then you do on a 42inch 1080p tv.. yes the NC is held ALOT closer.. but even so.. its still giving you DVD quiality picture in your hand on a 7inch screen..
The video playback is definitely disappointing. It sucks not being able to just download a video and just watch it.
I'm getting a bit lost from the conflicting opinions. I'm a lazy and VERY not fussy video viewer. My main use of my NC is to watch videos that were originally made for an iPhone.
Bottom line... Now that sound is working in honeycomb to the NC. am I going to be able to watch my simple iphone type videos on my NC if I take it up to honeycomb? Remember. I'm not at all fussy about quality as long as it isn't too terribly jerky.

From what i understand (and thats not much =) currently honeycomb still has NO hardware acceleration for video.. nither does froyo so the best video playing on a NC you can get is currently running a rooted stock rom.. encoded at 800x480 or below.. the iphone 3gs and older all have a screen size of 480x320 so they SHOULD work as long as they were encoded properly (right codec and such)
Although I understand the excitement, this seems like a very premature discussion. Despite the repeated statement that honeycomb is available on the NC, out is in fact not. What you are seeing is actually an SDK build. Software Developers Kit. For development. And the first SDK at that. You are essentially seeing an emulator running on the nook screen.
Before everyone goes nuts I know that is not technically correct, but it is as correct as saying we are running full honeycomb.
After an AOSP build is released we will see a more functional version and eventually probably see better integration with the video hardware. And for my final rain on this parade...I am a professional video content creator. And if you think you are able to see the difference between DVD quality and 2100 stream HD on a 4.3 inch screen, you are mistaken. Or have vision above that of mortal men.
For the record I owned an HD2, now use the Evo and also own a NookColor.

Ok i'm confused by this part...
No one was really talking about the 4.3 inch screen..
ANYWAYS the dvd quality vs 2100 stream HD by that do you mean a 2100/kbps steam?
if thats the case then its not a surprise seeing as 2100/kbps is enough to stream at 480p.... which is dvd quality

OP's original question was about "I will be converting 720p .mkv movies to .avi format with 1024x600 resolution and 2,000 kbits rate to get the best video quality."
Later after some responses he comments he gets better resolution on his HD2 (that is a 4.3" screen) so he will skip the nook.
You still point out a misunderstanding I had now that I go back which is that he is starting with a 720p source but ending up 1024x600. But really this is just makes my point stronger because then we are looking at an even smaller difference in the resolution.
I'm not sure that how many people at here know this fact.
Tegra 2's H.264 decoding is waaaay worse than Hummingbird(Galaxy S)
It cannot run any HD H.264 video HP.
Source?
Tegra2 can decode 720p at AVC HP and 1080p at AVC MP with reasonable/usually bitrates at 30p.
€dit: Just seen that u have the korean model, right? AFAIK the LG-Player isn't supporting the mkv-container,
allthough Tegra 2 would be up for the task (at 720p30 HP) as mentioned earlyer.
You will find out when you get O2X

I think with VLC or RockPlayer you can probably see a difference
How does x264 perform?
I think its the same issue as Adam had with the video/audio desync. Its not a hardware limitation.
I don't get it. I've tried various videos and none of them work properly. However, the demo video files that were on the device (1080p) run perfectly. No frame-skipping at all.
Is there something I'm missing?
I was kind of baffled by this too.
Brilliant playback on the included 1080p files.
So i thought yay lets grab some 1080p trailers from youtube with tubemate.
But alass. not very smooth! Think its indeed the profile that does the trick. or in this case, doesnt.
Next thought. Ok rockplayer will help me out here!.
But i wasnt too impressed with rock on my galaxy s either!.
Loaded rock. but also very crappy. Which is when u think of it, pretty logical.
Why? No hardware support! Rock doesnt even remotely know what a tegra2 soc is. and in fact, NONE of all the video apps do.
So in stead of funky tegra2 hardware decoding, you get software playback.
Ive heard some rumors about nvidia developing an android video player for tegra but i dont know if this is true or not at all.
so unless someone makes a proper video playback app (which in my opinion is way over due already! no offence but theyre all crap if u ask me!) which supports hardware playback AND tegra2 soc, it wont improve very much.
My 2 cents
Ok some more info, apperently Tegra2 isnt very great with high profile encoded. baseline and main profiles should work. more testing to do. Also everything below 1080p high profile should kind of play properly. My eyes are on VLC for android and fingers crossed for them to bring tegra2 suppot and their own great codec sets
Check the Motorola Atrix forum, on XDA (sorry cant link from mobile app), they have basically given up on playing hd h264 files on tegra 2. Such a shame.

Yes indeed. It sucks ass. I have the same unit but then from T-Mobile Netherlands. Video included works like a charm (ofcourse) but own added videos look like they are in slowmotion. 720p, 1080p doesn't mattter same issue.
Extra added flaw? When your record video in Full HD it does not play back on Full HD TV's or BD players. I checked why and found that it actually records in 1920x1088p!!!! Yes 1088P people.
FOTA updates are also not working for the T-Mobile branded unit. Comes back with validation error.
Tegra 2 limitation
Some search on the internet revealed that Tegra 2 supports fully h.264 main profile, but for high profile, it is only 720p 6MB/s, which is then not suitable for a BD. Anyway, I don't have the intention to fill in my 32 GB of storage with just one movie...
Recording in 1088p instead of 1080p is a bit more annoying, you think there could be a solution for that?

Yeah MVK-files can be played with other videoplayers on Market but I've read in reviews that it's awfully "laggy". Saw a video where they tried to play mvk in RockPlayer, i think it was, and damn... looked like 1fps!
I tried to play a mkv file yesterday with the build-in player which crashed my phone.
I installed qqplayer and am pretty satisfied with the result.

What kind of mkv did you try? 1080p?
I keep saying its a software issue causing all these troubles, i have a Adam and since the latest update i saw a improvement on the video playback.
Once we get proper support for mkv it will be awsome

Do you have a video of the adam playing back mkv?
You can search in the thread @ my sig for " Notion Ink Adam Qi Vs Motorola Xoom by Inspiron41 "
I can add that any file that i have MKV to be played has to have the extension changed to AVI and only QQPlayer can run them, if the sound quality is high more than 2 channels the fps rate will be low this happens with either 720p or 1080p. But if i try to run a MP4 file with 1080p it runs very smooth with audio and video sync, so for me its a issue with decoding of MKV.
Oh and the Adam is running froyo no multiprocessor support neither the video apps do.
