[Q] is 720p video possible? - Motorola Droid and Milestone General

i think someone talked about this before but i can't find the thread in searches. is it completely impossible to get 720p video out of the milestone?

likely possible, just depends on how many frames you would like per second...
The camera seems to be high enough quality to capture the pixels you require but the phone may not be able to process/compress the video stream, given the frame rate you may desire.
I'm not totally sure, but I imagine that's going to be the overall consensus.

Cannot be done.
I believe the phone itself couldn't keep up.

No enough hardware for 720p on milestone

I believe once you root the phone and overclock the hardware, it should run video at 720p

is this true?
how would u go about enabling 720p video recording?
that would be awesome!
i have already rooted and overclocked to 900mhz

I don't know if is it possible since we can't even play 720p .mkv videos, which I believe needs less cpu/ram power than recording 720p videos in high frame rate.
Furthermore, Milestone's camera isn't that good at all, why you would want to record a 720p video with a bad camera sensor?

with camera.apk change this is possible?

Playing 720p files is perfectly possible, but recording, hmm maybe at 24 or less FPS so why bother I prefer D1 at 24+ FPS, than laggy 720p,

It should be 720p video recording min requirements are 30 fps rate. Nexus one at best have 25fps. Our phone runs from 30 without root even motorola has specs sheet.. I think it was Verizon who told Motorola not to add 720P video recording. Just to make users upgrade to Droid Incredible and Droid x . In the Froyo update to Droid Last Summer. Milestone will get 720 p video recording in the new update 2.2 os in Europe. You can always talk to Matt from Motorola to verified my statement.

Hi cry3200, could you tell me how do you play 720p .mkv videos??
It's the only thing I wish my Milestone could do and can't get it done. My videos don't play flawlessly whatever video-player/settings I've tried.
I only get 720p+ videos and I would love to play them in my Milestone without having to encode them in lower quality...

Hi there,
first off all i don't need this feature on my phone...
It doesn't make sense to me if the video resolution is higher than the display resolution.
Anyway, no doubt it is quite interesting thing from the technical point of view.
At least some things should be fulfilled:
- hardware support for 720p
- enough bandwitdh on the memory subsystem
- application to handle HD video files
So i took a look into the processors datasheet:
Code:
· XGA - 1024 ´ 768 VESA timings at 60 fps (pixel clock = 63.5 MHz)
· WXGA - 1280 ´ 800 VESA timings at 59.91 fps (pixel clock = 71 MHz)
· SXGA+ - 1400 ´ 1050 direct drive of LCD with minimal blanking at 50 fps (pixel clock = 75
MHz)
· HD 720p - 1280 ´ 720 CEA 861-D timings at 60 fps (pixel clock = 74.25 MHz)
Looks like hardware would basically supporting this.
From my point of view the rest of hardware should be powerful enough to handle it as well (at least it is a SoC with PoP memory).
There's also a high speed connection to the display.
Last but not least the CPU is very similar too the one used on beagleboard.
AFAIK you may play HD on this hardware.
IMHO there might be some trouble on the milestone because of the resolution missmatch.
Please correct me if i'm wrong!
Regards,
scholbert

Just use VPlayer, set the quality in options to Speed or High Quality, and experiment with the buffer for different container types, MKV files should not exceed your card speed I use a class 10 card but the stock is a class 2, but usually I use MP4 720p files that I encode from MKV 1080p, I encode on the GPU so by the time I drink a coffe and smoke a cigarette its almost encoded, original MKV 720p has some audio/video sync issues with VPlayer so I dont use them, but if you overclock to 1.2 or 1.25GHz the sync problems are gone, I dont really remember a bit rate to tell you for encoding, but try with 2000-3000kb/s and see if it works I usually use between 3000-4000kb/s with my card
Just experiment,
EDIT: Forgot to mention, not all of the movies encoded play flawlessly but I'd say that 90 percent of them work, but keep in mind you need to overclock to 1GHz minimum so if you don't want to do that it wont work, and use FroyoMod cause its the fastest and most stable rom available, Gingerbread has problems with VPlayer it just crashes; but the problem is VPlayer itself

Thank you for your answer.
- The only reason i wanted this to work out-of-the-box is to not have to encode, etc.. Just copy the files in SD Card and press Play..
- I am always in 1.1GHz, I will try 1.2GHz..
- I encoded a couple of 720p .mkv files in MP4 with excellent (same I think..) quality with Handbrake and they played absolutely fine in Milestone. I just want to avoid this encoding process.
I will follow your advice and see what happens. First of all I guess I have to change the stock mSD with one faster.

Thanks for all the replies regarding this. I just figured that since the camera sensor has the pixels it should be able to fire out the extra res. I'm not concerned with the screen mismatch as the videos don't get played back on device, they get put on my computer and youtibe, both of which will benefit from the extra pixels.

iPhone 4 now plays 1080p videos easily, then why Galaxy S can't

http://blog.gsmarena.com/iphone-4-now-plays-1080p-videos-easily-does-some-xviddivx-magic-too/
Seems like some people managed to play 1080p on iPhone 4.
SGS has almost the same CPU with better GPU and option for overclock.
What is the reason that is preventing us from playing 1080p? Not good enough app or something else?
1080p on a 4" screen? no thank you.
We just seems to be needing a good codec to play 1080p. So it should just be a software limitation unless the GPU is capped at 720p!

I would never watch 1080p on 4'' screen (even though some people would)
I'm just curios about the hardware.
@Prankey,
I guess SGX 540 can play 1080p if SGX 535 can.
I'll make a wild guess here:
iOS has all the software needed for full hardware acceleration while Android don't.
How is this a development related question?
And I thought galaxy can play 1080 without problems (didnt try though, as its very stupid).
so iPhone display is 960 x 640 pixels?
1080P is 1920 x 1080 pixels
unless it can output HDMI, seems pretty pointless to me.
The screen resolution is 800x480 anyway so the extra resolution does not benefit you at all. It's just a minor convenience to avoid converting the video but you're wasting battery power to decode the video and a lot of space. 720p is enough of a battery and space waster.

1080p isn't even listed as a file which can be played. You can't even upload it via iTunes, so there is no official hardware acceleration built in for 1080p.

You still have to convert the video though for these devices still cause h.264 codec support for mobile devices don't support all of what the codec can do. It's also wasted bit rate as well. It's better to have a lower resolution video with a decent bit rate then it is to have a video with a massive resolution but not enough of a bit rate to smooth out artifacts. this resolution race for videos on mobile phones is a tad stupid.
Rock player plays 1080p for me.
The Video I tried was a bit choppy though but acceptable.
(I guess about 15-18fps). I only tried one Video wich I accidentally loaded on my device.
As far as I now Rock player does not use any GPU acceleration though pretty impressive what this little CPU is capable of.
Definatly plays full hd better then my atom netbook.

I wasn't talking about hardware accelerated 1080p playback. I was talking about how everything in iOS is adapted to support as much of the hardware features as possible, while Android is not adapted to support the SGS hardware in any other way than Samsung just tossing in (semi)working drivers.

1/ there is no point, resolution-wise
2/ with iphone there is a VERY limited range of file formats you CAN actually play, so you will spend half your life converting to a format that apple can control. Most my 1080p movies are mkv format, a format that works on Galaxy S but not on iphone. All my SD movies are Divx and Xvid, again, not compatible with iphone.
Mark.
Well actually we can! Rockplayer can do it so please stop spamming this forum!

Anything that can be done on the iphone 4 can be done on the galaxy s, just needs the right software to be made.
The only difference between the iphone 4 and the GS is the software, the screen, and the galaxy s having one generation newer gpu
Anyway what's the point in this? sd cards have a 4gb filesize limit, 1080p would waste so much battery for no benefit over a 720p file
technical spec yes
real life usage, not so great
wireless N is what i use for my home teather, yes it "works" but load time is horrible, as well as the random cut offs, then waiting for the load time again.... it's a pain in the aussie
it's much more convenient to first copy the entire movie into the hard drive via wireless N, then watch it
but that defeats the entire purpose of streaming a movie

[Q] Possible to mod the camera to record in 1080p ?

Any devs looking at the possibility to record movies in fullhd, 1080p ? I seem to remember I read somewhere that it should be capable of it.
Well if it is capable of recording in full-HD then why wouldn't Samsung themselves implement it so to make more sales?

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..

Can the Nook Color play videos encoded in 1024x600 and 2,000 kbits rate?

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?

So that would seem to be a significant barrier to your plan ;-)!
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.

Horrible H.264 decoding

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.

720p on NC

I had NC with Cyanogen Mod 7. I couldn't get 720p to work on it.
Now that my NC got broken, I'm thinking of buying it again. Is there anything new about 720p?
i'd like to know too. as from the day after tomorrow i will be a Nook owner too
In this price range you're still not going to find a decent tablet with 720p capabilities. If your only goal is videos, start taking a look at the chinese tablets and the archos. If you want a tablet with the ability to do it, but not perfectly, then the nook is your best choice.
I say not perfectly, as I found that 720p video was better on the .29kernel (1300mhz) with Moboplayer. 720p works okay with overclock and Moboplayer on the .32 kernel though...
That said, 720p is overkill for that small of a screen.

I would see the tablet being worth it if it was 1080p but I'm not sure aboutv720

Um what? ----
Basically no, there isn't any news on the video playback front. The new B&N update's codec had the same file limitations that we had previously, so we lack the codecs for 720p (like an Archos has).
If you want 720p playback get a used Galaxy Tab.
It really isn't a problem for me to watch 720p on NC's screen, but if it was able to do it, it would save the hassle of converting the videos and movies I download for my PC.
I will try moboplayer with OC.

At least 1350 isn't enough to run 720p videos. I tried to set up tversity but couldn't get it to transcode.. Didn't feel like setting up either of the free alternatives either, lots of fuzzing with config files..
Technical question for you re-encoding guys. Does the 854 limit count after or before anamorphic scaling? So is it possible to play back pal 2.3 picture format movies? Native resolution 720x445, stretches to 1024 wide on-screen..
