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?

Looking at the Honeycomb thread:
Doesn't work:
-Sound (sadly! Despite my efforts the last hours I didn't get it working properly yet)
-DSP e.g. no hardware video decoding

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.

Yes, I went back and looked up your thread since I successfully used your presets and wanted to say thanks. They worked great and the results made a long flight from Denver to Orlando very enjoyable !

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.

There's no hardware video decoding on Froyo yet.

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.

Considering the Nook!

Hi guys!
Im in deep love with the nook! And im not too far from buying one.
But im a bit confused! What is the nook able to do with the available custom rom?
I mean, will i be able to play Avi movies with no problems if i install a custom rom? i will write down my needs and you can answer whether theyr possible or not lol, probably easier.
- Readin documents Pdf mainly
- Music (TuneIn aswell)
- Light games such as angry birds, tank hero
- MOVIES Avi, mkv and so on.
Idc if i have to root or install a custom rom. I just need to know if the needs is possible in any way..
Thanks in advance and sorry for my english.

The froyo rom can play avi format along with many other formats. The stock rom can only play mp4 format. If you don't want to root the device, you can convert the video file by using handbrake, a free video conversion software. Nook is a good device for browsing the web and watch okay quality videos.
Sent from my PC36100 using XDA App

Do you have a nook sir?
If so, can you tell me if the froyo rom will help me doing all the jobs PERFECTLY?

64 views and no answers? :s

Froyo is not ready for prime time - however NC rooted with 2.1 is more than enough to meet your listed needs -it can play various video formats - just need to get the right player - i use mVideoPlayer and it plays mp4 plus the added plus of importing subtitle files. RockPlayer plays a whole slew of formats including avi and mkvs. I use handbrake to transcode my avi files to mp4 coz who wants to be lugging that huge file size around?

I would recommend rooting and using the stock ROM. I would only use Froyo if you need to watch flash video. (You'll definitely need to root to get the Market, Gmail, and Youtube vidoes)
(Overclocking it is a nice bonus to gain some more speed.)
Edit: and the 64 views is likely a lot of bots browsing the forums.

Okay. I have one clear last question:
Can it play AVI's (Notice i need it to play avis and not mp4s) With NO LAG on a stable rom, at the moment? Thanks!

I have two nook colors. One for my wife; and one for me. You can watch avi videos on the froyo rom. It is actually pretty smooth. I like the froyo rom because it is very stable and fast. The only issue is that you have to put it to sleep and wake it up when the screen becomes a bit lagging. You can view PDF files by using acrobat reader. For a 250 device, it is well worth.

Do the avi videos LAG? I mean, the pictures cant follow the sound or sumthing?

I too am considering the Nook Color. Sounds like a great entry-level tablet, that once rooted, can give you a great Android Experience at a mere fraction of the cost of newer tablets.
However, I'm likely to wait until the CM team comes out with an official ROM for the thing, as I value stability and smoothness in my devices.
I'm really exited to hear they may even be able to use the on-chip Bluetooth (the chip used has been shown to have Bluetooth hardware, and there has been at least one successful test). Using the Nook Color and a Bluetooth headset to use Skype would be a killer feature!
I'm keeping an eye on developments, and if there ever is a CM ROM for the NC, I'm very likely to buy one.

I didn't notice the lag when I watched the avi video. I also converted the avi videos to m4v format and it worked great from the stock rom
Sent from my PC36100 using XDA App

Depends on your avi bitrate and resolution. At 800kbps and 640x360 rock player is smooth and good quality
Note trying to play full 1080 p on tablet is not ideal - after all you only have a 7 inch screen and a lower screen res

I think BT has now been enabled -- but with problems. Let's hope the community finds a way to pair (properly) a blutooth headset.

Woohoo raised this thread from the dead for no apparent reason! I'm fairly sure the OP has either gotten a nook so he'd already be reading about BT in the forums, or he's moved on to something else. Either way why resurrect this thread?

I apologize. discovered the thread via search engine.... did not pause to verify the date!

I regret buying Nook

Guys, I want to share with you
I finally realize that the money I spend out to buy nook color is not worth it. beside used for browsing, youtube, playing game, I also want to use it for playing video, however when I try to play MKV files, the video and sound is out of sync, and when I try to play AVI file in mobo player, it can't be played and I switch to use QQPlayer and it plays fine however some frame is skipping so the video seems a bit laggy. THIS IS SO DISAPPOINTING, nowadays most video files are in MKV format, why this tablet is not supporting to play MKV video compare to other tablets?
FOr the same price I can get tabulet (tablet from china), it can play video file well compare to nook, the only problems maybe it will have slower update compare to phiremod. Now tell me, why you wanna buy a Nook color while the same amount of money can be used to buy other tablets or top up a bit to buy other tablet that can play video files.

What speed is your SD? I am running Gingerbread on a 16GB class 6 card and have no issues playing AVI files in Moboplayer.
If I was looking to buy a tablet today I would not buy a Nook, got mine for $200. But would instead buy the Asus Transformer if they ever get any in stock.

I also have no problem playing videos. That said, I've never tried an MKV file, as I've never heard of it. So I definitely can't support your assertion that most videos are in the format these days. But I'll have to trust you that the NC has troubles playing it.

I have no trouble playing mkv files using mobo player. I am using CM7 with OC Kernel 04/24.

Im watching the rite now on my nook color as we speak. Its very smooth and I'm using Mobo. So I dont see what you are talking about

Nook Color is an ereader that some people have converted to general tablet use. There is no reason why it would have its own video player.

Hopefully it's still not too late for you to return the Nook. The Nook was never known for it's multimedia capabilities. It was designed and marketed as an e-Reader. It's great that the dev community is able to enhance the capabilities of the device. Good luck!

i am using phiremod 6.2 with 720p quality, how about yours? I guess must be 480p quality

I got my NV on Saturday then rooted it and put CM7.0.2 stable on the emmc (not SD). I converted three movies in Handbrake using recommended settings found on XDA to MP4. I use Rockplayer and it works great. The movies are about 900mb in size with running length about 1hr 45 min and no problems.
The only video/audio sync issue I saw was using MLB.TV app but the is a common problem with MLB app. Playon MLB app works fine.

Phiremod 6.2 IS CM7, with some extra skinning.
Anyway, a little research will go a long way. The Nook does not have the hardware to play most 720P movie; though Mobo player will play a few quite well. The built in hardware decoding can only do up to 480P, and Mobo player, using certain CPU decoding pieces, can do some 720P.
BUt as it is, you would have known all this if you had just done some research beforehand. Video on the nook is a hot topic, and not something you would have to dig deep to find out about, including its weaknesses.
And please... what a load about the Chinese players. Yes, you can get a crap tablet for $150... that has a low res resistive screen, Android 2.1, no community, and no support (oh, and looks like a bad iPad knockoff to boot). But please, since you alone seem to know about them, please point us to another knockoff tablet that has such an amazing screen, great hardware (all that can hit 1.1Ghz, and most that can hit 1.3Ghz), for $200-$225 (best buy was having a $25 gift card sale recently)..

same, try rockplayer, works for me.. running rooted stock and draggin-dropping .avi's to a class 16 class 2 sd, they play fine.

if you know nothing about tabulet (china tablet that rebrand by indonesia company), then don't say anything. Though it is 700mhz it can play video well,
so what if nook can be overclocked to 1,3Ghz? Is there so many apps that is running in background that need the speed? It is not a pc, it is a tablet mostly for single or two task for simple like listening to music while reading, it is not for running many apps behind the scene such as rendering video or encoding
the different between those china tablet and nook is their graphic capabilities. Those china tablet, viewsonic tablet or asus tablet has better VGA and hardware decoding features that enable them to play video smoothly, unlike nook which is merely an over expensive e-reader that both expensive and yet unable to play video files well. And FYI, tabulet or china tablet is now moving to capacitive, though not much is capacitive but most new product is in capacitive screen, so forget about your idea that telling you all china tablet is resistive!

So go buy a "china tablet" then. What's the point in whining about something that everyone knows about beside trolling?

Indeed. Everywhere I turn, I'm seeing more and more [email protected] tablets that are either running an old version of Android, have paltry memory, low res, horrible battery life, etc. Often times, it's a combination of ALL of these things. DealExtreme carries several pretty horrible tablets.
Innosia: That sucks that the nook isn't satisfying your needs. I can understand your frustration. What are you expecting by whining about it here? Do you want us to pass the plate around to fund a replacement for you? The only thing you're going to get, particularly here, is a lot of indignation. Again, that sucks that it doesn't do what you need it to do. Sell the damned thing on eBay or Craigslist before it declines further in value and buy yourself something that suits your needs.

I dont really see what the big deal is, reencode the videos. Itunes does that for IPOD/ipad devices, why cant you do that for the nook? Are you just saying your too lazy to use a template and reencode some videos you want to watch?
The nook was never marketed for its multimedia skills. The fact that it has a hw decoder at all, is pretty lucky. for 250 its the best device i found out there. it does everything i would want out of it. If i wanted more, i would have bought an IPAD.

I am not rich and I already cheated to buy nook and not able to afford a new tablet unless selling this one, I am not whining or trolling, what I am trying to point out here is for newbie who want to buy nook color, hopes they dont fall to the trap in buying nook color if they need playing video. I am just warning them, so they can use their money wisely. Be careful for B&N over expensive e-reader sales team

What were you expecting from a hack eReader?
Be serious. Its an ereader. All the rest is gravy. Whatever else you can do with it (besides read books) is awesome. Stop whining long enough to understand what you DID buy and what you DIDN'T buy. When you recognize the absolute awesomeness of what you bought has become you'll thank these fine folks for all their hard work.
Thanks everyone for all the hard work, done on your own time, for nothing in return.
I really appreciate it! Cheers m8s.

It sounds like you want a video-player more than a tablet. I'm wondering why you would come on here to post about how bad the NC is for your purposes? From all the posts I read it seems like you could easily read on here about what video types work and how to get them working smoothly. If you want something working out of the box, then return the nook and get it. If you want to fiddle with the thing until things work, then keep the NC. Simple

Sell it on eBay for about as much as you bought it for. They're still going for pretty high.

As has already been pointed out, re-encoding the video into an appropriate format does wonders for allowing it to play properly on the non-multimedia optimized nook.
FWIW, I've also noticed that different players have better luck with different formats. I currently have 3 video players installed (yx, Vital, and QQ) and have found that one of them will almost always properly play any of the couple hundred video's I already have on my media server.
Between iPhones, Xbox, Samsung Galaxy Tab, and some random other netbooks and devices, I've gotten a lot of experience at getting video to work on a lot of platforms. It would be great if AirVideo decided to do an Android client.

ROM for smoothest video playback

What ROM can I flash to playback video as smoothly as possible? I see in some discussion people saying their Tabs can play back 1080p high profile MKV's perfectly, while in others, such as the Overcome ROM discussion, people are saying that they're seeing a lot of stuttering invideo.

Most people are talking ****, there's also no point in playing 1080p movies on the tab, they aren't going to look any better than 720p movies (which play just fine) real high profile 1080p rips are 15-25gb so you wouldn't even be able to get them on the tab.
At the moment, the latest and greatest is overcome gold, mix that with the oc kernel and you'll be fine playing back high bitrate 720 movies

I have found the old line of overcome better than 2.0 for some things. It has been more stable for me and I never has any problems with video play back. I've haven't tried 1080 since I've never seen the point: more storage and zero perceivable quality improvement.
The source and transcoding are far more important.
Sent from my GT-P1000 using Tapatalk

The reason I asked about 1080 is just because a lot of my files are already ripped as 1080, and I don't want to have to transcode my files to play them back.

any decent rom will do, even the stock one. Overclocked kernels on ext4 filesystem works better though. Watching 1080p movies on Overcome Gold + koxudaxi kernel.

[Q] video playback on latest cm7?

Hey guys,
I think I read somewhere that the nook color CM7 nightly builds got the functionality of hardware supported video playback(?) Is this true? Does this mean I can play .avi (DivX and xvid) files smoothly using something like yx player/rock player without having to convert it to .mp4?
I am contemplating a nook color. All the other features seem great. Looks fun to mess around with. A good video playback would be an additional plus for me

I have had pretty good luck using Moboplayer and a bunch of videos I made with Handbrake for my iPod touch using the default iPod Touch profile. They are playing well and look good. Handbrake is free and it works pretty fast. I know you said you did not want to do MP4 but you might take a look at retranscoding.
I'm using CM7 nightly 102.
HTH,
Paul

As good as Stock 1.1.0?

pgrunwald, have you tried .avi files?

Okay. Hardware Acceleration will only work with specifically encoded for Nook Mp4's. (Yes videos for ipod touch, etc... will work, as their resolution is under the maximum the nook can handle) For more information as it's just to much to type... Look up the video threads by Dalingrin and Chisleu, they have all the information on that.
Now .Avi files. Play fine in software mode in any of the players you listed. That said, I'm gathering if you're watching an avi file, it's not over 720p, as that would just be stupid... But common "scene" releases of unmentioned files, do play fine.
720p Mkv's however absolutely require the OC kernel and in my current experience, the .29 kernel based CM7. The .32 kernel at this point seems to have trouble with 720p, it's not unwatchable, but it did stutter from time to time on my NC.

I'm using vitalplayer neon and it works fine for xvid avis. I didn't convert anything or check anything. I just used a file that I had downloaded to watch on my desktop. It stuttered a bit at the start but played smoothly after that. I was amazed. NC keeps doing more. I wasn't even overclocked at the time.

720p Mkv's however absolutely require the OC kernel and in my current experience, the .29 kernel based CM7. The .32 kernel at this point seems to have trouble with 720p, it's not unwatchable, but it did stutter from time to time on my NC.

Could you elaborate on this a bit more please (bitrate, framerate etc.)? I could never play 720p on my Nook. Currently I have one of the recent CM7 nightlies, and even OC'd to 1300 no player (Mobo, Rock, etc.) can't handle any of my 720p mkv's properly. It was also the case with OC'd .29 kernel. It's not that it just stutters every now and then; it's a heavily slowed down slideshow.

Hey guys,
I think I read somewhere that the nook color CM7 nightly builds got the functionality of hardware supported video playback(?) Is this true? Does this mean I can play .avi (DivX and xvid) files smoothly using something like yx player/rock player without having to convert it to .mp4?
I am contemplating a nook color. All the other features seem great. Looks fun to mess around with. A good video playback would be an additional plus for me

Videos work great on Nook color CM7.1 nightlies. I use the built-in player and use handbrake to convert my videos.

To be honest, I can't really give specifics as the files are long gone that I did use. I was fully able to watch things like 720p trailers (Pirates of the Carribean) and the anime series Kaiji 2nd in Mkv at 720p.
If I get a chance I'll take another look.

I was looking to see if they would play well without the converting process
but thanks anyways.

Well if nothing else, I can guarantee playback of anything under 720p without encoding.
Anything above that is honestly overkill, not only for size of the file, but for the size of the screen; you just won't see a difference between a properly encoded dvdrip and a 720p bluray-rip.
That said, if you're like me, where you have certain files that are already encoded at 720p and would rather not "re-encode" or "re-obtain" them, then I can honestly say (in my experience) that the .29 kernel nightlies or Phiremod 6.2 with OC kernel (4/24) has played 720p files fine in Moboplayer. Not only has it played them fine, but it's not had a problem with soft-subtitles. Again though, this is from my experience in the past and I've been switching between .29 and .32 kernels, so I've been avoiding 720p files like the plague.
.32 kernel may be able to play 720p in the near future however, Dalingrin has responded a couple of times to my one man complaint team about the difference in video playback in the two kernels, and he's said that he is currently working on some major overhauls of the system that may or may not help address this issue.

so what I gather from here is that it handles video fine, even .avi as long as it isn't 720p? I also read something about it handling flash video fine @ 800mhz, 720p..?
here's the article:

RE AVI - I'm sorry, I have not had time.
I did make a handbrake MP4 file using this profile and it played great: http://forum.xda-developers.com/showthread.php?t=894165&highlight=handbrake

Flash video is a whole 'nother ball park. Again, I find .29 kernel to be the best at handling flash and have personally had problems with .32's kernel for longer videos.
That said, I'm one of the only few complaining (possibly the only one), so it's possible it's just me or my source sites/files.
720p flash I'm going to assume to be dodgy at best, there are few tablets on the market that I know of (i.e tegra 2 processor) that still have trouble with 720p flash videos.
That said, flash videos of Standard quality look fine, and the youtube app allows you to play HD (I'm assuming it's 480p) videos without fail and look very nice.

use rockplayer lite

I completely understand not wanting to reencode your videos but keep something in mind. If the video can play in the stock video player then it will be much, much better on your battery life. If a video plays in the stock video player then all the decoding can be done with the DSP co-processor. Leaving the CPU sit nearly idle which will result in dramatically less power consumption. Just something to consider.
And yes, better video playback may be coming to CM7 in the near future if I can get a some changes in. Perhaps even DSP 720p decoding...but shh, you didn't hear that from me. Oh and maybe even *some* flash hardware acceleration though I won't know if will work until I can test it since its closed source.
Don't get your hopes up for the last two because they may or may not work with the changes I have planned.

it's been really cruel of you to have woken up those hopes!!!! After all that time I reconciled with the fact I have to reencode vids...
Keeping my fingers crossed. If you achieve that, I am going to write a script which keeps tapping "donate to Dalingrin" at Nook Tweaks every time I watch 720p

Haha, even with 720p support you will still likely need to reencode many of your videos due to the codecs being picky.
