watch video! playing back 720p videos in avi/dvix and mkv formats
Notion Ink Adam vs. Motorola Xoom - HD Video Playback
Thanks a lot for doing this. To those wondering the Planet earth clip in question is from the first episodes introduction and is usually referred to as the "killa sample" when in 1080p because of the insane bitrate spike when the birds start flying. The idea is, if your device can play this it can play anything. The sample I sent to inspiron41 was in 720p.
Here are the details of the Planet earth clip:

As you can see, VERY high quality for a 720p clip. The bitrate actually spikes from around 4000Kb/s to a high of around 22000Kb/s during the bird scene.
It don't look good.
Thank you both for doing this, it goes a long way to assuage my fears of buying the Xoom and it not being able to handle anything I can throw at it.
Do you think at any point in the future the need to convert will go?
I'm hoping for a VLC for Xoom is released shortly.
I have little patience with converting media.
I just finished playing 2 hours of HD 720p MKV video files on my xoom on QQ player and it worked flawlessly!
Anime on the go just got better!
When I get home I try the HDMI out.

Can you post the details of the video? Download this:
http://mediainfo.sourceforge.net/en
and open it and then drag the mkv file into the window. Then select View>Text and copy the Video and Audio sections.
i'm guessing that QQplayer isnt even optimized for Tegra II chips. would love to see what it could do if it was optimized
Ins and outs of video on the Xoom
@muyoso
The so-call "killa sampla" clip is commonly known as a BADLY encoded clip because the bitrate being used was outrageous. Yes, the "flock flying" sequence takes more bits and will cause a spike, but it's not a particularly demanding scene. There are scenes in the Planet Earth series that have much higher bit spikes. Note that the bitrate for the clip (6.4Mb/s) is only slightly higher than the avg bitrate assigned to the whole movie (5.6Mb/s).
Your 720p clip is badly coded as well. For one, there is no need to use L5.1 for the 720p res, especially when the targetted playback platform is a mobile device. For 720p, you should've used L3.1, and keep the x264 default of ref=3 rather than jacking it to ref=6 (or 9, if the level param takes precedence). For more info about x264's level parameter,
en.wikipedia.org/wiki/H.264/MPEG-4_AVC#Levels
What was proven in your clip is that the Xoom (and Adam) can't play badly encoded MKVs, or MKV videos that were intended for the PC platform, which isn't surprising. Personally, I think it's a bit naive and unrealistic to expect PC-level video-decoding performance from this generation of tablets. Given that this is a tech forum, my suggestion for all concerned is to TECH UP and find a good conversion routine for your downloaded vids. Either that, or wait until next year for the quad-cores to show up.
I've written a Windows script package to optimize video for mobile devices, which can handle most common formats (excluding WMV). It uses x264 for the encoding and is very fast. It can also recode multichannel audio (AC3/FLAC/DTS/PCM) to either stereo MP3 or AAC, and takes only minutes to do. It's noob friendly; drag the video(s) on top of the script and drop it, and that's it.
Right now, it uses the MKV container. I'm hoping that CorePlayer for Android will show up soon, which'll provide MKV support & NEON-accel for H.264. If that doesn't happen, I'll rewrite the script to use MP4 container. MP4 has more constraints than MKV (only AAC audio, no bitmap subtitles), and I prefer to stick to MKV.
Drop your PE clip onto the script and let it recode. My bet is that this will fare much better on the mentioned tablets.
The script package is posted here,

So, wait, the Notion Ink Adam cannot play high profile 720p video?
We need a definitive answer here.
Some people are saying that the Adam couldn't play high profile 720p video but it could after a software update.
That planet earth sample is terrible for actually testing video playback. It was encoded using unrealistic settings. 9 reference frames? I can't imagine a situation where you would need that many.
We need a sample, encoded in 720p h.264, using 3 reference frames, 3 b-frames, weighted p-frames and adaptive b-frames.
>So, wait, the Notion Ink Adam cannot play high profile 720p video?
Let's find out.
The 720p clips below are from the first 1:52 from Planet Earth 01 From Pole to Pole (same as muyoso's), encoded in one-pass CRF mode using x264cli w/ params: --crf 21 --level 3.1 --tune film --preset medium (using the aforementioned script). Bog standard, nothing weird. Avg bitrate is at 5.4Mb/s.
The first clip uses MKV container. It should play in hardware (accelerated) mode using Rockplayer Universal or similar, or software mode otherwise. The second clip is the same as the first, but remuxed to MP4. It should play w/ default Android player. Let me know if Xoom/Adam owners can play either, and how well.

Until the players are optimized for tegra, or a new app comes out
on my atrix (tegra2) a 1080p video plays just fine stock, but using qqplayer or rockplayer it stutters, so we will be saved soon i am sure
the video that i refer too is linked below
full 1080p, 10mbps ! (BASELINE PROFILE)

maybe you can answer me, im curious
can the xoom play 720p or 1080p high profile (or anything thats not baseline)
I know it cant, but is the reason that the tegra cant handle it, or is it a software issue (that can be resolved with apps/codecs)

That seems to still be the big question.
Since the tegra can handle b frames cabac is the primary element in main profile that it can not handle. I would be interested to do a comparison of the same clip with cabac off.
Sent from my Xoom using XDA App
My main concern at the moment (in regard of video playback) is:
1. There is already a lot of post about it here and I have not this issue being officially addressed by any of the three companies.
2. By the time issue is resolved new Xoom might be much cheaper.
3. What if issue is not resolved? How much will Xoom loose in value?
4. If any of coming Tegra 2 based tablets will hold additional chip + own player... who (from general public) will want to buy xoom (and for how much).
For me $800 is quite a lot and I have to take under consideration simple depreciation... I will want to get a newer tablet (maybe next year) so issue of getting money back is important.
Yes, I was hoping for PC like performance (especially that this is exactly how Xoom is being presented since few weeks/months)
No, I do not had/have/will have an iPad.
No, I do not have time (nor knowledge) to play with video format - all I want is to go to XYlinks.org page, make my download and watch the same way on tablet as I do now on my desktop or netbook (preferably form NAS drive). And most of the 720p stuff available to download is mkv high profile (for PC).
Video playback is very BIG issue. I have no doubt that all the rest will be sorted with updates as they are issues of software - video... I do not think so.
It is not me who started to compare xoom and honeycomb to PC experience but companies behind this product themselves.
@JanetPanic
Have you tried the clips I posted? Do they not work, and if not, what was the error encountered?
@galtom
You should only be concerned if you've bought a Xoom. And if you've bought one--on release day, at full MSRP--then why the heck do you worry about resale value? You already know that you'll be lucky to get half of what you paid when you resell it.
Lastly, if you don't care about technical aspects of HD videos, or finding a tech solution, why are you posting in this thread? This isn't a rant thread for Xoom owners having buyer's remorse.

@Digital Man
Spoken like a true technophobe. Unlike your binary view of the world, not everybody is a hater or a fanboy. XDA is a technical forum, and one would expect for people to look for tech solutions to tech problems.
Yes, the Xoom is deficient on video playback. My opinion is that it's mostly a software (read: fixable) issue, which will be remedied when better media players come online. One I've mentioned is Coreplayer for Android, which will have comprehensive format support (aside from AC3) and hardware accelerated support for Tegra2. We all know that there is little tab-specific Android software available right now. That will come.
Despite what the official Moto line is, I'm fairly confident the Tegra2 can do 720p high profile, as long as the encode uses default parameters. Some so-called scene rips don't. If you want to watch these, you'll need to re-encode. That's just the way it is, until the quad-cores get to market.
As for 1080p HP videos, there are other constraints that make them impractical for watching on tablets other than chip capability. A typical 1080p rip averages around 10GB, and takes around 30+ minutes to transfer to flash. So unless you like to watch the same video over and over, swapping 1080p vids in and out of int storage sounds pretty unappealing to me. Ditto for the SD slot, assuming once it's working. Over wifi? You've got to be kidding.
The reality is that 720p is the most feasible resolution for tablets, considering their storage constraints, and the constraints of wifi (yes, you can stream 720p as-is over a good wifi connection).

Correct me if I'm wrong, but Tegra 2 on which these tablets are based doesn't do NEON.

LOL! Exactly my point. Look guys, the only product of Apple Inc I had was second gen of iPod, since my Wife got herself a while back an iPhone and forced me to install iTunes I have promised myself solemnly - never, ever again anything like it.
So, I am all for Xoom (and the likes) so they can succeed, but on the other hand I do not want to same problems and frustration.
This is not a first thread about video issue and I can bet even people who had never heard of XDA but bought Xoom are now puzzled and are probably thinking - what is wrong? It was supposed to play HD video and it is not (Mr Average Joe is not going to even know about all this HD gibberish - 720p. 1080p that is it). It says in the ad it plays 720p. and.... at home it is not.
With every passing day I am worried that issue is BIG since it has not been addressed nor by any "gadget web site" nor by (what is more important) by any of the involved companies... With iPad2 out now I would think it would be fair to say how the things are and what customers are to expect.
Knowing 720p High profile is not coming to Tegra 2 I still would buy it and would not get furious afterwards that I have been mislead (or simply kept in the dark just to make me buy it). With no information I can not make a conscious decision about purchase - and that is all I require.
To summarize:
As much as this forum is AWESOME and I value every single opinion (and I am honestly grateful for it) this one has to be addressed by BIG BOYS as "we" (hi, hi, hi) have only our privet opinions about it with nothing to support them :-(
Video format compatibility.
I want to buy a sports camera and be able to use the honeycomb movie editor to edit the footage. I can understand why my old one couldn't edit it, as it recorded in MOV format (Apple proprietary), so I sold it.
However thinking of the Kodak Playsport XZ5, and downloaded some MP4 sample footage, which I assumed could be edited.. Nope...
Anyone know why Android can't seem to edit anything unless it was created on Android.. (it's almost as bad as Apple devices only editing video from Apple devices..)
The same footage is here: (18MB)
http://www.steves-digicams.com/camera-reviews/kodak/playsport-zx5/101_0002.MP4
Anyone know a waterproof sports camera that DOES record in a Android friendly format?

Tegra 2 is not very friendly with 1080p videos - either reconvert the video (threads can be found here about settings, codecs etc.) or get a Tegra 3 device
I'm not a video expert, but while investigating formatting for ripping movies to play on my Android devices, I found the h.264 video codec was the most compatible. That said, I can't imagine doing much video processing on my Transformer. It's cool, but by no means a desktop/ laptop replacement.
H.264 IS AVC/AAC isn't it?
This is what the Kodak Playsport ZX5 camera is producing.....
Anyone have one, and can record some 720p to try on a Transformer?
Because its a tablet and NOT a computer.

I don't see your point. I realise it's not a computer, which is the whole point of me trying to find a waterproof sports camera that records in a format the Transformers movie editing software understands, as I can't transcode it on the tablet itself....
What was your point?

I think his point was that some tools are better suited for certain jobs while others are not. Today's tablets (particularly ones based on the Android OS) are not very well suited for things like video editing. Sure, there is a video editing program there that does a decent job of rudimentary cutting on the Transformer's already crappy recorded video footage, but for using it to edit movies/videos recorded by an external device might not be the best.
Even the cheapest laptop computer (that costs less than the Transformer I might add) could do a better job with proper software and hardware acceleration.
That being said, if you are well and determined to use a tablet to edit, I'm sure someone here can help you with a solution. My guess is you will probably need some other device to transcode before editing.
I will only buy something ilthat is compatible.
I only have two requirements.
1. Its video output is in a compatible format
2, its waterproof.

No, it's a common misconception. H264 is MP4, but MP4 is not H264. MP4 is a suite protocols. H264=MP4 Part 10. Here's the full vomit:
http://en.wikipedia.org/wiki/MPEG-4_Part_14
Anyway, 3GP, MOV, and MP4 are all MP4, but may or may not be H264/AAC.
FYI: Canon uses H264/with sowt/AIFF audio, which is a semi-proprietary Apple format (sowt is just a PCM/Wave variant). It sucks because it seems that the only thing that will play it is Apple crap or Windows 7. Most of the embedded hardware players (e.g. LG TVs/PS3) drop the audio. I don't know if Canon just didn't want to pony up the money for AAC or was trying to be a purist.
I've been toying with a lossless conversion, but I can't find any documentation on either sowt or twos. I have managed to demux the stream. The Apple stuff all refers to AIFF, which is a different format. I'm really annoyed with Canon, because generally their stuff is really good.

The problem I have, is what I consider to be about as close to ISO standard format as there is i.e.
H.264/AVC video (LC profile)
AAC Audio
MP4 container
Can't be played or edited on the transfomer. Surely it doesn't get any standard than H.264/LC with AAC in a MP4 container does it?
Well, got some 720p 60FPS and 720p 30fps footage from a test camera, and the Transformer plays the video just fine, however bizarrely Movie Studio is incapable of editing it.
I have come to the conclusion tha Movie Studio in Honeycomb is ****e.. Lets home ICS sorts out some of it's problems, and makes it more of an iMovie competitor....
Raised an Android defect: http://code.google.com/p/android/issues/detail?id=22426
the damn tegra 2 cpu has 100mflops power... compare that to a pentium 4 from 2003(northwood 3.0ghz) 6500mflops
my i7 pumps 75,000mflops
it will take the transformer WEEKS TO REENCODE ANY SORT OF MEDIA. It can barely play 1080p let alone RENDER it. good luck.

This.
Not to mention that you're limited to 1 GB of memory, and only about 700MB of it is available to apps. A decent video editing workstation these days will have at least 8GB, which is just barely sufficient for editing an hour long 720p movie. You can certainly attempt to edit videos on much less memory, but again the performance would be atrocious.
Not to mention what that would do to the battery life if you trip over the cable .
Can't say that I imagine a lot of people in powerful money pockets wanting anyone at home having the ability to do such stuff anyway, if there's any chance of e.g. ripping a Blu-Ray wit the same kit.

???? Has school kicked out or something, as I really can't comprehend how dumb these last few comments are.
the whole point of picking a video camera that records in the correct format IS SO YOU DON'T HAVE TO TRANSCODE. that is the whole point of this thread, You can't transcode on a tablet, so it's crucial to pick a device that records in a compatible format... If it's in the correct format, then it's trivial to trim and splice footage in a simple movie editor like Honeycomb's Movie Studio.
Some people really are so thick it's unbelievable...

No, just the typical xda idiots talking about **** above their heads. Lol'd pretty hard at the mflops post. I really miss the "developers" part of "xda-developers" :sigh:.
I wouldn't expect Movie Studio to add any real support for it. Movie Studio was a gimmick app to show off honeycomb, made for people who want to mess around with stuff recorded on device. Give it some more time and I'm sure we'll get more professional video editing software (for a price).
There is no way you are going to be able to edit HD video at a reasonable bitrate (at any profile) on an ARM device. You would need a native app that talked directly to the handful of CUDA cores in the tegra to do this, and there is not enough memory to hold more than a few seconds of uncompressed video on your timeline for a preview (not to mention the amount of virtual nand cache you would need).
Tegra 2 has some hardware DECODING of avc/h.264, but realtime encoding is simply not a possibility for even tegra 3.
I share the desire for an awesome NLE on android, but its gonna take a few years for the tech to get there.
/EDIT
To answer the first part of your question, it is possible to edit using the honeycomb app, but you will need to transcode (and lose a lot of quality). I doubt it would suit your needs, as at that point youd be better off just using windows movie maker/imovie

I think you don't understand how things work.
IF (and that's the original point of this thread), the format is correct, then you don't do any encoding/decoding/transcoding.
Trimming/Splicing is all that's required, along with rendering a picture and transitions and adding a audio track.
This is EXACTLY what iMovie does, and Transformer is perfectly capable of doing so to. AS ALONG AS THE VIDEO IS IN THE CORRECT FORMAT.
CrazyPeter is correct... if the video is encoded to be played back on the device then it can also edit it. You do not need to store the entire video in memory or transcode it, you can merely store positions of the sliced clips in memory as a frame offset of the original video file.. then trim/slice the video together when its' done (which *doesn't* require encoding). It gets iffy when you want to add transitions, text etc into the project but for *just* trimming and slicing it can work.

In agreement, i was referring to non-linear editing, which no tablet can do today. this virtualdub-like functionality certainly could work. you'd just need to find a way to hook into the hardware decoding capabilities of the tegra2 i would guess.

Pretty sure the SIII has a better mic than the SII. So if you hacked the SIII I presume the quality would be better.
Stock values:
Galaxy S: 16000Hz 62900bps
Galaxy S2: 16000Hz 629000bps
Galaxy S3: 48000Hz 128Kbps
Mainly the frequency, from 16000 to 48000, improvement is very noticeable
There is no need to touch audio values now, power button as shutter will be my priority

Really? I suppose that is now on ICS, with GB values were as I said
Um, have you guys checked out the phonearena videos? They mirror the gsmarena ones. The audio, at least on the prototypes, are bad, even for whatever bitrate/frequency limitations. This seems like a false since of security, since it won't change anything if the source itself is bad. It'll will just sound clearer, the badness that is.
http://www.phonearena.com/reviews/Samsung-Galaxy-S-III-Preview_id3029/page/3
It might be recorded right by the software, but if the microphone sucks, that doesn't really matter. Unless you can attach a better microphone.
I'm still waiting to see a video that isn't trying to capture something that even build in mics in the best camcorders would fail at. So it might still turn out to be ok. You are going to need a pretty good microphone to capture sound outside like that.
It has Wolfson DAC and probably a SW controllable audio chip.
This will mean that Voodoo Sound app with the recording sensitivity control will improve sound quality considerably.
let's just hope the mic hardware is of decent (phone) quality.
I just put the Amazing life THX demo as found on the Avatar Blu-ray directly onto my phone, a totally untouched m2ts file. I know my S3 wont play it, but the One plays it with MX player in software mode. its 95% smooth, just the odd stutter.
Thats impressive, very.
Edit: It seems my Nexus 10 will do as well, maybe its an A15 thing, because it doesn't work on any A9 based device ive tried it on.

Look like my version of disc does not have that demo. It was one of those promotional discs packaged with Panasonic TV's. It is still great that HTC One plays files with such high bit rate.
I think it was on the first release 2D version.

lets wait for the April batch before we call it shoddy
the One X is anything but
besides many people already confirmed receiving a flawless unit after replacing the imperfect first
Doesn't help my phone though does it and mine is a replacement. My Samsungs were all first batch, and flawless, every HTC ive had that was a launch phone has had issues with build. The One X was eventually well made, but had launch issues, so did the One S, and the One V.
The bitrate isn't particularly impressive on this file, the S3 plays stuff in the same range very smoothly for nearly all non-10 bit formats, on my Butterfly I've played an old HDDVD demo with a video bitrate of 40mb/s (H/W+ decoder). More impressive is the untouched m2ts.
I can't get the phone to play any videos other than what is recorded on it! mkv's, mp4's that work in several players i've had on the one x don't seem to run at all on this phone
It's played everything I've thrown at it so far. Currently only got the Final Fantasy films on it for now (i watch then delete.)
1080p movies have played perfectly.

Yes, I would have though either or both of MX Player and Dice Player should be able to play that file on lots of current Android devices. Can depend on exact encoding style and such like, 10-bit playback for example is still ropey regardless of device or player.

The files worked after I restarted the phone, I think I had some how made a corrupted Zoe and when I played it the video playing stopped working for everything. Hopefully this isn't a reoccurring thing!
I made a video to show my landlord how run down my building has become and upon review at home on a 4K 43" monitor/TV, I have to say that I am pretty displeased with the quality.
The video gets very fuzzy when you move the camera and things look like they are vibrating. The stabilization makes the video somewhat jerky. There are tons of compression artifacts and the overall bitrate looks very low. I checked the bitrate on my PC with MediaInfo and it shows 42.0 Mbps, which seems decent, but as you can see in the video, it barely passes as 1080p content. It doesn't look anywhere near what I expect 4K to look like. The lighting was not ideal, but it wasn't necessarily dark either.
What do you guys think?

Yeah, I know I live in a dump. I am embarrassed to have people over. The problem is that housing has become insanely expensive in the Denver metro area and it's what I can afford while still being close to work. Either way, I am going to move in February....Hopefully to Arizona where I can wear shorts year round
In regards to the video, I can tell you that the source video looks very similar. I still have it and can upload it to a file sharing site if anybody wants to compare.
Thing is the Nexus might have gotten tweaks over time while the pixel is new. We know google plans on updates to the camera. It is odd for video to look slightly out of focus though. I haven't tried a regular video of the higher resolutions, only played with the slow-mo so far.

This is very true. With only EIS they can improve the quality via software.
I took another video of my garbage dump dilapidated crackhouse building I rent a condo in with image stabilization turned off. It looks better, but still has many of the same problems, such as compression artifacts, severe loss of quality when panning, and lots of digital noise. The garage is very well lit and there really is no excuse for this poor of quality.

Here's the post I made on the Google product forums, using your video as an example:
Somebody on XDA Developers just posted a video they took outside in the sun at 4K. I think one could consider this scene to be ideal conditions. I think this is a good example of how poor the video quality is. I took a screenshot of it at 4K resolution, so you can see the original quality by zooming in if you are not on a 4K monitor.

The falling water has tons of digital noise and the entire image is blocky and covered in compression artifacts. I hope Google will address this, as I have seen better 720p quality video. This is a huge let down.
The Pixel XL is recording 4K UHD video at 42 Mbps in an h264/AVC format. I have videos encoded at the same bitrate that are near flawless. For comparison, here are 2 screenshots from some 4K showcase videos.
This video is at 38.4 Mbps, which is 3.6 Mbps or 9% lower bitrate than the Pixel XL video: http://i.imgur.com/1488tHh.jpg -- Almost no visible compression artifacts, noise, or blockiness.
This video is at 45.3 Mbps, which is 3.3 Mbps or 7.6% higher bitrate than the Pixel XL video: http://i.imgur.com/dGvl6Xv.jpg -- Again, almost no visible compression artifacts, noise, or blockiness.
Pixel XL video and the two demo videos have the same encoding profile ([email protected]), the same bit depth (8 bit), and the same chroma subsampling (4:2:0). Why is the Pixel's video substantially worse?

I'm having problems with uploading these videos to Facebook. I have the setting to allow HD uploads in high quality on in Facebook but the quality comes out horrible. I took a video at 1080p at 60fps and it looked like a video watching it at 360p

I would start a new thread, as this isn't really related to the topic of this thread.
That being said, I don't think Facebook is a very good measure for quality. Try a service like YouTube or Vimeo. They have much better quality at 1080p60 and 2160p30.
Google sounds like they are using a lot of algorithms to make better picture quality but they are probably over-processing. Maybe they should give the option to turn it off like HDR+.

Yeah it is definitely pretty disappointing. When you go indoors the quality goes down tremendously.
Here is a quick comparison I did between the Pixel XL and the Nexus 6:
Nexus 6: https://www.youtube.com/watch?v=NWhoCGFh_JA
Pixel XL: https://www.youtube.com/watch?v=W1dwmw33M98
I'm just puzzled why even the Nexus 6 does SO much better with low light for video. When it's looking at the desk the Pixel XL does fine because theres a bunch of light, but looking around the room is horrible.

Why would you record with the Pixel at 1080p60? That is why the quality is down. It had to reduce shutter speed to get those 60 frames in. Test it again at 30 FPS.

Yeah, I know I live in a dump. I am embarrassed to have people over.

That looks much better than some of the places in the Bay Area. $700k+ for a 1000 sqft run down 50 years old house with 3 tiny bed rooms.
I think the Pixel suffers in low light, but then again, what phone doesn't. It's not a high end DSLR or Mirrorless camera with an actual wide aperture professional lens. But to be honest I'm still happy.
For what it offers at the convenience of a camera in my pocket it is good enough for me. If I need to film something of high quality I'll be taking my real equipment out.
Here's my low light video test. All the details of how it was captured is available to read here: http://bit.ly/2f5z818
I bring out my DSLR when I want high quality. With the phone people just want it better or as good as last one and here it looks like they can improve a little bit on some things.
