[Q] Best Video Quality on Nexus 7? Bitrate, etc - Nexus 7 Q&A, Help & Troubleshooting

I'm trying to ensure I use the maximum quality video, without using unnecessary space. I'm using AVS Video Converter. What's the maximum video bit rate, frame rate, Audio sample rate (IE 48000 Hz) and sample size (IE 16-bit), and Audio bit rate for the nexus 7?

bump

Generally, I use CRF 16-18 for any videos. Use x264, or if you don't like command line tools, handbrake, its got a really easy UI. File size and bitrate, of course, are going to vary with content, but quality should be the same for everything.
I don't pay much attention to audio, but I try to get FLAC.

What video encoder do you guys recommend?

Prefer something that is fast and easy to set? It seems even with coreplayer there are some codecs such as sorenson that still can't be handle by the player, would love to have a nice video encoder to do the job for the odd video that doesnt play on hd2.
Thanks!
im using TMPGENC EXPRESS 4.0 .
quality is very good
i have opened a video performance thread in LEO-LEO forum. please check. thanks.
I'm trying different codecs to see which would be better to use.
So far I'm using the mpeg4 standard (MPEG-4 AVC/AAC/MP4), and it works almost flawlessly when using a bit rate of about 3000kbps at 30 FPS (800x480). The videos taken using the Camera are also encoded with mpeg4.
Oh, and I'm using the HTC video player. CorePlayer's performance for the HD2 using either GDI or the raw buffer makes me cringe (and it somehow reduces colors, not sure why; compare HTC's promotional video played in the Album and in CorePlayer).
I'm encoding with MediaCoder, which is free but isn't exactly what I'd call user-friendly.
EDIT: And the performance is even better in Windows Media Player itself.
What the hell, everything's upside-down.

I find it to be so (I had much less frame skips in WMP). Then again, it might depend on the video.
Try Media Coder its free and works really well.

It knows about Nvidia's CUDA . It's the best !!!
I use Handbrake:

The latest version works very well - choose the iphone/ipod touch preset and increase the resolution from the puny 480x320 that the iphone can handle.

Seeing as this thread has come back to life anyway: the Video Encoding GUI does a very good job of converting for a Touch HD, TP2 or TD2, but it has a maximum bit-rate of 1000kb/s, which is really not high enough for an HD2. (On lesser phones if you make the bit-rate any higher you lose smoothness of playback, but on an HD2 you don't have to make that trade-off). MP4ForHD has the same problem. It'd be nice if the author of either of those could do an HD2 version.
So, I'm not sure we've actually come to any useful conclusions in this thread. As I have an HD2 arriving tomorrow, I'm quite keen to start converting some videos for it.
What I need is:
For an original video that is <= 800x480, the resolution should remain unchanged. For a video > 800x480 it should be downscaled to fit within 800x480 with an unchanged aspect ratio. (So, for example, a 512x384 capture should be output as 512x384; 640x360 should be output as 640x360; 1280x720 should be output as 800x450. No cropping under any circumstances.)
The output frame-rate should always be the same as that of the original clip.
The output audio should have the same volume and same sampling rate as the input audio. If the input audio is > 2 channels, it should be downmixed to stereo.
It needs to support container and codec options that are optimised for playback on the HD2 using either HTCAlbum or WMP. (Not sure yet which of these will be best, and am still researching encoding options in other threads!)
The output bitrate should be appropriately reduced for lower-resolution clips automatically.
All of the above needs to be something that is retained from session to session so that you can simply point it to the input file and click "Start" without having to reselect options each time.
It needs to be able to queue up multiple files and process them one at a time.
Good output quality and smoothness of playback is obviously important.
Something that does the encoding quickly rather than slowly is a plus (but I'm stuck using a creaky old 3GHz Pentium IV with on-board GPU at the moment, so am not expecting miracles).
It should be able to handle 720p .mkv files with ac3 audio, and also lower-resolution xvid files.
Freeware would be a big plus.
I've checked out a few of the suggested applications (not all) and most of them seem to lacking at least some of this. Things like Video Encoder GUI or MP4ForHD do an excellent job for lower-spec phones, but the bit-rates are capped at a level that is far too low for optimum performance on the HD2. Some of the more sophisticated applications have some surprising omissions, such as not being able to store settings between sessions, or not being able to specify 800x450 as an output resolution, or not being able to specify 800x480 as a maximum resolution and have it choose the actual output res depending on the input res, or having no option to keep the original frame-rate or the original audio sampling rate, or bit-rate.
There must surely be something out there that covers all this?

Strangely enough, for me the HD settings on MP4ForHD for encoding did quite a good job of 300 and A Scanner Darkly. Smooth playback and an acceptable quality for a DVD rip. The only issue I faced was a bit of an audio sync issue with 300. The output sizes were approximately 600-700mb
If there could be better output or an easy way to ensure the audio syncs with the video properly, the HD2 would be golden. (I am stuck on a 3 year old laptop which has had some minor processor/hdd/ram upgrade and took 4 hours to encode a DVD for my HD2.

Maybe going further above bitrate wise is just a waste of space and that 2 pass encoding at such bitrates from both converters just means optimal output.

That is a perfectly valid opinion, but (having done some viewing of the output on a PC screen) it is not one that I happen to share. (Not for downscaled hi-def material, anyway).

I have tested, and for sure that downscaling HD media to a 800x480 screen requires more than 1000kbps to bring out the details.
Are you saying I can install new codecs and be able to record video with them? At the moment I use MPEG at 640x480...I can get better resolution?

Movie Converters and Settings?

Hello,
Can this HD2 actually display real good video clips?
I have tried a load of converters and played about with various settings but all video looks average at best and most are jerky.
Anybody got some tips for converting great looking video to show off this screen?
Any tips appreciated.

Try 'Mp4forHD'- just google search and it should be the first link.
Works like a treat and plays via HTC albums.
Thanks for the reply
I will check them out.
HDencoder (you can get it here on xda-dev)
Originally designed for Touch HD, but still working outstanding.
The encoder is the same than MP4forHD, but the GUI is more simple.
Set bitrate to custom and encode with 1000kbit @ 800x480 for 720p or 1080p videos.
HD2 is capable of higher bitrates but HDencoder only support 1000kBit max...and the difference to higher bitrates is not really visible. Higher Bitrates causes only much bigger files and more battery drain....

Yes it can play back very high quality video perfectly. I have transcoded a 720p movie file down to the HD2's native resolution (800x480) and its looks absolutley stunning. Its fun to show your iPhone friends and watch their faces as they see just how stunning the screen looks displaying a proper native resolution image taken from a higher resoluution source... Simply stunning.
Thanks again for the replies!
I am can see some stunning video now.
Cheers.

Is this a different encoder from HTC Touch video converter 1.21?.......the bitrate can only be set to 999 max on this program.
I can't seem to find a program called HDencoder.

I strongly disagree. MP4ForHD will go up to 1600kb/s and the improvement in visual quality between that and something encoded at 1000kb/s is (to my eyes) dramatic, not subtle. If you watch some of the videos from this post (encoded at 2000kb/s and using CABAC) that's another quite visible step up in quality. Beyond 2000kb/s the benefits start to become a bit more ambiguous.
(The above assumes a good-quality, high-definition source, of course - lower bit-rates are quite adequate if you're converting something with <800x480 res, but your average xvid dvd rip plays quite happily in CorePlayer anyway, so there would be no need to convert it).

Encoding MKV....always get lip sync problems?

I have tried loads of converters and can get GOOD quality videos if i like with no lip sync problems but i want EXCELLENT quality video like the encodes i had for my HD2 but just can't find a stable converter which works all the time.
The best video quality i can get is by using....
Winmenc then DVD Catalyst 3 then Any dvd Converter.
I can get stunning video from Winmenc but some clips either dont display the picture on the phone or have lipsync problems.
DVD Catalyst comes a close second for video quality and all clips play but still get lip sync problems.
Any dvd converter gives good quality video with no lip sync problems but picture is nowhere as good as Winmenc.
Anybody got any custom profiles or programs to get excellent quality video with no lip sync problems?
Thanks for any help

Double Twist
Why don't you try to use DoubleTwist?
It looks like iTunes, and when you sync any type of movie or audio with Desire, it will convert to the format that Desire can play. Just like that, no need to configure anything.
It also run quite fast, and it's free!

Winmenc i think still has much better picture quality but lip sync is way out, especially if you fast forward or back....

And MP4forHD looks great and plays fine when i set audio delay to 0.3.

Sorry for the late reply, here are the megaupload links to a couple of video clips i've encoded using the preset i posted yesterday. Souce was a 1080p BRrip in both cases.
http://www.megaupload.com/?d=V8TPXP3T
http://www.megaupload.com/?d=3V318NMP
The Transformers' souce had a subtitle track and it was embedded in the rip, so that answers the previous question about subs. I have yet to check if subtitles can be disabled, but i guess it can be done (in my case, i am interested in plain english audio tracks, i don't even know what language is that )
edit: for some weird reasons the audio is noticeably out of sync WHEN PLAYED ON A PC...they are perfect on the Desire though. Pretty weird, last time i checked my pc kicks asses so the problem must be resting in the mp4 container..

I'll upload the profile for you when I get back on the PC (by weekend). I change some things around with every vid though, depending on its properties. Too many internal coder settings you can tweak for slight visual/acoustic differences including how much to raise the sound in db and how much of the clip to cut out.

Ok Thanks
Just to quickly add - I don't tend to use automated profiles although I know it's what most are after (quickest).
What do you think of YouTube HD? Good enough quality for you or, you'd like better?
I had a quick look at your upload vid properties and they have different internal recode settings and different end file sizes. As such, a true cross-comparison is very difficult (all things kept consistent, the stream with the highest bit-rate and file size will have better visuals). The point of transcoding really is to keep the file size as small as possible with video and audio at your accepted levels -- that level differs for everyone depending on a variety if factors. Many YouTube HD vids are for instance only 480-560 Kbps streams. But all things which impact quality were not automatically kept fixed in these transcodes. Your vids were;
1) Any
Duration : 2mn 1s
Overall bit rate : 2,091 Kbps
Video
Format profile : [email protected]
Format settings, ReFrames : 2 frames
Bit rate mode : Variable
Bit rate : 1,865 Kbps
Width : 800 pixels
Height : 480 pixels
Frame rate : 25.000 fps
Bits/(Pixel*Frame) : 0.194
Stream size : 27.1 MiB (89%)
2) MP4
Duration : 2mn 1s
Overall bit rate : 1,994 Kbps
Video
Format profile : [email protected]
Format settings, ReFrames : 1 frame
Bit rate mode : Variable
Bit rate : 1,544 Kbps
Maximum bit rate : 2,932 Kbps
Width : 800 pixels
Height : 448 pixels
Frame rate : 25.000 fps
Bits/(Pixel*Frame) : 0.172
Stream size : 27.0 MiB (93%)
3) Winmec
Duration : 2mn 1s
Overall bit rate : 2,713 Kbps
(missing vital info it would not show here)
Bit rate mode : Variable
Bit rate : 2,579 Kbps
Width : 800 pixels
Height : 480 pixels
Frame rate : 25.000 fps
Bits/(Pixel*Frame) : 0.269
Stream size : 37.4 MiB (95%)
So the Winmec transcode should have much better visuals than the other two here, even just looking at the empirical data, however, how much of that better-ness is perceptible to untrained and trained human eyes? Judging by mass-accepted online "HD" video, usually not much - and on portable phones - even less (perceptible difference threshold decreases with decreasing display size).
I'll upload a few transcodes using different settings... see which you feel is better (on the intended phone).
-------------------------------------
- Sent via my HTC Desire -
Thanks for the info.
Another update:
Looks like your A/V sync issues are caused by too high bit-rate video streams being too power demanding on the hardware of the phone and so the CPU can't keep up. While running some test encodes for the post I had promised, upon checking playback on the Desire, I noticed getting the same A/V sync problems which don't exist on the Desktop. Dropping the video bit-rate alleviated that problem completely albeit the visual quality dropped too. I better check the vids in the default player too just to be sure now (I use Act 1 or Meridian video players mainly). So do keep in mind that higher bit-rate video playback requires more hardware power and hence much higher battery usage than lower bit-rate.
At the moment, I'm stuck with the latest update I've just installed for Super(c) not changing internal codec settings no matter what options I choose (same Lady Gaga 1080p video taken from a Blu-ray rip). Very strange. Just working on getting that running before posting some transcodes. Bear with me, please...

Best bitrate to filesize ratio for movies

I have a few favorite movies at 1080p over 10mbps and I would like to store some of them to the SGS, Im wondering whats the best bitrate to use to keep the video's pretty great while having a very acceptable file size.. Im using handbreak to convert
If you're only intending to watch them on the phone's display then you only need to encode them at 800x448 (for widescreen ratio).
If using this resolution with a video codec like MPEG-4 ASP (ie DivX) then 1000kbps is probably a good minimum. Maybe 800kbps minimum for MPEG-4 AVC (ie h.264). Depends on content of course. These figures are for "average" bitrates and assume VBR. If CBR then increase this by 50-100%.
I think you should use own Samsung's promo videos as reference.
All of them that I have here looks absolutelly gorgeous on the screen and they all range 4500 kbps in average.
Ive been using dvdfab to rip movies at 800x480 with about a 800kbps bit rate. They look the bomb. 2 hour movie about 800mb. I have to use the 128kbps audio option other wise I get sync issues.

[Q] Best resolution and codecs for video playback?

Hi guys,
I'm curious how to encode a video for playback on SG3 to achieve best visual and audio output and keep the lowest battery consumption. So, what do you recommend:
Video:
resolution
codec
fps
bit rate
etc
Audio:
codec
sample rate
bit rate
CBR / VBR
etc
SG3 display resolution is 240x400 but I found on official samsung site that (best or recommended or ?) resolution for playback is 720x480.
Thx for any advice
Resolution/codec/bitrate: SD (720x480 or less)
- if you download an XVID film or series (and the size doesn't matter) you can directly play it from inbuilt media player.
Audio: I suggest MP3 CBR 320kpbs, or MP4A VBR at highest quality, MP4 produces better quality and supported by most popular media players.
Codec:
xvid - good quality, and less CPU usage
h264 - good quality, smaller size, but more cpu usage.
FPS: use the source values (if your movie is 25fps and want to convert to reduce size etc. use 25 fps)
Bit-rate: depends on SD-card speed, most of XVID movies are @1000 kbps, maximally use 1500 kbps I think it's enough.
Sample Rate: 44100 Hz is standard CD quality, 48000 Hz is DVD quality, I think you will not hear any difference.
