Like in title. There is option to incerase video bitrate but audio is still 48kb/s. Is there any option to increase this vaule for ex to 96kb/s like in movies taken by Nokia's?
Oh key to change video bitrate is there:
HKLM\Software\HTC\Camera\Recparam\MP4VGA\
Hi All,
I started using Handbrake to encode movies lately. Using the default settings, playback is Ok on the Nexus S albeit I think the default bit-rate is a tad too high as playback is slightly choppy.
If you use Handbrake [1], what settings did you tweak to adjust the frame rate for DVD encoding?
[1] http://handbrake.fr/
WWW.mirovideoconverter.com does a good job but can only do one at a time. You would want the nexus one preset.
As for handbrake, video bitrate should be 1500-2000, framerate same as source, two pass encoding not Turbo first pass. In audio, downmix to stereo, 48k sample rate (if master is DVD or blueray), 160+ bitrate. Advanced, uncheck cabac. Settings on top (I forgot the name), no resizing in anamorphic, auto crop, and deinterlacing slow. As for preset, I didn't use one I think. Cabac must be off or it requires more CPU to decode and causes studdering on smaller CPU devices. 48khz sampling rate for audio is important for DVD or blue ray masters or you'll lose audio/video sync the longer the video is. After encoding, rename the file extension to mp4.
This is from memory so the words might not be exact.
I was looking at the media_profile.xml file from the Xoom forums (posted and edited by bracken21, Thanks for the work) and noticed that the file was different than the Asus TF one. Instead of trying that file on my TF I modified the TF profile.
I have experienced no problems so far with this modified file but try at your own risk, replacing the file with the original should resolve any issues you might experiences, but no promises. I highly recommend backing up your own media_profile.xml instead of using my backed up original.
A few questions for anyone that knows.
For the camera app what is 'high' quality? I assume it is the 720p profile do to the outcome I had. I ask because in the media profile there is no youtube video quality but is on the app. other video quality names aren't listed in the app either.
What do the video decoder and audio decoder caps do exactly? I turned them off only because they where turned off on the Xoom, and I wanted to see if it prevented video from playing or caused glitch's (I saw no issues in the video I played)
I set the camera to the rear and "high" for quality then recorded a video before the changes and one after then transferred them to my desktop. The details in properties shows both at 37 seconds long and a frame rate of 1280x720. the data rate for the 3gp was 7478kbps while the mp4 was 20350kbps. Total bitrate increased from 7574kbps to 20446kbps. Frame rate dropped from 28fps to 24fps. file size increased to 93MB from 33.7MB. I noticed a small improvement in quality at full screen on my monitor, it was a slow video so I couldn't tell if it had more or less tearing.
more info: You will need to reboot to see any chances. setting any setting the camera can't use will result in the camera app force closing. I tried setting the frame rate to 40 in one profile and the camera app crashed every time I tried to access the rear camera (that profile was already selected so was auto loading). placing the xml with the correct framerate back into the /system/etc folder and rebooting fixed the issue.
Since it is a busy day today for me I just did some quick modifications. If anyone else wants to make a modified file with better changes (specially someone who knows audio/video better) it would probably be appreciated by all.
Placing this file where it needs to go requires root and a file browser that can mount the system folder in read/write.
The XML file should be placed in /system/etc. the full path is /system/etc/media_profiles.xml
changed:
All 3gp encoding to mp4 encoding
Rear Camera 720p quality bitrate from 8,000,000 to 25,000,000
Front Camera high quality bitrate from 4,000,000 to 8,000,000
Changed both "imageencoding quality from 90/80/70/20,000,000 to 100/99/95/250,000,000
Turned off videodecodercap and audiodecodercap
Again thank you to bracken21 for doing the Xoom's profile, which provided a base to go off of.
I'm wanting to put a few videos on for my sons, I cannot get the audio codec right, so far I've tried ac3 and aac in mp4 container with avc video, the video plays back fine but never plays audio. Tried a couple of different players (dice player just force closes) but they part without audio too. Any one know what audio codec the default video player accepts?
I can stream from my pc using plex and it works fine but would rather play from local sd card

Have you tried Mobo Player? Works fine for me and i play all types, mkv, avi, mp4
Plus they have lots of codec packages to add if havng any trouble,
Worth a try.

Thank you for the suggestion! I have been wondering the same.
I wish there was a simple way to side-load codecs onto Android so the default video player supports more

No probs.
Let me know how you get on.
Try this from modaco.
Afternoon all
As mentioned in a few threads, I've been tinkering with encoding settings in Handbrake in order to get the optimal settings for converting video. After spending a few hours with this last night and this morning - what a fun Friday night, huh? - I think I have nailed it. This profile will allow you to watch files using the native video player - you don't need anything like RockPlayer, or VPlayer. This means that they should be hardware accelerated. You can use something like RockPlayer, but framerates will suffer if you're using HD videos. I tested this using the 1080p MP4 version of Big Buck Bunny as the input file and it works very well - I'm going to give this a shot on some of my other videos today.
I have attached the profile in question.
EDIT: Rename the file to "Vega.plist" before importing (take off the .txt extension) - I've only just realised that modaco will not let me upload PLIST files...
Don't try to double click this, as it might try to open in Quicktime - no idea what it will do on a Mac! To import it open Handbrake, go to "Presets" and click "Import". The profile export feature is experimental, so I'll list the detailed settings that I used in case it does not work.
Firstly though, if you're not sure what you're doing in the "Picture" tab, have a read of this quick primer on Anamorphic video. If you want to scale down a 720p or 1080p video to match the Vega's resolution, set Anamorphic to loose, modulus to 16, and set the video width to 1024. For any videos that are not HD, or if you're not sure, just set this to "Strict": this will make sure that the video always displays in the correct aspect ratio, but you won't be able to scale the video down. Don't mess with the "Cropping" settings unless you know what you're doing.
I'd highly recommend scaling 720p or 1080p HD videos down to match the Vega's resolution - it drastically reduces the output size:
The original version of Big Buck Bunny (1920*1080): 885MB
Strict anamorphic - no scaling (1920*1080): 388MB
Scaled down to 1024*576 with loose anamorphic: 128MB
The Vega will play 720 or 1080 files, but you won't see that extra detail so there's no point in wasting the extra space on your SD card, IMO.
Detailed settings - in case the attachment fails. If anyone finds any optimisations for this, please let me know!

Audio Tab:
This is going to vary, depending on the audio tracks in the source video (for example, a DVD may have multiple languages and each of these will be a different audio track) - I have not yet tested multiple audio channels on the Vega, so I highly recommend only adding one audio track to your output file. The following drop-downs must be set:
Audio Codec: AAC (faac)
Mixdown: Stereo (no point having multi-channel audio if you can't play it on the Vega)
Samplerate: Auto
Bitrate: 160
Subtitles:
This will depend entirely on whether you want to include the subtitles from the source video. This can get a bit more complicated, so I'm not going to cover it here; if your source has subtitles as a separate track (i.e., soft subs not hard subs), you may need to take some extra steps - do some research on this over at afterdawn.com or doom9.org.
Chapters:
If your source video has chapters - like a DVD - you can replicate those chapters in the output video; if there are no chapter markers in the source, the checkbox is greyed out.
Advanced:
There's quite a lot in here, so bear with me...

For those that are interested in the more nerdy side, I started off by copying Handbrake's built in "High Profile" x264 settings. I found this page, which mentions that the Xoom only supports the baseline x264 profile, so I turned off the advanced x264 stuff. However I realised that even though the hardware is the same, the Xoom is not the Vega. So started re-enabling the advanced options one by one to see if any caused a problem. The only one I found that caused any issue was weighted P-Frames, which seemed to make videos judder slightly.

Cheers but I shouldn't have to convert for my Optimus 3D as well as the Vega, one video should be able to work on both

I have installed various 3rd party camera apps & despite increasing video recording bitrate in app settings, recorded videos all have 40mbps bitrate.
Can the media profiles xml be edited just like with older phones?
Has anyone else tried or had success with increasing the bitrate for video recording? Any input would be appreciated
Edit: found media_profiles in system\vendor\etc...going to change it and see what happens
