Since the video recording is now in .mp4 format after froyo, is the quality still the same?

3gp and mp4 are containers only. The quality depends on the method of compression and the bitrate. Haven't compared them, but noticed that JPM has a bug with audio sync on HD recordings.

Hi, guys:
I just did some rtsp capabilities test on G1. Found that G1 didnt support h.264 well through rtsp, but the mpeg4 is fine. The youtube's video played on G1 looks having high quality. Can anybody confirm for me that is the youtube's video encoded by h.264 or mpeg4? And does it transferred through rtsp?
thanks.
I think it is some kind of flash-video codec, not the ones you mentioned. Adobe monopoly.
Youtube uses mpeg4 video for it's HQ streams, flv video for the LQ ones. The G1 gets served an mpeg4 stream regardless of the quality.
I downloaded some 720p video trailers and downsampled them with ffmpeg to 2Mbps and I'm happy to say they played smooth and beautifully with the stock player and mVideoPlayer. Seeking was also very quick. I did try the trailers without any downsample (they were pretty high bitrate) but they wouldn't play, so I don't know if it was a bitrate issue or something else. Next test is 720p HDMI out as soon as I receive my type D cable from Hong Kong.
how's shooting 720p videos in the dark? Do the fps go down?
shooting 720p sucks ass and looks bad, i don't recommend it. plus it shoots in mpeg4/3gp format instead of h264/mp4 which is lame.
720p playback is all great and fun, but... will it play H264 Main/High profiles? As with my current nearly-dead Touch Pro I can only play H264 baseline profiles smoothly, Main/High profiles arent supported so CorePlayer has to use software rendering, which for 480p vid does only ~8fps

You can use mpeg4 or h264 in the settings.

no it's h.263
will H.263 or Mpeg 4 produce better video? whitch one should i use for the best quality video?
From what I've read on the forum, most people would agree with you.

Dude, which one are you in agreement with?

imho, h.263 ftw. but just in case...

I use MP4 as my baseline with H.264 video codec and mpeg2 audio. My video is crystal clear.

is it possible to use h.264 without rooting?
more specific

What settings?? compression etc. (idk, anything handbrake etc. may require) for best pic?

Video: 29.9fps, 1500 bitrate, 800 x 480. Audio: Stereo output, 16 bit sample rate, 48000 hz, 256 kbps audio bitrate.
so if im unrooted should i use mpeg 4 or h.263? cant find the answer anywhere
You guys he's talking about the codec on the video camcorder itself. Mpeg4 is your best bet as its the only one that will let you select a resolution over 352 x 288.
I was wondering this about the video files on the HD: With the stock HTC firmware, the video camera records as 3GP files, which seems to be an almost willfully obtuse choice to me. But I was wondering, is this set at a hardware level, or is the camera application just part of the stock firmware? When you replace it with another firmware, would there be a way to record into a different, better quality format, such as raw MPEG - like a digital compact might do? I know I'm not quite spot on with my technical terms but I'm sure you understand what I'm trying to ask.
the container is .3gp
the video format is x264 and audio format is AAC
x264 is the standard used for HD recording and is considered the best quality format to use for video in most areas also known as AVC1 its the same codec used for bluray discs
hence you will get zero benifit from changing recording format, container format well .mp4 or even .mkv would be nice but makes little differnce i think 3gp is just limited to 1 audo + video track with no subtitles.
Right, so the format itself isn't the problem. I thought that might be the case. I just don't see the benefit of recording HD video into 3gp. It means extra software is needed for playing back recordings on your pc.
So, is there anyway, with a custom rom, to change the audio encoding? The main criticism I've seen is that the audio is needlessly low bitrate, how locked is this?

Can't help with that question, although it could be a limitation of the aac-lc audio codec (sample rate limitation)

I have some 720p MKV videos with H264 video AAC audio that I wanted to load onto my Xoom, so far I haven't been able to get it playing smoothly at 720p with mp4 H264 and AAC audio but Mpeg4 seems a little blocky.
Does anyone have any suggestions on FormatFactory (or some other mass conversion tools) settings I can use that gives me the best video quality at a good frame rate?
from how i understand it the Tegra 2 has issues playing high profile H.264, i had a notion ink adam for a week and it was the same thing on this as well.
when i get my wifi xoom ill test it but i expect the same results.
I loved my zoom but I think that's one of the most unacceptable situation for zoom. good amount of people bought zoom is for video play back. at the least, if you should be able to play anything you throw at it. I hate apple but that's one I cannot trash the ipad

I cant even move .avi to the xoom... if anyone knows how please let me know.

In Windows 7 it tells me with a lot of file extensions that they are not compatible but I ignore the message and copy them anyways. Then they play nicely on the Xoom. I've used .m4v, .mp4, .mkv, .avi.... just ignore the error message and copy the files. Then use Rock Player Lite to play.
i don't know about the format factory, i download a free version of a xoom video tool, it recommend the h.264 mp4, size: 1280*752, frame rate:30fps, bitrate:1500
The above parameters are just for your reference, sometimes, video playback quality also is based on your xoom player.
whats the name of the tool?
what is the name of the tool / free xoom conversion software you used?

In the first place, i help u find the formats that xoom support.
Audio Playback Supports: MP3, AAC, ACC+Enhanced, OGG, MIDI, AMR NB, AAC
Video Playback Supports: MPEG-4， H.264，H.263
u need to convert your mkv to mp4. i use Fox Real Xoom video converter and set the parameter is mp4, h.264, 1280*752, 1500kbps, 30fps, and i can get full screen on the xoom.
so i suggest u also set on Formatfactory according to the parameters. hopefully it can help u!

i used a free version of a tool which named xoom video converter, but there is a logo "foxreal" in the centre of the screen. at last, i took about $23 to buy a official version, now everything is ok.
