I'm starting to deal with Digital Video much more, what with video from my camera, MythTV, my DVD collection, and my Cowon D2. Here are my notes on codecs, conversions, and the like.
Cowon D2
The D2 plays the following video format:
AVI - [[Xvi D]] - 320x240 - 30 fps - VBR 50 MP3 - 128 kbps
Windows Media Player does not have the XviD codec by default, so you need to install it separately.
ffmpeg settings:
ffmpeg -i INPUT -s 320x240 -vcodec mpeg4 -vtag XVID -b 500kb -mbd rd -flags +4mv+trell+aic -cmp 2 -subcmp 2 -g 300 -r 29.97 -acodec mp3 -ab 128 -ac 2 -async 1 OUTPUT.avi
ffmpeg -i INPUT -pass 1 -s 320x240 -vcodec mpeg4 -vtag XVID -b 500kb -mbd rd -flags +4mv+trell+aic -cmp 2 -subcmp 2 -g 300 -acodec copy null.avi -threads 2 ffmpeg -i INPUT -pass 2 -s 320x240 -vcodec mpeg4 -vtag XVID -b 500kb -mbd rd -flags +4mv+trell+aic -cmp 2 -subcmp 2 -g 300 -acodec mp3 -ab 128 -ac 2 -async 1 OUTPUT.avi -threads 2
(You can use 320x180 plus -padtop 30 and -padbottom 30 for 16:9 aspect ratio content. For mid-quality bitrates, use 350; for low-quality, use 250.)
Handbrake
I use a Handbrake script to rip movies directly to Cowon format. I'm considering playing with other parameters.
VLC
You can use VLC to rip video.
Panasonic Lumix DMC-ZS3
VLC plays AVCHD (.MTS files) just fine. To convert it to AVI, I use ffmpeg. First, I figure out the bitrate of the original file:
ffmpeg -i file.mts
Then I convert using the bitrate information. It's important to do this; otherwise, the converted file will be pixelated:
ffmpeg -i file.mts -b BBBBBk file.avi
where BBBBB is the bitrate in kbits/sec.
