Digital Video
From Eugene Eric Kim
I'm starting to deal with Digital Video much more, what with video from my camera, Myth T V, 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.
