More iPod video details revealed
Found this on Apple’s site:
“iPod can play the following video formats:
File formats: .m4v, .mp4 and .mov
Video: Up to 768 Kbps, 320 x 240 pixels, 30 frames per second, Baseline Profile up to Level 1.3
Audio: AAC-LC up to 160 Kbps, 48 KHz, stereo audio
File formats: .m4v, .mp4 and .mov
Video: Up to 2.5 Mbps, 480 x 480 pixels, 30 frames per second, Simple Profile
Audio: AAC-LC up to 160 Kbps, 48 KHz, stereo audio”
So video will have to be converted to play. That’s unfortunate, and will, I think, limit the hack appeal of the video features. And I don’t see how it can jibe with what Cringely says about HD - 480×480 isn’t even full-on SD NTSC resolution (that’s 720×480). And it’s sure weird that it doesn’t play MP3 audio.
Got to see about using transcode/ffmpeg/mencoder to do this automagically.

it appears that ffmpegx version “v0.0.9t r3″ doesnt do baseline h.264 by default - the video that it created doesn’t go onto my video ipod, but it seems to have all the right settings.
I’m still looking how to control ffmpeg profile settings.
It’s been quite difficult for me to figure out how to export mpeg1/mpeg2 to H.264 - MPEG Stream clip gives me out of sync A/V, and QuickTime Pro 7 won’t touch the MP2 audio. Not to mention the QT7 H.264 re-encode is SLOW AS HELL on my Powerbook G4/1.67
