the most common video format on the web (esp on torrents sites) is one with an avi container and xvid+mp3 codecs. it should run on about anything, since it is pretty much the standard... in case you're looking for free/open codecs, use oggtheora+ogg in a ogg/ogm container - good players such as VLC and MPlayer will play them in whatever platform you're running, just put the link for them. people will thank you for that, btw.
the hint, though, is paying attention to the bpp (bits per pixel) of your video when encoding. look at this mplayer link (http://www.mplayerhq.hu/DOCS/tech/encoding-tips.txt) for nice tips on that, but to sum up: i've recently uploaded a series of videos to my recently created site (http://qazav.wordpress.com/) and i wanted a good size/encoding proportion. i realized videos with 0,20 bpp for internet are very ok for watching, even when people resize it to full screen, and tend to be small. the parameters i used were: video: codec: xvid (pixel format yuv420p) medium kbps: 500 VBR (for a 0,20 bpp) size: 352x240 NTSC (crop black bars if needed) quantizer limiters: min 2, max 6 fps: 24 or 23,98 audio: codec: mp3 frequency: 44100 bitrate: 92 kbps aditional hints would be: use 2-pass encoding; studying GOP-size and P B I frames should help a lot when coming to a very nice encoding, but i myself can't help you in this particular field. hope it helps, flavio _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
