> 1 second of MPEG-1 video+audio will be around 150KB (180?) (1.5Mbits/s) (give or take). I thought it was about 300k? (double speed CD-ROM). -MaRiO- -= Intel inside! (…my washing machine) =- Confucius say: "A bird in hand makes it hard to blow nose"

Gday, >> I thought it was about 300k? (double speed CD-ROM). No. If it was 300K you would only get about 36 min. on a CD (650MB/300K = 36 min.) (Video-CD's hold 72 min.) Sam Yates Montrose, Victoria, Australia. samyates@werple.apana.org.au

Yes, you're right about that. But doesn't the amount of data depend on the amount of moving pic's in the video-data? (e.g. newsreader=stable background, not much data. Actionmovie=no stable background, much data)? -MaRiO- -= Intel inside! (…my washing machine) =- Confucius say: "A bird in hand makes it hard to blow nose"
