Pete, Thanks for the info. My conversion is from 720x576 pixels x 25 fps to 352x240 x 29.97 fps. Audio is also resampled from 48kbs to 5 channels to 44kbs, I don't know how many channels, probably 2. I don't know what you mean by bitrate. Is this just a multiplication of the pixels x color depth x frame rate, or does it have something to do with the quality of conversion? So 4 frames per second is not unreasonable to a MPEG-4 VCD for a 320x240x30 resolution on a dual Celeron 366MHz using the DIVX encoder. IIRC a 1.2G Tbird does this at 18-24 fps depending on FSB/memory setup. I am not sure if that's what I am doing. I am doing VCD, but from something I read, I don't think it is MPEG-4. I think it is fairly primitive, only MPEG-1. From what I can see, this experiment is going nowhere, since I am now at 370 MB output size, and not yet in the middle of the movie. It will not fit on the CD. I will have to figure out something with the sound, since I may be carrying over more channels than I need. Also, there is soething called SVCD, which has a variable bit rate, with higher quality, but may result in lower output size because of variable bit rate. VCD has a fixed bit rate, which must mean a very primitive compression scheme. It also looks at the preview that there is a black frame around the picture, which I will try to get rid of. Joe
