video file is restricted by length of movie not file size i have burned a 1GB file onto a 700MB/80min disc as the movie went for just under 80mins long. see www.vcdhelp.com its full of great stuff, and heaps of help.

The technical answer is this - the 650 MB size on a CD-ROM is not the true size of the disc. It is the size of data writable under CD-ROM standards, which use parts of the disc for error correction and redundancy. VCD/SVCD do not use this error correction and use a different file system format from CD-ROM, so more of the disc is available to write to. I don't know the exact count, by typically you can get about 800 MB roughly of VCD/SVCD video on a 650 MB CD-R.

VCD and SVCD are mixed mode CDs. They use mode 2 form 2 for the video data. Mode 2 form 2 allows for 2324 bytes of data per sector (as opposed to 2048 for mode 1 and mode 2 form 1). The mode 2 form 2 CDR has about 13½% more capacity than a normal data CD-ROM, or about 738 MB for 74 minute or 797 MB for 80 minute.
