scvd file to large

[muskie]

I have a copy of Harry Potter (avi format) in two parts. I encoded it with TMPG. to scvd on part one. The file was so large it would not fit on one cdr. I am using a 80min. cdr, the half I encoded way only 74:34 m/s. I knew the file would be a little larger but it went over 90 mins. long. Is this normal or could there have been a glitch in the encoding. Thanks

So what was 74:34 and what was 90 minutes???
Creating a normal SVCD file will get your 40 minutes on 1x80 minute CD-R. In VCD quality you should get 79+ minutes of video on 1x80 minute CD-R.

Filesize is determined by the number of bits per sec x the number of seconds. In short, your filesize is determined by what bitrate setting you use. You should not arbitrarily start encoding to mpeg2 at random bitrate settings. Download a bitrate calculator from the tools section and determine the exact bitrate to use to fit x amount movie onto x amount cdrs. Note that bitrate calculators only work when you encode in 2-pass vbr or cbr.

unclebud you can fit a heck of a lot more onto an 80 min cdr than that. Its possible to get upto 60-65 mins of high quality video onto an 80 min cdr. I know you are talking about using cbr 2.5mbits to fit 40 mins onto each cdr but I consider that far from normal. I think most people take advantage of the vbr and fit at least 50-55mins per disk.

Thank you both very much, I never even thought about bitrate.
