File size question?

[ericd]

ok, i had an avi file(part1 of 2) that was 157mg, i encoded to vcd and after conversion the file was 651mg.i can fit that on cdrom.then i did the full movie,the matrix.the starting out avi is only 101mg,when i converted it,it was 1.3gigs. i used the same templates for both movies.the avi matrix is the full movie but i just don't know why the vcd came out so big?thanks for any input

Hi,

The problems is that VCD uses i set bitrate. so if the matrix avi file had a way lower bitrate, but a longer running time, you would end up with a bigger file. This is because VCD is 10mb per minute. No more, no less. while a (DivX) avi file can be (at lower bitrates) like 2 hours in 100Mb while another avi (With a much higher bitrate) is 10 minutes in that same 100Mb.

Hope this explains it for you.

thanks for the explanation. I guess the best thing for me to do then when i get a full movie in 1 file is to convert to vcd first,then spit to however many cdrom i would need.thanks

For the standard VCD 1min=10MB, a 74min CDR holds 740MB of data, and an 80min CDR will hold 800MB.

Use the standard VCD template to make a big file and then cut it, OR just encode part of the film to start with, I don't like cutting

Also you can make an xVCD. Look at the bitrate calculators under tools (links on left) and enter the movie run time, number of CDRs, etc and it'll give you a bitrate to make your movie fit on that number of CDRs. You have to use 2pass VBR or CBR to encode thou.

Often you can increase the bitrate above teh standard 1150kps and get a better quaility movie. For example, if I put a 120min on 2 80min CDRs I could up the bitrate to 1564kps.
