Fitting Xvid on one cd!

[gq4life]

Is there anyway to fit an xvid movie (usually around 700mb) onto a 700mb disc? I have been using virtualdub to save the wav and then use tmepgnc to encode the xvid and the wav audio together. It is always way way too big to fit onto one cd. Using 2 cd's for a movie seems like a pain in the rear. If it is not possible, can somone please tell me what they think is the easiest to way to cut the one movie into 2 parts and cds?
Thanks

gql4life,

Short Aswer:
Use a lower bitrate.

Long Answer:
I'm going to assume that you are using a bitrate calculator? What's going on is that the xvid codec uses a multibitrate encoding process. It basically changes the bitrate on the go while trying to stay within the bitrate that you specified. This can make your file larger or smaller than you expected. The DivX codec had the same problem, until they gave it multipass capability. The first pass analyzes the video and set where in the video to use the most bits and where to use the least bits. The second pass is where the actual encoding takes place. The video you end up with is almost the exact size you are expexting. In time xvid will have multipass, but until then, use a lower bitrate.

Hope This Helps,

I just checked that xvid does have 2-pass encoding. I'm seriously embarrased.

I kinda get what your saying but not really its all good. How would i use a lower bitrate in tmpgnc? can you tell me which menu I go into and what tab i select? Sorry for not knowing anything.
Thanks

Your subject line says "Fitting Xvid on one cd", and that is what Epi is trying to help you to do. I get the impression since you are using TMPGEnc that in fact you are trying to fit an Mpeg (in VCD format) on to one CD. Is that correct? If so, then here's a guide to fitting a whole movie on one CD: https://www.videohelp.com/forum/userguides/84759.php

I hope it's appropriate to ask on this thread. I just wanted to get some clarification on bitrates. I have a 45 minute xvid avi file (640x352, 29.97fps) where the video portion is about 200 MB. Using my calculator (and the xvid bitrate calculator) I figure that the bitrate is about 615 kbit/sec.

This file looks great on windows media player. But I thought a 615 kbit/s bitrate would suck. Did I do the calculations incorrectly?

Also, given that the bitrate is 615, if I encode this using tmpgenc to make a vcd or svcd, does that mean it wouldn't be worthwhile to set the bitrate on the encode to much higher than 615?

Thanks much!

Source bitrate and dest bitrate are in no way related, specially when you're going from mpeg4 to mpeg1/2...
