I know some things about audio and audio compressing, but i'm quite new to the video editing. I am trying to make some simple video clips for my band. We recorded a song, i ripped it to mp3 (for the sake of getting a small video i can put on yutube i ripped it to 128 kbps). I recorded a video with my photo camera. It is 4:31 minutes and 83,4 MB. Then i disabled the sound of it with Stream List in Virtual Dub Mod 1.5 and i put the band song in it as an audio stream (the mp3 is 4,63 MB). When i saved the file it took like 1,5 hours to process it and the result is a file of 547 MB. How is this possible and what did i do wrong? I don't remember which compression mode i used but i put it on 80% quality i think. Movies of 2 hours with reasonable good quality are usually 700 mb. So how can this 4:31 minutes video be 547 MB?
Maybe you used a lossless codec or even saved it as uncompressed? That might explain it, try compressing to another codec like xvid. If that still gives you a huge file, disable the audio and see if it has any effect on the size.
In the list of possible codecs i don't have xvid, where can i get a good one? Also, what is the difference between xvid and divx? That last one i do have, it says DivX 6.8.5 Code (2 Logical CPUs), does that mean i need a processor with two cpus? Dual core i mean.
