VDub Compression Issue

[EleventhAkatsuki]

All right, I'm trying to compress this video in Vdub, right? So I go to compress it with XVid, because I notice you can edit it so that you can say what the target size is (cuz I want to compress my video to below 1 GB). So I enter the number of MB's and stuff, and save, and it does it's job... and then I check out the video and some parts are just completely blacked out, for just the video, not audio. Is it doing this just to keep my video size low, or is there some other problem? And how can I fix it? And is there an easier way to do this compressing thing than what I'm trying?

You know, there are better codecs if you're willing to go up to 1GB that are lossless or almost lossless.

A full AMV with XviD for the average of a 3 minute song should be under 100MB, even you have complex effects. Complex effects WOULD account for the black areas, but only if you had a bitrate that couldn't handle those areas. So, essentially, if you're willing to go up to almost 1GB, use something else besides XviD. You only need it for a distro version, and then we can talk about configuration, or you could use x264.

One: my video is approx. 8 minutes long.

Two: I discovered that the problem began not when converting the video, but when I rendered the video from Vegas (and thusly a .veg file) to .avi. As far as I can tell, the blacked out areas are those in which I used velocity effects. Help?

you weren't using divx or xvid footage...were you?
if so, transcode your footage/clips with a lossless codec

and I'd recommend x.264 (for my blue trailer, the x.264 version is half the size of the xvid version...looks better too imo)

Vegas won't even let me put xVid into it. All my video files got changed to lagarith lossless.

check the settings you have enabled for lagarith
null frames may cause issues in editing programs
check to make sure "always suggest rgb for output" is checked
