AVI/DivX --> DivX (different bitrate)

[brendt]

I am using VirtualDub 1.5.10 and the Divx codec 5.1.1

I am having trouble converting a file to a new bitrate (in hopes of reducing its size). I'm not looking for anything major -- just like (for example) 90-100 minutes of 320x240 on one 80-minute disc. Even if I set ridiculously low bitrates, the resulting file is only slightly smaller. All the tutorials that I could find on here are for earlier versions of the codec, and so the configuration screens that I have look nothing like the tutorial, and I can't seem to "map" the changes over. Not even sure what to ask beyond this.

HELP!!!!!!!!!

Well, many DivX's I've seen are like 640x350, 120 min+, and look OK, so it's not impossible. What's your source (audio bitrate/codec, video bit rate codec)?

Usual source is from a capture card:

Video - 352x240 - 768 kbps (DivX 5.1.1)
Audio - Mono WAV file (haven't been able to get audio compression working)

Generates a file that is about 665 MB for an hour of video. I'd just as soon leave these settings alone and then convert as need be. The conversion is what I am having trouble with.

OK, let me count: 90 minutes, 768 kbps gets me to around 520 MB. That's video. But a wav file takes an amazing amount of space! Encode it to MP3 or something at 128 kbps, and you'll end with 520+86 MB - Well within the "one CD" range... It's the wav audio that's filling up your file - not the video.

Duh -- silly me -- I bet you are right. I will test this later today.

Thanks for showing me the forest around the trees.

That was, indeed, it. Man, I feel stupid.

Thanks again.

Glad you fixed it!
