I have downloaded virtualdub and have edited a 24 min mpeg. I have made it 6 min and saved it as an avi file. When it was finished I looked at the file size and it was 3.15 gb. I was expecting it to be under 100mb how has it done and what do I do to make it smaller?
You’ve not selected any compression with a codec like Xvid or Divx.
It’s the video tab at the top & select “compression”. A list of valid codecs will appear, select either Divx or Xvid & then confgure & set a bit rate of around 1200.
There is an option for Direct Stream Copy where no recompression takes place but I don’t know if that applies to edited video.
