I've been encoded some divx movies in virtualdub at very low bit rates to run on a pocketpc phone.(O2 XDA). I get reasonable results using codec 4.12/dual pass/bit rate=200.
Im trying the 2d cleaner filter to remove some of the compression artifacts and have has some success.
My question is a general one and I should say that I've only just started using virtual dub - very good program BTW.
I currently create a uncompressed avi using flask ( both sound and video). This is loaded into virtual dub. I use a rotate filter and then compress to a divx output file.
When do I use the 2D filter ? If I simply add in the 2Dfilter after the rotate filter then am I not simply just filtering the input from the uncompressed AVI ( which has no compress artifacts ).
I've also tried loading in the resultant divx avi into virtualdub again and running the 2D filter on it's own but I then have to dual pass compress the already divx compressed file again. Am I not then trying to divx compress an already compressed file.
Any ideas ? I think I'm missing something very basic here....
