Am I going mad here? I'm using the latest version of VirtualDub with logoaway filter, all previewing very nicely. Set to full processing mode, hit F7 to save avi, and projected output file is 83Gb!!! The original avi is 1.7Gb (DivX) and I want it to remain that size after processing. Maybe I've got the Sunday block, but I give up. Can someone point me in the right direction. Cheers
