What I am trying to do, is to modify a 5 mins long divx-compressed AVI. So far, I have been able to open the file, modify it and then save it to uncompressed video (because I don't have "divx" in the available options: neither I have "Microsoft DV" like in my Premiere). Later I convert this uncompressed video to divx with Virtualdub.
However, when I save to uncompressed format, the video plays fine up to 30 seconds and then suddenly stops (the video player won't read further). Even though the rendering process seemed all ok. I tried splitting the file into many 60 sec segments, and apparently the file holds all the 30 sec correctly. If I try 120 sec instead, it's again the "no more than 30 seconds" limit.
What did I do wrong? I have a 3.0ghz processor, 1000 ram and 100+ free hd space (the uncompressed file takes about 1000 megs per minute, could it be the ram?). Please help!
