this relates back to a previous post (http://forum.doom9.org/showthread.php?threadid=52806&highlight=conspiracy), but I've discovered some things since that change the issue somewhat.
Basically I have some old Xvid encodes that look great when played back when I have the original codec used (Nic's Nov. 2002 build I think), but look like crap on any builds of his past sometime around spring or anyone else's build (Koepi, Umaniac). I originally tried ffdshow to workaround the problem, but after much testing it doesn't seem to be helping. Then I tried using Koepi's build (since the errors are more noticeable with it) and then looking at the videoclip frame by frame through Virtualdub and it still looks just as bad (bleeding colors/pixels, extreme degradation between keyframes, etc.). Is there any way to get this to look right? In ffdshow I've tried different postprocessing methods, having the IDTC method set as Xvid, having it autodetect workaround encoder bugs, it doesn't seem to make much difference.
If anyone has ideas, I'm interested. If not, maybe there's another question you can answer. For a while I was using a more recent build of Nic's that didn't make the old encodes look bad, but now going back, I'm finding that the stuff I endcoded with that looks fine on other builds like Koepi's, etc. Is there some sort of analysis program that can tell me what build these were encoded in? This seems like the best solution at the moment; sticking with a build I can watch my older encodes on, but whose encodes will be compatible with current builds. (sorry if that's confusing, I'll try and clarify if I have to). I would find out myself, but I've lost the file since then and have done a clean install of Windows, so really I have no clue. If there's no way to determine it, is there some website that has an archive of Nic's previous stable builds? I might be able to figure it out from experimenting.
Thanks in advance for whatever help I get, I'm sure this can go a couple ways.
