Wow, I've been very frustrated today. I've gone from Premiere crashing because of low memory to it not working at all. While trying to resolve the memory issue I installed a few codecs/programs and ended up uninstalling them, that's when Premiere stopped working altogether with my avs files. I am trying to load two different type of files (basically just trying to see if one will work over the other) and getting the same error with both. I'm using the directshowsource script for an .ogm import and a MPEG2Source script for editing directly with vob files (which is how I normally edit). But now I'm getting these errors. I'm using Premiere Pro (Pro 1.0/Premiere 7.0)
"Premiere AVS Plugin Error
Avisynth configuration error or old Avisynth version. Please do a fresh install of a recent version of Avisynth."
I'm using the following:
Avisynth version 2.5 (070518 is on the downloaded exe)
Matroska Splitter
OggSD0995
PremeireAVAPlugin v1.9
DG Index 1.4.9
---So in complete desperation I have uninstalled every codec and Premiere and I have and installed only the above. I still get the same error. As a last resort (saying this because I know it's not the most up to date thing. I installed the codecs/plugin/avisynth from the AMVapp and I get the Premeire error of "the file appears to have no media data".
What concerns me even more is that the tests in AMVapp wouldn't run. Said low memory and closed on all but one, which doesn't make sense with a 3.0ghz and over a gig of ram (of which is more than I had editing with Premiere for my last video).
The avs and .ogm files open and edit fine in VDubMod and on top of that I've tried the direct stream copy of an .avi and imported that into premiere with a codec error. I can't think of anything else to try.
I'm pulling my hair out trying to figure out what could be wrong. Thanks for any help.
