I'm about halfway through editing a new video and when I went to build a new preview of the last 10 seconds or so of clips I had added, instead of the clips, I got a black screen with the following message:
Avisynth: caught an access violation at 0x0d912d85,
attempting to read from 0xffffffff
I thought perhaps there had been a problem building the preview, so I rebooted, wiped all my preview files out, and rebuilt the whole thing. The first 1:40 or so came up fine, while those last bunch of clips came up with the same error. The AVISynth file played fine in Premiere (I was able to find the clips perfectly fine) and they are from varous places in the footage. This was during a long editing run, so no computer settings or files were changed. Any ideas on how to fix this?
