check sum different than previous pass?

[videocheez]

Each time I try multipass VBR with a particular AVI I get an error that says video check sum different from that of previous pass and source data or time code may be different. Any suggestions as to what might be going on. I will include a copy of the Avisynth script and the log file:

Thanks in advance,

obviously you didnt do a search at all, cause that error is littered thru-out this forum.

do a search using the title of your post (without the ?) and you'll find your answer.

It's true this has been dealt with all around gthe forums here.
Yet, I just want to tell you I used the CRC patch available here and there, and got rid of all these checksum errors. Of course, this is a trick since there probably IS a real error somewhere and the patch just prevents CCE from mentioning it. Yet, my backups are perfectly fine with the patch applied and I couldn't notice any problem in the encoded video (I checked it very carefully).

I would say go for the CRC Patch. Sometimes having a solution is better than looking for explanations for months :D
