If it doesn't "just work" then it means I packaged it wrong. I don't know if the new version will help this problem, though it could for all I know. I will do a re-package in any case and let you know when the new version is up.

However, I can explain this error. The encoder is a 2-pass process and, for some reason, when it did the 2nd pass the footage was different. The difference was only subtle in 143 frames but it was severe in 8, causing this error.

I'm not really sure what's causing it but I suggest trying it again as it could be something memory-based or something else and it might just work second time around.
