The standard version appears to be free.
For Greg - Thanks. I actually have this, don't believe it is version 2 though. Actually, just checked and it's version 1.87.
I've used it successfully but a while back, I had some issues where it seemed to encode but was randomly dropping a few frames at beginning and end and I could not figure out why. Have you ever seen that? I mean, we need precise frames so that concerned me a bit.
I used it last night for a very short 14 frame thing and it work fine though.
