@rc55 : yes, variable framerate is no problem. This will happen for very low bitrates, or when DropDupe is used, or for mixed interlaced / ITVC content. I am not sure exactly which documentation you are looking for?
@SocketA: I tried to encode a 60 fps clip with the latest Producer Milestone, and it encodes it, and it even appears to play back, but every 2nd frame has been skipped
I think we should be able to fix this shortly. Thanks for bringing it to our attention.
