Oh, yes: I'm also looking forward to see how 2-pass mode performs
compression-wise.

Just so I understood you correctly:
Are you saying to generate pass-statistics for one file (e.g.
video_01.avi) and then use these statistics for *another* (?) file (e.g.
video_02.avi)?

>From how I understand multi-pass encoding, I was assuming that each
2nd-pass requires the statistics for exactly the file to be encoded, but
your message sounds like these stats could be re-used generally somehow?
If so: How does that work? These stats are generated from the content,
so I thought they are highly content-specific?

Thanks,
