Hi Richard,
In that case it will kill the majority of the performance benifit
provided by the caches, because there's very little locality of
reference for the cache to compensate for. It moves through at least

At any rate I checked out ffmpeg's mpeg2 encoding vs mpeg2enc on
my G4 Powerbook. Yes, ffmpeg has a big speed advantage (~2x) but
the resulting output is 'grainy' (same bitrate, no B frames) (and the

You can set the bitrate to 9000 kbits/sec but with a high '-q' the
encoder will only use a fraction of the maximum bitrate. Lower -q
and watch the encoder come closer to the maximum rate.
You set the maximum bitrate and then adjust -q so

For the movie as a whole. Shorter scenes will, as you have seen,
run up against the limit and there's nothing wrong about that.

Hello.
I am making a SVCD where the MP2 audio is encoded from
two different sources (one AC3 file and one OGG file).
How can I join the MP2 segments into a unique file for
multiplexing with the MPEG2 video stream?

Ok. I noticed that for some chapters on the DVD, the average bitrate reported by mplex
was almost 50% of the max bitrate!

Ah, I see my posting made it out - I never saw it come around.
