hi netlanders.
when using some K-templates I got
underflow results. This won't necessarily
make the MPEG file unusable but might
lead to A/V sync problems, stuttering,
and such.
After some investigation I found out that
some frames got larger than the predefined
buffer size, mostly I-frames.
So when using larger "maximum bitrate"
it would be advisable to set the VBV to a
higher value in MPEG1 encoding.
Some templates only issue 40 KB, others
are 48 KB.
I set this value
MPEG.Video.VBVBufferSize
to at least
64 KB or 96 KB ( at high CQ and
upper limit of 2400 kbps). The values are
65536 or 98304.
The increase
of the resulting filesize is virtualy NIL.
Like the hole K-issue this does not conform
to MPEG1 standard, but I haven't seen
any problems yet. Probably because
standalone DVD player have to work to
even much bigger VBV size in MPEG2
(e.g. 224).
Just give it a try and you might have less
problems than b4.
Obrigado
