I don't know. Why don't you run a few tests and post the
results? :-)
What I'm doing now is running a few tests to see how the
bitrate/filesize changes as the GOP size is bumped up by
adding in P frames. Started with 'I' only, then 'IP', then
'IPP', and so on. It'll be interesting to find the point at
which the decrease in filesize/bitrate levels off - adding
1 and 2 P frames dropped the size a _lot_ but I expect that
to taper off as the GOP size increases.
Cheers,
Steven Schultz
