Hi,
i feel dumb, somehow my mathematics basics have left the building... ;)
Here some results:
Resolution | MBs | Minsize frame bytes
-----------+-----+---------------------
320x240 | 300 | 48 (kf: 855 bytes)
352x288 | 396 | 60 (kf: 1119 bytes)
480x576 |1080 | 146 (kf: 3000 bytes)
640x272 | 680 | 96 (kf: 1900 bytes)
640x352 | 880 | 121 (kf: 2450 bytes)
720x576 |1620 | 213 (kf: 4485 bytes)
All tests done at 1pass const. quant. 1, pure black image sequence.
I don't find the propper relation, I assume there is an avi frame
overhead involved. The rest of the formula should look like this:
MBs / X + Y * Z + 24 = MinSize
Can someone give me a hand with this? Dan tried and offered to look into
the sources, but maybe someone here has the magic numbers at hand ;)
Thanks for your help,
best regards,
Dirk
