your gop 1/18/3/1 = 27mb
standard gop 1/5/2/1 = 26mb
so there is about a 100mb difference if converting to a full movies..
i'll keep testing the setting...so far both look the same quality

Hi rackaboy:
You only got 1 MB difference because you encoded a high action or many changing scenes in those 2 minutes.
There's no advantage there as far as compression.
The GOP works best at the times when you have long scenes and low motion. So it's really an average.
So you'll get an average of 6-7 megabytes per minute on a complete movie.
With the standard GOP of 1,5,2,1 there's not that much compression even on long scenes or low action. So your average MB per minute is much higher.
