I left out a word by accident - should have said "variable length open GOPs". > I used "-g 15 -G 15" and thought this is closed GOP because -g and -G > have the same size. So I have to use "-c -g 15 -G 15" if I would like to GOPs can be fixed size but still "open" because there can be (B frame) references from one GOP into the next. > cut the encoded m2v-file later? Yes, either add the '-c' to force all GOPs to be self-contained (no references outside themself) OR use '-R 0' and turn off B frames. I have not tried it myself but it was mentioned to me that GOPChop is much happier with streams that do not use B frames.
