Reducing GOP-Sequence of encoded MPEGs...

[Peacemaker2000]

i've used scenarist for all my dvd-projects now, but now i want to burn a tv-series one of my friend captured but scenarist rejects the m2v-files because the gop-sequence is to long (IBBPBBPBBPBBPBBPBB) now i set the number of P pictures in TMPGEnc to 4 and scenatist accepts these video for all newly encoded mpgs, but how can i reduce the gop-sequence of the existing mpegs because i don't want to loose them. hope there's a way without much re-encoding or much quality loss :(

Is that true, all your GOP are 18 frame and Scenarist rejects? 18 frame GOP are OK for NTSC DVD, so maybe there are some longer ones, or you're making PAL. Since a GOP must begin with an I frame, there is no way to reduce the frames without re-encoding.

oh yes, i forgot, i'm making a pal-dvd ... ok, there's really no other way? :( ok, but how do i re-encod mpg-files? and how about the quality loss of the files?

i found a way with very little quality loss, i doing it with dvd2avi / avisynth and CCE 2.6 multipass ... and it works great!
