Jerky Video in 6.1

[chrille2]

Since I upgraded to 6.1 I have got a more jerky video playback
I have to set video playback to highest mode to get is as smooth as I had in 5.5.3 with medium setting.
Actually..the video playback in 6.1 is so jerky with medium setting that it is impossible to work with.

Why is this ?

I am using a low cpu demanding MJEG compression and my computer is very fast.
It shouldn´t make any difference.

if you can put the movie into quicktime format .mov I have two clips of the exact same file one mpeg and one quicktime, the quicktime runs perfectly the mpeg is jerky. I think its because the support for movie files in PT is quicktime, and quicktime just happens to play mpegs too.

Hello Datus

Thanks for your reply.

No the video is not in MPEG , which would of course be jerky cause of the cpu intense decoding MPEG has.

The video clip i s MJPEG and I have encoded it myself, runs perfectly smooth in 5.5.3 but jerky in 6.1

cheers
