24 to 25fps speedup with audio synced - how?

Postby bartiboro » Sat Sep 10, 2011 8:54 pm

Hi,

i want to speedup all streamed 23.976fps mkv's to 25fps to get rid of telecine judder on tv, but with avisynth assumefps(clip, 25, 1) audio is slower than video.
Is there any avisynth script that solve this issue?
Mencoder additional parameters don't work - data is corrupted is displayed.

Thx in advance.

In the expert mencoder options there's an example:
Code: Select all
#to remove 24p judder on a 50hz TV: framerate == 23.976 :: -speed 1.042709376 -ofps 25

I havent tested it my self, but it sounds like what your looking for.

I know it and tried - in earlier ver. of ps3ms it works but now in 1.40 doesn't - maybe its beta issues?

Hmm and. using just -ofps 25 causes async, right?

-ofps 25 works - tv switches to 50hz but audio is out of sync
with speed tv is not switching and movie doesnt start to play.
