View Full Version : mvtools - 60P to 24P - Problem at scene change

Hi all,

I'm using mvtools to convert a 60P film to 24P.
The problem is, at each scene change mvtools creates a one frame dissolve instead of a clean cut.
Is there a threshold setting somewhere? Is there some way to make mvtools smart enough to distinguish a scene change?

:thanks:

From what I've gathered, one can only have the choice of interpolation or frameblend.
If you want to keep a scenecut as-is, I would split into clips and process separately.

What do I add to experiment with this?

Here is the script I'm using:

a=AviSource("Your_YUY2_movie.avi")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\mvtools.dll")

backward_vec = a.MVAnalyse(blksize=16, isb = true, truemotion=true, pel=1, idx=1)

forward_vec = a.MVAnalyse(blksize=16, isb = false, truemotion=true, pel=1, idx=1)
return a.MVFlowFps(backward_vec, forward_vec, num=24, den=1, ml=100, idx=1)

BTW, I'm trying desperately to avoid chopping up into individual clips. This is a finished movie with over 1,000 scene changes!
