Combined movies different Frames Per Second FPS

[lindylex]

I wanted to place to video files together one plays at 59 frame per second (FPS) the other at 29.97. When I place them together I have to match the frames per second. Is there a way to do this with avisyth and not have one become slow motion or the other have to play twice as fast?


This is what I tried below.

aaa = avisource ("C:\Documents and Settings\lex\Desktop\2008_may_25\101CANON\MVI_0287.AVI ", false )
bbb = avisource ("C:\Documents and Settings\lex\Desktop\2008_may_25\101CANON\MVI_0289.AVI ", false )

nnnn = avisource ("C:\Documents and Settings\lex\Desktop\2008_may_25\101CANON\MVI_0338.AVI ", false )
oooo = avisource ("C:\Documents and Settings\lex\Desktop\2008_may_25\101CANON\MVI_0339.AVI ", false )

combineda = aaa + bbb 
combinedb = nnnn + oooo

combined=combineda+combinedb.BilinearResize(640,480).assumefps(combineda)

return combined

Thanks, Lex

Hi-
Is the output format also to be AVI? And you don't want it to be interlaced? Then drop every other frame of the 59.94fps one:

SelectEvery(2,0), or
SelectEven(), or
ChangeFPS(29.97)

If interlaced output is OK, then you can reinterlace the 59.94fps one to make it interlaced 29.97fps.

manono, this works like a charm.

combined=combineda+combinedb.BilinearResize(640,48 0).SelectEven().assumefps(combineda)

This will work also.
combined=combineda+combinedb.BilinearResize(640,48 0).ChangeFPS(combineda)
