using SelectEvery() to get desired fps

[wiseant]

Hi

Couldn't find the answer after searching how to use SelectEvery() to yield a 29.970 fps interlaced output clip

I get these framerate changes:

ffvideosource("D:\23.976fps")
SeparateFields
SelectEvery(8, 0,1, 2,3,2, 5,4, 7,6,7)
Weave
#23.976 gives 29.970 fps - OK


ffvideosource("D:\24fps.mp4")
SeparateFields
SelectEvery(8, 0,1, 2,3,2, 5,4, 7,6,7)
Weave
#24 gives 30 fps -

is it OK to convert/change/assume fps of 30 to 29.970?


ffvideosource("D:\25fps.mp4")
#25 gives 31.250
SeparateFields
SelectEvery(8, 0,1, 2,3,2, 5,4, 7,6,7)
Weave
#25 gives 31.250 - not OK


What SelectEvery() will give me:

25 fps to 30.00 fps and ?29.970 fps

23.976 fps to ?30.00 fps

24 fps to ?29.970 fps
