25->23.976 conversion (duplicate frames)

[sebastiaaan]

I've recently stumbled upon some VEVO music videos that were encoded in 25 fps containing duplicate frames. The original framerate of most of them is 23.976.
I did some tests and a basic TDecimate does the thing, however I'm not sure what the best approach is.

For example,

TDecimate(mode=2, rate=23.976)

is perfect. however I end up with an odd framerate of 23.976190 and MediaInfo reports the fps as simply just "23.976" instead of "23.976 (24000/1001)"
Is that any bad or can I just ignore that because it doesn't feel "correct" to me.

Could I just add

AssumeFPS(24000, 1001)

to the end of my script to get to that perfect 23.976023 or would that mess with anything? Or should I use

ChangeFPS(24000, 1001)

instead at the risk of introducing duplicate frames?

f the frame count is correct, AssumeFPS is the way to go
side note for 25->23.976 you might want to try sRestore instead of TDecimate
