[FFmpeg-user] 1080i AVC-I 100 frame rate conversion

Thank you both,

Intuitively, it didn't make sense to me either to change the speed AND
employ motion compensation so it's great to hear that you agree. That was
what I was driving at when I asked if I should treat 24000/1001 differently
to 30000/1001 and you've confirmed that I do.
So I think I've got a solution to the former but now I have to work out how
best to approach the latter.
The framerate filter documentation says that it interpolates new video
output frames from the source frames. Does that mean it's only suitable for
*increasing* the frame rate or does it also interpolate at the junction
where frames are dropped (perhaps smoothing the transition between "real"
If the framerate filter isn't suitable for 30000/1001 to 25/1, is
minterpolate the *only *motion compensation option in ffmpeg? Could you
please recommend a good set of minterpolate options for my purposes?

Many thanks once again,
