using telecide(order=1,post=0) I found the frame pattern to be

0010001000100100010001001000100010001 (repeats)

where 1 is a duplicate.

I'm trying different decimate cycles but nothing seems to get them all. I can't find the right combination of cycles. Can anyone help?

Well, if the pattern stays constant throughout the movie, your best bet would probably be using SelectEvery() to get all non-repeated frames out of your cycle.

If it's not constant, it's probably a job for FDecimate or TIVTC...

Don't quote me on that, though... :)

if the pattern you posted is constant, your true framerate is:
[container framerate] * (1 - [duplicated frames per cycle] / [total number of frames per cycle]) = true framerate
29.97 fps * (1 - 10 / 37) = 21.87 fps

use fdecimete or tdecimate.

or provide an unprocessed sample clip.

Hi-

That's a common pattern used to approximate 22fps (as scharfi says, it's 21.87fps). I would use:

B=TDeint(Mode=1) #or (Leak)KernelBob
SmartDecimate(27,74,B) #very fast

or:

TFM()
TDecimate(Mode=0,CycleR=10,Cycle=37) #somewhat slower

As near as I can tell, you can't get it exactly with Decomb.
