[HELP] can't encode but displays finished

[Selur]

but i using mvtoolfps filter set fps to 25, the encoded clip is still 29.97fps

sure, since mvtoolfps is for frame interpolation (= creating new frames) and thus can't be used to reduce the frame rate.

Assuming:
a. your source really is 'top field first' it's 29.976 interlaced you would use QTGMC in bob mode, to get to 59.94 fps) and then use sRestore to lower the frame rate to your desired 25fps.
b. if your source really is 'telecined' you would, first overwrite the scan order to telecine, then use TIVTC to get to 23.976 and then use some interpolation filter like mvtoolsfps/svp/rife/.. to get to your desired 25fps.
-> figure out whether you source is telecined or not. (in case it's really progressive, overwrite the scanorder and to progressice and use sRestore)

get to 59.94 fps then use sRestore works, thanks.

Note that bobbing and reducing frames will also work on IVTC and progressive content, but depending on the nature of the content one method will produce better output than the other.

But happy you got it working.
