decimate without changing framerate?

[bazz]

ive got a problem with a video
i analysed the file and it found it needed to use decimate.
M-in- decimation required Tritical Decimate
ran a sample , framerate came out 19... fps.
I dont want a file with 19fps
i ran a sample with my other filters leaving out the decimate
it looked good except i noticed jerky playback
Is there a way to deinterlace without losing framerate?
thanx

Add:

AssumeFPS(xxx)

to the bottom of the script. For 'xxx' fill in the framerate you want. However, if there's audio included in the video it'll go out of synch

manono, its a 720p = 23.976 fps
audio will be encoded seperate to video

so i just add
AssumeFPS(23.976)

i will check it out on google now i know what im looking for but if anyone can corfirm this id appreciate it

thanks

720p is broadcast at 59.94fps in NTSC land. If you're working with downloaded stuff, it could be anything. But I doubt it's supposed to be 19.xxxfps. Unless maybe it's a silent film.
