Progressive & Pulldown

Hi,
I would like to recode some video with X264. But I am not sure how to work with pulldown files.

Here is a sample:
VideoFile

I will use DGindexNV to index and crop the file.
Do I have to remove the pulldown before endcoding with X264?

I use DGIndex but suppose the steps to take are identical for DGIndexNV. Make the D2V project file (or whatever it's called in DGIndexNV) using Video->Field Operation->Forced Film. That will give you a progressive 23.976fps D2V ready to use in your AviSynth script.

Your sample was encoded as progressive 23.976fps with 3:2 pulldown (aka 'soft telecine'). Using Forced Film strips out the pulldown and returns it to its original progressive state.

Thx. In DGindexNV there is no "Forced Film" Option. There is shown a framerate of 29.97.

Edit:
Found the option in the "DGDecodeNVManual".
Code:
fieldop: 0/1/2 (default: 0)
0: Honor Pulldown Flags
1: Force Film
2: Ignore Pulldown Flags
