Help with script for split interlaced and 3:2 progressive video

[rack04]

I have a video file that has sections of pure interlaced video and 3:2 pulled-down progressive video. Is there a way to treat these sections differently? For example:

Frames 0-353 are pure interlaced video

I can apply the following script for this section:

LoadPlugin("C:\Program Files\DGDecNV\DGMultiDecodeNV.dll")
DGMultiSource("C:\Personal\Videos\300.dgi", deinterlace=1)

Frames 354-590 are 3:2 pulled-down progressive video

I can apply the following script for this section:

LoadPlugin("C:\Program Files\DGDecNV\DGMultiDecodeNV.dll")
LoadPlugin("C:\Program Files\TIVTC\TIVTC.dll")
DGMultiSource("C:\Personal\Videos\300.dgi")
tfm(order=1).tdecimate()

Is that the movie 300? What parts are pure interlaced?

The dilemma is what frame rate to render it at. One option is a VFR encode.

Yes. It is pure interlaced when the director is narrating.

Ah, I see.

See my edit above.
