View Full Version : 3 Progressive, 2 Interlaced (Not Duplicates)

Alright I have a video that has 3 Progressive followed by 2 interlaced (no duplicates). I am wondering what I should do to achieve 23.976
DGIndex gave it a 100% NTSC, and the D2x file is completely 2's.

Load it into decomb or tivtc. 100% video just means every frame was encoded interlaced (hard pulldown, rather than soft w/flags), so you can't force film it, but can still ivtc.

Yeah I was using the telecide and decimate combo earlier but it wasn't working too well so I thought I might have to do something special. The reason is that I had to start the decimation at the point where the hard pulldown started (there was a bit of intro that was pure interlaced).
Well anyways thanks.

If it's hybrid and you wish to keep the hybrid nature, TIVTC can do that. See VFR (http://www.avisynth.org/VariableFrameRateVideo).

Nah I know about VFR (I used it on trigun and stuff.)
This was just the opening DON'T PIRATE THIS shmoe stuff on it.
Infact that was title 1, the movie was title 2 (with chapters :) corresponding). Just the vobs were showing that garbage.

If video has this pattern: PPPIIPPPII, you should try this script:
xxxSource("xxxxxx")
SeparateFields()
SelectEvery(10,0,1,2,3,4,5,8,7)
Weave()
AssumeFPS(23.976)
The two interlaced frames contains four filelds, 0,1,2,3. 0 and 3 are spare (same from neigbours P frames), 1 and 2 give fourth P frame.
So You obtain exact 29.97 -> 23.976 fps reduction.
This patern is usually used by HDTV 1080i. But if video contains some errors, it will be better use other more inteligent ivtc's, like Telecide....

Sadly, I've yet to actually see a dvd or broadcast that clean. All of them have been edited post-telecine at some point, many pretty significantly, or telecined separately and joined together. I'd rather leave it to TFM than find out there was a 5 minute segment in the middle that broke pattern, after encoding. :p

Why would you have done a vfr encode of trigun? With Trigun all you have to do is a regular IVTC as it isn't hybrid material.

At the time I wasn't entirely sure how to handle credits (they are progressive). Now I got better methods for that.
