Are you sure you don't mean . . . that you want to TELECINE? You really want to take 23.976 fps material, and get it to 29.970fps? Do you realize this doesn't make it any smoother?

Anyway, assuming that you were drunk when you wrote that, take it from me, and I've certainly experimented a lot: decomb is the BEST filter for inverse telecine and deinterlacing. I've found out the hard way. I refused to believe people. I kept thinking, gee, this is good, but it's not quite perfect. The bottom line is there are always compromises, and decomb makes surprisingly few.

mpgd72 you should read Doom9's CCE guides.
They explain that you must encode to MPEG2 progressive and then apply pulldown.exe to the stream created, this way DVD masterization programs accept it.
NTSC DVD's have usually progressive video and it's telecined by the player, that reads fields and frames with the order in the stream. Pulldown does the job to convert progressive stream to telecined stream. It's stupid to encode something progressive interlaced, because it will look worse.

Read doom9's guides first anyway.

JohnMK you should calm down first before replying a post ;)

This is my first post :)

First off, the process you are refering to is simply 2:3 PULLDOWN - also called TELECINEing (aka, converting 24fps FILM to 30fps NTSC). A DROP_FRAME FLAG is added to the 30fps stream to drop one frame out of every 1000 to yield the final 29.97fps.

This is NOT something you want to do with filters, because all this will do is give you extra (duplicate) fields to encode - 25% extra, at that (add 1 frame for every 4). This should be done as a POST PROCESS, because all the 2:3 PULLDOWN and DROP FRAME stuff are just FLAGS in the MPEG header.

I don't know what TMPG is doing with its TELECINEing process, but I imagine that it is only setting the proper flags.

If the 23.976 clip that you have is not jerky, then your problem is your misapplication of the technology at your fingertips. Just run the program PULLDOWN.EXE (it's a commandline application) and input your options (do NOT set your sequences as PROGRESSIVE - only the FRAMES are progressive)

This is what you need. It's the best solution, IMO. Thanks Neuron2 for helping me find this out.

Neuron2,

Please......
Sometime people use hard way to learn something.

Negative comment will just discourage others to participate further.

Peace...:)

All is well that ends well. I want to take this space to apologize to anyone I have upset. I guess I wasn't paying attention to what I was being told to try. It was a miscommunication on my part. I have learned a lot from this post and will make sure to handle things a differently in the future.
