Telecide and Decimate in AVIsynth

3 Replies, 4847 Views

So another question. I'm just getting into using AVIsynth and was trying to IVTC some footage. The original is a 29.97i MKV. I used telecide (tried different settings) and decimate to convert it to 480/23.97p. The original way I was IVTC-ing left a few bad combed frames over the course of the whole movie. This works much, much better but is giving me another problem. Even though the output file is reading 23.976 fps, the speed at which it is playing is way too fast. Looks almost 1.5 speed.

Anyone have any ideas what I'm doing wrong?
I prefer TIVTC.

Code:
WhateverSource()
TFM()
TDecimate()

Both TIVTC and Decomb have a range of parameters that you can tweak.  Have a look on the web or in the readme files for detailed explanation of what they do.  If you really can't clear the combing by tweaking the parameters, try Vinverse.

If truth be told, on the rare occasions on which TIVTC hasn't done its job perfectly off the bat, I've trimmed out the sections that I needed and performed a manual IVTC.  It's laborious, but I find it preferable to tweaking those parameters, which give me a headache.

I don't know about the speed-up.  It sounds as if something has gone wrong during decimation.  If you post your script, someone might be able to help you.  I'll try, but I don't use Decomb, and I've very limited time this week.

Thanks Chewtobacca. I just downloaded TIVTC and going to give it a whirl now. I was doing this:

Telecide()
Decimate()

or

Telecide(1,2,25)
Decimate()
Deblock(25,0,0)

or

Telecide(1,2,25)
Decimate(5)


But get the same speed up. I am processing the AVS in Vdub if that helps. Let me try TIVTC first and see if I get different results. Thanks for the help, Chew
You need something like the following.

Code:
Telecide()
Decimate(5)

I've tested this on footage that I purposely telecined, and it results in the correct frame-rate.

EDIT: I had an old version of Decomb.  It shows long it's been since I used it.  This should work (and does for me).

Code:
Telecide()
Decimate()
