IVTC with DoubleWeave + Pulldown(1,4) ?

[ZZCas]

I'm trying to encode the "The Godfather" and there is at least two scenes that need IVTC. I wonder if it would be possible to IVTC the movie by just using DoubleWeave + Pulldown(1,4) in my AVS? If I open my AVS in vdub and I play the movie from there it seem to do a good job. I guess I could use decomb to get the job done but i'm trying to encode as fast as possible and decomb is usually very slow. Is there an advantage of using Decomb even if the IVTC pattern is always the same for the entire movie?

If the pattern is the same, you can use you method of course. But since nearly no movie has the same pattern all the time, I wonder if it will work flawlessly.

You can use IVTC2.2 instead of Decomb this way:

ivtc(44,11,95)

This is in my experience better than decomb and faster than decomb on my P3.

I'm assuming that ZZCas is talking about a DVD rip, but I just thought I'd mention that Telecide has a big advantage with captures because dropped frames will mess up the pattern.

In what ways is it better than decomb, and is the speed difference because decomb does post processing, and your ivtc doesn't? I read the docs for what you recommend and it doesn't talk about if it does post processing or not. You can disable decomb's post processing if you don't think you need it, and its speed will increase too.

Considering you posted 8 hours ago, the speed difference has already been negated by waiting for replies :)

The information is useful for future encodes.

IVTC doesn't do any post processing. Even if you disable pp in telecide, this won't be faster then IVTC, at least on my p3.

IVTC (with the tweaked settings I posted above) is better because it detects pattern changes more accurately than Decomb. Decomb makes too many wrong decisions, especially on dark or transparent scenes.
