Anything like D.Graft's Decomb available for RGB ?

[grannyGeek]

I've googled for "IVTC RGB", and maybe I need to expand my criteria.
I only found an alpha test version of something called ITS.dll (on a Japanese webpage, and not sure if Google is translating the page accurately.)

I'm working on a RGB capture < don't ask! > and the source vhs tape got mangled, so re-capture in YUY2 is not possible.

I love the Decomb package for the tweakable settings and the good help files (and thank you to Manano and Jagabo and Abond for introducing me to it). But it doesn't work in RGB.

Can anyone recommend a VDub or Avisynth filter for Inverse Telecine and Decimate that works in RGB and can have paramater tweaks the way Decomb does?

Please forgive me if I am overlooking something under my very nose.

Hi-

Here's a list of all the AviSynth IVTCs:

http://avisynth.org/mediawiki/External_plugins#IVTC_.26_Decimation

I was just checking some of the older ones, and all, as near as I can tell, require at least YUY2, if not YV12. The first AviSynth IVTC I used, a year or so before Decomb was introduced, was GreedyHMA, and it was the first AviSynth IVTC, I'm pretty sure. And it requires YUY2. So, I think you're either stuck with the crummy VDub one, or, better yet, let the old free version of TMPGEnc (if you don't have a more recent one), do the job. It has an automatic IVTC, but you can also tweak every frame, adjusting the pattern here and there, if you wish.

Here's a guide to using TMPGEnc for IVTCing:

Or, just change the colorspace of your RGB source and IVTC using an AviSynth IVTC.

Manano, thank you for the links.

I'll give a try to using my old TMPGenc just to see what happens.

I did just run across Graft's VDub versions -- Telecide.vdf and Decimate.vdf, and will give them a try too. (from 2001, so I guess he concentrates on the Avisynth versions now.)

But I think your suggestion to convert color-space is probably the most practical, especially since I'm comfortable now with Decomb.

Thanks again


OOPS -- your link to the doom9 tutorial doesn't work -- I think they are having site problems, I've had "connection refused" for a bunch of links to doom9 today.

I just checked the link again, and it's working. If not, go to the main Doom9 News page (not the Forum), then Guides, then Document Overview, scroll down to near the bottom to Other Stuff, and the IVTC Guide, using TMPGEnc.

Thanks for going above and beyond the call

Maybe my corporate firewall just got meaner.

In case others might find this thread someday, just a quick report back that I tried Telecide.vdf and Decimate.vdf (I think Decimate might be a beta).

Sadly, audio ended up delayed and entirely out of sync, and my Patience Locker is empty right now, so I didn't take time to try to make it better.

Graft's Avisynth Decomb package has Deep Magic that keeps the audio in sync, so I will continue to use that instead.
