Can Ivtcblend blend duplicates?

[McQuaid]

I was looking at this (http://www.avisynth.org/index.php?page=IvtcBlend) at avisynth.org and not really sure if this is a quick way to process at ivtc.

Looking at some of my clips after using decomb and bringing the frame rate down to 23.976 there are still duplicate frames as the source is cartoons and many of them do that.

I'm wondering if the above can be used after doing a decomb (using don graft's) and blend duplicate frames to bring down the s/n ratio?

My Dup filter is specifically designed for that function. You can get it at my web site.

I use your decomb for ivtc and read up on your dup plugin again.

From what I understand, the ivtcblend is actually blending the detected dups instead of copying; so you still benefit from from dup frames, but bring down the s/n ratio. I guess similar to the thread (http://forum.doom9.org/showthread.php?s=&threadid=28438&highlight=combine) about averaging two analog captures.

Do you think it would be worth it to add this to your dup filter? And I've seen toons where there is even 3 dups in a row with low motion scenes. It would be a little more tricky applying equal weighing to 3 frames though.

Ok. I was just going by your web site. Just downloaded it and reading the readme, didn't realize it the filter does have a blend option. And it sounds nice that it has an option to choose last frame of dups instead of first.

Going to try this on my last cap. :)

Also just thought of something. At first I thought this should be run right after decomb, but would it help in some cases if run after noise removal filters. This would definately be bad for the blend option because of trying to get a better s/n ratio. But in the case of choosing first/last frame of dups, I was wondering if this would help or hurt detection and also possibly make the comparion faster.

And resizes as well. I'm wondering if duplicate frames become more similar or different after filters/resizing is applied?

I just finished reading the dup thread. Were those crashes resolved with latest avisynth? And did you go any further with trying area based comparison? I'm just wondering about that example of a person walking in the distance. I haven't tried this yet as I'm still on 2.07. I guess I really should got to 2.5.

It's not an option. It always uses the last frame.

Thank you for your interest in my work and for any results you may care to share with us in the future.
