Decomb 5.2.1 released
I've made an update to Decomb.
Decimate modes 0, 1, and 3 now use the same windowed comparisons as mode 2 does. This is the strategy used in Dup() and it gives more accurate and reliable decimation. Somehow, it got omitted from 5.1.1. Please get it from my web site. |

Hmmm, weird. Glad to hear it's fixed
Also, have you considered making a version of dup that works with the individual blocks, not just the entire frame? You could do something like what dup does now, except use neighboring blocks to determine whether to update a particular block or not. Might or might not be worthwhile due to block-like artifacts (but definately higher compressibility).

Hi,
My knowladge about deinterlacing/ivtc is none, I didn't have to do it until today. Today, however, I finally decided to do something about one horribly telecined music video. I read (among other things) decomb's manual and I have a suggestion. Decimate(mode=0) is what I'm using (after telecide), as my source originated from film. Now, the manual says that it detects two most similar frames and discards second of the two. How about the ability to: - discard the first of the two - blend the two frames into one, which will halve the noise if we're lucky From what I see in my clip, quite often one of these frames has some ghosting while the other doesn't. The choice between the 3 methods could help, or at least be useful, with removing the ghosting as much as possible. If what I said is rubbish then excuse me for wasting your time thanks, Radek |

Blending for noise reduction is not a proper decimation function, in my view. You can use the Dup() filter (written by myself and sh0dan) to achieve that functionality. |
