I wanted to make an encode of this DVD I have so I used makemkv to make the segments on the DVD into mkv files. There seems to be one file that behaves differently than the rest. I see combing on the video and alot of it on very high motion scenes, it's weird because the other segments on the DVD dont have combing like this I will provide the mkv file makmkv made from the source DVD which I own. I wanted to deinterlace it plus encode to x256 for plex streaming but the combing is really severe even on the deinterlaced encode. I tried using xmediarecode and hybrid. The combing is mostly visible during transitions and high motion scenes. Also it doesnt happen on every scene just every so often. I was wondering if the material is telecined but I'm not sure how to tell, tried counting the frames but I feel like I'm doing that wrong.

Here are some pictures to show the combing I'm describing

It was also hard telecined from 25p before the resizing. You could blur the two fields together and decimate back to 25p. That will nearly eliminate the combing (those frames will look like double exposures though) but you will lose some vertical resolution.
Code:Mpeg2Source("title_t02.d2v", Info=3) TFM(pp=0) BilinearResize(width, height/2).Spline36Resize(width,height) TDecimate(mode=2, rate=25.0) # or TDecimate(Cycle=6, CycleR=1) to get 24.975 fps

this looks really well thank you so much, I was looking for this kind of input because I had a feeling it was telecined just didnt know how to go about from there.

I worked out a way to blur only the frames with screwed up interlacing:
Code:Mpeg2Source("title_t02.d2v", Info=3) decombed = TFM(pp=0) blurred = decombed.BilinearResize(width, height/2).Spline36Resize(width,height) testclip = decombed.Sharpen(0.0, 1.0) # enhance any residual combing ConditionalFilter(testclip, blurred.Subtitle("B"), decombed, "IsCombedTIVTC(6)") TDecimate(mode=2, rate=25.0) # or TDecimate(Cycle=6, CycleR=1)

Are you using any other filters because your output looks much more clear than mine, mine is a bit more blurred.

Disregard that last post, didn't see the sharpen on the script itself, thank you so much jagabo! this thread can now be closed, problem solved on my end.

Note that the Sharpen(0.0, 1.0) isn't sharpening the picture you see. It's sharpening the picture that's used to determine if there is any combing in the frame. The vertical sharpening enhances the combing making it easier for IsCombedIVTC() to detect it. If combing is detected the blurred frame is used, if not, the unblurred frame is used.
-
Yes in the case of that script it is, I just meant in the first video you shared it seemed more clear vs my blurry one. If you run the sharpen plugin by it self it should clear up the image a bit, correct? Only for the 1st script. The second one is kinda jarring like you said due to the blurry and non blurry frames.
-
In the 1st script you posted did you use any other filters than the one you shared? because I used that script but your output looks much more clear than mine, notice in the pic I sent you can make out the background objects easier the lines on them. On mine they look smeared and blurry.
