Some interlacing in credit roll
What would be the best way to deinterlace this part with avisynth (see snippet) to get rid of the interlacing AND to keep it rolling as smoothly as the original? I've tried several deinterlacers, but the results always seem to be a bit jittery (like: small jump, small jump, larger jump, small jump etc) even though I keep the frame rate at 29.97fps.

My intention was to get something in the 23.976fps to 29.97fps range and to slow it down (if necessary) to the same speed as rest of the movie after deinterlacing and decimating (23.976fps), which all works perfectly well except for the snippet part.
If I wind up with a 60fps part, I can of course still slow it down to 23.976fps but then it would be a tad long. Is there really no way to get this to run smoothly at 29.97 fps? *sad puppy eyes* What I did was this: v1=Trim(0,314175).Telecide(guide=1,post=2,vthresh=25).Decimate(5) # the movie v2=Trim(314381,315064).Telecide(guide=1,post=2,vthresh=25).AssumeFPS(24000,1001) # credit roll; I also tried guide=2 v3=Trim(315065,318853).Telecide(guide=1,post=2,vthresh=25).Decimate(5) # more credits, but no rollin' UnalignedSplice(v1,v2,v3) Everything is OK, I even get the intended number of frames, only v2 is a bit jitterish Last edited by StickHorsie; 13th March 2013 at 18:03. |

Why do the credits even have to be 23.976fps? If for DVD you can keep them interlaced. If for something else you can use a container that supports VFR and at least keep them 29.97, if not interlaced.
Why telecide them if they were never telecined in the first place? Use a regular deinterlacer. QTGMC can add a motion blur to make them appear to play more smoothly at 29.97fps. It's a bobber so add a SelectEven afterwards to get it back to 29.97fps. Your V2 is more jumpy not only because you made it progressive, but because you slowed it down (a very bad idea, in my opinion), thus emphasizing the jerkiness. |

So I cut my losses, completely remade the part (pasted screenshots together, replaced the text & rolled it with Avisynth's Animate), and now it's totally clean, 23.976fps and in far less time than I've already spent on it. New script (which, to my utter surprise, worked right the first time): v1=Trim(0,314091).Telecide(guide=1,post=2,vthresh=25).Decimate(5) v2=AVISource("G:\DVD\GLAEQ\newscroll_720x480.avi") #Q=2, grayscale, no B-frames v3=Trim(315067,318853).Telecide(guide=1,post=2,vthresh=25).Decimate(5) UnalignedSplice(v1,v2,v3) It's just that I had hoped there was some easy MagicCreditRollDeinterlace(mode="SalesBinDVD",quality="perfect",24000,1001) plugin that I had overlooked...

A VFR mp4 would be a possibility, yes... I'll keep that in mind for a backup that's really worth it. Quote:
