De-Interlacing properly and changing 25FPS of DVD to 24FPS

[Akuma786]

Hi,

I like to de interlace this dvd and change frame rate to 24fps and improve picture quality for better viewing.

Can anyone help with a script on Avisynth please. I would kindly appreciate any suggestion.

Here's an attempt using removedirt, bwdif and mcdegrainsharp.
The source is not really interlaced, but it benefits from something particulary because of the subtitles.

What code did you use there, Dave?

Thank you. Can i ask for the script so i can test it on full DVD in Avisnth please. Also can i crop the borders and still maintain the correct aspect ratio. I tried on Avisynth but my skills within avisynth isn't great.

The video is not interlaced.

Deinterlacing would create a mess, and even using QTGMC as a noise reducer won't really give you what you want.

You need to use one of the film restoration scripts posted over at doom9.org by VideoFred. Here is a link to his original scripts:

The power of Avisynth restoring old 8mm films

I have posted my own version of his script in some of those same threads. Here is a video of the before/after from Fred's original script. Later versions do an even better job:

Film Restoration Example

My contribution was to add better dirt removal. The original example above didn't remove much dirt. Here is a before/after example which clearly shows how much dirt can be removed:

It seems to be a 1.66:1 movie rather than 16:9 (or it was badly cropped/resized), so some side borders will remain for 16:9. It also seems to have framerate conversion and deinterlacing artefacts ....
Maybe try something like this:

LWLibavVideoSource("VTS_01_1.VOB")
Crop(8, 56, -0, -64)
santiag() #removes the residual combing artefacts
spotless() #removes the scratches
temporaldegrain2() #or use a simpler (faster) denoiser
spline36resize(1200,720) #square pixels
addborders(40,0,40,0) #pad to 1280x720
assumefps(24) #slowdown to 24fps if really needed
prefetch(8)

Thank you Sharc, that look soo much better.

side note: you might also want to address the chroma shift.

Something like this you mean?

LWLibavVideoSource("VTS_01_1.VOB") #assuming 601 source
colormatrix(mode="Rec.601->Rec.709",clamp=0) #change the matrix for SD->HD upscale
Crop(8, 56, -0, -64)
santiag() #removes the residual combing artefacts
spotless() #removes the scratches
temporaldegrain2() #or use a simpler (faster) denoiser
spline36resize(1200,720) #square pixels
addborders(40,0,40,0) #pad to 1280x720
assumefps(24) #slowdown to 24fps if really needed
prefetch(8)

No, looking at the red areas, i.e. the red lamps the chroma seemed to be shifted.

Thanks for the heads up, I managed to fix that now with ChromaShift. much appreciated.

[Sharc]

Another proposal you may try is to sharpen the chroma and then apply a minor shift only:

LWLibavVideoSource("VTS_01_1.VOB")
colormatrix(mode="Rec.601->Rec.709",clamp=0)
Crop(8, 56, -0, -64)
santiag() #removes the residual combing artefacts
spotless() #removes the scratches
temporaldegrain2() #or use a simpler (faster) denoiser
MergeChroma(last,Spline36Resize(width/2,height()).aWarpSharp2(depth=30).Spline36Resize(width(),height()))
chromashiftSP(1,1)
spline36resize(1200,720) #square pixels
addborders(40,0,40,0) #pad to 1280x720
assumefps(24) #slowdown to 24fps if really needed
prefetch(8)

[Akuma786]

I'll give that a try. Thanks Sharc, much appreciated.
