Help with improving this video post QTGMC de-interlace

[Sharc]

Maybe before re-istalling everything you may want to test the source filter and script step by step by inserting 'return last' at the various positions in the script to see where the problem eventually materializes.
But as everything works fine with the LWLibavVideo source filters why not just stick to it?

Good point! I have worked through each plugin and the issue is with QTGMC, I have then narrowed it down to the parameters "NoiseProcess=2" and/or NoiseRestore=0.4

QTGMC(TR0=2, TR1=2, TR2=1, Rep0=1, Rep1=0, Rep2=4,
  \ DCT=5, ThSCD1=300, ThSCD2=110,
  \ SourceMatch=3, Lossless=2, Sharpness=0.1, Sbb=0, MatchPreset="slow",
  \ NoiseProcess=2, GrainRestore=0.0, NoiseRestore=0.4, NoisePreset="slow",
  \ StabilizeNoise=false, NoiseTR=0, NoiseDeint="bob")

NoiseProcess=0 - works
NoiseProcess=1 - fails
NoiseProcess =2 - fails

NoiseProcess=2 and NoiseRestore=0.0 - works

Any NoiseRestore value >0 fails.

I am happy to proceed with LWLibavVideo, but I would like to understand why the issue does not surface with it. Also what is wrong with my avisource().

Maybe your AddGrainC filter is out of date?

Put these two lines right after AviSource and post the screenshot:

Info()
Return(last) #yes it skips all the filtering on purpose

Do the same with LWLibavVideoSource and post the screenshot.

Will try re-download! Edit - I was missing that plugin - but problem still exists. When I worked my way through the QTGMC dependencies (core and optional) I dont think it came up.Could there be others I am missing?

So AviSource decodes as YUY2 and LWLibavVideoSource decodes as YV16!

Since the latter seems to work for you, maybe a simple ConvertToYV16() right before QTGMC when using AviSource is all what's needed to fix it. It's a lossless operation.

Es funktioniert! Thank you, much appreciated!!
