Filtering help needed

[x264]

are these the images from before or after avisynth?

I took those screenshots using avspmod.

[jagabo]

Some of the restored footage in The Good, the Bad, and the Ugly was taken from moldy old prints.

Looks like mostly blue channel affected. How many frames are affected, and what is the distribution / pattern ? If it's just this one scene , can you upload the clip ?

This looks like it will be tough to do a good job without manual work & masks, but there might some tricks you can use depending on the pattern

[jagabo]

For a few frames here and there you can try replacing them with motion interpolated from the frames before and after.

https://forum.videohelp.com/threads/352741-Frame-interpolation?p=2226119&viewfull=1#post2226119

For example, InsertFramesMC(100,2) will replace frames 100 and 101 with motion interpolated from frames 99 and 102.

I can't get that clip (even after remuxing) to play (or otherwise decompress) properly in any player or editor:

[Selur]

seems like the file is missing some headers otherwise at least mediainfo should show resolution&co,..
-> without a proper source, nothing to do

MediaInfo shows the properties:

But I've tried several VC1 decoders and none of them gets a clean video.

[Selur]

doh used 'save as' instead of following the link (ffplay works fine)

[poisondeathray]

works ok here

mkvtoolnix , ffvideosource()

[x264]

I used DGIndexNV to trim the source.

[Selur]

raw +
avisynth + DGSource works fine
avisynth + FFVideoSource shows only a single frame
avisynth + LWLibavVideoSource -> crash

remuxed to mkv
+ mplayer: broken
+ DirectShow based player with Hardware decoder: everything is fine
seems like libav has some problems with the stream depending on the used version

Since only the blue channel is affected, ideally you want to limit repairs to blue channel.

1) One approach: The distribution of the artifacts means some of the yellow spots are amenable to heavy dirt removal plugins by applying to blue channel (basically cleaning the blue channel). You need to ConvertToRGB (709) in order to showblue(), ConvertToYV12(709) to use the dirt removal plugins, convert back to RGB, then mergeRGB (r,g, fixed blue) . The problems with this: a) not perfect; will miss some areas - depends on what filter stack / combo used b) false positives will make blue spots

2) Another method : you can attempt reconstruct the blue channel by manipulating R,G , but the colors will be "off". You would need to do big time color corrections and rotoscope some ares back in (some areas are supposed to be "yellow", like the yellow cape, yellow sergeant stripes etc... those will be faded unless you mask/layer them back in) . Something like colourlike() may help if you're not good with color correcting

[jagabo]

A simple MergeChroma(McTemporalDenoise(settings="very high")) will pretty much eliminate the yellow spots. It's very slow though.

<edit>
Toward the end there is just too much of the yellow discoloration for MCTD.

Does the OS affect the encoding speed?

[jagabo]

Does the OS affect the encoding speed?

Only by a few percent.

[x264]

is it necessary to call the selecteven() after using QTGMC or should i leave it at 60 fps?

[Selur]

Only by a few percent.

32bit vs. 64 bit does 10-15% for me,...
Linux vs. Windows are normally en par unless different decoders/filters are used.
Mac was always slower than Windows and Linux for me.

[x264]

Ok.

[jagabo]

is it necessary to call the selecteven() after using QTGMC or should i leave it at 60 fps?

What are you deinterlacing? What do you mean by "necessary"? What QTGMC() settings did you use?

[x264]

Avisynth script

DGSource("C:\Users\Abhijith Nair\Desktop\1.dgi")
QTGMC(preset="Very Slow")
Dither_convert_8_to_16()
Dither_resize16nr(720,480)
Dither_quantize(bitdepth=10, reducerange=true, mode=6)

It was shot using video cameras so 60p is fine although it kind of depends on what you want to do with it. For example, YouTube will remove every other frame to make it 30fps so you might as well do it yourself, perhaps with some motion blur added to keep movement looking more smooth.

[jagabo]

I agree with manono. If you want to keep full motion smoothness and your playback devices support 60p don't decimate. If your playback devices don't support 60p decimate to 30p.

Keep in mind that, outside of computers, very little supports 10 bit h.264.

[x264]

I got this error when i tried to encoding using x264 10 bit.

[manono]

Did you load the DGDecode.dll? Did you make a D2V project file? What's the complete script you're using?

[x264]

Yes, i did all that.

MPEG2Source("C:\Users\Abhijith Nair\Desktop\VTS_01_1.d2v", cpu=0)
QTGMC(preset="Placebo")
Dither_convert_8_to_16()
Dither_resize16nr(720,480)
Dither_quantize(reducerange=true, bitdepth=10)
Dither_Out()

[jagabo]

Is DGDecode.dll in AviSynth's plugins folder? It should autoload if it is. Otherwise you need to explicitly import it into your script:

LoadPlugin("C:\Path\To\DGDecode.dll")
Mpeg2Source(...)
etc.

[x264]

I have the DGDecoide.dll in the avisynth+ plugins folder. The error appears only with the 64bit build and not the 32 bit build.

[jagabo]

32 bit editors/encoders/players require 32 bit AviSynth and 32 bit filters. 64 bit editors/encoders/players require 32 bit AviSynth and 64 bit filters. You can't mix and match 32 bit and 64 bit components.
