RE: 25i to 29.97i with interpolation - Miranda - 31.07.2023

I have notice on some scenes with panning shots that the video seems to stutter - is there a way to avoid this and make the movements smooth?

RE: 25i to 29.97i with interpolation - Selur - 31.07.2023

Depends on why it's not smooth,..
If it's because of duplicate frames 'FillDrops' or 'FillDuplicateFrames' might help, otherwise interpolating to a higher frame rate might help.

RE: 25i to 29.97i with interpolation - Miranda - 11.09.2023

Is it possible to perform the 25i to 29.97i with interpolation set to Avisynth? I ask because the Spotless controls have superior removal options in Avisynth, it can be set to target white spots only etc.

I tried to set it up last week, but I could not get it to run.

RE: 25i to 29.97i with interpolation - Selur - 11.09.2023

Should work the same way it does as in Avisynth.
Bob deinterlace to 50p, interpolate to 59.94 set output to interlaced.

Quote:Spotless controls have superior removal options in Avisynth, it can be set to target white spots only etc.

Avisynth SpotLess:

SpotLess(clip c,int "RadT",int "ThSAD",int "ThSAD2",int "pel",bool "chroma", int "BlkSz",Int "Olap",bool "tm",Bool "glob",Float "bBlur")

Vapoursynth SpotLess:

def SpotLess(clip: vs.VideoNode, radT: int = 1, thsad: int = 10000,  thsad2: int = None, pel: int = None, chroma: bool = True, ablksize: int = None, aoverlap: int = None, asearch: int = None, ssharp: int = None, pglobal: bool = True, rec: bool = False, rblksize: int = None, roverlap: int = None,          rsearch: int = None, truemotion: bool = True, rfilter: int = None, blur: bool = False,  ref: vs.VideoNode = None)

Are you sure you are mean SpotLess? I suspect you mean DeSpot, which in Vapoursynth is really limited.

I can't get the same scripts to run in AviSynth, lots of errors. Will post some reports here shortly.

RE: 25i to 29.97i with interpolation - humanoid86 - 30.09.2023

try to TWICE encoding processing

1. deinterlacing without a 'BoB' - QTGMC + Progressive or TFF/BFF
2. Interframe 30fps

RE: 25i to 29.97i with interpolation - Miranda - 13.10.2023

I'm not having much luck running the same scripts in AVIsynth.

Any ideas how to fix this? I can't get a preview window to load.

RE: 25i to 29.97i with interpolation - Miranda - 13.10.2023

Is it possible to process the SD interlaced PAL 25fps video through AVIsynth's DeSpot (better noise removal controls) and output the DeSpot version with identical interlacing?

I can then process this DeSpot file through Vapoursynth and interpolate/upscale to 29.97i as usual.

RE: 25i to 29.97i with interpolation - Selur - 13.10.2023

Since DeSpot in Avisynth supports interlaced content, Hybrid will load the source, apply the filter and return the output.
If you set your output to be interlaced, Hybrid will create interlaced output flagged like the input.
This should work fine if your input is TFF, BFF.
I expect this will cause issues if the input is mixed or telecined.

As a side note: it is possible to use Avisynth filters in Vapoursynth (assuming they are both 64bit).
So if it's just DeSpot you are missing, you could add it in a custom section behind the deinterlacing in the Vapoursynth clip. Smile

Here's an example:

core.avs.LoadPlugin("F:/Hybrid/64bit/Avisynth/avisynthPlugins/despot.dll")

# requires colorformat YUV420P8

clip = core.avs.DeSpot(clip, median=False,p1=24,p2=12,pwidth=6,pheight=5,ranked=True,sign=0,minpts=0,maxpts=0,p1percent=10,dilate=1,fitluma=True,blur=1,tsmooth=0,motpn=True,seg=2,color=False,mscene=0,mthres=16,mwidth=7,mheight=5,show=0,show_chroma=False,interlaced=False)

return clip

Note:
a. I added all parameters (this is not required)
b. instead of Avisynths 'true/false' 'True/False' needs to be used
c. The first parameter in your filter call needs to be the clip.
d. the '# requires colorformat YUV420P8' is needed to let Hybrid know that the used filter requires this color format.
e. this works only with progressive filtering, since I haven't come around to write support to let Hybrid know the used filter supports interlacing.

Thank you. Smile

It's basic PAL 25i footage shot on video back in the early 1980s, hence the need to remove video dropouts.

So I need to set ProRes to Interlacing = Top, set De-Interlacing to NONE, is there anthing else I need to set for interlaced output?
