Frame blending, restoring old anime

[ArcoCapaz]

This is the video im trying to fix https://b3.thefileditch.ch/DIExbUgWVySLBCsXEbrm.avi

From what i have read in other post, i need the original source to fix it as this video frame type is "progressive", but still i wanted to ask, is there anything i could do? I will upscale and use frame interpolation later and wanted to clean it up a bit before, like dehalo, denoise, deblend... Point me to other post or useful pages where i can read and learn more, thanks

I found a better source https://big.thefileditch.ch/b4/MWnClqjpFnGRakYVgIQw.mkv , playing around with avisynth i manged to fix it for most of the scenes with this

FFmpegSource2("Captain Tsubasa Ep 1 (JP DVDRemux).mkv",atrack=-1)
AssumeTFF()
QTGMC(preset="faster", EZDenoise=10.0, NoisePreset="Fast")
SRestore(mode=-1, omode=6, thresh=12, speed=-1, cache=10)

But for example in timestamp 1:52 there are still blended frames

Doesn't solve the blends around 1:13 and 1:52, but using TFM(mode=7) instead of QTGMC might be faster.
Might be worth looking into exBlend (https://forum.doom9.org/showthread.php?t=175948).

FFmpegSource2("Captain Tsubasa Ep 1 (JP DVDRemux)-00.00.00.000-00.02.25.433.mkv")
AssumeTFF()
TFM(mode=7)
srestore(omode=5,speed=9,thresh=22)

TFM(mode=7) works great, thanks a lot. Using srestore onmode 5 fixes those blends but it also mess up other scenes, ill keep testing.

Those frames get blended like this aa ab ba bb

Given that the underlying cel animation is 8 fps in the section from about 1:52 to 1:55 I suspect those blends are intentional. You can get rid of the blends (and keep every original cel) by reducing the rate to 8 fps. But you'll need to dup back to 24 fps and somehow (manually?) detect those sections and paste them in.

function TFMBob(clip v, int "pp", int "cthresh")
{
    pp = default(pp, 6)
    cthresh=default(cthresh, 9)

    v.GetParity() ? Interleave(TFM(v, mode=1, field=1, pp=pp, cthresh=cthresh), TFM(v, mode=1, field=0, pp=pp, cthresh=cthresh)) : Interleave(TFM(v, field=0, pp=pp), TFM(v, field=1, pp=pp, cthresh=cthresh))
}


Mpeg2Source("MWnClqjpFnGRakYVgIQw.d2v", CPU2="ooooxx", Info=3) 
TFMBob() 

p24 = SRestore(frate=24000.0/1001.0)
p8 = p24.SRestore(frate=8000.0/1001.0).ChangeFPS(p24.framerate)

ReplaceFramesSimple(p24, p8, Mappings="[2673 2772]")

Trim(2612, 2785)

I see, thanks a lot for the help , i have to think about manually editing those scenes as i plan to denoise, upscale... all the episodes.
