Deghosting and de-logoing - Need help

[tapiocattundra]

Hello,

This is my first post here so my apologies if I'm doing anything wrong. I'm trying to de-ghost and de-logo a DVD, and I'm having trouble removing the ghosting with the filters in Hybrid, as well as getting InpaintDelogo to work. I only really have experience with Hybrid, so any help would be appreciated.

Attached are screenshots, the logo I wanna remove is in the top right and is static, and the ghosting is more apparent in in farther shots usually.

You need to have experience with AviSynth, what GUI tool is in use is not important. First you need to install all requirements mentioned there: https://github.com/Purfview/InpaintDelogo

got a sample of the source you can share?

Hope Google Drive is okay, file is about a gigabyte: https://drive.google.com/file/d/1IfcfI1gBSIKOv9d2gzpfeZ9CpNUGT0fC/view?usp=sharing

I've tried Avisynth before and generally I can't seem to wrap my head around it for some reason, a GUI does help a lot but I do recognize there's some limitations with them.

That's a reencode, DVD content should be MPEG-2 not AVC => sample is useless.
(Also: I only see some motion blur and blending between scene changes, potentially due to wrong 'deinterlacing',..)

Getting back to this project after a lot of life happening, here's the original file without any encoding, only compiled with MakeMKV (taken from a Japanese bootleg DVD, I've done no editing): https://drive.google.com/file/d/1L36k9qMuikrQYwiGR3vXTxri-rkQ3slm/view?usp=drive_link

Let me know if this helps at all

When using Hybrid, if you have a NVIDIA cards, you could try proPainter (which is part of the torch-addon) for the delogo.
It's slow but seems to work fine

Ps.: content isn't interlaced, but field shifted, so use TFM instead of a deinterlacer. (I did not notice any ghosting)

For ghost removal use Overlay() to subtract a blurred and horizontally shifted copy of the main image.

For logo removal, I have used vs-propainter since it allows filtering only a region around the logo. It worked very well but it is a bit slow. It also requires an Nvidia graphics card. I used an RTX 4070. Instructions on how I installed and used vs-propainter can be found in the forum post below:

Thank you all! The logo removal looks great (and I do have a NVIDIA card), I'll be sure to try it out. For the ghosting, it's hard to explain exactly what I mean but it's almost like a ghost/reflection of the image in some shots, not sure if that's intentional.

Ghost removal:

LWLibavVideoSource("Freaking Out.mkv", cache=false, prefer_hw=2) 
TFM(pp=0)

Overlay(last, last.BilinearResize(width/32,height).Spline36Resize(width, height).Crop(0,0,-36,-0).AddBorders(36,0,0,0), mode="subtract", opacity=0.08)

Ah, applying retinex I can see what you mean.
