I've been trying to restore this source, but the only problem is removing the heavy halo from this source

[Attachment 93115 - Click to enlarge]
The best I got is this script which removes some of it, the heavy parts can still be seen:

Code:

Crop(180, 0, -180, -0)

I'm trying to deinterlace this source from a PAL DVD but this is difficult achieving that because this source is only interlaced from certain scenes
and progressive on the other scenes (It's not any pull down that has to be TDecimate)
Most of the deinterlacers failed me by giving insane jagged line artifacts, the best I got is NNEDI3 which works really great on the interlaced scenes
but gives me jagged lines artifacts (Not as bad as the others) on progressive scenes.
Can anyone help me out here? Thanks!

The venerable old CNR2 has been redeveloped by AI's into CNR3.

https://github.com/hydra3333/vapoursynth-cnr3

Targetted for use on noisy VHS/VHS-C analogue capture files, CNR3 is a temporal denoiser designed to denoise only the chroma (colour), and is derived from the Cnr2 family of filters. According to the original author, this style of filter is suited for stationary rainbows and noisy analog captures.

CNR2 relied on VapourSynth APIv3, which is being phased out, and additionally depended on a serial (in-number-order) output frame request mode which is strongly recommended against under VapourSynth R76+.

Based on CNR2, CNR3 fully implements its recursive temporal model — each output frame depends on the previous filtered output frame, not the previous source frame — which is inherently serial. CNR3 therefore uses the supported vapoursynth APIv4 and the supported fmParallelRequests mode, and implements an internal output-frame cache (with checkpointing and bounded recovery) to deal correctly with out-of-order output frame requests. Output from CNR3 is not bit exact with CNR2, since CNR3 uses slightly more accurate arithmetic.

Latest test result from vspipe to .y4m:

Code:

Output 957 frames in 2.67 seconds (358.89 fps)

IMPORTANT NOTE:

A new better CNR4, inspired by CNR2, has been developed
https://github.com/adworacz/zsmooth#cnr4
which uses a different algorithm to CNR2, however is said to yield a much better result.

Quote:

While Cnr4 is inspired by Cnr2, it provides several key improvements over the original:
- Multithreading friendly (the original Cnr2 was limited to serial processing).
- Roughly 2x faster single-threaded and 10x faster multithreaded.
- Better denoising quality due to the use of past and future frames. Cnr2 only used past frames.
- Significantly reduced ghosting.
- Adjustable temporal radius.
- Configurable temporal handling and weighting modes.

Hence CNR3 is a redeveloped CNR2, more for posterity than anything else.

(Take a look at the background)

[Attachment 93031 - Click to enlarge]
I can't seem to find a good antialiasing script that fully fixes that issue.
Can anyone help me out here? Thank you!
Note: The native resolution of the source is 960x540 and to resize is by using descale

Code:

debicubic(c=1, 960, 540)

(Another Note: I'm an AviSynth user)

When I mean by "motion artifacts", I mean by ghosting, random blackspots, and some weird moving that you can see when comparing two frames apart (I don't know the exact word for that one).

[Attachment 92995 - Click to enlarge]
I can't find a script that fixes this issue without resizing to 1080p which fixes the problem.

[Attachment 92997 - Click to enlarge]
(I used Bilinear to resize to 1080p on the resized image)
It's fine if I resize to 1080p, I just wanna know what's causing this issue and fix it with the new script.
Can anyone help me out here? Thank you!
(Note: This is the QTGMC script I use for normal 1080p/1080i content, which fixes most of the ghosting and some black parts, but not any of the weird moving I mentioned before

Code:

QTGMC(preset="Placebo", TR0=2, TR1=2, TR2=3, Rep0=1, Rep1=0, Rep2=5, EdiMode="EEDI3", InputType=2, NoiseRestore=1.0, NoiseProcess=1, Sigma=1.4, StabilizeNoise=True)

I'm working on a tape that has lots of these defects (mostly green) around lights, hair, straight lines, etc. and need help to properly eliminate them. For the record, I'm using Hybrid and still relatively new to this. I found this post and spent a few hours experimenting with the filters suggested by Selur. Got decent results using KNLMeansCL denoiser on the UV fields, but had to turn up the settings quite high and it desaturates the picture to the point where some colors are nearly monochrome (see images below). Didn't notice much of a change using the other filters, so I finally decided it would be wiser to just consult the forums.

I'll also attach the source clip and a text file with the script I'm using for this test. Any help would be greatly appreciated. I tried to keep this post short, so please ask if you need more info about my workflow or anything else.

Hi everyone,

I’ve been trying to rescue a critical video file for hours and have hit a complete dead end. I really need some help.

The File: A 2.5 GB deleted .mov video file (originally shot on a Canon camera).

The Deletion Details: I accidentally deleted both my Day 1 (d1) and Day 2 (d2) video files. The d1 file went straight to the Recycle Bin and I was able to get it back perfectly. However, the d2 folder/file (the 2.5 GB one) was completely nowhere to be found in the trash bin, which forced me to use recovery software.

The Environment: I am working on a laptop with an SSD internal drive, and the missing files were stored on an external USB drive.

The USB Drive State: The USB drive was working fine initially, but as soon as I used a tool to try and recover the video, the drive started acting up and completely turned into a gibberish format. It now shows random text, weird characters, and strange symbols instead of my folders. The actual D2 folder is completely inaccessible.

The Problem: I tried using Recuva, but it only pulled a file that plays a 2-second black screen in VLC before cutting out.

What I Tried: I ran that broken 2-second file through a repair tool called Untrunc using the working d1 reference video, but the fixed file is still just 2 seconds of black screen. I also tried running Windows File Recovery to pull the data, but it didn't solve the problem. The full 2.5 GB of data seems completely fragmented or locked behind the corrupted USB file system.

I don't have a budget for expensive recovery services, so I am trying to figure out if there is a free tool or a manual way to bypass the gibberish error, safely read the drive, and actually get my D2 folder and video back.

Any guidance would mean the world to me. Thank you so much. ]]> Restoration kalinh https://forum.videohelp.com/threads/420768-help-me-please-im-desperate
