Hi Everyone, I really need alot of help on what filters to use in avisynth/virtualdub to help clear this laserdisc capture.
I attached a sample clip below and some images. Im trying to make it look more HQ as the best it can.
This is the avisynth scipt that I have so far, I dont even know if its right. Just been going through different filters and testing
what it does and see if it makes it look better. I noticed their are a lot of different dust/scratches randomly throughout the whole film and tried to use SpotRemover in Virtualdub and also tried Despot, but I was so confused on how to use them correctly. Please suggest any filters that will clean this up a bit, I really appreciate it for your help.
I attached new sample files below that weren't re-encoded.
Code:DirectShowSource ("C:\Users\Angel\Desktop\Engine1.ts") AssumeTFF() TFM(mode=1, pp=0) Tdecimate(mode=1)

Trying to understand what you're doing here. Are you capturing to lossy MPEG or h264? These are not "editable" formats for the kind of cleanup you're attempting. Your sample clip is AVC/h264 and appears to be re-encoded, making noise and other problems worse. Below are 2X blowups of two areas of frame 780 inverse telecined but otherwise unprocessed). You can clean this noise, with the result that you'll get banding in your final encode. You've also used AVC/MPEG encoding at YUY2 and with the wrong audio sampling rate and audio mp2 compression for AVCHD/DVD, so I'm not sure what you want for output. The audio duration in your sample is slightly shorter than the duration of the video. Don't be surprised if you encounter audio sync problems, although sync can be fixed later.
I suggest that you not "edit" with non-smart rendering NLE's. When working with animation and doing a ton of cleanup, work with lossless. The re-encoding noise shown in these images will be difficult to clean without serious loss of detail. The images also show DCT ringing, and many frames are outside RGB-16-240 spec when viewed as RGB.
Why are you resizing to 640x480? What do you want for final output?
ED: The line twitter is really annoying, likely difficult to fix without some strong filtering. I'm not sure what caused it. Does the original capture play that way?
Cropping and then resizing alters the image proportions from the original frames. If you crop, restore the original frame size with AddBorders() to replace what was cropped. This will maintain the original image proportions.

You need to do 3:2 inverse telecine, this is definitely a film-sourced disk. (edit: oops, looks like you did that and posted the original)

I added better captures that I did without re-encoding them into x264.
What filters to use to make this look much better? I know forsure to denoise it but how can I remove certain scratches and white and black dots/lines that appear here and there?
You should be capturing at 720x480. But something along the lines of this will help a bit:
import("C:\Program Files (x86)\AviSynth 2.5\plugins\RemoveSpots.avs") LoadVirtualDubPlugin("g:\Program files\VirtualDub\plugins\deflick.vdf","DeFlick") AviSource("TEST1.avi") AssumeTFF() CheckMate(thr=0, max=10, tthr2=0) TFM() TDecimate() ColorYUV(off_u=6) vInverse() ConvertToRGB32() #DeFlick(window size, softening, interlaced, scene change threshold, show scene change) DeFlick(12, 4, 0, 10, 0) ConvertToYV12() RemoveSpots() Dehalo_alpha(rx=3.5, ry=0.1) Bicubicresize(480,480) MergeChroma(McTemporalDenoise(settings="low"),McTemporalDenoise(settings="very high")) Sharpen(0.3,0.0) nnedi3_rpow2(2, cshift="Spline64Resize", fwidth=640, fheight=480) aWarpSharp2(depth=5) Sharpen(0.5, 0.1)
