Do AviSynth and VirtualDub has a filter that gets rid of video blur on the edge?

You should probably post a short and untouched video sample showing the problem.

Not an blurry edge. I am talking about videos with black borders. There are some videos that have slight artifact at the clear edge of the video with black borders. Are there any ways to make it look clean after cropping out all black borders? Here's the example. Look at the left side.

I see ringing artifacts. For example, in this contrast stretched 8x enlargement of the area around the letter x in the word jukebox:

Is that what you are talking about? Some of it i scaused by compression, some caused by scaling SD to HD, possibly other causes like sharpening filters, etc. There are some filters designed to alleviate them but they can be very damaging to the picture. Is that from your source or is that after you processed it?Last edited by jagabo; 13th Jul 2019 at 20:38.

You can reduce the first generation halos with AviSynth and FineDehalo(rx=1, ry=3):

The video also needs to have the chroma better aligned with the luma, ChromaShiftSP(x=2.0, y=1.0):

You also have the problem that it is a low resolution low bitrate image hence the stepping on edges.

I've download FineDehalo and ChromaShiftSP files, but they are both in avsi format. I've put all of those contents into AviSynth Plugin and SysWOW64 folders, but filters still don't work.

Yes it is. I've downloaded other filters and they work just fine without any problems. I don't know if there's any requirement files missing. Are files supposed to be converted from avsi to dll?

[QUOTE=jseo13579;2555184]I don't know if there's any requirement files missing.
Why didn't you check when you downloaded the avsi files?

No. -
I don't understand, but dll files are not included in the download. I've downloaded zip files and none of them include dll files. Where do I get it?

I just downloaded masktools2-v2.2.18.7z from AviSynth.nl (which lead to github) and found this inside:
Code:C:\>dir/s/b/a-d masktools2 C:\masktools2\LICENSE C:\masktools2\old_README.md C:\masktools2\old_readme.txt C:\masktools2\README.md C:\masktools2\with_dual_filter_signatures\readme-when-to-use.txt C:\masktools2\with_dual_filter_signatures\x64\masktools2.dll C:\masktools2\with_dual_filter_signatures\x64_xp\masktools2.dll C:\masktools2\with_dual_filter_signatures\x86\masktools2.dll C:\masktools2\with_dual_filter_signatures\x86_xp\masktools2.dll C:\masktools2\x64\masktools2.dll C:\masktools2\x64_xp\masktools2.dll C:\masktools2\x86\masktools2.dll C:\masktools2\x86_xp\masktools2.dll

I suppose that's 7z file which does not open on my pc. What do I need to install?

[Attachment 49580 - Click to enlarge]. Now I have installed all required files for FineDehalo and ChromaShiftSP, but both of them don't work. -
Forget FineDehalo() for now and concentrate on ChromaShiftSP() -- it doesn't have any third party requirements so it's easier to diagnose. Remove the FineDehalo() line from your script and add the ChromaShiftSP() line I gave you earlier. Do you get a "no function named ChromaShiftSP" error when you open the script? If so, import the AVSI manually in your script by adding this line to the top of the script:
Code:import("C:\Program Files (x86)\AviSynth\plugins\ChromaShiftSP.avsi")

I should have saved FineDehalo and ChromaShiftSP avsi page as dll, but instead I've saved it as mere document file. Anyway, how do FineDehalo and ChromaShiftSP actually work based on increasing and decreasing number? What is ChromaShiftSP used for?
-
I don't understand what you mean. AVSI files are AviSynth scripts, not dll files. You save them as plain text just like any other AVS file (you can open and view them in Notepad). The AVSI extension simply tells AviSynth to open the script automatically when it's found in the plugins folder.
FineDehalo() removes oversharpening halos. ChromaShiftSP() shifts the chroma (color) to better align it with the luma (greyscale intensity). Read the docs. Exeperiment for yourself. -
I used FineDehalo and ChromaShiftSP setting you've posted, but I don't get the same result. Right edge gained an artifact. Anything I'm doing wrong?
[Attachment 49597 - Click to enlarge]. -
Why is the image a different size and aspect ratio? The chroma artifact at the right edge is because of the black border. Crop the black borders away before shifting the chroma. And the chroma is shifted too much now -- probably because if the smaller image.
As was suggested earlier, you should post a sample of your source video for more concrete suggestions.
