Green Line on right edge of converted file

[DanQ]

I have an MKV file pulled from a DVD using Handbrake, and when I take screenshots, there are several pixels of bright green on the right-hand edge of the image.

I use screenshots a lot for my work, and need to get rid of these green lines. I can't justify manually cropping every screenshot from here on out.

The weird thing is that this line (1) does not appear during playback with VLC; (2) does not appear when I open the screenshot JPG with macOS Preview; (3) DOES appear when I open the screenshot JPG with Gimp; (4) DOES appear when I inspect the image with Firefox.

Searching the interwebs, I have found dozens and dozens of people asking how to get rid of these green lines, giving all sorts of random suggestions, none of which work for me.

If I make screenshots with IINA Player, I don't see any green lines in the output files.

Is there some known, specific, and definitive fix to this problem with VLC? I have already spent several hours trying to sort it out.

I really like VLC and am hoping to continue using it, but seeing a zillion messages on the interwebs about this problem is kind of discouraging.

Thanks in advance

P.S. Running VLC 3.0.17.3 Intel 64-bit on macOS 10.14.6.

Hi, do you have a small sample file that we can use to reproduce the issue?

I am having the same problem, only the line isn't on the right edge, it's on the bottom edge. This has honestly been happening to me for YEARS on and off, only with video converted through handbrake and i'm fairly certain only videos that have been CROPPED in handbrake that have irregular aspect ratios (ie: not 4x3 or 16x9). In old versions of VLC, I used to go into Preferences > Video > Output Modules and change the module to something else and that seemed to work (I think I learned that off of a google search), but now that won't work in the new version, and I downloaded 2.2.5 and I couldn't even get my videos to play at all there for some reason. Here's an example of a screenshot with a green line along the bottom.



I'm using 3.0.17.3 now, and OS is catalina 10.15.7
