Thin Black Line

[Lance_NZ]

A thin black line appears on the right-hand border of my video and I simply cannot make it go away. I have double-checked all aspect ratio etc. It all squares up. The video is 1920x1080 with a 1.0 aspect ratio, but even when I make a sequence using custom settings and put exactly the same values, the problem still occurs. Any ideas? Thanks

To be sure your video is what you think it is...

Exactly what is INSIDE the video you are editing?

Can you take a screenshot of the issue?

If you scale up your video, does the black line disappear?

Try resetting the preferences:

If that doesn't work, try resetting the Workspaces:
Reset a workspace
Reset the current workspace to return to its original, saved layout of panels.
1. Do one of the following:
• Click the Workspace menu icon and select Reset to Saved Layout.
• Choose Window > Workspace > Reset to Saved Layout.

If that doesn’t work, try updating or rolling back your graphics driver directly from the video card manufacturer’s site.

I tried resetting the workspace and clearing the prefrences

Below is what version, setting and final result once exported

I can "barely" see the line you describe... so try using "Scale to Fill" on export and see what happens

Is it still there in your last screenshot?
