White edge on some of my footage (*edit - I just added some screenshots)

I'm noticing a white line appearing on the edges of some of my footage, not all around, mostly on the left and on the bottom. Also it appears, but then disappears again.


As far as I know, I'm using all 4k media.
It seems to be on the footage from my Sony A7iii camera, but also 4k footage I downloaded.

I'm wondering are there some settings I need to adjust, for these particular pieces of footage.

Any thoughts appreciated.

Many Thanks

Any thoughts appreciated..

Is the Viewer background white? If so try scaling up the problem clips a tiny amount.

Hi Tom, thanks for your reply.
I don't think it's white, my project timeline is dark and I'm assuming the viewer uses the same background.

However, scaling up might solve it anyway if the problem is limited to the footage perimeter. How do I scale up?

Select the clip and in the Video inspector open the Transform section. You can scale it up there by 1%.

The default Viewer background is black.

Thanks Tom! I'll try that
