Black rectangle on preview and export

Hello, my project seems to have this little black rectangle in the image. This is present on both preview and export.

Using both CRM, R3D and across three different cameras.

Any trouble shooting suggestions to fix?

Davinci Resolve Studio 18.0B Build 10

Is it there when you view source media? Does it move along with the clip if you reposition it or stays relative to frame itself? Does it respond to grading, for example offset? Go along the processing chain until you find where it is introduced.

Thanks for your reply.

It's not there when I view the source.

If I create a timeline and add the clip, it appears right away.

Doesn't respond to any grading, i.e. offset as you suggested.

Check your project burnin settings, possibly it is an enabled metadata burnin with something which doesn’t have value so you get minuscule burnin background. Since this box is everywhere and on everything and seems perfectly centered in frame it kind of hints on some kind of overlay.

I had timecode on the burn in earlier, I had since turned it off.

However, re-enabling the timecode burn in and subsequently disabling it has fixed the problem.

Thanks for the pointer, hit the nail on the head
