Hi all, I’m encountering an issue when exporting a video via Media Encoder, where certain sections of the exported video appear as a black, pixelated outline of the image. Please see the attached screenshots (Export Issue 01 and Export Issue 02) for reference. The issue is also visible during the render process in Media Encoder itself (screenshot attached). I’ve completed three exports so far. Each export reproduced the issue, although the affected sections were not exactly the same each time. I've only seen this problem occur during export in Media Encoder. The clips play correctly in the Premiere timeline and also appear fine when viewed in DaVinci Resolve and REDCINE-X.

UPDATE 3

The issue is now present in both HEVC and H.264 versions when exported from PP and ME.

UPDATE 2

With further testing, I initally found that with the removal of the text layers the issue did not occur when exporting with either HEVC or H.264 in both PP and ME.

With a computer restart, I have successfully managed to export a HEVC version in ME with active text layers without the issue presenting itself.
