Post screenshot export settings with left tab to output with an image.

The footage is variable framerate convert to constant framerate with Handbrake before bringing into Premiere.

Converting videos with Handbrake - YouTube

On export bump the settings bitrate is too low for 4K.

Try using Handbrake to re-encode the footage. Let us know if that helps so we can narrow down the issue
