Variable framerate is not something Premiere is very good at.
Convert to constant framerate with Handbrake before bringing it to Premiere.
Fields should say progressive, not Upper.
Turn off Max Render/Max depth and optical flow in the export settings.
Optical flow in the timeline is only used on slomo’s.
You only use optical flow in the export settings when export framerate is different from source.
On a side note : dont call it RAW video and the RAW format is something totally different.
