Ah, under Distort in Motion, the Aspect Ratio was at “50”. I switch it back to 0 and copied the clip, then selected the rest and performed a Paste > Attributes > Distort to switch all the rest to “0”.
Thank you so much! And may this solution help serve others.
By the way, after converting to ProRes, it added an extra “MOV” to my file name (not the extension). I easily fixed this with a free program called NameChanger.
Cheers
