Thank you so much. This solved my problem. I was tearing my hair out because I normally work in HD where the Ken Burns effect renders perfectly, but my SD project rendered shakily and I was running out of time.

Not an expert, but I have found that sometimes when I manipulate the angle of one of my clips prior to making a multiclip, I get the “UNRENDERED” effect on all the unmanipulated angles. So I rather edit the whole thing and then manipulate each clip used from that angle afterwards, by copying the settings once and pasting its attributes into the other clips.
