I'm using VideoReader to read a mp4 video, insert a few shapes and annotations, then use VideoWriter to write a new video file. The script was working fine with matlab 2023a on an intel macbook pro. After I switch to matlab 2023b on a macbook with m3 chip, the script stop working. The video geneerated shows weird shift in lines below:
I did notice if I change the file type for VideoWriter from 'MPEG-4' to 'Uncompressed AVI", it can work. But the file size is gigantic.
Can someone help please? Thank you so much!

This is a known problem in R2023b for the Apple Silicon
Possibly it only happens when you only write a single frame to the movie; I am not sure about that.
