Suppose you want to add extra notes by annotating the original PDF slides then inserting the modified frames at the appropriate locations in the video stream. The frame input JPEGs will need to be scaled to the same dimensions as the video input, otherwise you get a resolution mismatch error.

If it’s nothing but frame inputs, then no problem.

This will get the video stream dimensions:

% ffprobe -loglevel error -select_streams v -show_entries stream=width,height -print_format default=noprint_wrappers=1 INFO321_2016-09-16.mov
width=1024
height=768
