Why do you place -r as an input option for overlayvideo.mov?

What is this -itsoffset for?

Why use -c:v libx264 *and* -vcodec mpeg4? These are mutually exclusive,
and mpeg4 is chosen as the encoder since it was declared later.

Your main input is 30000/1001. Why are you setting the output frame rate
with -r 30?

Why do you use single pass with -b:v instead of -crf? See:

Anyway, for your main issue, your overlay needs the eof_action option:

See overlay filter docs for more info:

This version is about 6 months old which is considered geriatric. FFmpeg
development is very active.
