user16900: I saw this overlay and want to reproduce it, but wonder how to do this:

It was slightly animated / synchronized with the video.

How do I reproduce this on my own videos? 
Which software is ideally suited for this task?

I currently use Adobe Premiere.
Thank you!

user6685: The tool doesn't matter in this case. 
For some kind of artistic or individual approach I'd suggest use a light table or graphics tablet. Draw the shapes 20-50 times by hand to get some nice variation and place all the drawings on top of each other like classic/traditional animation does in the old days.
Otherwise you can either use:

Any kind of pixel or vector based graphics package (Photoshop, Gimp, Affinity Designer etc.) together with Premiere or After Effects for additional tracking capabilities
A 2D Animation package which allows to draw directly on the plates 
Or even Blender's grease pencil feature  along with its tracking capabilities
