In drop down menu on the left side there are two MP4 related entries:
MP4 Muxer
and
MP4v2 Muxer
What are the differences between them?
Which is more compatible? to (software) videoplayers?

Answer from LK, technology writer for techjourney.net: Differences of MP4 & MP4v2 Muxer Output Format (https://techjourney.net/differences-of-mp4-mp4v2-muxer-output-format/)
The main practical difference is that you can't use E-AC3 with the MP4v2 muxer in Avidemux.
