I bet those two are identical, and they are the one you are using so
far - version 4.1.9.

Look, there are four versions from some apps in the app store. One of
them identifies itself as "7", so presumably version 7.

Try
$ /volume1/@appstore/ffmpeg7/bin/ffmpeg -h

and try using this binary for your conversions.
