If your question is "Is FFmpeg an archiving tool like zip, 7z or tar?", the
answer is "no" - for real-world cases, you cannot get the "video in original"
back.

I don't think FFmpeg supports writing "Base Media / Version 2", only
"Base Media" is supported.

"It doesn't seem to work" is usually not a helpful problem description.

I don't understand this sentence (likely command line
and complete, uncut console output missing).

That's unrelated (and re-reading your mail, I have a strong feeling that
using MediaInfo is bad in your case because it makes you making
wrong assumptions like that you can force FFmpeg to wring "Base
Media / Version 2" files which you cannot).

Consider to describe your actual use-case, not what you believe the
technical description of your use case is.
(Ask "Why why does my media player XYZ not show the video?"
instead of "How can I write Base Media Version 2 files?")
