Thank you very much.

That would be trying to fly ;-)

I'd rather suggest getting a good book or course on Unix shell, file
descriptors, redirections, etc., and come back to FFmpeg once this
aspect of the issue is no longer a problem.

For example, anybody skilled enough can tell that the reason "... 2>&1 >
freezeoutput.txt" produces an empty file is that the order of the
redirections matters.
