As per the title, I'm trying to compress MP4 files, but I'm having difficulty in getting any compression of the files so far.

From searches here, it appears that SREP should be used first followed by LZMA for final compression. SREP settings as per posts at this forum could be -a2 -m5f -l512. Unknown what setting(s) used for the LZMA compression.

How to achieve best possible compression of MP4 files please?

Using SREP, LZMA, and/or other precompressors/compressors?

And what settings should be used (in general) for compressing MP4 files?

Process MP4 files via Freearc? 7zip? or what?

Thank you.
