Is it Worth it to Compress Media with xz, bzip2, gz or zip?

In this video I compare command line compression utilities on macOS. I installed many of the utilities using Macports.

I compare compression utilities here: https://youtu.be/PCd7FcZ7h6A

I have a video on installing Macports here:https://youtu.be/N22Ic6ZRPXI

I used these compression utilities:
pixz – multithreaded pixz
lbzip2 – multithreaded bzip2
pigz – multithreaded gzip
zip – standard zip

macOS Command Line Compression Utility Comparison (7z, xz, bz2, gz, lz4, ha, zip)

In this video I compare command line compression utilities on macOS. I installed many of the utilities using Macports. I have a video on installing Macports here:https://youtu.be/N22Ic6ZRPXI

I used these compression utilities:
7z – 7zip
xz – lzma compression
7z – 7zip with “ultra” settings
bzip2 – Burrows–Wheeler algorithm
lzma – lzma compression
pixz – multithreaded pixz
ha – based on arithmetic/Markov coder
lbzip2 – multithreaded bzip2
lz4 – LZ77 compressor
pbzip3 – multithreaded bzip2
pigz – multithreaded gzip
zip – standard zip
