HandbrakePM has been updated to 2.3 with M1 support, it is a batch version of the compression tool handbrake
The open source video transcoder Handbrake has always been an awesome tool for compressing video, and should be in every video pros arsenal.
It’s lesser known sibling HandBrakePM, which is based on Handbrake (so uses the Handbrake CLI or command line interface) to do batch conversions. And it has been updated to include working on M1 processors. You should have Handbrake already installed for it to work.
You might not think you need this, but someday when you have a bunch of files to compress you will realize just how useful this is.
