user38967: I have some smartphone video that is absurdly large for what is low-quality casual video: 100MB per minute. What is the easiest way to compress this (on Mac) using command-line or GUI, given that I don't want to optimize settings for this casual video -- just some sort of default?
I have found answers online (often quite outdated) to use  ffmpeg -i in.mp4 -vf scale=1280:720 -preset slow -crf 18 out.mp4 or the like, but I am none too sure about  what might be an acceptable default.
I also tried  ffmpeg -i in.mp4  -fs 100M out.mp4, which gives decent results -- I am interested in any further good ideas.

user12233: I'd recommend a simple GUI app, such as Smart Converter [can't remember if it's free or paid, App Store won't tell you once you own it] or Handbrake (freeware) which is a lot like ffmpeg, but without all the typing.
In both you can set up, or choose from existing, presets.
