quick-look-plugins VS Mailspring-Libre

Welp you need to add your own QL-plugin for these non-standard files. You can start from this list of open source QL-plugins: https://github.com/sindresorhus/quick-look-plugins

The most robust way would probably be to find a new QuickLook extension for videos that replaces Apple's default https://github.com/sindresorhus/quick-look-plugins

Nice! Btw, while we're talking about Quick Look, there's a paid app called Peek on the App Store that is fantastic and worth every penny. It adds QL to hundreds of file formats. And here's a list of PL plug ins on GitHub. It has the Better Zip one, and a super cool one for peeking into app packages called Apparency. Can you tell I like Quick Look? lol

There's this https://github.com/sindresorhus/quick-look-plugins and https://findergg.com

If you know about brew you can also find a bunch of extra quicklook plugins: https://github.com/sindresorhus/quick-look-plugins

Works on and off for some things (video previews for example) but overall worth a quick "brew install" in my opinion.

This is probably the closest alternative: https://github.com/sindresorhus/quick-look-plugins

Since I wanted to try quick look plugins I had to turn it off because I'm using Catalina. Now I just don't know if it turn on alone or if I have to turn it on myself

If you want to give it a try I recommend you to use libre version since the telemetry has been removed in that one: https://github.com/notpushkin/Mailspring-Libre

Seconding the Mailspring recommendation, but be aware that it requires a Mailspring ID. There’s some progress, though, with a telemetry-free fork[1] (that’s the version I’m using right now) and plans to make the ID optional in the official client [2].

N. B. Please note that Mailspring Libre build isn't fully open source right now: the sync engine, MailSync, is proprietary, and while we're working on replacing it, it probably won't happen anytime soon. By downloading Mailspring Libre build, you accept the MailSync license (which doesn't affect you as a regular user).

I've just started using Mailspring-Libre. I've only used it for basic scenarios so far but I have no complaints. I can't speak for power-user features yet.
