Update: thank you ALL for all your input! 💐 After some back and forth with @thorry@feddit.org , I decided to simply swap between the two capture cards whenever I need to, in order to make room for my old 3080 and call it a day. This way, I won’t have to spend any more money on this project and I retain the processing power of the 3080 when I start encoding my raw captures.

I am just about to set up my new Linux machine, which will be used to convert analog video and audio to digital video and audio. Is there any reason why I shouldn’t run the system off of a live USB stick (say, a good quality one from Sandisk), that is, without installing Linux on the hard drive and not setting up a boot partition, a system partition, and all that?
