The vast majority of our videos are captured on second hand 10+ year old cameras.
There are a few newer cameras in the mix, but they're significantly less common and frankly less useful.
We take the footage from those 10 year old cameras and we catalog it in nextcloud and it syncs to everyone who is involved in production.
Then we edit in kdenlive.
Audio is recorded, as needed, in ardor or audacity, and edited in the same place (or it's recorded on purpose built hardware rescued from the digital landfill and edited in ardor, audacity, or directly in kdenlive.)
Most of our editing is also done on second hand/landfill rescue computers. Most of our programming is edited and rendered at 720p or lower because that makes it cheaper and easier to work with on old hardware.
Everything lives on servers running debian (often configured with yunohost, because I'm lazy and I shouldn't have to maintain my own software.)
