The Pi 4 is a serious device. 1GbE, USB 3.0. It demolishes the previous Pi devices across the board in performance. I think this is where people get confused by others using the Pi4 as a NAS or server or whatever. There is this misunderstanding of just how equipped the Pi is today.

I wouldn't even do this on my Macbook Pro with 16GB of RAM. Anything less than a workstation with gobs of RAM is just asking for a headache. Unless you're just chopping together the random video for the family once a year.
