Seriously, I have a VCR and various other audio/video equipment(Most involving cathode ray tubes or tape) and I like to record Gacha and SMG4 onto VHS tapes for later watching at random times.
Yes, (This is just a joke, an exaggeration). You could do that, but it reduces the resolution of the video. You could use an open-source video editor, like the one I use.(Shotcut, on a linux machine.) It doesn't have any kind of watermark.
