I’ve done it before, turns out it’s a very tedious job. First, you have to upscale it to 480p, then you convert the video to 720p, upscale that to 720p, then convert the video to 1080p, upscale it to 1080p, then so on.
I’ve done it before, it’s a long staking process, I think I would be fine with doing it because, my computer can handle that force. I think. Last time, it took 28hrs, and I thought it was a waste because, there were certain artifacts that I wasn’t particularly fond w/ seeing.
