I have found that VEAI has several short-comings. I listed them out here.
I think the one thing I don’t mention in there is that to increase frame rate, the best model is Chronos - SloMo. To get 60 fps from a standard 24~fps source, you have to run it at 300% into an image folder. Then convert that back to a movie with something like ffmpeg. (I can give you a sample command/batch file script to get you started if you want to use this approach.)
It’s a shame really. The Chronos Fast model is suppose to streamline the process, but it adds huge blurry patches over trees and other things quite often.
Also, in that post, I mention how mp4 format loses quality at any CRF. That is true for my computer monitor, but I can’t see the artifacts on my TV screen. I have a nice monitor, but it’s far from being accurate enough for professional movie editing and such. My TV on the other hand, is the cheapest thing money can buy. Anyway, there’s a chance you won’t even be able to notice the artifacts.
