I just purchased Video Enhance AI a couple of days ago and was trying it on some old video clips. Let me warn people out there that certain combinations of factors could result in REALLY LENGTHY processing times!
I grabbed (in hindsight, a poor choice) an old video clip shot at 1280x720, 60fps. I selected the “Artemis Medium Quality” option and upscaled to 4K UHD just for fun. My computer is a Dell XPS notebook with an nVidia GTX 1050 GPU–not the strongest on the block.
Even though the clip was only 31 seconds long, it took about 3 hours to render! By comparison, upgrading to HD only took about 45 minutes.
I’m not going to bash VEAI, as it worked as expected. At least it didn’t crash. I set my “Max VRAM Usage” to Medium/Low, as per Topaz’s recommendation.
Back of the napkin calculations, this would take nearly 2 days to convert 10 minutes of footage…
My takeaways: Don’t bother with 60fps clips. Don’t upscale to 4K if you don’t need it (I don’t even have a 4K display anyway). I’m stuck with my existing GPU since it’s a notebook. So it is what it is I guess.
