Maybe it would be a better use of your money to get a camera that can shoot a format that doesn't require transcoding or if you have the option to attach an external recorder (Atomos Ninja, Shogun, et al.) that you can record your video into native ProRes format. Just a thought.
I have no idea what you just said. I use an iPhone 8 and a GoPro Hero 6. Can I connect a ninja to that to record in Pro Res?
Again, I'm a hobbyist.
