Export edit to ProRes 4K in real time

[Anaconda_]

Hey all,

I'm a proud new owner of an Atomos recorder and I had a sudden thought today. I'm sure there are reasons this is not a good idea, but in a pinch would the following experiment wield passable results?

Let's say I've made a 20 minute edit of some 4K footage shot through the Atomos. Everything's cut, graded and ready for export. Filmed at 4K ProRes 422 and cut in a sequence that matches those settings.

Is there anything 'wrong' with plugging the Atomos into the computer via HDMI, setting it up as a reference monitor, pressing record on it and playing back your sequence. The end result will be a ProRes file of your edit - pretty neat right?

Of course, that's assuming you're computer can play back at 100% without skipping any frames or having general playback issues.

Unless you use a proper video output card (like a  Deck Link), you'll merely output 8bit video in RGB. On top of that, your NLE may reduce image detail (if, as you wrote, it doesn't skip frames) for real-time playback.

That's what I was thinking, but it could still be useful for draft renders, providing the playback is smooth at least.
