8k to 4k ProRes better than 5.2k to 4k ProRes?

[Chris Jordan]

I've been wondering what's better. I am going to be shooting to the Inferno in ProRes HQ 444, and Wondered if it makes a difference (besides sensor crop) if i'm in 8K or 5k.

Well, since you are scaling down more pixels you will get a sharper image and less noise. If you are truly just recording ProRes then by all means use the "8k" setting over 5k.

Unless I'm mistaken, your Inferno - or any other recorder that takes a live SDI feed off camera - will be limited to 1080/2K at the spigot. If you meant "internal" rather than Inferno, then UHD/4K ProRes is on your menu, and in most cases higher scaling ratios are your friend. That said, electro-optical systems have "sweet spots" that can sometimes render counter intuitive results. Testing, there is no substitute.

Yes keep in mind there is no way to record (or monitor) a 4K/UHD signal to an external recorder from any of red's 8K cameras...

You can however, output a 4k signal from the Panavision DXL.

Which gives me hope that at some point DSMC2 (or maybe DSMC3) brains will output 4k as well.

That being said, displaying a 4k image, instead of a 1080p image, takes more computing power. Which means less computing power dedicated to recording, or a physically bigger, more power hungry camera.

No free lunch in the engineering world unfortunately.
