Proxy / Optimized Media format?

I'm just wondering what format people generally use for optimized media and why?
I've been using DNxHR LB for editing on a 24 inch monitor, and the quality seems fine. Is there any reason to use a higher quality format?
From what I can tell, color and effects are applied to the original media anyway.

There is no real need for better format.

If you intend to output the optimized media instead of the originals you would of course want to use a format at least equal to the source footage. Otherwise it doesn't matter.

However, color correction will be applied to and display the optimized media as long as "use OM media when available" is selected, and DNxHR LB will clip out-of-bounds data in the original files, which could be misleading when you color correct. You can turn OM on and off for this purpose -- edit with it on, cc with it off, for example.

When you "Deliver", you'd be outputting the original files, if the "use Optimized Media" option isn't selected on that page.

Thank you for the replies. That seems to confirm what I thought.
I hadn't thought about clipping when doing the color correcting though, so I guess I should turn off optimized media when checking my color grading.
