  • Grading ProRes HQ Quicktime

    Posted by Jake Keller on April 23, 2015 at 2:58 am

    Hi all,

    About to grade a project using a final Quicktime export and had a few questions about settings for the file I’d be working off of. I’ll be finishing at 1080p and the footage was shot in 8-bit with the a7s @ 1080p and a GoPro @ 2.7K. Is ProRes HQ overkill for the format I would receive the Quicktime in? Thanks for your help.

    Nope. This is what I would do as well.

    [Jake Keller] “Is ProRes HQ overkill for the format I would receive the Quicktime in?”

    For 1080P 8-bit, probably. Plain vanilla ProRes 422 is still a 10-bit container and will be just fine.

    If you use any tricks to try to improve the chromaticity resolution, I would render the graded media in HQ, though. Something you can try is to “smooth” the U/V vectors with a little blur in a node swapped to YUV mode.

    Thank you for the replies guys. Joseph, I’m not a very advanced Resolve user, where in the Color tab can I swap the node to YUV?

    One other question regarding bit rates, this time from the C300 with no external recorder. Cutting on 422 transcodes at the moment and not finishing on a Quicktime. Should I reingest to HQ media for the online?

    each node can be set up to behave differently: I set up a unque first node in the process tree, right-click on that node and a conversion dialog will be part of the options. Shut off the individually checkmarked process applied to luminance, so that any applied filter, whether blur, sharpening, or whatever will only affect the chroma channels, leaving the luminance channel unchanged. this is an old trick usually applied to improve chroma keying.

    working with HQ in “online” won’t make any qualitative difference, conveting the C300 to an intra codec may help with other processes, though.
