I’m very frustrated about problems doing this! I’ve seen many posts about importing, editing, & exporting iPhone HDR media for desktop systems (I’m on a PC, & have Resolve Studio for it) & now we’re seeing the same issues for the iPad version.
I should start out saying we shouldn’t have to add a bunch of nodes, do color transforms, & add a curve! Or, like on my PC, where I’d have to add a DeckLink card & second calibrated HDR monitor to do HDR.
I simply want to import an iPhone HDR video file & have the imported image look exactly the same in the resolve viewer as it does on the iPad photos page. Then I want to be able to make some minor color & level changes, & export in the same HDR format as the import. Then I expect to view the edited image on the iPad, & it should match the changes I saw on the Resolve viewer.
I’ve been able to set up DaVinci YRGB Color Managed settings & have tested them by importing an HDR clip, then NOT making any adjustments, & then exporting the clip as HDR. The rendered clip looks pretty much the same as the imported clip, & has the same HDR indicator in the upper left side of the video during playback as the original.
The problem is what I see in the Resolve viewer doesn’t look anything like to imported/exported clip, making it almost impossible to know what I’d be tweaking on the color page. The image I see in the viewer has blown highlights, & is higher contrast than what was imported. It’s as if the display color space is out of wack. I’ve tried adding one of the built-in LUTS as a display monitor lookup table, but none of them seems right.
Since EVERY iPad used to edit video using DaVinci Resolve is also capable of shooting in Dolby Vision HDR, as is any modern iPhone, it seems that Blackmagic Design should come up with a simplified fix for this issue. Like a one-button function to select HDR —> edit —> HDR. Maybe also HDR —> edit —> SDR.
And the viewer should be “what you see is what you get.” While the simplified iPad version of iMovie can’t really make color adjustments, it allows pasting together clips where the output matches the input — basically a closed-loop Apple solution. I’d like to see Resolve have the same closed-loop solution, but with infinitely better editing & color-correction capabilities.
I’ll be purchasing the Studio version of Resolve for iPad, but only after I see this is working.
