Good morning, John!
I've got some ideas for you. At the moment, Rush does not allow for us to import LUTs. The closest we can get to that feature is by opening the "Color" panel on the right side of the software and using the "Edit" tab to make adjustments. Once you're happy with your image, you can click the "..." in the top right of the "Edit" panel to save these adjustments as a preset that you can apply to any footage.
However, Rush projects are compatible with Premiere Pro and if you would rather use LUTs within that software, your Rush project can be opened by selecting "Open Premiere Rush Project..." on the lefthand side of the Premiere Pro welcome screen. Once you're in Premiere, you can import as many LUTs as your heart desires.
Oh, and here's a page with some info about correcting and grading GoPro ProTune footage. Edit and correct GoPro video |
Let me know if there's anything else I can do for you!
Is there any plans on allowing Luts to be imported into Premier Rush?
Maybe someday! I'll bring it up with the engineers who build the app.
We file all of our feature requests here: Premiere Rush: Hot (1214 ideas) – Adobe video & audio apps
Our dev team checks that page regularly to see what users want/need. Looks like some users have already submitted requests for custom LUTs, go give them an upvote!
