Davinci Resolve is a proprietary video editor, color correction and compositing application.
There is a free version and a paid version (a.k.a. Studio).
For free version Install the AUR or AUR package.
For studio version install AUR or AUR package.
To run Davinci Resolve it is required to have suitable OpenGL driver and suitable OpenCL driver.
|GPU vendor||Type||Driver||OpenGL||Documentation||Works with Davinci Resolve|
|AMD / ATI||Open source||AMDGPU||No|
|Intel||Open source||Intel graphics||Yes|
|GPU Vendor||OpenCL driver||Tested version||Works with D.R. 16.0b6-1|
|Nvidia||Suitable, but working on cuda instead?|
So currently it is not possible to use intel gpu alone. If using AMD + Intel setups, you can render on intel (set it as primary in uefi setup) and install proprietary opencl driver for amd gpu.
BlackMagic Design Cards
If using DeckLink, UltraStudio or Intensity cards for video capture and playback, install Desktop Video Software withAUR package.
Application window misses title bar
It is a problem of a Linux version of D.R. There is a workaround for KDE - a window rule to force enable title bar. See 
My .mp4 clips are shown as audio clips and even its sound is not working
This problem only affects a free version of D.R. for Linux. MP4 containers are not supported, also AAC audio is not supported. To workaround, you may convert your video file to another format or purchase a studio version. Transcoding command may look like this:
ffmpeg -i input.mp4 -c:v dnxhd -profile:v dnxhr_hq -pix_fmt yuv422p -c:a pcm_s16le -f mov output.mov
To enable compatibility with high-resolution displays, set the following environment variables accordingly:
export QT_DEVICE_PIXEL_RATIO=2 export QT_AUTO_SCREEN_SCALE_FACTOR=true
Some plugins are available for Windows, but not available for Linux, so you may want to use Davinci Resolve via wine. Unfortunately, as of wine 4.13-1, it is not working. Splash screen stucks at "Looking for control surface" and in terminal there is such error message:
wine: Call from 0x7bc6c52c to unimplemented function OpenCL.dll.clReleaseDevice, aborting
