DaVinci Resolve

Black Magic Davinci Resolve is a program for video editing, color effects and A/V post production. For FOSS alternatives you might want to look into Shotcut and Kdenlive.

Installation

There are two versions of Black Magic Davinci Resolve on NixOS.

* davinci-resolve (the free version)
* davinci-resolve-studio (the paid version)

For Linux, Davinci Resolve Free has only partial h.264 and h.265 support due to licensing restrictions. AAC audio is also not supported in the Free version.

Drivers

DaVinci Resolve requires a GPU that supports either OpenCL 1.2 or CUDA 11.

AMD

There are multiple options to run Davinci Resolve with AMD cards, but it strongly depends on the generation of your AMD card. Also make sure to read the AMD GPU page (this wiki) and the Davinci Resolve entry on Archwiki.

AMD GPU Compatibility with DaVinci Resolve on Linux
GPU Generation	Series	DaVinci Resolve Compatibility	ROCm Support	AMDGPU Support	Rusticl Support	Vulkan Support	Confirmed
Pre-GCN & Early GCN	Radeon HD 5000/6000/7000 Series	Limited (OpenCL 1.1)	Not supported	Experimental	No	No	❌ No reports
GCN 4th Gen (Polaris)	Radeon RX 400/500 Series	Moderate (OpenCL 1.2)	Supported up to ROCm 5.6	Yes	Yes	Vulkan 1.0
GCN 5th Gen (Vega)	Radeon RX Vega Series	Moderate (OpenCL 1.2)	Supported up to ROCm 5.6	Yes	Yes	Vulkan 1.1
RDNA (Navi)	Radeon RX 5000 Series	Good (OpenCL 1.2)	Supported	Yes	Yes	Vulkan 1.1	✅ Confirmed
RDNA2 (Navi 2x)	Radeon RX 6000 Series	Good (OpenCL 1.2)	Supported	Yes	Yes	Vulkan 1.2	✅ Confirmed
RDNA3 (Navi 3x)	Radeon RX 7000 Series	Good (OpenCL 1.2)	Supported	Yes	Yes	Vulkan 1.3	✅ Confirmed

A cheap and good card to look out for are the Radeon RX Vega Series which are supported with the amdgpu driver. Better for davinci are cards with RDNA (Radeon RX 5000 or newer).

There is also the proprietary amdgpu-pro driver which has mixed results. The free drivers (amdgpu) are better.

Contrary to the Arch Wiki, DaVinci Resolve seems to work (on an RX 570) without switching to proprietary GPU drivers.

Intel

DaVinci Resolve has partial support for Intel GPUs on Linux. Audio playback works on the Fairlight page, but the video timeline does not work. To add Intel support, add the following setting to your configuration.nix:

 hardware.graphics = {
    enable = true;
    driSupport32Bit = true;
    extraPackages = with pkgs; [
        intel-compute-runtime
    ];
  };

X11 or Wayland

Davinci Resolve can run on both X11 and on Wayland.

If you want to maximize your chances you can try and start davinci in the following way to check for ROCM or Rusticl support

ROC_ENABLE_PRE_VEGA=1 RUSTICL_ENABLE=amdgpu,amdgpu-pro,radv,radeon DRI_PRIME=1 QT_QPA_PLATFORM=xcb davinci-resolve

Troubleshooting

Resolve crashes/fails to start

If it doesn't launch, and crashes when running davinci-resolve, then try running it as root.

If it didn't help, you can view the error log at ~/.local/share/DaVinciResolve/logs/ResolveDebug.txt to pinpoint the issue.

If you can spot a line similar to Cannot mix incompatible Qt library (5.15.12) with this library (5.15.2), and have configured QT options in your NixOS configuration (qt.enable = true;), try disabling them.

Cannot import video file

DaVinci Resolve's free edition does not come with H264/H265 support. You need to convert your video to a supported video format, like DNxHD/DNxHR and Cineform. you can do this with ffmpeg. With FFmpeg installed, assuming your video is called video.mp4, you can use the following command to convert:

ffmpeg -i video.mp4 -c:v dnxhd -profile:v dnxhr_hq -c:a pcm_s16le -pix_fmt yuv422p output.mov

This command will convert your video to a DNxHR video and your audio to uncompressed 16bit PCM. For 24bit PCM, use -c:a pcm_s24le instead.

You can know more about DNxHD/HR profiles with the command ffmpeg -h encoder=dnxhd

Resolve also supports Cineform and a few other formats. For Cineform encoding, use the cfhd encoder.

Unsupported GPU Processing Mode

If DaVinci Resolve shows a popup asking to review GPU configuration in preferences, and if there is no GPU detected in "Memory and GPU" in preferences, you can try the following in your configuration.nix:

 hardware.graphics = {
   enable = true;
   extraPackages = with pkgs; [
     rocmPackages.clr.icd
   ];
 };
