Unusable image
With the wrong Input Color Space, your log image appears flat, washed out and lacking contrast. Invisible in the pipeline without prior manual correction.

MetaGrade
DaVinci Resolve does not always recognise the real Color Space of your clips. MetaGrade detects it automatically, validates uncertain cases visually, then prepares your CST workflow.
The problem
Why Resolve does not recognise your log clips
This is not a DaVinci Resolve bug. Manufacturers such as Canon, Sony, DJI, GoPro, Apple, Panasonic, Fujifilm and Nikon do not always write or expose the Color Space and Gamma in their file metadata. Resolve then applies an incorrect default value.
⚙
Manual correction on every clip
In DaVinci YRGB Color Managed mode, you have to correct the ICS in each clip’s attributes. In YRGB mode with CST nodes, you manually set every CST-In node.
📁
Missing or hidden metadata
Manufacturers may encode this information in proprietary binary data, omit it entirely, or write it with names different from those expected by Resolve.

How it works
The 3 steps of MetaGrade
MetaGrade integrates directly into DaVinci Resolve Studio through the official Python API. No modification of your source files.
Automatic detection
Media Pool scan
MetaGrade analyses all clips in your timeline or Media Pool. It identifies clips incorrectly recognised by Resolve — Rec.709-A, Rec.709 (Scene), Same as Timeline, Project — and cross-checks all available metadata to determine the real Color Space and Gamma.
Visual confirmation
LUT Viewer for uncertain cases
For clips where metadata is insufficient or missing (transcode, proxy, export without tags), MetaGrade opens a side-by-side viewer. You compare the source image with several monitoring LUTs to confirm the correct Input Color Space before any writing.
Automatic CST creation
Automatic CST-In / CST-Out nodes
Once confirmed, MetaGrade automatically creates CST-In and CST-Out nodes for all your clips directly in the Color page. DaVinci YRGB mode only.

Frequently asked questions
FAQ
Why does Resolve display Rec.709-A on my log clips?
Manufacturers do not systematically write Color Space information into their files. Resolve applies a default value. This is not a bug — it is missing information at the source.
Does MetaGrade work with the free version of Resolve?
No. MetaGrade uses the official Python API of DaVinci Resolve, available only in the Studio version.
Is it already available?
Not publicly. This page is proof of work and an entry point for future beta testers. The notification form is already available now.
Does MetaGrade modify my source files?
No. MetaGrade writes only into clip attributes inside the Resolve project. Your source files remain untouched.
CST or Color Managed — does MetaGrade support both?
Yes. Step 1 (ICS detection and writing) works for both modes. Step 3 (automatic CST node creation) is specific to DaVinci YRGB mode.
Which operating systems are supported?
Windows and macOS, with DaVinci Resolve Studio 18 minimum. Tested on Resolve 20 — Resolve 21 compatibility is currently being checked post-NAB 2026.

Help improve detection
I need real-world cases
MetaGrade is only as precise as the cases it has been tested on. If you have clips that DaVinci Resolve does not recognise correctly, your contribution can make a real difference.
- Native camera files — no transcode, no proxy
- 5 to 15 seconds is enough
- Canon, Sony, DJI, GoPro, iPhone, Panasonic, Fujifilm, Nikon, Leica, Samsung or others
- If possible, indicate: camera model, codec, known gamma/gamut
