Colour management
Lumit composites in scene-linear Rec. 709, in floating point, whatever your footage arrived in.
Without a configuration Lumit reads what footage files contain and shows the working space encoded to sRGB. An OpenColorIO configuration is for when that is not enough.
Choose a configuration
Section titled “Choose a configuration”File ▸ Project settings… ▸ Colour holds one row, Configuration, with Choose… and Clear beside it.
Under the row explains what happened, what was loaded, or why the configuration could not be used.
Below it, Working space states what the arithmetic runs in.
The configuration is a property of the project, saved in the .lum. A
missing or unusable configuration never stops a project opening: the preview falls back to
the built-in handling and every assigned colour-space name is kept.
Say what a footage item arrived in
Section titled “Say what a footage item arrived in”Right-click a footage row in the Project panel, choose Interpret footage… and open the Colour tab.
- As the file says is the default.
- The rest are the configuration’s own colour-space names. Pick the one the footage was shot or graded in. A space Lumit can’t read footage from is greyed out, with the reason on hover.
Look at it through a view
Section titled “Look at it through a view”The Viewer bar carries a colour-pipeline picker. What it reads is the current view/face.
| Face | Means |
|---|---|
| Linear → sRGB | The built-in transform. |
| view — display | A view out of the configuration, on one of its displays. |
| Config not in force | The project names a configuration that cannot be used; the built-in transform is used. |
Open it and the built-in transform is the first row, then one heading per display. Tone mapping sits at the foot, if enabled in Settings.
The Viewer’s exposure and tone mapping settings never reach an export; while either is engaged the badge says preview. These are both solely for helping viewing while compositing.
Writing it out
Section titled “Writing it out”The export dialogue’s Colour section gains the configuration’s spaces in its Colour space list, under a From the configuration heading. Managed by reads the configuration’s path.
- A file written through the configuration’s transform is left untagged.
- An export naming a space this build cannot transform to is refused.
