The Edit Colour Space option from the Timeline contextual menu allows you to modify the Pre-processing options of all the currently selected sources. (This tool does not affect Sequences, only sources.)

- Tool Mode button
- Choose whether to convert your media into a different colour space or only tag them.
- Tagged Colour Space menu
- Choose the colour space to tag your media with (this does not modify pixel values, but it does affect how viewports display your media).
- Input Colour Space menu
- Select the source colour space of your media. "From Source" uses the the currently tagged colour space, which allows you to easily convert a set of clips in various colour spaces to a common working space.
- Working Colour Space menu
- Select the destination colour space of your media. Set the Working Space first in order to filter the list of Input Colour Spaces to only show the compatible options. "From Project" takes the value from the Colour Management Preferences.
- Get Colour Space From Selection button
- The tool starts with the colour space setting that was last used. Click this button to initialize with the colour space of your primary selection.
