Trying to open an old project done in another machine graded using Colorista II. My current machine has Colorista IV installed. When I open the project, it says "Filter missing: Colorista II".
I guess one solution now would be:
1) Uninstall Colorista IV.
2) Install the Colorista II demo (assuming I can still find it on the web).
3) Grade each clip by hand in Lumetri or something, mimicking the settings in Colorista II.
4) Uninstall Colorista II.
5) Reinstall Colorista IV.
...Or I could find some way to to access the Colorista II's settings in each clip (even though the filter is missing), export them somehow and reimport them, either to Colorista IV or to Lumetri.
