In general, it is not recommended to upgrade the process engine on existing variants. Unless you specifically want to take advantage of new adjustment tools on previously adjusted and processed images, it is not usually necessary to upgrade existing images. Capture One includes several legacy engines and the relevant one will be used with those variants.
However, if you wish to experiment to see the effect of any new tools on those images, it is recommended that you make a clone of important images and only upgrade the processing engine on the clones. This way you will be able to compare the results and retain the existing images with their adjustments using the legacy engine.
Note that User Styles and Presets created using a legacy engine may have to be fine-tuned with the new engine.
- Go to the Color tool tab.
- Select images in the Browser that require re-rendering. If multiple images are chosen, make sure the Edit Selected Variants option is enabled.
- From the Base Characteristics panel, in the Engine text field, verify that the images were rendered with an earlier engine. If so, the version will be displayed along with an Upgrade button.
- Warning! Previous adjustments will be permanently upgraded and you will not be able to retrieve them later. If unsure, press Ctrl/right-click (Mac OS/Windows) and select Clone Variant (F3/F8). Clones will be made and pre-selected for the next step (the original variants are not now selected and will be excluded from further adjustment).
- Click on the Upgrade icon to re-render the selected images. A warning dialog opens with Upgrade Engine or Cancel options.
- Click on Upgrade Engine or press Cancel to return to editing with the existing engine.
