Overview
Cache (Preview Image Size)
The preview image size (px) value determines the resolution of the previews being displayed in the Viewer of Capture One. You should always set this according to the resolution of your display, e.g. a 4K display (3840 x 2160) will perform optimally with a preview size set to 3840px:
If you set your preview size higher or lower than the resolution of your monitor, then Capture One will be slower in generating previews and displaying image adjustments. Therefore, we suggest keeping this preference to the recommended setting as shown in the drop down menu above.
Improved Previews
Experience faster and sharper image previews with Capture One Pro (16.3) - when you import images or tether, the generation of previews is now quicker, and they appear with enhanced clarity in the Viewer.
They consume less disk space, significantly reducing the storage requirements of Catalogs and Sessions. With the Preview size set to 3840 px, you can anticipate a file size reduction of 1.0 MB per image.
This option is enabled by default. To update existing previews, right-click on your images and select Regenerate Previews.
Performance Improvements in Capture One Pro (16.3):
- Up to 45% faster preview generation compared to 16.2
- Up to 41% decrease in file size
Additionally, you have an option to optimize the previews for quality (recommended) or speed:
- Optimized for Quality (Recommended): Results in the smallest proxy file size, takes a bit more time but offers efficient compression.
- Optimized for Speed: Prioritizes a quicker generation process but provides a smaller reduction in file size, sacrifices some compression efficiency.
In short, if you want the smallest file, go for quality, even if it takes a little longer. If speed matters most, choose the optimized speed option, expecting a compromize in file size.
Please Note
We have noticed a few areas where the new preview format may not perform as well as the legacy format. We are actively working on optimizing this for a future update.
For those who experience less optimal rendering (and perhaps scenarios we have not yet identified), we have included an option to Use legacy Preview Format:
To apply this change to existing images, you will need to re-generate previews. For new imports, the change will be applied automatically. As we cache the results, you may need to adjust a slider or browse back and forth to see the change.
EIP Packing (Sessions only)
Checkmark one of the options if the .EIP workflow is preferred. EIP packing can be made automatically on import or capture (Phase One digital backs only).
- Pack as EIP when importing
- Pack as EIP when capturing
Editing
Many users shoot both RAW and JPEG simultaneously. To avoid working on JPEGs and TIFFs accidentally, remove the editing option to ensure these files are viewable but not editable. The effect of selection is immediate, Capture One does not need to be relaunched. When editing is disabled, JPEG, TIFF, and PNG files can still be imported with their corresponding variants rendered and displayed in the browser and viewer. When the variants are selected, the editing tools are grayed out.
- Enable JPEG Editing
- Enable TIFF Editing
- Enable PNG Editing
When selected, new files (created during import, capture or EIP conversion) will have write permissions for everyone, not just the file owner.
- Make new files writable by everyone
Select the default processing engine for Capture One from the fly-out menu. The processing version selected will only be used by new files (created during import, capture or EIP conversion), existing files rendered with previous versions will remain unaffected. You can check the processing version used to render selected variants in the Base Characteristics tool located under the Color Tool Tab.

Metadata
When working in different, third-party applications, metadata will be stored in different ways. Choose your preferred option. If left to the default settings, the metadata entered in Capture One will be preferred to third-party metadata.
- Auto Sync Sidecar XMP (None, Load, Full Sync)
- Prefer Embedded XMP over Embedded IPTC
- Prefer Sidecar XMP over Embedded Metadata
- Synchronize IPTC Urgency with Color Tag: this toggle was introduced in Capture One 16.5.6 and allows users to enable or disable the linking of IPTC Urgency with color tags. This was previously always enabled but can now be turned off, preventing Capture One from reading or writing the IPTC Urgency field. The IPTC Urgency field is a numeric ranking system (1 to 8) that indicates the priority of an image for editorial use.
