Released on July 15, 2026, Capture One 16.8.4 is a service release that adds Album syncing and improves mask syncing in Multi-User Sessions, brings Batch Import and Sorting to Actions, and includes general bug fixes and stability improvements.

Capture One 16.8.4 is backward compatible with Sessions and Catalogs created in previous 16.8 releases. Documents from Capture One versions earlier than 16.8.0 must be upgraded to open in Capture One 16.8.4. Once upgraded, they can't be opened in older versions unless restored from backup.

Multi-User Sessions

Album syncing

Collaborators working in a Multi-User Session can now add and remove images in Albums, with those changes syncing back to the host and every other collaborator. Previously, only Smart Albums stayed in sync across everyone in a Session, so manual Album changes could quietly fall out of sync.

Improved mask syncing

Your masks now stay in sync across host and collaborator machines, without the false mismatch warnings that could appear before.

For details, see Multi-User Sessions.

Actions

Batch Import

Create multiple Actions for a Connector at once with Batch Import. Batch Import reads the specifications you've already set up in the connected service and creates a matching Action for each one, so you don't have to build them one by one. It's available for Connectors where specifications are defined in the service itself. To Batch Import, open the Create Action menu, click the drop-down arrow, select Batch Import, then choose the service and the specifications to import.

Sorting

Sorting organizes your Actions list by newest, oldest, or alphabetical order, making it easier to find the one you're looking for.

For details, see Actions (Studio for Teams and Studio for Enterprise).

System requirements

Minimum system requirements

• macOS 14 to macOS 26 (tested on macOS 14.8.7, 15.7.7 and 26.5.2)
• Windows 10 64-bit 22H2 with ESU or Windows 11 23H2 to Windows 11 26H1 (tested on Windows 10 64-bit 22H2 with ESU and Windows 11 26H1)
• Intel Core i3 (1st generation), AMD Jaguar Family CPU, Apple Silicon M1 or A18 Pro, Qualcomm Snapdragon X Elite

• Calibrated monitor with 1280×800, 24-bit resolution
• Internet is required for Capture One Live and other cloud services

Note: SSE4.2 CPU instruction set is required. Read more about this on Intel's website.

4K monitors

For optimal performance on 4K monitors, we recommend doubling the initial specifications due to the increased computational demands. Additionally, investing in a high-performance GPU with ample VRAM is highly recommended for these configurations to handle the intensive graphics processing.

Recommendations and limitations

Note: The information provided here is subject to change and unintentional errors may occur. For any queries or further clarification, please contact support at https://support.captureone.com/

General guidelines

• Browsing folders containing unsupported image files may affect application performance.
• Previews from earlier versions of Capture One may be updated, which can affect the application performance the first time images are viewed in this version.
• Using a non-US laptop keyboard might require changing some of the standard keyboard shortcuts.
• Editing images in external applications other than Adobe Photoshop might result in unexpected behavior.
• Operating under virtualization software (e.g., Parallels, Hackintosh, etc.) may cause instability. These OS configurations are not recommended.
• Some cameras provide multishot functionality by way of multiple exposures or pixel shifting. In most cases, this functionality will not be available in Capture One. However, a single RAW file from the "stack" may be viewable and editable in Capture One (as if it was a shot in single Capture mode).
• Special or auxiliary modes (like pixel shift) are only supported if noted. If the information provided is incomplete or you need specific information pertaining to support in Capture One, kindly reach out to Capture One Support at captureone.com/support.

File support

• HEIC/HEIF support: Capture One supports HEIC/HEIF 8-bit files to the extent that the operating system supports the files. If you are on a Windows computer, you might need to download the two extensions "HEVC Video Extensions" and "HEIF Image Extensions" from Microsoft to enable support in Capture One.
• Capture One DNG colors: DNG files from camera models with native support in Capture One will per default have their native Capture One colors applied. DNG files from camera models that are not natively supported in Capture One will have generic DNG Standard colors applied. Adjustments and settings from other applications embedded in DNG files are not supported.
• Other file support: TIF/JPG/PSD/PNG files that are not in RGB color space cannot be adjusted within Capture One and will be read-only. Layered Tiff and PSD files can be supported for viewing purposes only. Reprocessing the image will result in a new flattened image.
• File size limitations: The smallest supported file for viewing has a minimum side of 16 pixels. The smallest supported file for editing has a minimum side of 512 pixels. The largest supported file is 715 megapixels or 65,000 pixels on the longest edge.
