At the heart of FilmKit is a new color workflow; creators can now import custom .cube LUTs and choose whether to preview a look in the viewfinder (without affecting the recording) or burn the LUT into the deliverable. This same approach extends to HDMI inputs when using Atomos Ninja Phone, allowing Mavis Camera to preview, or capture, LUT-applied footage from a DSLR or mirrorless camera, as well as the iPhone’s internal camera.

For faster creative results, Film Kit also introduces a set of built-in filter LUTs, including Bleach Bypass, Bunny, Cinematic, IR, Monochrome, and Vintage, all designed to give shots a filmic character with minimal setup. When a production needs to move quickly from capture to delivery, these looks can be recorded and carried through into downstream workflows such as live streaming or NDI.

To help simplify color management further, Mavis Camera v7.4 introduces MLUTs (MavisLUTs) - a new format that can bundle multiple traditional LUTs and associated metadata into a single file.  MLUTs are designed to help teams organize looks more easily, especially when working across different color spaces.

FilmKit also adds OpenGate capture, giving creators the freedom to reframe and deliver to different aspect ratios from a single take. Mavis Camera provides two Open Gate modes: one is designed for Apple Log workflows, and one for Rec.709 that can capture above 4K resolution on supported devices. AppleLog2 is also now supported, reflecting the direction of Apple’s own pro capture workflows.

Beyond capture and color, v7.4 strengthens its cloud support with free ATOMOSphere Camera to Cloud integration, providing progressive uploading to the Atomos ecosystem for review, sharing, and collaboration.

A number of smaller refinements round out the release, including new white balance presets for faster setup, improved shutter-angle selection that snaps to common values (making standards like 180° easier to land reliably), refreshed translations (now fully supporting French, Spanish, Chinese, German, as well as English), and a wide set of bug fixes and performance improvements.
