At IBC 2025, we spoke with Craig Heffernan from Blackmagic Design about their new ProDock for the iPhone 17 Pro. Announced in tandem with Apple’s latest phone, the dock adds pro features the phone alone can’t provide: HDMI monitoring, genlock, timecode, audio in/out, external storage, and a dedicated power input. It essentially transforms the iPhone 17 into a camera that can be rigged for independent films, broadcast work, or even multi-camera productions.

Expanding iPhone video beyond USB-C

The iPhone 17 Pro can capture in 4K and ProRes RAW, but the device itself is limited to a single USB-C port. The ProDock, which we looked at in detail a few days ago, expands this into HDMI, USB-C for external drives, 3.5mm audio, genlock, and timecode, all routed through a single cable. The hardware is engineered to handle these simultaneously without the bandwidth bottlenecks that would normally occur on the phone alone. The dock manages bandwidth internally so filmmakers can run an external SSD, feed audio, output HDMI, and sync multiple cameras simultaneously without overloading the phone.

Monitoring, sync, and audio

The dock’s HDMI output is restricted to 1080p. It is not intended for high-resolution playback but instead serves as a confidence feed for framing or on-set monitoring, for example. Genlock and timecode allow several iPhones to be synchronized together or combined with Blackmagic and other cinema cameras in mixed productions.

Audio is handled through a 3.5mm input, which can be adapted to XLR through external packs. While many productions will continue recording audio separately, this input offers a straightforward way to capture scratch audio or a backup track directly to the iPhone.

Power and mounting options

The dock requires an external 12V DC supply for full functionality. Power is distributed not only to the iPhone but also to connected accessories like SSDs. Relying solely on the iPhone’s internal battery is possible, but it will quickly deplete the battery.

Mounting points on the top and bottom make it easy to integrate the dock into existing rigs. Craig said that Blackmagic has opted not to produce a custom cage, relying instead on existing solutions from companies such as SmallRig, for example. The lightweight build allows the dock to sit comfortably on gimbals or tripods, which suits mobile journalists and independent filmmakers who need compact yet professional setups.

Pricing and availability

The Blackmagic ProDock for iPhone 17 will retail for $299 / €255. It is expected to ship with the release of the iPhone 17 next week, initially through Apple Stores, and later via Blackmagic resellers. Support for both the Blackmagic Camera app and Apple’s native video software will follow shortly after the iPhone 17 release.

What do you think? Could the Pro Dock push the iPhone further into professional filmmaking, or is it still best reserved for specific use cases like mobile journalism and indie projects? Tell us your thoughts in the comments!
