Blackmagic Design continues to dynamically evolve the Blackmagic Camera app for Android, adding new features that bring mobile video production even closer to professional workflows. With the release of Blackmagic Camera for Android 3.4, the app gains 4K HDMI video output with audio, support for WearOS camera control, REST API remote control, the ability to pause continuous recording, and new management tools for remote camera setups and proxy clips.
Blackmagic’s free app has already changed the way many creators use Android smartphones for video production. With the new update, its use becomes even more practical for live production, monitoring, remote control, mobile content creation and multi-camera workflows.
4K HDMI output with audio for professional monitoring
The most significant addition in version 3.4 is support for 4K HDMI output, along with HDMI audio output. This means that a compatible Android smartphone can now more easily connect to external displays, monitors, recorders or production setups, giving users better control over the image in real time.

For mobile filmmakers, content creators, educational studios or small production teams, this feature is of great value. The smartphone no longer functions solely as a capture device, but can be more clearly integrated into a professional monitoring workflow, with image and audio output via HDMI.
WearOS camera control for more flexible handling
The new version also adds the ability to control the camera via a companion app for WearOS. This gives users a more direct and practical way to operate, especially in cases where the phone is on a tripod, gimbal, rig, or in a place where direct access to the screen is not easy.

For solo creators, vloggers, educational setups or small productions, smartwatch control can make everyday use faster and more convenient. The operator can start or control the shot without having to touch the device, reducing the risk of shake or frame changes.
REST API remote control for more advanced workflows
Another important addition is support for remote control via REST API. This feature paves the way for more complex and automated workflows, where the Blackmagic Camera app can be integrated into custom control systems, remote production setups or third-party applications.

For integrators, developers, and professionals building more specialized production environments, the REST API is particularly important. It allows for greater control, better integration, and the ability to create more flexible solutions around Android devices that function as production cameras.
Support for Blackmagic Focus and Zoom demands
The new update also brings support for Blackmagic Focus and Zoom demands, further extending the logic of professional control through the Android app. For users who want more precise focus and zoom control on compatible setups, this addition can make shooting more controlled and closer to a traditional camera workflow.
Blackmagic Design thus continues to transfer elements from the professional camera environment to mobile devices, giving creators tools that until recently required much more specialized equipment.
