Capture steady, high-definition footage in virtually any scenario with the Osmo Action 4 Camera from DJI. The Osmo Action 4 features many of the same features as its predecessor, like dual screens, RockSteady and HorizonSteady stabilization systems, and a waterproof camera body. The standard combo pairs the Osmo Action 4 with a high-capacity battery, quick release adapter mount, a protective frame, a curbed adhesive base, a locking screw, a lens hood, and a USB-C charging cable.
High-Definition Video with Wide Dynamic Range
The camera features a 1/1.3" sensor to record up to UHD 4K120 video and capture experiences in dynamic, smooth detail. A super-wide 155° FOV ensures all the action is in frame. 10-bit D-Log M color mode provides you with over one billion colors and a wider dynamic range for vivid footage.
Color Temperature Calibration
The Action 4's color temperature sensor intelligently adjusts white balance and auto-exposure for highly accurate colors, even in complex lighting environments like when scuba or free diving deep below the surface. Sync with the DJI Mimo app for improved detail rendering underwater.
RockSteady 3.0
An intelligent stabilization algorithm eliminates camera shake in all directions to ensure your high-adrenaline mountain biking or skiing shots maintain smooth movements. It supports use while recording at up to 4K120, providing a stable and immersive first-person perspective.
HorizonSteady and HorizonBalancing
This smart stabilization feature helps to eliminate camera shake in all directions, and even horizontally corrects tilt at any angle in 2.7K60 video. That means footage can remain horizontally level, even through heavy bumps and 360° rotations. In addition, you can activate HorizonBalancing, which corrects the tilt horizontally within ±45° and supports recording stable 4K60 videos.
Efficient Shooting Configurations
The magnetic quick release design of the Action 4 allows you to easily switch things up when needed. Detach and switch between different mounts and accessories. The horizontal-vertical protective frame lets you natively shoot vertical video for social media platforms.
Custom Modes and Quick-Switch Button
Use features like SnapShot to ensure you never miss a moment. Save frequently used settings to the five built-in shortcuts to switch modes on the fly using the quick-switch button or voice prompts.
Voice Prompt and Voice Control
Intuitive control, even if you can't see the screens. Short press the Quick Switch button, and the camera will voice broadcast the current shooting mode. Even if the camera is installed on a helmet or other hard-to-see location, you can accurately select the required mode and be confident you'll never miss the moment you want to record. You can even add up to five sets of custom parameters to the shooting mode list. Remotely control your camera with just your voice. Ideal for scenarios where your hands are busy, the Action 4 recognizes voice commands with a high recognition rate, letting you stay locked into the moment.
Dual Touchscreens
The 1.4" front screen is convenient for vlogging and framing selfies and supports commonly used touch control functions. No more turning the camera around for parameter adjustments, mode switching, or video playback. When the camera is switched between horizontal and vertical orientations, the user interface adapts accordingly. The touchscreens are also sensitive enough to be operated easily with wet hands.
AI Selfie Stick Removal
Use the upgraded InvisiStick function with the DJI Mimo app to fully eliminate the selfie stick from your shots to maintain your camera's POV without interference from your mounting equipment.
Wi-Fi Live Streaming
Live stream directly from your Action 4 using the built-in dual-band Wi-Fi or your phone's hotspot. Choose your preferred platform and resolution to connect anywhere and record your footage.
Onboard Audio Interface
Three built-in omnidirectional microphones record accurate and clear sound. A hidden microphone at the bottom of the Action 4 suppresses wind noise for windy or fast-moving scenarios. Connect the separately available DJI Mic for a portable, easy-to-mount audio solution with a transmission distance of 820'. The camera can connect to other external microphones using an optional USB-C to 3.5mm cable.
Waterproof
The camera body can be fully submerged up to 59', enhancing your underwater adventures without the need for additional accessories.
Long Battery Life with Fast Charge
Continuously record for 2.6 hours with the 1770mAh high-capacity battery capable of operating in temperatures as low as -4°F. Fast charging technology allows you to power up the battery 80% in just 18 minutes.
Timecode Sync
Built-in timecode in the Action 4 allows you to easily synchronize footage in multi-camera shooting scenarios.
LightCut Video Editor
The LightCut video editor app is thoroughly optimized for use with the Action 4. It can automatically select clips and intelligently match them with exclusive templates to generate ready-to-share video edits. It supports a direct connection with the Action 4 for quick, convenient footage previews. After shooting, simply let the AI select your highlight moments and generate 4K HD videos. Choose from a number of fun templates designed for fast-paced footage. Whether it's biking, snowboarding, or diving, epic little edits are right at your fingertips.
