As an FPV pilot, stability is paramount when capturing smooth and cinematic footage. The DJI O3 Air Unit takes stability to the next level with two key features: Rocksteady and Gyroflow Stabilization.

Rocksteady Stabilization

Rocksteady is DJI’s proprietary image stabilization system that effectively minimizes vibrations and the notorious “jello effect” in videos. The result is silky-smooth footage that looks like it was captured using professional-grade stabilization equipment. Whether flying at high speeds or executing aggressive maneuvers, Rocksteady ensures that my footage remains stable and free from unwanted distortions.

Gyroflow Stabilization

While Rocksteady is the default stabilization mode, the O3 Air Unit also offers Gyroflow Stabilization. This feature can be enabled if you disable the built-in Electronic Image Stabilization (EIS). Gyroflow Stabilization is ideal for situations where I want to maintain complete control over the stabilization process. It uses the drone’s gyroscope data to stabilize the footage, offering a different level of creative control.

Storage Support

To enhance the convenience of my FPV flights, the O3 Air Unit comes with 20GB of internal storage. This means I can capture significant footage directly onto the unit without needing an external recording device. Additionally, the unit supports micro SD cards up to 256GB, providing ample storage space for extended flight sessions. The flexibility to choose between internal storage and microSD cards adds convenience and versatility to my FPV setup.

D-Cinelike Color Mode and ND Filter Compatibility

The O3 Air Unit includes the D-Cinelike color mode to enhance my aerial videography further. This mode enables precise color adjustments, allowing me to fine-tune the color palette of my footage for a more cinematic look. It’s a powerful tool for achieving the desired visual style in my FPV videos.

Additionally, the camera module of the O3 Air Unit is compatible with the DJI Avata ND Filters Set, which includes ND8, ND16, and ND32 filters. These high-quality ND filters are crafted to preserve true color details and light-dark contrast, even in varying lighting conditions.

They provide flexible aperture control and exposure selection, allowing me to capture professional-quality footage in various scenarios. With the ND filters, I can take my aerial videography to the next level, achieving stunning visuals that stand out from the crowd.
