DJI Ronin 4D Video Transmitter

Product Information

Press the HOME button once to enter the menu, tap Display and then LUT File Settings under the LOOK tab. DJI Ronin 4D has been designed with an innovative industry-first active Z-axis to eliminate vertical camera shake effectively. This technology allows the operator to shoot while walking, running, or moving around dynamically, with no need to practice pacing or rely on external equipment. Videos taken in complex spaces like stairways or uneven ground are smooth without any trace of the operator’s footsteps. DJI Ronin 4D even captures wide sliding shots easily, without the need for a dolly. It did seem like a step forward in terms of the various autofocusing systems that are out there, and it’s almost certainly something that you’re going to rely on if you’re operating without a dedicated focus-puller. Especially if your manual focusing skills are as average as mine. But we’re still not in a world where professional DOP’s are going to trust an electronic system for focus. The reason being, any drop in focus on a big production could cost you a lot of money and annoy a lot of the cast and crew. DJI empowers creators with accessible and intuitive devices to capture and share the world exactly how they see it,” said Paul Pan, DJI Senior Product Line Manager. “With DJI Ronin 4D, we use the power of technology to make cinema-standard production more affordable, cinema cameras more flexible, and cinematic imaging available to a boundless array of filmmakers. DJI Ronin 4D draws on our expertise in both aerial and ground-based cinematic innovations to enable the next generation of professional content creators to amaze and inspire us.”

Log in with your DJI account. Select Ronin 4D in DJI Assistant 2 (Ronin Series), and follow the steps to activate. During the activation, do not power off or disconnect the devices. The monitor is a 5.5-inch, 1,920 by 1,080-pixel touchscreen display with 1,000 nits of brightness. It’s a perfect size for a gimbal where a big, rotatable screen is always helpful for monitoring but there needs to be a balance with how much weight it adds and just how much room it takes up. The picture quality looked good from my experience and it had the clarity to be able to discern subject sharpness by eyeballing it. What does that mean? On a typical handheld DJI stabilizer (other brands are available), the system counter-balances the camera's pan, tilt and roll movements with electronically-controlled motors. But something that isn’t properly accounted for in this set-up is the up-and-down motion that’s created by the operator when they walk, jog or run. DJI didn't stop there when bringing new tech to the Ronin 4D either. The camera system also has new O3 Pro transmission tech, which can push a 1080/60p video feed to remote monitors that are up to 20,000 feet away. This means a focus puller can tweak the focus without needing to run around next to the camera operator. Use the provided USB-A to USB-C data cable to connect the USB-C port above the storage card slot of the main body with a computer. Then, Launch DJI Assistant 2 (Ronin Series).

Build Quality and Design

On the top, there's also a 1,500-nit, 7-inch monitor that has a built-in gyro sensor, which turns the monitor into a motion controller if you fancy controlling the camera with movement. And to hoover up all of your footage, there's a 1TB SSD drive inside alongside a CFexpress Type-B slot. To create gripping, atmospheric shots, the dual-native EI of 800/5,000 and over 14 stops of dynamic range help capture scenes with rich color grades, regardless of shooting scenario. Even in complicated lighting situations, DJI Ronin 4D’s proprietary DJI Cinema Color System (DCCS) delivers natural skin tones and enables effortless tonal consistency across a project when using different cinema cameras. The camera’s built-in nine-stop physical ND filters make it easy to adjust to drastically changing lighting conditions, especially when outside on location. There's no doubt about it – the DJI Ronin 4D is an exciting entry into the world of cinema cameras. It’s bold, different and produces imagery that no other camera in this category can, or certainly not without additional third-party equipment. So the DJI Ronin 4D is a unique camera, but how good is its image quality? This is where DJI has taken another big leap forward. Using DJI’s all-new O3 Pro transmission technology, the 4D Video Transmitter outputs a 1080p/60fps feed to remote monitors with a transmission range of up to nearly 20,000 feet. It also includes AES 256-bit encryption that protects the video feed and industry-leading end-to-end low latency for a smooth, real-time monitoring experience as operators move freely about the set.

Here, things are different. There’s the option of a 6K or 8K full-frame sensor. My preference is the 6K one for a few reasons; better low light performance, smaller, more manageable file sizes, and cost.

Like Ronin 2 and Inspire 2, DJI Ronin 4D uses the TB50 Intelligent Battery, which offers up to 2.5 hours of shooting time. Even in extreme weather conditions, the TB50 battery is still reliable with the help of auto-heating technology. For certain video specifications, LiDAR waveform and the exposure waveform on the main monitor cannot be enabled while recording.
