Usually, frames with TPU or vibration absorbing rubber are not prone to the IMU
resonance issue.
• Rolling shutter eect
◆
If the rolling shutter eect appears in both the liveview and the video image, it is
usually because the propeller vibration (frequency is approximately a few hundred
Hz) is transmitted to the camera through the aircraft frame.
* Video stabilization application includes the built-in EIS function of the air unit and the video
stabilization function provided by third-party software.
Solutions
Follow the steps below.
Step 1: Troubleshoot the IMU resonance issue
1. Preparation:
a. Remove the propellers from the aircraft. Make sure that the camera is securely
mounted and the aircraft is placed stationary on the ground.
b. Then, enable RockSteady and start recording.
2. Run a test:
a. Start the motors and slowly push the throttle to the full position.
b. Observe the liveview in the goggles.
c. If the liveview is not shaking, stop the motors and end the recording. Otherwise,
check the camera and make sure it is securely mounted.
3. Check the recording:
a. Export and play the recorded video.
b. If the video image shakes, the issue is most likely caused by the resonance
between the frame and the camera IMU. In this case, try the following solutions:
1） Change the ESC PWM control frequency to 48 kHz or 96 kHz and test again.
2） If the video image still shakes, apply a softer vibration absorbing structure *
between the camera and the aircraft frame. Repeat the preceding test until
the video image does not shake.
* Due to the signicant weight dierence between DJI O4 Air Unit and DJI O4 Air Unit Pro, DJI O4
Air Unit requires a softer vibration absorbing structure to achieve the same eect as DJI O4 Air
Unit Pro.
Step 2: Troubleshoot the rolling shutter eect issue
After troubleshooting the IMU resonance issue, check whether the video image has the
rolling shutter eect.
1. Replace the propellers if there is any damage. Then, y the aircraft and start recording
with RockSteady enabled.
