Physical Wobble: The Aircraft Body Itself
Physical wobble is when the drone body oscillates, shakes, or rolls erratically during hover or forward flight. You see it with your eyes, not just in the footage. The drone may tip on one axis, spiral slightly, or produce a high-frequency vibration that you can feel on the controller as erratic stick feedback. Physical wobble has hardware causes (propellers, motors, ESC) and calibration causes (IMU, compass).
Camera Jello: Wavy Distortion in Video
Camera jello is a visual artifact baked into video footage: vertical lines appear to wave, straight edges curve, and the image looks almost liquid in motion. The aircraft itself may be flying smoothly. Jello is caused by vibration reaching the camera sensor, where the CMOS rolling shutter reads each row of pixels at a slightly different moment. Any vibration in the gimbal isolation system translates directly into jello in the recorded image.
Video Stabilization Artifacts
EIS (Electronic Image Stabilization) wobble appears as an unnatural waving effect in footage after stabilization is applied, particularly on tight horizontal pans or when using the vertical video mode on DJI drones. This is a software processing artifact, not a hardware problem. It is most visible at the edge of the stabilization crop area and on footage with strong geometric lines (buildings, roads). It cannot be fixed by calibrating the drone.
Quick Diagnostic Summary
| Symptom | Type | First Fix to Try |
|---|---|---|
| Drone rocks or oscillates during hover | Physical | IMU calibration indoors |
| Diagonal takeoff or one-side tilt | Physical | Inspect/replace propellers |
| High-frequency rapid shaking | Physical | Reduce P-gain (FPV) / check motor |
| Wavy, liquid-looking video | Jello | Inspect gimbal dampers |
| Waving only on pans/edges of frame | EIS artifact | Disable EIS or switch stabilization mode |
| Slow spiral during hover | Physical | Compass calibration outdoors |
