Eliminating side-to-side sway in stabilizer rig footage

What the thread found
- Side-to-side sway in stabilizer footage is typically caused by improper alignment at the arm-to-vest connection rather than dynamic balance issues.
- The vest-to-arm junction must be adjusted so the rig does not drift sideways when released; if it drifts, the arm should be tilted to counteract that drift direction.
- Operator technique significantly contributes to sway through body movement and footwork; walking with a side-to-side swing in either the legs or upper body will transfer to the rig.
- A properly balanced and adjusted rig should float vertically without being held and can be operated with minimal hand contact.
- Vest tightness and stability are critical; a loose or shifting vest will cause the rig to sway with each step.
- Increasing the drop time to four seconds or longer can reduce swaying in bottom-heavy rigs.
- Gripping the post too tightly causes overcompensation and introduces unwanted movement.
Depends on
- The advice applies to stabilizer rigs similar to the Glidcam V-16 design.
- Success requires the rig to be capable of static balance adjustment.
- No specific measurements or adjustment procedures beyond general alignment principles are provided.
- The distinction between dynamic and static balance problems was debated among participants.
