Problem
A slider move crosses a floor seam, creating a visible bump that cannot be hidden by the intended slow movement.
Solution
Root Cause / Diagnostic:
Floor transition seams or uneven tile joints introduce vertical displacement into slider tripod feet or track rails. As the heavy camera carriage glides across the joint, the abrupt tilt deflection registers as an obvious shudder in the footage.
Actionable Fix:
1. Place rigid rubber track shims or wooden wedges beneath the slider support legs to level out floor seams.
2. Support the slider rail using two matching light stands or tripods positioned at both track ends rather than a single center mount.
3. Slide the carriage slowly by hand across the seam while viewing focus peaking; confirm seamless optical travel across the full stroke.
Pro Tip:
Position your slider endpoints so the camera accelerates and decelerates completely within a single seamless floor section.
