Problem
A repurposed clip contains a callout that points left toward an object, but the vertical crop moves that object above the callout's original anchor.
Solution
Root Cause / Diagnostic:
Vector callouts and arrow pointers in 16:9 rely on horizontal directional geometry pointing across screen widths. When re-framed into a narrow vertical 9:16 canvas, pan-and-scan or split-screen reframing stacks subjects vertically, causing horizontal arrows to point toward empty space or off-screen boundaries while target objects sit above or below.
Actionable Fix:
1. Detach pointer callouts and tracking nulls from horizontal coordinate keyframes when duplicating edits into vertical sequences.
2. Redesign callout arrows using 90-degree vertical downward/upward vectors or circular pulse highlights centered directly on the reframed object.
3. Re-link motion tracking data to the target object's new position on the 9:16 canvas using point tracker or planar tracker nodes.
Pro Tip:
Replace directional arrows in vertical derivatives with dynamic high-contrast spotlight circles or stroke outlines directly around the subject of interest.
