GlobalAlign
Global stereo pair alignment
Aligns left and right stereo views using translation and rotation to reduce global vertical or rotational mismatch.

DaVinci Resolve · Fusion
GlobalAlign is a stereo-preparation tool for correcting broad alignment errors before disparity, convergence or creative stereo processing.
Overview
What GlobalAlign does
GlobalAlign is a stereo-preparation tool for correcting broad alignment errors before disparity, convergence or creative stereo processing.
Think of the left and right eye images as two transparent sheets: GlobalAlign shifts and rotates them until major features sit on compatible scanlines.

Practical setup
A reliable workflow
- 1
Load the stereo pair.
- 2
Fix vertical mismatch before horizontal creative convergence.
- 3
Choose balance behavior.
- 4
Correct rotation only if needed.
- 5
Inspect edges and fine detail in both eyes.

Troubleshooting
Common mistakes
Pushing GlobalAlign farther than the source resolution can support
Animating several GlobalAlign controls that fight each other instead of choosing one clear primary control
Judging GlobalAlign edge quality only in a proxy or reduced-resolution Viewer
Production notes
Practical tips
Keep the main GlobalAlign transform logic together instead of scattering equivalent adjustments across several nodes.
After a strong GlobalAlign deformation, inspect image edges and alpha for stretching or resampling artifacts.
Preview animated GlobalAlign work at normal playback speed as well as frame by frame.
