11 Inspirasign.com Inherent Challenges
Hardware Needs (beyond mono projects) Stereo capable computer monitor
passive recommended (especially with After Effects) 2x+ High speed storage
most shots will require compositing fixes = more
storage Software Needs
Compositing Software (required) After Effects, Nuke, Fusion, etc.
Additional software (optional / not covered)
Mettle Skybox Studio Dashwood 3D Algorithmic plugins

Stitching complications (beyond mono) Auto-stitch can lead to unwanted stereo depth artifacts Additional stereo alignment between perspectives
camera holders manufacturing errors
lens aberrations etc
Quality complications Additional image transformations
1 or 2 for mono 3 or 4 for stereo
stitch, S3D alignment, stitch adjust, stereo blending

Assumptions Kolor Autopano Video (& Giga) and After Effects
www.kolor.com www.adobe.com/AfterEffects
Kolor
Proceed as normal: import, sync, stitch frame(s) Giga - edit stitch in Giga
Refine left as normal Right cameras
Delete all auto-solves Solve each to its left camera ONLY
Resolves some vertical alignment issues Solve for distant points only
Sets convergence in the distance Reduces manual stereo adjustments to blend
angles
