Operating a Steadicam with a parallel 3D HD camera rig
16 years old. Gear and prices may have changed since.
What the thread found
- In parallel camera rigs for 3D, the edges of the frame are typically removed during post-production when adjusting convergence, so framing should be kept loose to avoid important content being cropped.
- Edge violations occur in 3D when objects in negative space touch frame borders, so subjects should be kept away from the top and sides of the frame.
- Slow pans and smooth movements are essential for 3D Steadicam work to avoid excessive depth perception issues.
- When operating 3D rigs with a sled monitor connected to only one camera, the operator will not see the frame from the other camera, but this is manageable since both camera views are typically very similar.
- Centering the subject in the frame provides more post-production flexibility for adjusting the screen plane position and can help avoid edge violations.
- The Steadicam operator should maintain level and stable operation while delivering the framing requested by the director of photography, with the stereographer responsible for addressing any 3D-specific technical issues.
Depends on
- Advice applies specifically to parallel camera rigs where convergence is adjusted in post-production.
- The operator had no prior practical experience testing movement speeds and types for 3D acquisition.
- This was for a live performance with no rehearsals or ability to reset shots.
- Operating weight was limited by a Flyer LE Steadicam rig.
