What the thread found

• A dual-camera 3D steadicam rig can position the second camera below the gimbal and donkey box, with the lower stage motorized to adjust for lens convergence changes during shots.
• The C-Motion system with 3D software protocol can run two focus motors in parallel to synchronize focus across both cameras.
• Managing camera-to-camera distance between zero and five degrees during a shot while maintaining rig balance presents significant engineering challenges.
• Heavier loads on a segway-mounted steadicam reduce operator control as the rig's forward-back movement influences the segway's acceleration and braking response.
• Operators reported contrasting experiences with heavy loads on segway mounts: one found heavier rigs more difficult to control, while another reported better control with heavier rigs.
• A motorized translation system can adjust camera positioning without affecting sled balance.
• Soft-mount configuration places the rig's weight closer to the operator's body and provides vestibular feedback, making it preferable to hard-mount for learning and heavy-load shots.
• The configuration can support cameras up to eight kilograms each when designed properly.

Depends on

• Experience comes from a single 3D steadicam film production with specific technical requirements.
• The motorized 3D module typically weighs four kilograms in optimized designs but can weigh ten to fifteen kilograms in unoptimized configurations.
• Operators' experiences with segway mounts and weight ratios varied, with one operator noting effects depended on personal weight and load ratio.
• The unconventional camera placement created post-production workflow complications.
• Visibility challenges exist when operating with dual cameras and mattebox equipment.
