Préparation pour le premier travail de la caméra 3D avec une plate-forme de séparation de faisceau sur Steadicam
Il y a 16 ans. Le matériel et les prix ont peut-être changé depuis.
Ce que le fil a révélé
- Les plates-formes de partage de faisceau comme le Neutron sont compactes et gérables en poids pour Steadicam fonctionnement, mais nécessitent une attention particulière à l'alignement de la caméra pendant la configuration et le transport.
- Les stéréographes manquent souvent d'expérience du service de la caméra, de sorte que l'opérateur devrait surveiller de près comment les accessoires et l'équipement sont distribués symétriquement entre les caméras pour maintenir l'équilibre.
- De larges lentilles combinées à une technique de fonctionnement lisse et stable sont essentielles dans le travail en 3D car le confort du public est compromis par le panning excessif et le mouvement de la caméra.
- Manual focusing through clamps on C-mount lenses can be time-consuming and requires frequent equipment downtime.
- The Cinedeck recording system eliminates tethering cables but has specific bootup requirements and may need additional power solutions beyond single Steadicam batteries.
- Interaxial and convergence adjustments on early Neutron prototypes required manual setup between shots rather than real-time remote control.
- A quick-release plate on the Steadicam dovetail helps maintain camera alignment when the rig is frequently handled by stereographers doing chart work and calibration.
- The Cinedeck composite output generates a slight video delay and occasionally jittery playback, but these issues were not operationally problematic.
- Three-dimensional video playback can be monitored at video village with polarized glasses to review work immediately during shooting.
Dépend de
- This discussion centers on prototype and early production versions of rigs that may have evolved since 2010.
- Specific battery power solutions mentioned were tested with Steadicam-specific power systems and may not apply to other configurations.
- Experience is limited to SI-2K cameras; behavior with larger cameras like the Sony900R or RED was acknowledged as potentially different.
- The Cinedeck bootup issue with composite video output was identified as a Windows operating system quirk rather than a hardware design problem.
- Remote motorized convergence and interaxial adjustment were still in development at the time of discussion.
