2010Forum Cameras (Film/Video/HD)
Vorbereitung auf die erste 3D-Kameraarbeit mit einem Strahlteiler-Rig auf Steadicam
16 Jahre alt. Geräte und Preise können sich seitdem geändert haben.
Was die Diskussion ergab
- Beam Splitter Rigs wie das Neutron sind kompakt und überschaubar im Gewicht für den Steadicam-Betrieb, erfordern jedoch eine sorgfältige Kameraausrichtung während des Aufbaus und Transports.
- Stereographen haben oft keine Erfahrung in der Kameraabteilung, daher sollte der Bediener genau überwachen, wie Zubehör und Ausrüstung symmetrisch zwischen den Kameras verteilt sind, um das Gleichgewicht zu halten.
- Breite Objektive in Kombination mit glatter, stabiler Bedientechnik sind bei der 3D-Arbeit unerlässlich, da der Komfort des Publikums durch übermäßiges Schwenken und Kamerabewegungen beeinträchtigt wird.
- 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.
Hängt ab von
- 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.
