Intégration de la caméra Genesis avec Steadicam: puissance, câblage, montage et options d'enregistrement
Il y a 17 ans. Le matériel et les prix ont peut-être changé depuis.
Ce que le fil a révélé
- La caméra Genesis nécessite un connecteur d'alimentation Lemo de 8 broches avec des configurations de broches spécifiques permettant le fonctionnement à partir des piles 12V et 24V DC.
- Power consumption varies by configuration: approximately 15 amps when camera and SRW-1 deck operate together, dropping to around 10 amps when the deck is mounted separately on a grip or backpack.
- When operating with a detached deck, two short flexible BNC cables (approximately 6 feet each) should connect the camera to the operator's vest, with barrel connectors extending to longer cables running to the deck, keeping total cable run under 20 feet.
- The Genesis has its own run-stop cable system; compatible cables are available from multiple manufacturers including Bartech and Preston.
- The camera does not include built-in standard definition downconversion; external downconverters from various manufacturers can provide 4:3 or 16:9 standard definition output.
- The Panavision camera mount for Genesis differs from earlier models and typically includes a Steadicam-compatible PCM bracket.
- Fiber-based cable systems can transmit HD-SDI and camera control data with significantly less bulk than multiple BNC cables, though power delivery capability depends on the specific system.
- Solid State Recorder options exist but were difficult to obtain at the time of discussion, offering potential advantages in reducing cabling complexity and battery load.
- Genesis with SSR deck and full accessories can be flown at approximately 33 pounds with appropriate balance setup.
- Older lithium-ion batteries like Dionic-90s and Power Cubes can adequately power the Genesis camera.
- Some operators reported the Genesis as lighter and easier to fly than expected despite power requirements and cabling considerations.
Dépend de
- One contributor had only limited Steadicam flying experience with Genesis; recommendations should be verified by rental houses or technical specialists.
- Power draw specifications varied among sources: some reported 11 amps combined and 5-6 amps for camera alone, while others cited higher figures, suggesting variability based on configuration.
- SSR availability was uncertain at the time of discussion and described as expensive and difficult to obtain.
- Some custom fiber solutions mentioned were designed for specific individuals and were not commercially available.
- The discussion occurred in 2009; subsequent equipment developments may have changed practical requirements.
- Post expansion and balance characteristics depend on multiple variables including sled design, lens selection, and battery mounting choices.
