Utilisation de la caméra Thomson Viper Filmstream sur Steadicam plates-formes
Il y a 22 ans. Le matériel et les prix ont peut-être changé depuis.
Ce que le fil a révélé
- La caméra pèse environ 6 livres avec un objectif de 3 livres, ce qui la rend relativement légère pour une caméra haute définition à cette époque.
- Les premiers prototypes utilisaient un disque dur monté sur un quai externe d'une capacité d'enregistrement d'environ 4,5 minutes, mais on s'attendait à ce que cette capacité s'étende à 10 minutes plus tard.
- L'option d'enregistrement en état solide de Grass Valley FlashPak a fourni un stockage d'enregistrement dédié conçu pour une utilisation de Steadicam et tenu environ 10 minutes de contenu HD.
- L'équilibrage de la caméra est inhabituel en raison du poids minimal de la queue, nécessitant un réglage prudent de la plate-forme.
- Power draw is approximately 5 to 9 amps, manageable with large battery packs like Dionic batteries.
- Tethered operation using dual SDI or SDI cables to an external video receiver was standard, requiring flexible BNC connectors for rig mobility.
- An L-plate adapter could be fabricated to improve weight distribution and steadicam compatibility.
- The camera produces no internal down-conversion, requiring external processing if needed.
- Operators reported that recording time limitations between takes were offset by the camera's light weight compared to other HD options available at the time.
Dépend de
- This discussion took place in 2004-2005 when the technology was newly introduced and still evolving.
- Recording capacity limitations of 4.5 to 10 minutes were a significant constraint for long takes.
- Tethered operation added cable management complexity to rigs.
- One operator's experience was from the Netherlands where some recording options were not available.
- The camera's balance characteristics were described as unusual and required operator adjustment.
- Comparison to competing systems like Genesis suggests similar battery drain concerns, though not definitively stated.
