Camera mounting plate with continuous T-slot and millimeter markings for precise repositioning across setups without losing position reference.
Bridge plates feature a continuous slot with 1/4"-20 and 3/8"-16 threads at 12.7mm intervals, as well as precisely milled millimeter markings. The Arri Bridge Plate BP-8 additionally has an integrated 15mm rod mount and weighs exactly 780g. O'Connor offers a carbon fiber variant with the CFF-1, weighing only 340g. Professional models like the Sachtler Touch & Go feature a quick-release mechanism with a load capacity of up to 35kg and a repeatability of ±0.1mm.
Arri developed the first bridge plate in 1982 for Alexa predecessor systems to guarantee identical framing in multi-camera productions. O'Connor revolutionized the design in 1995 with the introduction of the CFF series using carbon fibers, reducing weight by 60%. Sachtler introduced the Touch & Go system in 2003, shortening setup time between different camera positions from 3-5 minutes to under 30 seconds.
For "Mad Max: Fury Road" (2015), DoP John Seale used bridge plates for rapid camera changes during chase scenes between static and moving setups. Christopher Nolan has exclusively relied on Arri bridge plates since "The Dark Knight" (2008) for his precise shot-matching sequences. This technology allows for switching between different focal lengths within seconds without losing the exact camera position – essential for VFX plates and clean plates.
Unlike standard camera plates, the bridge plate allows for millimeter-accurate repositioning due to its longitudinal scaling. Modern motion control systems like the Technodolly replace bridge plates for complex moves, but cost 50 times more (approx. €180,000 vs. €3,600). For simple A/B camera setups, quick-release plates suffice, while for precise VFX work and shot matching, the bridge plate remains indispensable.
Ich setze Bridge Plates primär für Shot-Matching und VFX-Plates ein, wo millimetergenaue Wiederholung entscheidend ist. Das Arri BP-8-System erlaubt mir, zwischen verschiedenen Brennweiten zu wechseln und trotzdem exakt dieselbe Kameraposition zu halten - besonders wertvoll bei Clean-Plates für Compositing-Arbeiten.
Bridge Plates geben mir die kreative Freiheit, spontan zwischen verschiedenen Bildausschnitten derselben Szene zu wechseln, ohne Continuity-Probleme zu riskieren. Wenn ich merke, dass eine Totale besser funktioniert als die geplante Halbtotale, kann mein Kameramann binnen Sekunden umbauen und wir verlieren keine kostbare Drehzeit.
Eine Bridge Plate für 3.600€ amortisiert sich bereits nach zwei Drehtagen durch eingesparte Umrüstzeit - statt 15 Minuten pro Setup benötigen wir nur noch 2 Minuten. Bei 60 Setups pro Tag sparen wir 13 Stunden Crew-Zeit, was bei einer 12-köpfigen Kamera-Crew etwa 8.000€ Personalkosten entspricht.
