Was die Diskussion ergab
- Beginnend mit dem unteren Holm ausbalanciert durch Positionierung von Batterien und Monitor gleichermaßen auf beiden Seiten schafft eine Grundlage für dynamische Balance.
- Das Festlegen einer Drei-Sekunden-Drop Time und die Überprüfung, ob das Rig beim Herunterfallen aus der horizontalen Ausrichtung eben bleibt, ist eine praktische Validierungsmethode.
- The spin test, where a fully assembled rig is rotated to observe wobbling, indicates whether dynamic balance has been achieved.
- Once dynamic balance is established through proper initial setup, it should remain valid for different camera payloads provided the drop time is readjusted accordingly.
- Adding weight to a light camera body like the Canon 7D improves stability and allows the rig to operate closer to its designed capacity.
- Some operators advocate measuring camera center of gravity and positioning it a specific distance behind the center post, while others achieve balance through iterative adjustment without this measurement.
- Jerry Holway's method involves placing the camera three-quarters of an inch behind the measured center of gravity and adjusting only the battery block for static balance.
- The spin test method and the measured center of gravity approach produced different results in practical testing, with one operator finding wobble using the spin method but achieving a flatter result with the measured approach.
Hängt ab von
- The discussion involves disagreement about whether measuring camera center of gravity is necessary, with some operators reporting success without this step and others finding it essential.
- The effectiveness of different balancing methods may depend on specific rig configurations, battery types, monitor sizes, and their relative weights and distances from the center post.
- The Mickey device mentioned is reported to work with certain rig configurations but compatibility with the Steadicam Pilot is not confirmed.
- One operator's experience with the spin-test method on a GPI Pro sled showed pronounced wobble, contradicting claims that this method produces immediate perfect balance.
- The discussion reflects 2011 equipment and techniques, which may not apply to current gear.
