Vibrations in Alexa camera footage when mounted on Steadicam rigs

What the thread found

  • Vibrations visible in rushes can result from improper camera mounting, specifically when the back pin locking mechanism is not secured.
  • The mounting plate and wedge used between camera and rig significantly affect vibration issues, with proper Steadicam-specific plates and wedges being critical for eliminating the problem.
  • Operators commonly experience better results using stock professional dovetails and dedicated Alexa plates rather than generic mounting solutions.
  • Operators often choose to supply their own mounting plates and wedges as part of their personal gear package to ensure proper setup and avoid relying on rental company equipment.
  • Vibration issues can occur during focus adjustment operations when using inadequate mounting hardware.
  • Proper mounting includes both a Steadicam-specific plate at the bottom and a secondary plate at the top for accessory mounting.

Depends on

  • The discussion involves specific equipment from a rental company that may vary by location and facility.
  • One participant mentioned a tutorial by another operator but did not provide detailed technical specifications about the solution.
  • The thread does not include measurements of vibration frequency or detailed analysis of the mechanical cause.
