Camera Does Not Recognize the MOTION MOUNT

Symptom

The camera does not recognize an installed MOTION MOUNT.

Explanation

Camera firmware must be v5.1.14 or later to recognize the MOTION MOUNT. If necessary, load the latest camera firmware, then perform a hardware rediscover.

Potential Resolutions
  • Upgrade your camera firmware to v5.1.14 or later from RED Downloads at www.red.com/downloads.
  • Perform a hardware rediscover:
    1. Go to Menu > Settings > Maintenance.
    2. Select Rediscover.
    3. Select Yes on the screen that asks you to confirm the Hardware Rediscover.

      The camera turns off.

    1. Turn on the camera.

Irregular Out-of-Focus Bokeh Effects and Flare

Symptom

Footage displays irregular out-of-focus bokeh effects, distortion, or flare.

Explanation

The MOTION MOUNT may produce irregular out-of-focus bokeh effects, distortion, or flare in “ND Only” when an ND value over 4.00 stops is selected and a very wide aperture is used. For more information on bokeh asymmetry, go to Out-of-Focus Field Modification.

Potential Resolutions
  • Increase aperture to greater than T4.0.
  • Reduce the MOTION MOUNT ND value to 4.00 or less.

Double Exposures in Captured Footage

Symptom

Recorded footage displays irregular motion blur or duplicate images, also known as “ghosting”.

Explanation

The MOTION MOUNT Soft and Square shutters provide improvements in temporal aliasing and motion at frame rates up 109.98 fps, but are more effective at lower frame rates. For more information, go to Soft Shutter Angle or Square Shutter Angle.

Potential Resolutions
  • Reduce the frame rate used in the shot to below 109.98 fps and try again.
  • Ensure that you are using a recommended shutter angle.
