MOTION MOUNT OPERATION GUIDE

The DSMC

RED Motion Mount™ is a revolutionary and adjustable lens mount system for your DSMC. By

integrating a global shutter, temporal anti-aliasing soft shutter, and variable neutral density (ND) system into a

single lens mount, the Motion Mount delivers on-the-fly shutter adjustments to reduce motion blur and temporal

aliasing. The ND filter also includes a linear polarizer and IR filter for improved image color and contrast.

NOTE: HDRx

is not available while the Motion Mount is installed.

VARIABLE ND FILTER

The electronic variable ND filter provides an optical density range of 0.48 to 1.20 (1.60 to 4.00 stops) when

the Motion Mount soft or square shutters are enabled, or an optical density range of 0.48 to 2.40 (1.60 to 8.00

stops) when “ND Only” mode is selected. You can quickly adjust the ND value through the DSMC touchscreen

interface or user keys, eliminating the need to physically change filters.

NOTE: While the Motion Mount is installed, the adjustable electronic ND filter provides a minimum light loss of

1.60 stops (0.48 optical density).

IR FILTER AND LINEAR POLARIZATION

The Motion Mount incorporates an IR-cut filter and new color science, providing accurate and natural color over

a wide range of color temperatures. The IR-cut filter ensures rich, deep shadows in your shots and minimizes

IR contamination at high ND levels, without the need for a separate hot mirror.

The built-in linear polarizer improves image quality by increasing contrast and reducing unwanted glare from

light that passes through the Motion Mount to the image sensor.

SOFT SHUTTER

The Motion Mount soft shutter performs temporal anti-aliasing in your footage, eliminating sampling rate

issues caused by temporal aliasing. This is commonly referred to as the “wagon-wheel effect.” Effectively, the

Motion Mount improves your images and footage by ensuring smooth and natural motion. As its name implies,

the soft shutter “softens” the edges of blur, resulting in crisp, smooth motion and pans.

For more information about temporal anti-aliasing, check out the Temporal Aliasing with Cinema article available

at www.red.com/learn/red-101/cinema-temporal-aliasing.

SQUARE SHUTTER

The Motion Mount square shutter, also referred to as “global shutter,” eliminates rolling shutter artifacts,

such as partial illumination caused by strobes and flashing light. The global shutter ensures uniform exposure

throughout your image, regardless of strobes or motion.

For more information about global shutters, check out the Global & Rolling Shutters article available at www.
