RED MOTION MOUNT OPERATION GUIDE
955-0013, REV-K | 6
The RED MOTION MOUNT®is a revolutionary and adjustable lens mount system for your camera. The
MOTION MOUNT integrates a global shutter, temporal anti-aliasing soft shutter, and variable neutral density
(ND) system. This enables 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.
NOTE: The MOTION MOUNT is compatible with EPIC, SCARLET®, and WEAPON®cameras.
VARIABLE ND FILTER
The electronic variable ND filter provides adjustable optical density for the camera. The amount of optical
density varies based on the active shutter type. Adjust the ND value using a touchscreen or user keys, without
having to change physical filters.
Soft/Square Shutter: Range is 0.48 to 1.20 (1.60 to 4.00 stops)
ND Only: Range is 0.48 to 2.40 (1.60 to 8.00 stops)
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, see 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, see the Global & Rolling Shutters article available at www.red.com/
learn/red-101/global-rolling-shutter.

OUT-OF-FOCUS FIELD MODIFICATION
Use of “ND Only” with a high ND value and wide aperture may cause unwanted results, including distortion or
flaring in the out-of-focus field. In some instances, vignetting may also occur at the edge of the image. This is
typical when using lenses with smaller image circles. RED recommends that you do not exceed 4.00 stops of
ND when shooting with wide apertures.
NOTE: For instance, if the MOTION MOUNT is set to 8.00 stops of ND, and the lens is set to T1.8, instead of
the normal circular bokeh pattern, the out-of-focus area may have unwanted or intense flare.
AVOID FLARE AND DISTORTION
Use the following tips to avoid or dramatically reduce flare and distortion.
Increase T-Stop to T4.0 or greater: Increase the T-Stop to T4.0 or greater to dramatically reduce bokeh
distortion.
Reduce ND setting: Reduce the ND setting to five (5) stops or less to produce a more symmetrical bokeh.
Install a traditional ND filter: Use a traditional ND filter if a shot requires a wide aperture (to limit depth-of-
field) and also requires eight (8) stops of ND. Adjust the MOTION MOUNT to four (4) stops of ND and install
an ND filter. This removes bokeh distortion and flare, and also enables the use of the Soft and Square
shutter types.
NOTE: Effects of flare and distortion are negligible at apertures greater than T4.0. Flare and distortion may vary
based on the lens. RED recommends testing each lens in conjunction with the MOTION MOUNT before an
important shoot.
NOTE: Selecting an ND value over 4.00 stops in “ND Only” results in the ND value on the main screen overlay
turning yellow. The following message displays on the MOTION MOUNT menu: “High ND with wide apertures
may cause bokeh asymmetry”.

DISPLAY EFFECTIVE ISO
When using any ND filter, including the MOTION MOUNT, the effective ISO is reduced because the ND filter
reduces light transmission to the sensor. To display the effective ISO (on the main screen) and native camera
sensor ISO (in the ISO/FLUT®screen), follow the instructions below:
1. Go to Menu > Settings > Display > Modes > Lens.
2. Select the MOTION MOUNT ISO Pull setting that you want:
‒On: Displays the effective ISO.
‒Off: Displays actual ISO.
3. Select Close to return to the main screen.
The effective ISO displays in yellow.

4. Go to Menu > Settings > Look > ISO/FLUT, or select ISO in the Upper Status Row (Basic Menu).
5. Select an ISO value on the slider.
NOTE: Remember, changing the effective ISO changes the native ISO of the camera and NOT the ND value.
To view or change the native ISO, press and hold the ISO value to access the Advanced ISO menu. The
native ISO is the first value.
NOTE: RED®recommends that you follow standard exposure best practices and select your ISO value based
on the native ISO.

DISPLAY NEUTRAL DENSITY (ND) SETTINGS
You can configure how the ND settings display in the graphical user interface (GUI).
1. Go to Menu > Settings > Display > Modes > Lens.
2. Select one of the following MOTION MOUNT ND display settings:
‒Fraction: Displays the neutral density value as a fraction of light transmission.
‒Density: Displays the neutral density value as an optical density value.
‒Stop: Displays the neutral density value as a stop loss.
3. Select Close to exit.
The ND value displays in the top left corner of the Live Action Area on the GUI.
NOTE: Using a high ND with wide apertures may cause asymmetrical bokeh. If you select an ND value over
4.00 stops with “ND Only” selected, the ND value on the main screen overlay turns yellow. A warning
message also displays in the MOTION MOUNT menu on the camera. For more information about bokeh
asymmetry, go to “Out-of-Focus Field Modification” on page 15.

3. Select a Shutter Angle or Int. Time (Integration Time).
SOFT SHUTTER
The MOTION MOUNT Soft shutter is a breakthrough for cinematography, using a liquid crystal shutter to solve
CMOS rolling and global shutter problems. Different from a standard global shutter, the Soft shutter causes the
liquid crystal to rapidly ramp from opaque to clear in a rounded wave. This exposes the sensor to light, taking
many discrete captures of the scene. This technique eliminates the effects of temporal aliasing and reduces
rolling shutter artifacts.
Temporal Aliasing Advantages:
Shows correct direction of rotation of cyclical motion, such as rotating propellers.
Softens blur while preserving clarity.
Reduces judder while panning.
Renders movement accurately and naturally.
Reduces flickering without requiring continuous or synchronized lighting.
Rolling Shutter Advantages:
Reduces striping or tearing artifacts from uncontrolled strobes and flashes.
Reduces skew, also known as the “jello” effect, so that fast-moving subjects are not angled or sheared.
Ensures that images are not blurred or wobbled due to rapid camera movements.
SOFT SHUTTER FRAME RATES
You can use the MOTION MOUNT shutter at frame rates up to 109.98 FPS, but the Soft shutter is most effective
at reducing temporal aliasing artifacts and rolling shutter artifacts at lower frame rates.
SOFT SHUTTER ANGLE
The Soft shutter angle ranges from 62.1° to 194.4°. The available shutter angle range at any given time
depends on the selected frame rate.
For the most natural and realistic motion, use a Soft shutter angle of 194.4°. Then, adjust the shutter angle if
necessary.
