INTRODUCTION
The DSMC®RED MOTION MOUNTTM is a revolutionary and fully-integrated system that combines a variable
neutral density (ND) filter, IR cut filter, linear polarizer, global shutter, and temporal anti-aliasing soft shutter into
a single lens mount for your EPIC or SCARLET Digital Still and Motion Camera (DSMC).
VARIABLE ND FILTER
The electronic variable ND filter provides an optical density range of 0.48–1.20 (1.60–4.00 stops) when the
MOTION MOUNT shutter is enabled, and an optical density range of 0.48–2.40 (1.60–8.00 stops) when in ND
Only mode. You can quickly adjust the ND value through the DSMC interface or the user keys, eliminating the
need to manually swap out ND filters.
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 in particular ensures rich, deep shadows. The IR-cut
filter minimizes IR contamination in your shots, even at very high ND levels, which ensures that the camera does
not require a separate hot mirror.
Due to the built-in linear polarizer, light that passes through the MOTION MOUNT becomes vertically polarized.
MOTION MOUNT SHUTTERS
The MOTION MOUNT soft shutter performs temporal-anti-aliasing in your image, eliminating the wagon-wheel
effect so that you capture realistic and natural motion. As its name implies, the soft shutter softens the edges
of blur, resulting in sharper yet smoother 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.
The MOTION MOUNT global shutter (referred to in the user interface and the rest of this document as the
“square shutter”) eliminates rolling shutter artifacts, such as partial illumination caused by strobes. 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.red.com/learn/red-101/
global-rolling-shutter.

NEUTRAL DENSITY (ND) SETTINGS
The MOTION MOUNT has a variable ND filter that incorporates an IR cut filter and a polarizer. You can easily
adjust the ND setting in increments down to 0.01 stops directly through the DSMC on-screen display, or by
programming the increment and decrement functions to the DSMC keys. For more information on programming
keys, go to “Map Keys to Adjust MOTION MOUNT Settings” on page 22.
The variable ND functionality is always enabled when using the MOTION MOUNT.
The maximum shutter angle is restricted when you’re in ND Only mode and the ND is below 0.60 (2 stops). If
you are using a particular frame rate in ND Only mode and can’t select your desired shutter angle, increase your
ND value to 0.60 (2 stops) or above.
NOTE: ND level cannot currently be changed during recording.
SELECT ND SETTINGS
1. Navigate to Settings > Setup > Lens > Motion Mount.
2. Select an ND value using the ND Value slider, or enter a value for any of the following fields:
‒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 an ND Increment Size, if needed. If you select Custom, enter the new increment size in the field next
to the ND Increment Size drop-down menu. You can select any increment in the range 0.01–4.00 stops.
NOTE: If you select an ND value over 4.00 stops while in ND Only mode, the ND value on the main screen
overlay turns yellow, and the following message displays on the Motion Mount screen: “High ND with wide

OUT-OF-FOCUS FIELD MODIFICATION
In ND Only mode, if the MOTION MOUNT is set near the end of its ND range and used with a very wide aperture
you may notice a modified out-of-focus field (bokeh), and possibly some vignetting at the edge of the image
with smaller image circle lenses. We recommend that you do not shoot past 4 stops of ND on the mount if you
are shooting wide open.
For instance, if the MOTION MOUNT is set to 8 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 flaring mostly in one direction.
There are several ways this flaring can be avoided. If the lens aperture is changed to a T-stop of 4.0 or greater,
the bokeh distortion will be dramatically reduced. Also, the ND value of the MOTION MOUNT can be reduced
to produce a more symmetric bokeh. This effect begins around a density value of 5 stops (ND 1.5, or 1/32),
and becomes more apparent as the value approaches 8 stops.
If a shot requires a wide-aperture to limit depth-of-field, and 8 full stops of ND are needed due to the scene
illumination and shutter settings, it is recommended that a 4 stop (ND 1.2, or 1/16) normal ND filter be used in
addition to the MOTION MOUNT. This would also allow use of the global MOTION MOUNT shuttering modes
during the shot as well as variable ND, and the bokeh will have no distortion.
The flaring effect may vary based on the particular lens used or setup, so RED recommends testing your setup
before shooting. Again, this effect will be negligible at apertures with T-stops of 4.0 or greater, and it does not
appear in the soft and square shutter modes.
If you select an ND value over 4.00 stops while in ND Only mode, the ND value on the main screen overlay
turns yellow, and the following message displays on the Motion Mount screen: “High ND with wide apertures
may cause bokeh asymmetry”.

SOFT SHUTTER
The MOTION MOUNT soft shutter is completely new to the fields of photography and cinematography. All shut-
ters prior to the MOTION MOUNT either use a rolling shutter or start and stop recording abruptly. When the soft
shutter mode is enabled, the MOTION MOUNT’s liquid crystal ramps from opaque to clear in a rounded wave.
This shuttering technique completely eliminates temporal aliasing artifacts and reduces rolling shutter artifacts.
Here’s an overview of how the soft shutter eliminates temporal aliasing artifacts:
Shows correct direction of rotation of cyclical motion, such as rotating propellers.
Softens blur while preserving clarity.
Reduces judder while panning.
Renders human movement accurately and naturally.
Reduces flickering without requiring continuous or synchronized lighting.
Here’s an overview of how the soft shutter reduces rolling shutter artifacts:
Reduces striping or tearing artifacts from uncontrolled strobes and flashes.
Reduces 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 120 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 22.5° 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 shutter angle of 194.4° when in soft shutter mode. Then, adjust
the shutter angle if needed.

The MOTION MOUNT square shutter is a global shutter that provides consistent, full illumination for every
frame. Skewed and smeared artifacts no longer affect your image as the MOTION MOUNT fundamentally
changes the way your camera exposes for motion.
Here’s an overview of how the square shutter eliminates rolling shutter artifacts:
Reduces striping or tearing artifacts from uncontrolled strobes and flashes.
Reduces 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.
SQUARE SHUTTER FRAME RATES
You can use the MOTION MOUNT shutter at frame rates up to 120 fps, but the square shutter is most effective
at reducing rolling shutter artifacts at lower frame rates.
SQUARE SHUTTER ANGLE
The square shutter angle ranges from 22.5° to 180°. The available shutter angle range at any given time de-
pends on the selected frame rate.
For the most natural and realistic motion, use a shutter angle of 180° when in square shutter mode. Then, ad-
just the shutter angle if needed.

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. The MOTION MOUNT and DSMC give you the ability to see both the
effective ISO (on the main screen) and the native camera sensor ISO (in the FLUT®screen).
While the effective ISO is displayed on the main screen, you should continue to follow standard exposure best
practices and select your ISO based on the camera’s native ISO.
ENABLE EFFECTIVE ISO SETTING
1. Navigate to Settings > Display > Modes.
2. For the Motion Mount ISO Pull setting, select one of the following:
‒On: Display the effective ISO.
‒Off: Display actual ISO.
3. After you enable the setting, navigate back to the main screen.
The effective ISO is displayed in yellow.

4. To change the effective ISO, tap the ISO value and select a different ISO on the slider. However, changing
the effective ISO changes the camera’s native ISO, and NOT the ND value.
To view or change the camera’s native ISO, press and hold the ISO value, and the Advanced ISO menu dis-
plays. The native ISO is the first value.
