Magic Motion; Audio Recording; Microphone Level Analog Inputs - Red Epic Epic-M Operation Manual

NOTE: If you ignore the X-track completely, you will have a standard exposure with 13.5 stops of
native dynamic range just as if you had not enabled HDRx. For this reason, we encourage the A-
track exposure to be "normal" as it provides the most options. If you are tempted to shoot "over-
under", you are then fully committed to using HDRx and your postproduction options are reduced.
NOTE: When recording in HDRx mode the camera records twice as many frames, so the maximum
frame rate, minimum REDCODE ratio, and maximum record time on your media will be cut in half.

MAGIC MOTION™

Shooting at 24fps and with an 180 degree (1/48th) shutter on a film or digital camera may create an
optical illusion we are familiar with, however it is not really the way the eye sees motion. To understand
this, ask someone to stand in front of you and swing their arm over their head from one side to the other.
What you would observe in the recording is a constant motion blur until the arm stopped. What your eye
sees though is both motion blur AND a sharper reference to the arm and hand all along the motion path.
"Magic Motion" provides such a combination of motion blur (A-track) and a sharper reference (X-track),
with the bonus of extreme dynamic range not available with any other motion capture camera system.

AUDIO RECORDING

The RED EPIC can record up to two discreet channels of microphone level uncompressed 24-bit, 48 KHz
audio (four channels of microphone level or line level audio inputs when equipped with a PRO I/O
Module), that are synchronized with video and timecode, to REDMAG 1.8" SSD media.
Input signals are routed via a high quality pre-amplifier and soft clip limiter in order to achieve the desired
audio reference / recording level and to maximize dynamic range.
To assist with audio reference level setup, the camera provides a color-coded 4dB per division Peak Level
meter in the Graphical User Interface with 0dBu (-20dBFS) and +4dBu (-16dBFS) Witness Marks. Meter
range is –36dBu to +20dBu (-56dBFS to 0dBFS) with audio input type and audio input clipping indication.
Audio monitor output options include a 2-channel headphone output on the camera Brain and 2-channel
line level analog outputs from the optional PRO I/O Module, plus 2-channel and 4-channel 24-bit 48KHz
uncompressed digital audio embedded in the HD-SDI output.

MICROPHONE LEVEL ANALOG INPUTS

The recording level of Microphone inputs are affected by the sensitivity of the microphone and the Gain
setting of the camera's pre-amplifier. Available pre-amplifier range is +8dB to +62dB, with a default value
of +32dB. The camera operator should choose a Gain value that aligns the input signal to the 0dBu
reference line drawn through the camera's peak meter (or +4dBu line if referencing to that level).
This setting provides up to 30dB of input signal headroom above reference 0dBu level before clipping
(26dB for +4dBu reference level) and maximizes the signal to noise ratio of the 24-bit digital recording.
