Varispeed - RED ONE Operation Manual

To Convert Shutter Speed to Angle Equivalent:
Equivalent Degrees = (Shutter Speed x Frame Rate x 360)
E.g. = (1/48 x 24 x 360) = (8640/48) = 180
Shutter
To Convert an Angle to an Equivalent Shutter Speed:
Equivalent Shutter = 1 / (Frame Rate x 360 / Angle)
E.g. = 1/(24 x 360/180) = 1/(8640/180) = 1/48

VARISPEED

The Varispeed menu supports Variable Frame Rate recording at speeds faster or slower than the Project
Frame Rate and Frame Rate Ramping. Varispeed recordings can be initiated by pushing the Record key,
or by GPI trigger.
NOTE: In all Varispeed modes, audio recording is disabled.
NOTE: In Varispeed modes timecode is written to digital media at a rate equal to the instantaneous
capture rate. This ensures that the recorded REDCODE™ RAW data has valid and sequentially in-
crementing timecode for use by non-linear editing devices.
Note: In Varispeed, the frame rate display turns yellow, the audio panel reports VARISPEED.
