RED DIGITAL CINEMA DSMC2 BRAIN with HELIUM 8K S35 Sensor (2018 Unified DSMC2 Lineup) - Manual (Page 125)

FRAME TRIGGER
NOTE: This mode is not available in Stills mode.
NOTE: Audio is not recorded in Frame Trigger mode.
In Frame Trigger mode, the camera records the specified number of frames for each external trigger. This mode limits
the REDCODE based on sustainable record rates.
To use Frame Trigger mode, follow the instructions below:
1. Go to Menu > Settings > Recording > Mode .
2. Select Frame Trigger from the Mode drop-down menu.
3. Use the Limit Recording to fields to set the recording to end at a predefined frame limit (optional).
4. Select a Pre Count and Post Count . For more information, go to "Pre Count and Post Count" on the next page .
5. Close the menu.
6. Start recording.
The overlay displays the number of frames recorded out of the total amount of frames.
NOTE: There may be a delay between receiving the external trigger and capturing the next frame(s). The delay may be
as long one (1) frame period at the current recording frame rate. To completely synchronize frames to an external
trigger, set
Sensor Sync Mode to MoCo . For more information, go to "Sync" on page 149 .
SPEED RAMP MODE
NOTE: This mode is not available in Stills mode.
NOTE: Audio is not recorded in Speed Ramp mode.
Speed Ramp mode lets you program the current recording frame rate to transition to different recording frame rates
during recording.
1. Go to Menu > Settings > Recording > Mode .
2. Select Speed Ramp Mode from the Mode drop-down menu.
3. Use the Limit Recording to fields to set the recording to end at a predefined frame limit (optional).
4. Select a ramp target:
Ramp A/B/C/D : Each ramp target is tied to a specific Target/Duration combination.
Ramp Reset : Ramp to the starting frame rate with the specified Duration.
5. Set the Target frame rate.
6. Set the Duration , which is how long it takes to transition from the current frame rate to the target frame rate.
7. Go to Menu > Settings > Setup > Keys and program a key to one of the following functions:
Record: Start Speed Ramp A/B/C/D
Record: Start Speed Ramp Reset
8. Start recording.
9. To start speed ramp, press the key that you have mapped to start the speed ramp.
The frame rate transitions to the target frame rate during the duration you set up.
NOTE: If using speed ramp mode, select an exposure that is valid for each ramp target frame rate. If the camera
ramps to a frame rate that is incompatible with the current exposure, the exposure changes to the longest
exposure possible for the frame rate.
