8. When you are ready to start the speed ramp, press the key that you’ve mapped to start the speed ramp.

The frame rate transitions to your target frame rate during the duration you set up. After you reach your

target frame rate, the camera continues to record at that frame rate until you stop recording.

NOTE:

If the camera ramps to a frame rate that it cannot maintain with the exposure setting, the camera changes

the exposure to the longest exposure possible for the frame rate. To maintain consistent exposure throughout

the recording, select an exposure that is valid at all ramp target frame rates.

EXTERNAL RECORD ONLY

This mode allows for external recording only. That is, the recording is NOT saved to the camera’s SSD, and

external recording is blocked if an SSD is mounted to the camera. An external recorder is required and can be

triggered automatically via HD-SDI (if supported by the recorder).

BEEP SPEAKER

Off

: The camera does not make a sound when recording starts/stops. This is the default.

Record/Stop

: The camera beeps when recording starts/stops.

FRAME PROCESSING

NOTE:

The Frame Processing screen is not accessible on any EPIC DRAGON or SCARLET-X DRAGON.

NOTE:

Frame processing is not supported in Speed Ramp Mode. For more information about ramping, go to

“Speed Ramp Mode” on page 69

Frame processing allows for the combination of multiple captured frames into one recorded frame. The com-

bination occurs before the resultant frame is encoded. You can select the following frame processing settings:

No Frame Processing, Frame Summing, Frame Averaging.
When in Frame Summing mode or Frame Averaging mode, the current integration time is applied to each frame.

This means if the integration time is not the entire frame time (or 360 degrees) there will be gaps between the

images used to create the combined frame. This may lead to unexpected motion artifacts.
The effect of frame processing is only visible during record. In Frame Summing mode, this means the exposure

will change between preview and record. You may have to experiment with your exposure and frame processing

settings before you achieve the effect you want.

NO FRAME PROCESSING

Normal frame processing mode. The Frames to Process selection does not affect your recording.

FRAME SUMMING

Combines the specified number of frames into one frame, and adds together the exposure time for each of the

original frames. The resultant frame has an effective integration time that is equal to the current integration time

multiplied by the number of frames.
For example, if you select 16 as your Frames to Process value, and set your exposure to 1/48 sec, your result-

ing image has an effective integration time of 1/3 sec (16 x 1/48).
Frame summing results in a final image that is brighter and possibly blurrier than any of the original frames, so

you can use frame summing to achieve the effect of long-exposure.

FRAME AVERAGING

Combines the specified number of frames into one frame, and averages the exposure time for each of the origi-

nal frames. The resultant frame has an effective integration time that is equal to the current integration time.
For example, if you select 16 as your Frames to Process value, and set your exposure to 1/48 sec, your result-

ing image still has the exposure value of 1/48 sec, along with the effect of long-exposure.
You can use frame averaging to achieve the effect of long-exposure along with the benefits of reduced noise.

However, frame averaging does affect motion blur characteristics.
