Reference Manual ATOM one SSM500
1.2 Trigger Mode
In this mode the ATOM one SSM500 works as a stand alone camera with internal
recording.
It can record up to 500 frames per second with a memory depth of 30.000 frames. This will
give you a recording time of 1 minute at 500 FPS. By lowering the frame rate the recording
time can be extended accordingly.
It is possible to split the 30.000 frames in up to 4 smaller buffers on demand.
The recording frame rate is independent of the video output format.
The slow motion ratio is defined by:
Slow Motion Ratio = Recording Frame Rate / Output Frame Rate
Examples:
Record 500 FPS / 1080p50 = 10x
Record 500 FPS / 1080p25 = 20x
In addition to that, the playback speed can be slowed down to further increase the ratio.
In trigger mode the camera has 2 independent output channels:
•
Live
◦
Always shows the live stream
◦
The live frame rate is independent of the recording frame rate
◦
Is shown on SDI outputs 1 & 2
•
Playback
◦
Can show the recorded slow motion video.
◦
The slow motion factor is recording FPS / play back FPS
◦
Optional it can show the live image if no playback is running (auto live)
◦
Is shown on SDI outputs 3 & 4
SDI 5 is always showing a live image. This can be used by the camera operator as a
local monitor.
Both output groups have independent image processing pipelines for best flexibility for
color grading and post processing.
Refer to chapter 1.2.2 for workflows details.
Technical details on the Trigger mode can be found in chapter 2.1.

Production Preparation
For any production the camera needs some settings to meet the project requirements.
The following order is recommended:
1. Define lens system / lens control (motors, RCP, etc.)
