1 Overview
This manual describes the usage of the ATOM one SSM500 (Super Slow Motion) camera
system.
ere is a quick navigation through the document:
•Chapter 1: Overview
Describes the functionality of the SSM500, especially the two different operational
modes, “Trigger” and “SSM”. Please read this chapter as a quick start guide on how
to work with the camera.
•Chapter 2: Technical Details
This chapter describes the internals of the SSM500 in detail and is of special
interest for system integrators.
•Chapter 3: General Usage
Gives information on how to connect the camera and describes the functionality of
the OLED display and the status LEDs.
•Chapter 4: Firmware Update
Describes the different ways that are available to perform a firmware update.
•Chapter 5: ProVideo GUI:
Short introduction into the ProVideo GUI which can be used to control the camera.
•Chapter 6 : Terminal Usage
Specifies the terminal interface of the camera and the way the camera processes
commands.
•Chapter 7 and following: Camera API
These chapters describe the commands that can be processed by the camera
grouped by subject areas.
1.1 Operation modes
The ATOM one SSM500 supports two operation modes:
•Tri er Mode: This mode uses the internal storage space to record and playback
slow motion video with up to 500 frames per second. This version can be used
stand alone.
•SSM Mode (Super Slow Motion 4x): This mode does not use the internal storage
but streams with 240 FPS via four D SDI (4x 1080p60) outputs This version is
intended to be used with external storage / video server solutions (like EVS).
The operation mode can be switched with the switch_mode command, which requires a
reboot. Details can be read in chapter 8.10.

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 recordin 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 showin a live ima e. 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.
1.2.1 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.)

8 of 95 Reference Manual ATOM one SSM500
2. Select the video output format, e.g. 1080i50
3. Select the recording frame rate / slow motion ratio, e.g. 300 FPS = 6x
4. Select number of buffers e.g. 3 x 10.000 frames (~33 seconds @ 300 FPS per
buffer)
5. Select the color profile on the live channel e.g. 6500K (playback will follow
automatically)
6. Setup white balance or use auto white balance
7. Start recording on a buffer
1.2.2 Tri er Workflows
Since the SSM500 Trigger does have multiple independent image processing pipelines,
the color workflow is different to other cameras.
This chapter defines recommended workflows for best results.
Trigger mode supports independent color grading for the live and playback channel.
Depending of the need for the production, 2 different workflow can be defined:
•Link Channels (live = playback)
•Pull Settin s (live → playback)
Important: Both work flows have in common, that the selection of the color temperature /
white balance is defined from the live channel.
This means that any recordin does include white balance from live settings at recording
time. Optionally the white balance can be modified/fine-tuned during playback if needed.
1.2.2.1 Link Channels
In the first workflow, both live and playback image processing are always in sync. The
operator must control only the live output, the playback output will follow automatically.
The command “link_settin s 1” links both channels, see chapter 7.9 for details.
Advanta es
•Very easy to use
•Record and play do always have the same look
•Low workload for the operator
Disadvanta es
•It is not possible to “tweak” the playback without changing the live image
•Risk: During playback, changes of live channel will show up directly “on air”
1.2.2.2 Pull Settings
In the second workflow, both live and playback image processing is independent. The
image engineer can control live and playback settings as wanted. In many cases one

9 of 95 Reference Manual ATOM one SSM500
image engineer is controlling the live image, while a 2nd engineer is controlling the
playback image.
On demand the playback operator can “pull” the settings from the current live image by
running a copy_settin s command, see chapter 7.8 for details. This command applies all
settings from the live channel to the playback channel.
Advanta es
•Full control over live and playback look
•Changes only get applied on demand, when the image engineer decides to do so
(lower risk of having wrong settings “on air”)
Disadvanta es
•igher workload for the operator (ideally two image engineers)
•Risk: Operator must make sure that settings get pulled, otherwise playback can
have wrong look
1.3 SSM Mode
In this mode the ATOM one SSM500 does not use its internal storage. The camera is
steamin in super slow motion speed with up to 240 FPS.
The slow motion ratio is changed by adjusting the number of active phases. There are 4
different phase settings possible:
•1 Phase: SDI 1 → 1x
•2 Phases: SDI 1, SDI 2 → 2x
•3 Phases: SDI 1, SDI 2, SDI 3 → 3x
•4 phases: SDI 1, SDI 2, SDI 3, SDI 4 → 4x
SDI 5 is always showin a copy of phase 1. This can be used for the camera
operator as a local monitor.
The frame rate is defined by the video output frame rate and the number of selected
phases.
FPS = Output FPS * umber of Phases
Examples:
Video Mode 1080p50 on 3 Phases:
FPS = 3 * 50 = 150 FPS
Video Mode 1080p60 on 4 Phases:
FPS = 4 * 60 = 240 FPS
From the image processing perspective, this camera is operated like any “normal” camera.
The image processors of all outputs are configured with the same settings, so no special
workflows are required.

2 Technical Details
2.1 Image Processing Pipeline – Trigger Mode
The following graphic gives an overview of the image processing pipeline in the ATOM one
SSM500 in Trigger mode:
The camera has two independent video processing chains. In the following chapters they
are called “live” and “playback”. Each chain features an image processor that can be setup
independent to match your video production needs.
The output video is send to three SDI outputs for the live chain (SDI 1, 2 and 5) and two
for the playback chain (SDI 3 and 4). Usually SDI 1 to 4 will be connected to the
production equipment while the 5th SDI output is used as a monitor output for he camera
operator.
The live and playback chain have independent video processors which can be configured
with different settings. To switch between the configuration of the live and playback chain
the out command is used.
In front of the two chains is a common module for global image processing tasks, this
includes the white balance and the defect pixel correction. Also the sensor settings like
gain and exposure time will be common for both chains.
The live chain directly plays back the video coming from the image sensor, it has a delay
of 1 frame.
The playback chain reads data from the video storage system. The storage system is
persistent, that means as long as you do not change the video format, the recording frame
rate or the amount of recording buffers (see video_mode, fps_mode and count
commands) you will be able to play back the recorded video even after a power cycle.
For more details on the handling of the recording engine please see chapter 17.
The playback chain can be configured to show a live image, if no playback is running (see
stop_mode command). In that case the image coming from the live video image
