Using Timecode

Touching the Timecode display on the home screen, just above the three main controls (Rec, Play, Menu), will take you to the Timecode setup screen (this is also accessible by touching Menu and then Timecode)

Occupying the lower-centre part of the screen is the timecode display with controls to set the start-time of the timecode.

The Timecode modes supported are:

• HDMI (Embedded)
• SDI (Embedded)
• Record Run
• Time of Day
• Auto Restart
• LTC input (via GenLock BNC)

Cycle through these modes by touching the Timecode Source Selector.

SDI / HDMI embedded Timecode

With this setting, the SDI or HDMI input will use the Timecode embedded in the input signal. The controls to adjust the Timecode value are disabled in this menu as you will need to adjust these on the camera.

Note that not all HDMI sources embed Timecode.

Trigger from SDI or HDMI time code

If SDI or HDMI timecode is selected and the camera is in REC RUN mode, the user has the choice to start and stop recording remotely from the source camera SDI timecode.

To enable rolling Timecode Start/Stop functions, simply press the TC icon

shown here. When enabled, pressing the camera Record Stop/Start button will make the Sumo19 start and stop record simultaneously as the timecode starts and stops.

When using the camera in Free Run timecode, the rolling timecode trigger might not work as expected. However, depending on the camera, you can trigger record function by the embedded flag/trigger in the SDI signal. Most higher end cameras have this functionality; if unsure contact us at support@atomos.com

Time of Day

With this setting, each new clip that is created will contain embedded Timecode starting with the time of day when the recording is started. Please check that Sumo19 clock has been set correctly.

This can be set in Menu > Date & Time

If recording is stopped and then restarted while in this mode, there will be a time gap between the last clip and the next one, equal to the length of time the Sumo19 has been out of record.

In Time of Day mode, the controls on the Timecode Setup Screen for adjusting the start-point of the Sumo19 Timecode are not available, as the Timecode is set by the Sumo19’s internal clock.

LTC

If LTC is selected then Timecode will be taken in via the LTC input (refer

page 12). If no LTC signal is present the following icon is displayed and the unit will revert to SDI/HDMI Timecode

Please note that the LTC generator needs to be set to the same frame rate as the input video signal. If the LTC signal is looped through

to the other channel then both recordings will have synchronized Timecode.

Record Run

With this setting you set the starting Timecode for the first clip. The following clips will start at the frame immediately after the out point of the preceding clip. This will continue for all clips that follow. This is also known as continuous Timecode.
