Timecode Input Sources

Timecode BNC

The Timecode Input BNC accepts standard SMPTE timecode signal.

SDI or HDMI Input Embedded Timecode

The PIX 270i can use timecode embedded in the SDI or HDMI (Sony) input signal.
[Timecode/Sync - Timecode Mode] must be set to Ext TC (SDI, HDMI).

Synchronization/Timecode Examples

The following examples illustrate common scenarios where timecode and synchronization can be

employed with the PIX 270i and other devices.

Single Video Camera, no Genlock

SDI/HDMI

In this scenario, the video camera is the master source of the video sync. The timecode can either be

read from the camera or be generated by the PIX 270i. The accuracy of the recording is dependent on

the internal clock accuracy of the camera.

To receive timecode from the camera, set [Timecode/Sync - Timecode Mode] to one of the external

timecode modes for cameras that output standard SMPTE timecode to the PIX 270i’s Timecode BNC.

Alternatively, the PIX 270i can receive timecode from the SDI or HDMI input (if the camera sends

timecode in this way) by setting [Timecode/Sync - Timecode Mode] to Ext TC (SDI, HDMI).

The Setup Menu option [Timecode/Sync - Sync Out] can be set to several valid settings, including

the following:

• Off - sync signal is disabled.
• Genlock, Follows Video In - Genlock for another camera or device is derived from the video sig-

nal of the single camera.

• Wordclock, Follows Video In - Wordclock for an audio device is derived from the video signal of

the single camera.

Single Camera with Genlock Input, Genlocked from PIX

SDI/HDMI

Genlock

In this scenario, the PIX 270i is the master source of video sync. Set the output of the sync generator

to a selected rate and connect the PIX 270i Sync Out (Genlock) to the same camera. Feed the time-

code output of the PIX 270i into the timecode input of the camera.
