In this guide we’ll show how to make an ARRI ALEXA accept external Timceode and Genlock.
Turn on all your Lockit devices, choose one of them to be the Master Clock – then press-and-hold the green button to broadcast timecode and framerate through ACN and you are set.
Make sure that all cameras and Lockit Devices run on the same frame rate:
- On the Lockit, press green and red simultaneously to enter menu, then and navigate to “Project Rate”
- Set up the Camera as follows:
- Press FPS button in the home screen
- Adjust the “Sensor FPS” to your project base
-
- Enter the TC menu by pressing the dedicated TC button
- Select the "Project" menu
- Select your "Project frame rate"
These settings make the camera accept external Timecode:
- Go to the TC menu
- Go to “Options”
- As “Source" select "Ext LTC"
- As “Mode” select “Free Run”
- For "Generator" select "Regen"
For this camera you need an TC-IO Timecode cable.
Connect it to the LEMO timecode connector
Now the camera accepts the external timecode source.
