In this guide we’ll show how to make an ARRI ALEXA Mini 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 frame rate 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:
- Pres the TC button
- Go to “Project Rate”
- Adjust “Project Rate”
These settings make the camera accept external timecode:
- Go back to the Timecode menu
- Go to “Options”
- As “Run Mode” select “Free Run”
- As “Mode” select “Regen”
For this camera you need an TC-IO-RA timecode cable.
Connect it to the LEMO timecode connector
Now the camera accepts the external timecode source.
Genlock
If your setup requires Genlock, you can use the same setup. ARRI cameras can lock their sensor to an accurate timecode input via Lockits.
- Enter Menu
- Go to “System”
- Go to “Sensor”
- As “Genlock Sync” select “TC IN”
The camera is now Genlock synced to the ACN timecode.
