DJP Crew Training - Camera Connections

Introduction

This tutorial provides a comprehensive guide on connecting video cameras to the Blackmagic Design Camera Converters, as demonstrated in Doug Johnson Productions' training video. Understanding these connections is crucial for setting up a professional video shoot, ensuring high-quality signal transmission.

Step 1: Understand Connection Types

Before starting the connections, familiarize yourself with the types of cables and connections used in professional video equipment.

• SDI (Serial Digital Interface)

  • Uses BNC coaxial cables.
  • Robust and provides high-quality signals.
  • Suitable for runs up to several hundred feet.

• HDMI (High-Definition Multimedia Interface)

  • Common in consumer devices and some professional cameras.
  • Easily recognizable and widely available.

• Fiber Optic

  • Transmits SDI signals using glass fibers.
  • Requires careful handling to avoid damage.
  • Can carry signals in both directions with a single cable.

Step 2: Prepare the Camera Converter

The camera converter is central to connecting your cameras to the switcher. Here’s how to set it up:

1. Secure the Camera Converter

   • Use tape to attach the converter to the tripod for easy access.
   • Slide tape under the belt clip and wrap it around the tripod.

2. Connect Fiber Optic Cable

   • Choose a blue or yellow fiber optic cable.
   • Snap it into the optical input jack of the camera converter.
   • Turn on the camera converter and check that the optical signal light is green.

Step 3: Connecting the Camera

Each camera may have different output options. Here's how to connect them:

1. For 4K Cameras (e.g., Sony Z150)

   • Connect an SDI cable from the camera's SDI output to the SDI input on the camera converter.
   • Ensure video is visible on the switcher.

2. For HDMI Cameras (e.g., Sony NX100)

   • Use an HDMI cable from the HDMI output on the camera to the HDMI input on the camera converter.
   • Check that the camera is set to output via HDMI for video to display.

Step 4: Set Up the Monitor

After connecting the camera, it’s important to set up the monitor:

1. Attach the Monitor

   • Use an Israeli arm to position the monitor on the camera.
   • Secure it by tightening the knob.

2. Power the Monitor

   • Connect the monitor power cable to an AC power source.
   • Plug into the DC input on the monitor.

3. Connect Video Signal

   • For HDMI monitors, connect an HDMI cable from the camera converter's HDMI out to the monitor.
   • For SDI monitors, use an SDI cable instead.

Step 5: Establish Intercom Connections

Communication is key during production. Here’s how to set up intercom systems:

1. Connect Headsets

   • Single connection headsets plug into the headset jack.
   • Two connection headsets: plug the red connector (microphone) into the mic jack and the green connector (headphones) into the headphone jack.

2. Use Zoom Controller

   • If available, connect the zoom controller to the camera’s designated port for zoom and focus control.

Conclusion

With these steps, you can effectively connect video cameras to the Blackmagic Design Camera Converters, ensuring high-quality video output and smooth communication during production. Make sure to test all connections and adjust settings as needed. For further learning, consider exploring more advanced features of your camera and converter systems.
