What you need

To configure your Panasonic GH4 for 4K video capture (with AV.io 4K or Pearl-2), you need:

  • Your Panasonic GH4 camera
  • Optionally, an AV.io 4K and a computer with video encoder software
  • Or, optionally, a Pearl-2 for video capture

(Video capture works with or without an SD card in your Panasonic GH4.)

Step 1: Choose 4K UHD (3840×2160) or 4K DCI (4096×2160)

The Panasonic GH4 camera supports two different 4K frame sizes and a number of frame rates. The choices available depend on your camera’s system frequency setting. Check the table below to see which system frequency is needed for your chosen frame size and frame rate.

Frame size Frame rate(s) System frequency
4K UHD (3840×2160) 30 fps, 24 fps NTSC
4K UHD (3840×2160) 25 fps PAL
4K DCI / C4K (4096×2160) 24 fps CINEMA

The first step in configuring your camera for one of these video options is to set the appropriate system frequency.

  1. Turn the camera on.
  2. Press the MENU/SET button on the back of the camera.
  3. Select the Settings menu (wrench icon) from the on-screen display.
  4. Select System Frequency.
  5. Choose the system frequency needed for the frame size and frame rate you want (consult the table above).4K output
  6. If requested by the camera, turn the camera off and on again to apply your change.(
