- Your Panasonic GH4 camera
- Optionally, an AV.io 4K and a computer with video encoder software

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

|4K UHD (3840×2160)||30 fps, 24 fps||NTSC|
|4K UHD (3840×2160)||25 fps||PAL|
|4K DCI / C4K (4096×2160)||24 fps||CINEMA|

- Press the MENU/SET button on the back of the camera.
- Select the Settings menu (wrench icon) from the on-screen display.
- Select System Frequency.
- Choose the system frequency needed for the frame size and frame rate you want (consult the table above).
