Panasonic has released updated firmware for the Lumix GH4, adding new recording and 4K photo modes.

The new recording mode is a 23.98 fps option in MP4, with AAC audio recording, adding to existing 25fps and 30fps options.

The new 4K photo recording mode, though, offers some new creative opportunities.

The new mode works on the basis that photographers can crop still images out of a 4K video recording, giving an eight megapixel still image. But, by creating a dedicated 4K Photo Mode, Panasonic allows photographers to create images with stills photo aspect ratios, including 4:3, 1:1 and 3:2, as well as 16:9. The cropped out images contain standard, stills photo metadata based on the EXIF standard.

To help with taking stills, users can mark frames using the GH4’s Fn1 button.

The GH4 firmware update also introduces loop recording. With Loop Rec the camera will record, and then retain, the five most recent, 2-minute video files up to the point where the user presses record. Once the loop recording buffer is full, the camera overwrites the oldest of the five files.

Panasonic has also updated its Image App for Android and iOS, and added support for teathered control over USB and third-party software.

The new firmware is now available to download via Panasonic’s global support site.
