Specifically geared for video shooting, the GH5S features a versatile and capable range of video specs, including the ability to internally record DCI 4K at up to 60 fps and 150 Mbps with 4:2:0 8-bit Long GOP; 30 fps and 150 Mbps with 4:2:2 10-bit Long GOP; and 24 fps and 400 Mbps with 4:2:2 10-bit ALL-I. UHD 4K recording is also supported along with Full HD at up to 240 fps for slow-motion playback. A full-size HDMI port is present on the camera for high-quality output at 4:2:2 10-bit in all settings for use with external monitors and recorders.
Optimizing your recording for post-production color adjustment, the GH5S features a pair of gamma settings suited to capturing a wide dynamic range. V-Log L has been pre-installed on this camera and is used to capture a flat, neutral gamma curve well-suited for grading. Additionally, a High Dynamic Range mode, and Hybrid Log Gamma, can be used to record greater detail in both the shadow and highlight regions of a scene. Additional picture styles are available to provide a more gradable image, such as CINELIKE V and CINELIKE D, as well as an in-camera LUT to make monitoring easier. Also, users will have access to overcranking and undercranking Variable Frame Rate settings which provide speeds up to 2.5x slower in 4K (60 fps) and 7.5x slower in Full HD (240 fps). Also, a 4K Anamorphic mode is available, which will let you record in a proper 4:3 ratio for adjustment in post-production.
For greater recording versatility, the recording system frequency can be changed between 59.94 Hz (NTSC), 50.00 Hz (PAL), or 24.00 Hz (Cine) for worldwide use, and there is no recording duration limit for all settings. Three separate video control panels can also be used—shutter duration/ISO, shutter angle/ISO, or shutter duration/dB—to match various worldwide production needs.
The GH5S is designed to be an expandable system, with multiple options available to help improve video recording capabilities. Examples of this are the included BNC conversion cable for syncing time code settings with an external device for multi-camera setups; LINE input support via the 3.5mm mic input for using an external audio device; and the optional XLR Microphone Adapter that provides XLR inputs and physical controls through a hot shoe connection. Users can also use standard microphones and headphones via the 3.5mm input and output jacks.
