The DMC-GH4R features 4K video recording in MOV/MP4 and high-bitrate Full-HD video recording up to 200Mbps without recording duration limit. V-Log L recording offers exceptional flexibility as well as wider dynamic range for colour grading in post-production process. For the global business, the system frequency can be selected from 59.94Hz(23.98Hz)/50.00Hz/24.00Hz. A real-time image output to the external monitor via an optional microHDMI cable is also available. The VFR enables recording video with slow/fast motion in full-HD.
The Venus Engine dramatically boosts its performance with quad-core CPU that enables high-speed signal processing required for rich video recording such as 4K. Integrating superior noise reduction systems, the DMC-GH4R enables shooting at max. ISO25600. The combination of the 16.05-megapixel Digital Live MOS Sensor and the Venus Engine dramatically improves sensitivity, gradation performance, resolution and colour reproduction to achieve even higher picture quality. Yet its image description is natural - that is what LUMIX aspires for.
With the 4K Photo feature, you can capture perfect moments at 30 fps in 8-megapixel equivalent resolution. 12 fps / 7 fps with AFC burst shooting with full-resolution is also available. The high-precision Contrast AF integrates DFD (Depth From Defocus) technology to achieve ultra-high speed AF of approx. 0.07 sec (In AFS, with H-FS14140 or H-HS12035). Both the 2359K-dot LVF (Live View Finder) and the 1036K-dot rear monitor adopt OLED to achieve high-speed response with minimum time lag while enhancing the resolution.
To be tough enough to withstand even heavy field use, the main structure of the DMC-GH4R is composed of magnesium alloy full diecast front/rear frame. It also features splash/dustproof construction thanks to the sealing on every joint, dial, and button. The shutter unit is also redesigned to be even more durable for approx. 200,000 times release (Panasonic in-house examination). It offers highest shutter speed at max. 1/8000. Both built-in/external flash can be synchronized with max.1/250 second shutter speed.
External components are designed to be operated easily without taking eyes off from the viewfinder. The 3 dials and the main dial now come with lock structure. A dedicated button allows direct reach to exposure compensation, white balance adjustment or ISO setting. The DMC-GH4R comes with a variety of connection terminals such as 3.5mm mic. jack and 3.5mm headphone jack. With the Wi-Fi® connectivity with NFC technology, you can connect the camera to your smartphone/tablet anywhere at one-touch. In-camera RAW development is also available.
