Even a moment’s waste matters in professional shooting condition, hence it is possible to make target setting intuitively thanks to the optimum layout of control devices on DMC-GH4 . The DMC-GH4 also incorporates Wi-Fi® with NFC technology, terminals highly connectable to external equipment. Now RAW files can be developed in camera.
Evolving further in every aspect – performance, mobility, durability and expandability, Panasonic is proud to offer DMC-GH4 for a reliable first camera to professional field photographers, film creators and hybrid photographers.
1. The Newly Developed 16.05-Megapixel Digital Live MOS Sensor and Venus Engine Achieving High Speed, High Sensitivity Image Recording
Panasonic developed new 16.05-megapixel Digital Live MOS Sensor for DMC-GH4 that achieves high quality, high sensitivity image recording with quick response. Approx. 50% higher speed signal readout suppresses rolling shutter effect even when using electronic shutter or recording motion image. The maximum number of recordable images is up to 40(including RAW) / 100 (excluding RAW). Taking full advantage of the Live MOS Sensor, gradation range is expanded by max.1/3 step at low ISO end with fine tuning control by the Venus Engine. Plus, superior noise reduction realizes max.60 min long exposure in B(bulb) mode.
The image processor Venus Engine is also newly developed dramatically boosting its performance with new quad-core CPU that lets high speed signal processing required for rich video recording such as 4K. The advanced Multi-process NR (Noise Reduction) applies effective noise reduction and edge processing according to each component frequency. Plus, newly added Random Filter granulates chromatic noise to be blended into the image even more naturally. As a result, the max. ISO 25600 is achieved. On the other hand, optimizing the combination design of new sensor, new imaging engine and low-pass filter enhances the limit resolution by more than 5% while suppressing moire. Newly adopted aperture filter is capable of controlling over wider frequency range. It adjusts the amount of sharpness according to the frequency level, resulting in faithful stereoscopic effect. The Venus Engine also improves color reproduction with accurate evaluation of each color even it is similar not only in color phase but also in saturation and luminosity.
The combination of the Digital Live MOS Sensor and the Venus Engine achieves stunning picture quality in its natural way – that is what LUMIX aspires for.
2. The World’s First Digital Single Lens Mirrorless (DSLM) Camera Recording High Quality Video in 4K – To Meet Professional Quality and Standard
The predecessor DMC-GH3 created an industrial sensation with its outstanding video recording performance that meets the professionals’ quality and standard. The new DMC-GH4 further evolves to bridge the gap of consumer video camera and professional video camera. One of the most prominent advance is unlimited*1 4K video recording (Cinema 4K: 4096×2160 / 24 fps and QFHD 4K: 3840×2160 / up to 30 fps) in MOV/MP4*2. The DMC-GH4 is also capable of Full- HD video with ultra high bitrate at 200 Mbps (ALL-Intra) or 100 Mbps (IPB), which does not have limit of recording time*1. Users can freely choose the format from MOV, MP4, AVCHD Progressive and AVCHD at a variety of frame rates according to the usage [Figure#1]. In MP4 / MOV, high quality sound in LPCM (Linear Pulse Code Modulation) is recordable. For the global business of professional users, the system frequency can be flexibly selectable between 59.94Hz (23.98Hz) / 50.00Hz / 24.00Hz.
The DMC-GH4 is also capable of real-time image output to the external monitor in 4:2:2 / 8-bit*3 via an optional micro HDMI cable simultaneously while recording video. Even 4:2:2 / 10-bit is available which is suitable for the professional video making that requires serious monitoring of the footage. Users can choose to output only the recording content or the content with the setting menus individually depending on a display.
Plus, the VFR (Variable Frame Rate) enables recording video with slow/fast motion such as 96 fps, 4x, all in Full-HD[Figure#2]*4. Time Lapse/ Stop Motion Animation video can be produced in camera, too.
For more precise control over video image quality, the DMC-GH4 integrates Zebra Pattern to watch white wash-out or Focus Peaking. The DMC-GH4 even allows Master Pedestal system is newly integrated with which users can adjust the brightness balance ±15 steps based on the color of black. Gamma presets exclusively for video recording are newly available in Creative Video mode – “CINELIKE D” and “CINELIKE V” for rich video expression like a cinema. Synchro Scan mode is also newly availableto reduce suppress flicker. It is selectable to display Center Marker while recording.
The DMC-GH4 is equipped with functions that meets global standard for synchronous video recording. 1KHz Test Tone and Color Bars(SMPTE / EBU / ARIB Standard) are newly available on DMC-GH4. The DMC-GH4 also embeds SMPTE-compliant Time Code either in Rec Run or Free Run count-up methods, which makes it easy to synchronize the multiple video footage or sound source in the post production workflow. Time Code Value can be started at any point of [Reset], [Manual Input] and [Current Time]. Drop frame or Non Drop Frame time code is selectable*5. When recording the video in MOV, AVCHD Progressive, AVCHD or MP4(LPCM), the DMC-GH4 automatically generates multiple seamless files for continuous recording. During playback, the AVCHD Progressive / AVCHD files are reproduced with seamless, interruption-free continuity.
A total of 22 LUMIX G digital interchangeable lenses offers any creative perspective according to the scene. Especially those crowned as HD lenses allows silent, high performance AF control suitable for video recording.
* 1 — Motion image can be recorded up to 29 min 59 sec depending on the recording format and the camera’s sales area.
*2 — Use SDXC/SDHC Memory Card compatible with UHS Speed Class 3 (U3) when using high bitrate video recording mode over 100 Mbps.
*3 — Setting the HDMI output picture quality [4:2:2 10bit]:You can output the image through the HDMI connection in higher picture quality, but you cannot record it as a motion picture or still pictures. Ideal when the HDMI output is to be saved on external devices. [4:2:2 8bit]:You can record the image while outputting it through the HDMI connection. Ideal for recording while checking the motion picture on an external monitor. When using 4:2:2 / 8-bit output, video is recorded in 4:2:0 / 8-bit on SDXC/SDHC Memory Card.
*4 — In 24p playback. Effect value varies depending on the recording format and frequency.
*5 — When system frequency [59.94Hz] is selected
