Watch our exclusive film that explains all of the Panasonic LUMIX GH5's filmmaking features


The Panasonic LUMIX GH5 was recently voted the camera that most people were excited about seeing during 2017. Although a new 20.3 megapixel Digital Live MOS sensor (with no low pass filter) helps to offer up to 6K Photo stills extraction at 30fps, it’s the video making capabilities of the camera that we are interested in. To find out more about these just read this article or click in the video window above to watch our in-depth examination of the video specifications of the GH5.

The GH5 delivers Cinema 4K (4096×2160) video at 60p and 4K at 50p and uses the entire width of the sensor when shooting 4K before downsampling the footage in-camera. It has also got 4:2:0 8-bit internal recording, 4:2:2 10-bit internal at up to 30p, plus 4:2:2 10-bit external recording at 50p and 60p, which will give you much more chroma sub-sampling – this means more colour grading capabilities. In fact, this is the colour sub-sampling that’s commonly used for film and broadcast productions to aid more faithful colour reproduction.

Faster readout & processing
With the GH5 the signal readout speed has been accelerated by up to 1.7x in the new Digital LIVE MOS Sensor and a new Venus Engine processes signals at speeds of up to 1.3x faster. This combination helps to realise the camera’s 4K 60p/50p ultra high-definition video recording.

The high-sensitivity MOS Sensor and Venus Engine effectively suppress rolling shutter distortion and realise high-speed readout of full digital signals. This ensures an outstandingly high image quality for every single frame. In addition, the focal length in video recording is kept the same as that in photo shooting with no cropping.

Video format choices
Filmmakers can choose between MOV, MP4, AVCHD Progressive and AVCHD formats at a variety of frame rates, and there is no recording time limit for both Full HD and 4K video. Professional users, who may be working around the world, can set the system frequency to 59.94Hz, 50.00Hz or 24.00Hz.

While ‘Cinelike D’ and ‘Cinelike V’, which have similar gamma setting characteristics for film production, are available in Photo Style for video recording, the GH5 also provides ‘Like 709’ for compatibility with HDTV. A paid software upgrade to support V-Log-L video recording is also available.

Waveform Monitor & Vector Scope
To meet requests from professional users, the GH5 comes with a Waveform Monitor and Vector Scope. It also embeds SMPTE-compliant Time Code either in Rec Run or Free Run count-up methods, helping to make it easy to synchronise multiple video footage or sound sources in the post-production workflow.

5-axis Dual image Stabiliser
The GH5 incorporates what’s known as a 5-axis Dual Image Stabilizer 2 system, which suppresses blurring in more powerful and advanced ways for both photo and video recording, including 4K video. By combining a 2-axis Optical Image Stabilizer and a 5-axis Body Image Stabilizer, it compensates for larger movements that may previously have been uncontrollable. The GH5’s high-precision gyro sensor controls both of the stabilizer systems by studying the focal length and shooting conditions, thus making it possible to use a maximum of five stops slower shutter speeds.

Dual SD memory card slots
The GH5 has a double SD Memory Card slot that’s compatible with high-speed, high capacity UHS-II – a first for any Panasonic LUMIX digital camera. The dual SD card slots allow for concurrent recording as a back-up or continuous from card to card. Users have the flexibility to choose the recording method either in Relay Rec, Backup Rec or Allocation Rec.

Viewfinder & rear LCD panel
The camera has a large Live View Finder with a magnification ratio of approximately 1.52x/0.76x (35mm camera equivalent). A high-precision, high-speed OLED display features 3,680K-dot high resolution and 100% field of view. The rear 3.2-inch free-angle LCD screen is in 3:2 aspect with 1,620K-dot high resolution and has a static touch control system.

HDMI out and wide frame rates
Other key points for video shooting include a Type A, full-sized HDMI output with lock – for live output to external recorders – and variable frame rates from 2fps to 180fps which, at high speeds, will allow for slow-mo shooting at HD levels. An optional plug-in DMW-XLR1 microphone adaptor lets you use an XLR microphone, thus allowing you to record high quality stereo sound.

Firmware updates
In April Panasonic announced the first of its planned 2017 firmware updates (Ver.1.1) for the LUMIX GH5, which expanded the camera’s 4:2:2 10-bit video recording mode. In 4:2:2 10-bit 1920×1080 Full HD [MP4(LPCM)] / [MOV] mode the firmware offers 50p and 25p (PAL), 59.94p, 29.97p and 23.98p (NTSC) and 24p (Cinema) – all at 100Mbps with Long GOP image compression. Whilst in 4:2:2 10-bit Anamorphic mode (3328×2496) it offers 25p (PAL), 29.97p and 23.98p (NTSC) and 24p (Cinema) at 150Mbps with Long GOP image compression.

Firmware Ver.1.1 for the GH5 also includes following bug fixes:
• A problem in which the exposure adjustment did not operate properly during live view standby under specific condition in using (Variable Frame Rate).
• A problem in which afterimages appeared when recording video under high ISO sensitivity settings in using (V-LogL).

Video features to come
Panasonic has said that additional firmware scheduled for release during 2017 will add the following additional video features to the GH5:
• 400Mbps 4:2:2 10-bit All-Intra video recording in 4K 30p, 25p and 24p
• Full HD, high-resolution video recording in Anamorphic mode
• Hybrid Log Gamma in Photo Style mode, which enables 4K HDR video recording, and USB tethering.
