HLG

GH5 Firmware Update 2.0

By cameraman

This week Panasonic announced an update to the increasingly popular GH5. While some of the other camera manufacturers appear to be holding back on providing innovative video functions in the DSLR form factor, Panasonic are clearly going for it… and it shows.

Big news for video shooters is the addition of an ALL-Intra recording mode. This gives us 4:2:2 10-bit ALL-Intra recording at 200Mbps in HD resolutions and 400 Mbps at UHD or 4K. You’ll need to use the new speed Class 90 SD cards to push it to the limits, but this seems a small price to pay for such potential quality.

There’s now a 4K HDR gamma curve compatible with BT.2100 which Panasonic are calling HLG (Hybrid Log Gamma). You can choose HLG in the Photo Style menu when you want to enter the world of high dynamic range. There’s also a low bit-rate 4K HEVC recording mode for playback on HEVC compatible monitors.

Also recorded in HEVC is the high resolution anamorphic mode which enables video recording using an effective pixel equivalent to 6K (18 megapixels) with a suitable 4:3 anamorphic lens. So for PAL areas we’ll have the option of 4992 x 3744 at 4:2:2 10-bit and 200 Mbps Long GOP.

When the GH5 was first launched, many people complained about the auto focus performance when shooting video. The good news is that it looks like Panasonic have listened and report improvements to auto focus tracking and performance in low contrast situations. We’re looking forward to testing this soon.

With a new handshake correction mode in the body I.S. (image stabiliser), many improvements to still photo modes and the usual bug fixes, this looks like being an important upgrade for GH5 owners. Panasonic say it’ll be available late September:

Until recently, I’ve been more than happy → continue…

Video Highlights

ALL-Intra Video Recording

4:2:2, 10-bit ALL-Intra has been added to the 4K/FHD video recording mode. Available in 4K and C4K 24p/25p at a healthy 400Mbps, this should satisfy the needs of most color and post work. An ALL-Intra bit rate of 200Mbps is available in FHD.

HDR

The GH5 records video with a designated gamma curve compatible with ITU-R BT.2100, and you can now choose Hybrid Log Gamma (HLG).

6K Anamorphic Mode

“High Resolution Anamorphic Mode” records video with a 4:3 aspect ratio suitable for 1.33x and 2x anamorphic lenses. The “6K” pixel size for this mode is 4992×3744. Before you get too excited, this mode records Long GOP HEVC at 200Mbps only. However, ALL-Intra at 400Mbps is available in 4K Anamorphic (3328×2496).

Anamorphic Desqueeze lets you view a corrected image in Cinescope size while recording with 2.0x and 1.33x Anamorphic lenses.

Video guide lines offer a variety of aspects, such as 2.39:1, 2.35:1, 16:9, and 1:1 while recording video. These can be used in all video recording modes.

I.S. Lock

I.S. Lock (video) compensates for handshake when the viewing angle is fixed. A new handshake correction mode provides optimum correction → continue…
