Loving the live #HLG coverage of the Spain/Albania game from the Euros (and I’m not even a football fan!)
BBC are the only terrestrial broadcaster who are driving #HDR and #UHD adoption.

FastFlix is a free GUI for HEVC and AV1 encoding, GIF/WebP/AVIF creation, and more! It needs FFmpeg (version 4.3 or greater required, 5.0+ recommended) under the hood for the heavy lifting, and can work with a variety of encoders.

BBC R&D is one of the four key developers who have been awarded an Emmy Award for the high dynamic range standard.

BT.2100 has "enabled HDR to become widely practiced and enjoyed by consumers."

#HDR grade on the new Attenborough series is excellent.
Although the iPlayer has less HDR content than Netflix it is less variable; all #HLG content (live & post-produced) is compelling unlike much #DolbyVision content which looks like very bright SDR.

Brazil v. Serbia game in HDR on the iPlayer looks great. Those Brazilian strips are very yellow! #HLG

Vimeo Now Supports Upload and Playback of Dolby Vision Content

Vimeo has announced that it is the first to bring the ability to host, share, and playback videos shot in Dolby Vision and uploaded through Apple devices.

The launch comes as Dolby and Vimeo have partnered to allow Apple device users to upload and share content that has been recorded in Dolby Vision onto Vimeo without having to worry about how the HDR format translates and instead can know that anything uploaded to Vimeo will look the same as it does on their devices.

Originally launched in 2014, Dolby Vision is mainly seen as an HDR format that is heavily used in both commercial cinema and home theater applications. It is regarded as the highest quality video experience available today as it offers rich and vivid picture quality filled with incredible brightness, contrast, color, and detail. However, until now, playback was limited to major media platforms (like Netflix).

Dolby Vision support has become nearly standard on all mid to high-level television sets from various manufacturers. While most can consider Dolby Vision to be an HDR standard, it is actually a set of technologies that cover content creation, distribution, and playback. Dolby Vision content contains dynamic metadata that is used to adjust the brightness, color, and sharpness of each frame in a video to match the display color volume.

But while Dolby was the first to bring an HDR format, the subsequent years would find the landscape muddied and convoluted by various other standards. At the time of publication, there are five major competing formats, support for which is broken up across different streaming platforms and television manufacturers: HDR10, HDR10+, Hybrid Log-Gamma (HLG), Dolby Vision, and Advanced HDR by Technicolor. All five versions require specific support from streaming services and screens in order to work properly.

While HDR10 is considered a "standard" and supported widely, any content that is shot, edited, and delivered in Dolby Vision won't look quite the same if it has to be translated to HDR10. Uploading videos that have been shot in Dolby Vision to a platform like YouTube, for example, can result in badly rendered color and exposure.

When Apple announced that it would be supporting Dolby Vision capture on the iPhone 12 last year, the Silicon Valley giant's influence seemed as though it could clean up the messy HDR landscape.

With Vimeo's announcement combined with the number of new televisions that are signed on to support the format, that might actually be happening. What may have been frustrating to Apple iPhone 12 video shooters in the past year is that even though they were able to shoot in Dolby Vision, playing back that content was not as easy: users have not been able to upload and share those videos online in their full quality.

Vimeo now makes it possible for anyone who shoots Dolby Vision content on their iPhone to share and playback that content across the web so videos can be viewed in the exact picture quality intended by the creator. Uploading this video content is integrated directly into the iOS photos app once a user installs the Vimeo app, and anyone can sign up for a basic Vimeo account for free.

Dolby Vision support is integrated into Vimeo starting today.

Panasonic To Add 5.9K 12-bit RAW Video to S5 and Two-Year-Old S1

Panasonic has announced a firmware update program for its line of Lumix S full-frame cameras that includes the S1, S1R, and S5. Even though the S1 was announced over two years ago, the company will update it to capture 5.9K video at up to 30 frames per second in 12-bit RAW.

The age of a camera doesn't seem to affect how Panasonic views if it should provide major support to it, as these updates add significant performance enhancements that could very easily be argued should be reserved for a next-generation camera body. While some of these updates are only available to those who paid for additional video enhancements at launch, this level of support so long after release is still worthy of praise.

The S1, S1R, and S5 will all receive major enhancements when the firmware becomes available on July 12.

For those who purchased the Upgrade Software Key DMW-SFU2 -- an optional $200 video-focused upgrade that is currently included with new purchases of the camera -- the Panasonic S1 will gain RAW video output over HDMI to a Blackmagic Video Assist 12G HDR and will be recorded as Blackmagic RAW. It will be able to record in full-frame 5.9K (5888×3312) at up to 30 frames per second in 16:9 aspect ratio. In a cropped APS-C mode, the S1 will be able to shoot in 4K (4128×2176) at up to 60 frames per second in 17:9 aspect ratio, and 3.5K at up to 50 frames per second in anamorphic.

The Panasonic S5 will get those same RAW recording capabilities, but without needing to have purchased any software upgrades like is the case on the S1. In both cases, 5.9K, 4K, and Anamorphic (4:3) 3.5K 12-bit RAW video data can be output over HDMI to a Blackmagic Video Assist 12G HDR to be recorded as Blackmagic RAW.

This means that Panasonic's now $1,700 full-frame camera will be able to shoot in 5.9K 12-bit RAW for no extra cost, which rivals the performance of the significantly more expensive S1H.

Panasonic will also be adding L.ClassicNeo and L.Monochrome S as photo styles to both the S1 and S1R.

Additionally, Panasonic announced the Lumix HLG Photo for Adobe Photoshop, which is a plug-in software that will allow any hybrid log gamma (HLG) photo (which is a type of HDR image) shot by any Lumix S camera to be read and edited with Adobe Photoshop. After that, Panasonic says that it is possible to view those HLG photos back as HDR photos on an HLF-corresponding monitor of an HDMI connection with a Lumix S Series camera.

Previously, Panasonic HLG photos would cease to be HLG once brought into an application like Photoshop for editing, and the only way to enjoy the wider color gamut was to view them straight out of the camera. While viewing HLG photos is still complicated, at least now there will be a way to edit them without losing the HDR nature of HLG.

The firmware updates and HLG Photo plugin for Photoshop will be available from Panasonic starting on July 12.

I know there are some people here now, a good handful of creators and of all sorts. Now let's see whether there are any people in these connected rooms, tunnels and roof-spaces?

"Heeeellloooo?












....anyone home?"

I am not afraid of being alone. But it would be useful to know what kind of toots would be wasted completely here ;-)
