In an unexpected move, Apple, Google and NBCUniversal, in partnership with SMPTE, have developed a new HDR video standard called Eclipsa Video, following the launch of Eclipsa Audio.
We are soon getting Dolby Vision 2 and HDR10+ Advanced , and this is where things get a little confusing, as Eclipsa Video will actually be administered by the HDR10+ consortium.
- "HDR10+ Technologies LLC, an industrywide consortium with more than 180 adopter companies, has been selected to administer the program for Eclipsa Video, a new open source video standard. Eclipsa Video is based upon SMPTE 2094-50, the recently developed specification created by the Society of Motion Picture and Television Engineers, with experts from Google, Apple and NBCUniversal leading this initiative," the HDR10+ alliance announced.
What is Eclipsa Video?<br>Eclipsa Video is the marketing name for the ST 2094-50 specification, which follows ST 2094-10 (Dolby Vision), ST 2094-20 and 30 (Advanced HDR), and ST 2094-40 (HDR10+).
The tech giants have not made any major announcements. The first references to ST 2094-50 began appearing last year, and then last month Google said the following:
- "Google teamed up with Apple and NBCUniversal to create a brand new technical standard (officially named SMPTE ST 2094-50, being released by the Society for Motion Picture and Television Engineers). Ultimately, this standard ensures that no matter what device you're using or what lighting you're sitting in, the video you're watching looks exactly the way the creator intended," Roshan Baliga, Group Product Manager at Google, said in May.
According to Google, it introduces two types of metadata that essentially act as an instruction manual for your display. In Google's own words:<br>Establishing a baseline (The Reference White Anchor): This acts as a consistent anchor point for the screen. It maps the brightest parts of standard content to a specific baseline, reserving all the extra brightness power strictly for the HDR video. This means standard and HDR content can finally share the same screen without throwing each other's lighting out of whack.<br>Adapting on the fly (Headroom-Adaptive Gain Curves): We are giving content creators a way to attach bespoke instructions right into the video file. If your screen has limited headroom, the video tells the display exactly how to adapt – intelligently compressing shadows and mid-tones to preserve the bright highlights without losing detail.
A threat to Dolby Vision 2 and HDR10+?<br>Eclipsa Video follows Eclipsa Audio, which is seen as an open source alternative to Dolby Atmos. As such, Eclipsa Video can likewise be viewed as an open source alternative to Dolby Vision.

The launch of Eclipsa Video raises all kinds of questions that have yet to be answered, and it is notable that Apple and Google are leading the initiative, although the two companies have started collaborated more closely in recent years on video and audio standards through the Alliance for Open Media. It is also worth noting that the third player, NBCUniversal's Peacock, is actually the first streaming service to adopt Dolby Vision 2, as announced in January . Multiple HDR formats can coexist in the market, but where does HDR10+ fit in now?
It also appears that the focus of Eclipsa Video is different, at least initially, with the rollout starting on smartphones, tablets, laptops and PCs rather than TVs, which will not be supported until later.
- "The new Eclipsa Video program will initially address smartphones, with other devices to follow. The first Eclipsa Video approved devices are expected to be introduced later this year," the HDR10+ alliance said.
- "We're excited to bring this upgraded HDR experience to the web. Support for the finalized SMPTE ST 2094-50 standard is coming in an upcoming release of Chrome," said Roshan Baliga, Google.
Although not confirmed, it seems likely that Eclipsa Video – like Eclipsa Audio – is somehow related to the rollout...
