99% of local broadcast content doesn't need to be more than 1080p and in SDR.
Currently, antenna is 720p SDR, digital cable is 720p/1080p SDR, satellite users have some better options, but their signal is still highly compressed. Just try watching “The Relic” during a thunderstorm.
Streaming takes the lead if you have the bandwidth, but most of us are watching 1080p SDR content and some with faster connections are watching 4K HDR. If this is your medium, then adopting a 4K HDR workflow is where you need to be if your producing content for Netflix or Amazon.
If you’re producing traditional broadcast content, 4K is nice, and you may capture in that, but you may or may not be mastering in it given time and budget constraints. Meaning, if your mastering a Game of Thrones, 4K and HDR yes, but maybe not Wheel of Fortune or The Unicorn.
If you’re producing corporate video destined for streaming and multiple uses, then you’re mastering with a much smaller budget and narrower focus, so either 2K or 4K in SDR.
If you’re making marketing videos, then you might be shooting in 8K HDR because the bosses want it that way. Think Ferrari or high end furniture.
And if you’re making Fast 9 or Shang-Chi, your shooting in 4K, 6K or 8K and mastering for 2K and 4K projectors. Sure, your mastering in HDR, but your not guaranteed to be shown in HDR.
The bottom line is that mastering in HDR is still not the norm and most video production workflows are still adapting to those demands. The XDR fills a valuable niche for a lot of video production where SDR dominates and HDR is still nascent. If your bread and butter is SDR, but customers are starting to ask for HDR, they will be wowed by the XDR and it’s good enough for all but the most demanding (GoT, $100m+ movies) customers who don’t necessarily buy those $43K Sony monitors, they just rent them during the production (show), just like they don’t buy Panavision lenses and ARRI Alexa 65s, they rent them.
The XDR provides a solution for those caught in the middle. It’s not perfect, but it is cost effective and just in reach for those that need to step up to HDR mastering and deliverables. Anyone lamenting a cheaper option from Apple, I agree that they aren’t filling that hole and they should. If you think the XDR is just some expensive gimmick, you have lost the plot.
