Domestic TV's and HDR

Geoff Boyle
 

This is a public service announcement 😊

 

I’ve just had an update to me TV and it’s added another option to the menus which is automatically switched on.

 

Having turned off all the auto or enhanced contrast, brightness and colour options and also turned off the upscale to UHD option there is now an upscale to HDR option that needs turning off.

 

There is a move from the Academy and SMPTE to introduce a simple setting that is obvious and turns ALL the enhancements off. I hope it has some effect.

 

The TV that this upload has impacted is a Philips but I believe that this is actually a LG with a few tweaks 😊 so it could have an effect on a lot more people than just the minority using Philips.

Apparently the new upscale ones will be adding AI to adjust lighting and composition based on the style of your favorite DP’s.
Soon it will be “Fix it after Post!”,  and focus pullers will be a thing of the past. Touch screen at home to choose your point of interest is the future. 
Aren’t we lucky to be living in the future already?

Are we, really?
I thought living in the future was a thing of the past...

Jokes aside, I had a discussion during IBC at the Future Trend booth with a guy from a british university working on this A1 HDR "like Dolby Vision" project. They had a 10,000 nits screen, showing 1,000, 2,000, 4,000 and 10,000 nits of the very same clip side by side. Very impressive. We ended up wondering how a 10,000 or even a 4,000 nits display should ever pass the CE certicification due its insane power consumption. Think of AA+++ refrigerator restrictions.

The bad is the enemy.

And as Geoff pointed out before, it was very clear that grading a stop higher than usual is very helpful in brighter daylight environment situations. And in the dark, you adapt yourself, your iris.

I think this attempt from the Academy does not help anything unless we see laws that require TV manufacturers to have a demo + default (!!!) setting that disables all image enhancement features, for true side by side comparisons in the electronic super store. Unfortunately the demo modes are exactly the opposite, making our holy grail cool images look like you've handed the remote control to a person with near blind cataract or green star, trying to raise contrast, brightness, saturation, with 1000Hz interpolation to show the brightest image from far. And the worsed in close stand by...

Having worked for some of these manufacturers for their demo videos, I know that business.

I think there's a lot of truth to this and we may joke about it now.

AI and Deep Learning are creating massive shifts in all sorts of areas. VFX and simulations being an obvious one but what i think could be a real consumer shift is Computational Photography - Just look at camera app on the iPhone X and XS. By recording depth we can already mess with the DOF but it's the studio lighting that rim lights subjects. To do this the AI engine (Neural Engine?) looks for the face and relights around it. Sometimes the result is quite nice too. But the phone is already very good at detecting emotions - look at the animated emojis that will real time change as you move your head and expressions. Cameras that click the shutter for you when the subject is happiest and so on.

It's a small leap to see how real time manipulation of video is not that far away and these TVs have 'improvement' sliders to totally relight what's being shown...

I don't think it's *that* difficult to get an AI to watch thousands and films and grade for you either. (collective tut'ing of most of the industry...) but there are already photo editing applications that claim this kind of thing.
