Fox has been using 4K cameras for the football games for a while, even the ones produced in 720p. Because it makes zooming easier. So use of 4K cameras isn't sufficient to guarantee that a game isn't produced in 4K, but using 1080p cameras would obviously mean it is not (at least not for the views shown through those cameras)
Not sure exactly what you meant by zoom easier.
I'm guessing you mean digital zoom.
With 4x's the bits over 1080p they can zoom in digitally beyond optical with no degradation for the HD recording and nobody would know they did this.
Which is what ESPN's been doing for some years.
I can't imagine too many lenses that would give more superzooms for a 4k camera over what they've had for years for HD cameras.
Maybe a couple specialty lenses made just for 4k.
If Fox is using all 4k cameras to record the images of course they are better and sharper than HD.
I know from what I've read down converted 4k to 1080p looks better than 1080p native cameras.
Probably to do with the sharper and better 4k glass in the lenses.
And the bitrate that 4k is getting.
It was a wrong assumption on my part Fox was using 1080p cameras.
But it wouldn't surprise me if they are using a mix of 1080p and 4k cameras.
1080p are a lot cheaper to buy and Fox seems bent on saving a buck.
While they are lying to our faces for some time now about having "real" 4k.
Would be nice to know the complete chain from camera to upconversion.
To see where the weak link is that they are too cheap to spend the big bucks on for America viewers.
Just like today bogus ESPN claim of real 4k but like I posted it appears it's being down converted to 1080p and the sent out on a 4k channel.
And just like Fox are using some lame excuse in doublespeak about some tech reason and cost for real 4k.
Like Disney and Fox are just such financially poor companies.
The are just being cheap.
But the lying to our face and saying it's real 4k that is BS.
Still until there is more clarity I could be wrong about ESPN.
Hope someone can give us more tech details.
It might look better than Fox but since it will be NO HDR.
It can't look too much better. Probalby about the same.
They possibly might crank the bitrate higher or use better cameras and glass.
Shame though ESPN has had such a long amount of time dragging it's feet.
But they chose to not use 8k cameras. Chose not to record HDR. And who's knows if it's just going to be another 1080p scam.
Wish ONE company would be straight with the public and do 100% end to end 4k for sports.
I'd happily pay for a true 4k channel 24/7 live sports and replays and be able to record to a cloud unliimted dvr / unlimited time with no deletion and slo-mo DVR.
Thank goodness we have the Olympics for the best on the planet live sports video technology.
