And seriously, well done Sunderland.

Thanks mate, I appreciate that.

Me thinks the manager should have started Hazard. Perhaps Chelsea would have won.

Anyway, now that the Arsenal is assured of Champions League, we need a world class striker.

As was mentioned in a past interview for IBC, paraphrasing…’the viewer with 4K is looking at so much more on-screen real estate’.

So, what does that ^ observation/assertion mean in visual terms?

And, at the risk of precipitating more tension for Steed with England...how can that 4K capture and presentation be of value for a sport like football (soccer), given the upcoming World Cup in Brazil…..http://www.hollywoodreporter.com/beh...lanning-700580

[Penton-Man]

Well, to illustrate, from one of the past Cine Gear expos (http://www.cinegearexpo.com/83/), just envision these people and the surroundings being world class soccer players on the pitch in the World Cup, as opposed to exposition attendees looking for freebies ….

Shot with an HD-ish camera…






Now, notice how much more picture information there is with 4K acquisition (examine and compare the borders of this image with the previous) -

Sweet!

Sport and movies are the only two things I watch on my TV, and the thought of 4K 60p footy is mouth watering. But I'm not likely to see such a thing on my TV for several years yet, in all probability.

Were Showtime using 4K cameras for those 'Super Zoom' HD replays during the boxing on Saturday night? First time I've seen it in action, very impressive if so, the amount of detail that can be extracted from such a large frame. The only trouble is, we'll need 8K cameras to do the same thing for 4K broadcasts.

Indeed . Keeping in mind towards the future, we should strive for even higher frame rate capture for 4K sports….a la about 120fps (one technical question on the far horizon is how best to deliver it to consumers, basically there are two schools of thought on that).

Anyway, why frame rate capture greater than 60fps?

Because there is scientific evidence for the value of such, e.g. http://www.bbc.co.uk/rd/blog/2013/12...oices-workshop

Heads-up Seattleites and those from surrounding burbs, I’ve been reminded thru email that for next weekend at the Cinerama theater there be 4K 3D @ 120 fps…

So, with all that ^ said and as a final reminder to tomorrow’s webcast, the Perceptual Quantizer is a most efficient way to encode HDR. But, moving onto the matter of HDR and wide color gamut (since we all love our colors ), question is, What’s the required bit depth for encoding different color gamuts when using Dolby’s perceptual curve, because different color primaries will affect the required bits.

Answer –
10 bits is needed for encoding DCI P3
12 bits is needed B.T.2020, or XYZ or ACES.
Notable is the fact that peak luminance (the amount of nits) has little impact on the required bit depth for any colorspace.

Learn more at the SMPTE webcast on Perceptual EOTF for Extended Dynamic Range Imagery tomorrow.

Katy’s study ^ however didn’t consider the use of shorter shutters (like NHK’s proposal of 1/320 sec.) with higher frame rate capture but, that practice opens up a host of other visual implications which we won’t get into right now.

So anyway, HFR certainly would help with watching horse racing on TV as, for one thing, dem legs move mighty fast and I think people know how much I love some of dem horses …https://forum.blu-ray.com/showthread...rt#post8129563

For those who missed the Derby call over the weekend …http://www.nbcsports.com/horse-racin...kentucky-derby

And, for those who missed the historical significance of the living participants involved…http://www.nbcsports.com/horse-racin...-unlikely-rise

Or, for geeks who primarily appreciate inanimate objects, namely, the world’s largest 4K video screen - http://www.techrepublic.com/article/...entucky-derby/

I would be at this if it wasn't on Mother's Day of all days. I may go to the 70mm of 2001 with Q&A with him afterwards two days before, but why they decided for ALL the showings of his new work to be on one day only (and a holiday for that matter) is beyond me.

Of course you are right. He gave Chelsea the necessary drive when he came on and norwich just couldn't get near him when he had the ball at his feet. So frustrating that I can't celebrate safety after such a stressful season. It could still go wrong although we only need 1 point from 2 home games.

Yes, but, not to forget that for years, IMAX with their DMR process has been mastering their DCPs to 22ftL for 2D content and even now there are projectors which are capable of running at that brightness. Nevertheless, people are thinking more towards laser in the future as the enabler of HDR at the commercial cinemas….if this range parameter indeed comes to fruition beyond the home environment.

Dolby proprietary solution concerns aside, to keep you up-to-date on the goings on behind the scenes, AMPAS has shot the first set of test images which have recently been mastered at different HDR levels. So the industry is serious about seeing how (and if) HDR will work with D-Cinema.

Forward thinking post professionals envisioned this next generation extended dynamic range parameter possibly coming in the future and thusly, have included it in their work for the past several years with development of ACES ( see p.10 of the quoted pdf from the Academy’s Science and Technology Council here -

Hiya Penton dude, euh man, oh well something from the '70s-'80s

Taking about HFR, how about 1 Trillion fps

Well of course there is. PC gamers once again leading the dinosaur video industry with their 120/144 Hz displays.

If 120 FPS is good for games it's good for all video.

Having a 120/144 Hz monitor doesn't mean you are actually gaming at 120 fps, it's only a refresh rate, like 240 Hz TVs. On today's best games you would need a heck of a rig to play at 120 fps, mucho gpu power needed, even at 1920x1080. Once you get 60 fps the gameplay should be smooth as silk anyways.

It's nothing like 240Hz TVs. 240Hz TVs won't accept a 240Hz input signal.

Most people using 120/144Hz monitors are PC enthusiasts and understand fully the requirements and benefits. Most are running high-end rigs and yes, gaming natively at 120/144Hz.

Using lightboost 120Hz monitors to reduce motion blur (by blinking backlight off during frame transitions) is one of the more popular fads in the last few years.

Now, notice how much more picture information there is with 4K acquisition (examine and compare the borders of this image with the previous) -

That is a pretty dramatic difference in the number of pixels between 1080p and 4K. Why does the 4K image have more picture information on the edges of the frame? The aspect ratio looks to be the same at a quick glance, but there's clearly parts of the 4K image that are cut off on all sides on the 1080p one.
