Netflix shares loss may trigger a free, ad-supported streaming
Announcing its Q1 2022 results, the streaming leader revealed that it had lost 200,000 subscribers in the quarter, prompting an investor sell-off that lopped off more than a third of the SVOD’s value in after-hours trading.
Netflix co-CEO Reed Hastings then revealed in an earnings call that the streamer would roll out cheaper ad-supported versions of its service, with plans being explored “over the next year or two.”

Squeezed consumers are cutting back on streaming services to save money, while some feel there is too much content to choose from amid an avalanche of competition from rivals such as Disney and Amazon.
“Netflix’s wider problem, along with the rest of the sector is that consumers don’t have unlimited funds, and that one or two subscriptions is usually enough,” said Michael Hewson, an analyst at CMC Markets.
Netflix remains the world’s leading streaming service with more than 220 million subscribers. It is increasingly producing its own content and shows such as the Crown, Bridgerton and Squid Game have been global hits.
The firm had enjoyed uninterrupted quarterly growth in subscribers since October 2011 but on Tuesday it admitted it was losing customers to rivals, while struggling to expand due to password sharing.
It also said a decision to raise prices in key markets had cost it 600,000 subscribers in North America alone, while its exit from Russia over Ukraine lost it 700,000.

OpenVDB and NanoVDB in Unreal Engine
NanoVDB, is NVIDIA’s version of the OpenVDB library. This solution offers one significant advantage over OpenVDB, namely GPU support. It accelerates processes such as filtering, volume rendering, collision detection, ray tracing, etc., and allows you to generate and load complex special effects, all in real time.
Nevertheless, the NanoVDB structure does not significantly compress volume size. Therefore, it’s not so commonly applied in game development.

HDR and Color
https://www.soundandvision.com/content/nits-and-bits-hdr-and-color
In HD we often refer to the range of available colors as a color gamut. Such a color gamut is typically plotted on a two-dimensional diagram, called a CIE chart, as shown in at the top of this blog. Each color is characterized by its x/y coordinates.
Good enough for government work, perhaps. But for HDR, with its higher luminance levels and wider color, the gamut becomes three-dimensional.
For HDR the color gamut therefore becomes a characteristic we now call the color volume. It isn’t easy to show color volume on a two-dimensional medium like the printed page or a computer screen, but one method is shown below. As the luminance becomes higher, the picture eventually turns to white. As it becomes darker, it fades to black. The traditional color gamut shown on the CIE chart is simply a slice through this color volume at a selected luminance level, such as 50%.
Three different color volumes—we still refer to them as color gamuts though their third dimension is important—are currently the most significant. The first is BT.709 (sometimes referred to as Rec.709), the color gamut used for pre-UHD/HDR formats, including standard HD.
The largest is known as BT.2020; it encompasses (roughly) the range of colors visible to the human eye (though ET might find it insufficient!).
Between these two is the color gamut used in digital cinema, known as DCI-P3.

Photography basics: Exposure Value vs Photographic Exposure vs Il/Luminance vs Pixel luminance measurements
Also see: https://www.pixelsham.com/2015/05/16/how-aperture-shutter-speed-and-iso-affect-your-photos/
In photography, exposure value (EV) is a number that represents a combination of a camera’s shutter speed and f-number, such that all combinations that yield the same exposure have the same EV (for any fixed scene luminance).
The EV concept was developed in an attempt to simplify choosing among combinations of equivalent camera settings. Although all camera settings with the same EV nominally give the same exposure, they do not necessarily give the same picture. EV is also used to indicate an interval on the photographic exposure scale. 1 EV corresponding to a standard power-of-2 exposure step, commonly referred to as a stop
EV 0 corresponds to an exposure time of 1 sec and a relative aperture of f/1.0. If the EV is known, it can be used to select combinations of exposure time and f-number.Note EV does not equal to photographic exposure. Photographic Exposure is defined as how much light hits the camera’s sensor. It depends on the camera settings mainly aperture and shutter speed. Exposure value (known as EV) is a number that represents the exposure setting of the camera.
Thus, strictly, EV is not a measure of luminance (indirect or reflected exposure) or illuminance (incidentl exposure); rather, an EV corresponds to a luminance (or illuminance) for which a camera with a given ISO speed would use the indicated EV to obtain the nominally correct exposure. Nonetheless, it is common practice among photographic equipment manufacturers to express luminance in EV for ISO 100 speed, as when specifying metering range or autofocus sensitivity.
The exposure depends on two things: how much light gets through the lenses to the camera’s sensor and for how long the sensor is exposed. The former is a function of the aperture value while the latter is a function of the shutter speed. Exposure value is a number that represents this potential amount of light that could hit the sensor. It is important to understand that exposure value is a measure of how exposed the sensor is to light and not a measure of how much light actually hits the sensor. The exposure value is independent of how lit the scene is. For example a pair of aperture value and shutter speed represents the same exposure value both if the camera is used during a very bright day or during a dark night.
Each exposure value number represents all the possible shutter and aperture settings that result in the same exposure. Although the exposure value is the same for different combinations of aperture values and shutter speeds the resulting photo can be very different (the aperture controls the depth of field while shutter speed controls how much motion is captured).
EV 0.0 is defined as the exposure when setting the aperture to f-number 1.0 and the shutter speed to 1 second. All other exposure values are relative to that number. Exposure values are on a base two logarithmic scale. This means that every single step of EV – plus or minus 1 – represents the exposure (actual light that hits the sensor) being halved or doubled.Formulas
