In accordance with the standard BT.
And bllack is 0white is I do not understand this contradiction. And one more question. Do you mean that BT. Do I understand correctly? Which standard defines this space? I can not find a a definition bt.60-15 this color space. And it is something separate.
It is basically a hack, using the limited range and gamma function of BT.
Besides the range the difference between it and sRGB is bh.601-5 length and slope of the liner section near black in the gamma curve. But the “hack” is defined by the standard REC.
From where is this information? Can you give a source? Or is it our own observations? I know virtually the person who wrote this.
He is bbt.601-5 on data of standard that I quoted above. Interestingly, in what cases is used the: DCI P3 has a bigger gamut already. I don’t know what iitu-r you’re looking for, it’s an unofficial name, but it’s a well-known one because those software packages are so popular. It seems like your question has been answered several times over already. I really doubt Sony Creative Software invented this studio levels thing.
I blame microsoft with their video for windows: Or maybe it was the original publisher of Vegas before Sony, Sonic Foundry http: They did mention Rec then known as CCIRwhich defined the standard back in https: This is a standard for high quality uncompressed digital video used in studios and video production. CCIR digital video is frequently stored on D1 digital video tapes. BTW the standard allowed for bit quantization right from the very beginning, so saying “” is a simplification, but we all know what is meant.
Again however, as foxyshadis has said post 2don’t use limited-range RGB without good reason. I thank you all for your answers! This question is important for me from a theoretical point of view.
I am doing translation.
Rec. – Wikipedia
And I have found something else. It is the same at the top end: Anything under 16 is called super black and anything over is superwhite. This is called studio-swing; when the full range from 0 to is used, this is called full range or extended range. Range or swing in this context really means excursion, as in how the signal level travels between reference black and reference white.
In 8-bit video, the minimum code value is 0 and the maximum is You would think that 0 represents pure black and represents pure white. In legal levels, video range or studio-swing, however, black is placed at code value 16 and reference white is at in 10 bit. Code values from and from are reserved as footroom and headroom.
When this system is not used and the video signal uses all code values from in 10 bit it is called full swing or extended range. Algorithms and Interfaces” by Charles A.
It was not a question. I know that REC. I completely answered the wrong question I’ve deleted the irrelevant stuff that followed. I’m not sure about the RGB question.
It might only exist to make the old analog formula continue to work out correctly.
