What Is YCC 422?

Are you curious to know what is YCC 422? You have come to the right place as I am going to tell you everything about YCC 422 in a very simple explanation. Without further discussion let’s begin to know what is YCC 422?

In the world of digital video and image processing, terms like “YCC 4:2:2” may seem like a foreign language to the uninitiated. However, understanding color subsampling is crucial for video professionals, content creators, and enthusiasts alike. In this blog, we will unravel the mystery of YCC 4:2:2, explaining what it is, why it matters, and its significance in the realm of digital video.

What Is YCC 422?

YCC 4:2:2 is a notation used to describe the color subsampling format in digital video. To comprehend this, let’s break down each part of the notation:

Y: Represents the luma, which stands for brightness or grayscale information in an image or video frame.
CC: Represents chroma, which denotes color information.
4:2:2: Describes the ratio of chroma information to luma information. In this case, for every four luma samples, there are two chroma samples for both the blue and red color channels.

In essence, YCC 4:2:2 indicates that there is less color information than brightness information in a video signal, and this specific ratio of chroma to luma sampling is employed.

Why Does YCC 4:2:2 Matter?

Compression Efficiency: YCC 4:2:2 is often used in video compression to reduce file sizes while maintaining high-quality video. By subsampling color information, it can save storage space and bandwidth.
Visual Quality: While there is less color information than in the 4:4:4 format (which contains equal amounts of chroma and luma), YCC 4:2:2 still provides good visual quality for most applications, making it suitable for broadcast and streaming.
Professional Video Production: YCC 4:2:2 is commonly used in professional video production settings where color accuracy is essential but storage space and data transmission efficiency are also critical.
Editing Flexibility: This format offers a balance between storage efficiency and post-production flexibility. It allows for color correction and editing while keeping file sizes manageable.
Broadcast Standards: Many broadcast and video delivery standards, such as those used in television and streaming, utilize YCC 4:2:2 to strike a balance between image quality and transmission efficiency.
Compatibility: YCC 4:2:2 is widely supported by video equipment and software, making it a practical choice for many video production workflows.

Comparing YCC 4:2:2 To Other Formats

YCC 4:4:4: In this format, there is no chroma subsampling, meaning each color channel (Y, Cb, and Cr) has the same amount of information. While it offers the highest color accuracy, it results in larger file sizes and requires more bandwidth.
YCC 4:2:0: This format subsamples both the chroma channels more aggressively, making it more storage and bandwidth-efficient but potentially sacrificing some color accuracy. It’s commonly used in consumer video formats like DVDs and Blu-rays.
YCC 4:1:1: In this format, there is even less chroma information than in 4:2:2, resulting in more significant compression and reduced color accuracy. It’s less common in professional video production but is used in some consumer video formats.

Conclusion

YCC 4:2:2 is a critical color subsampling format in the world of digital video. It strikes a balance between storage efficiency and visual quality, making it a popular choice in professional video production, broadcasting, and streaming. Understanding color subsampling formats like YCC 4:2:2 is essential for anyone working with digital video, as it directly impacts the quality, storage requirements, and compatibility of video content in various applications.

FAQ

Should I Allow YCC 4 2 2 On Xbox?

If you have that “allow 4:2:2” box checked, the Xbox will either automatically revert to non-HDR 4K signal each time you start an HDR game, or it will correctly pass the 4K HDR signal to the 4K TV, but the Elgato or other 1080p device/TV will receive no video (depends on methodology of setup which you will experience).

Should I Turn On YCC 422?

Should I use YCC 4 2 2? If you don’t have HDR/10 bit colour, then your monitor should likely already support 4:4:4, making 4:2:2 a step in the wrong direction. If your monitor does support 10 bit colour, then you may benefit from 4:2:2 as your 10 bit colour may not support 4:4:4.

What Does Pc Rgb Mean On Xbox Series S?

The Colour Space setting essentially allows you to either output all images from the console using the so-called RGB Limited colour space with values between 16 and 235 (the Series X’s Standard setting), or the full ‘PC RGB’ range of 0-255.

What Does Color Depth Do On Xbox?

Select Video fidelity & overscan > Color depth. Select the option that works best for your HDTV or monitor. Note Color depth is how much color information per pixel is sent to the TV or monitor. Color depth of 30 bits per pixel (bpp) or higher is known as “deep color.” Not all HDTVs accept deep color information.
