What is planar YUV?
Planar formats split luma and chroma data in separate memory regions. Semi-planar formats use two planes. The first plane is the luma plane and stores the Y components. The second plane is the chroma plane and stores the Cb and Cr components interleaved.
What is NV12 color format?
NV12 is a biplanar format with a full sized Y plane followed by a single chroma plane with weaved U and V values. NV21 is the same but with weaved V and U values. The 12 in NV12 refers to 12 bits per pixel. NV24 is 24 bits per pixel with full sized chroma channel.
What is planar format?
Planar formats. Planar (or sometimes “triplanar”) formats use separate matrices for each of the 3 color components. In other words, there is one table of luminance pixel values, and two separate tables for the chrominance components. This segregated representation in memory of pixels is more convenient for video coding …
What is I420 format?
I420 consists of a Y plane, followed by a U plane, followed by a V plane. IYUV is identical to I420. Y211 is a packed format, in which Y is sampled every 2 pixels horizontally, and U and V are sampled every 4 pixels horizontally. Each macropixel is 4 bytes and contains 4 pixels.
Is YUV better than RGB?
YUV color-spaces are a more efficient coding and reduce the bandwidth more than RGB capture can. Most video cards, therefore, render directly using YUV or luminance/chrominance images. Additionally, some image compression algorithms, such as JPEG, directly support YUV, so there is no need for RGB conversion.
What is the difference between YUV and YCbCr?
YUV and YCbCr are different. YUV is an analog system. YCbCr is a digital system and widely used in video compression e.g. MPEG2.
What color format is best for Streamlabs?
Videoformat for streaming is as you say, it should stay at NV12. As for color space, use 709. It’s generally used for HD and above video. Color range (advanced tab) keep it at partial, unless changing videoformat to RGB, then use full.
What’s the advantage of using YUV color space?
YUV color-spaces are a more efficient coding and reduce the bandwidth more than RGB capture can. Most video cards, therefore, render directly using YUV or luminance/chrominance images. The most important component for YUV capture is always the luminance, or Y component.
Is YUV the same as YCbCr?
What YCbCr 422?
YCbCr is a little different, instead of rgb values it stores a brightness value (Y channel) and two chrominance channels (Cb/Cr). 444 means you get color and brightness values for every pixel (which means its in theory equivalent to RGB), 422 means you get brightness at full resolution but color at half resolution.
