The solution is simply to change from NV12 to I444 or RGB in OBS's advanced settings. Though as it says, if you're streaming as well as recording, you'll get a bump in CPU usage. It's also worth noting that encoding full chroma with either of those two options will be more CPU heavy, and result in larger files.

If we want to describe a color, we usually use words like red, yellow, green or blue. That's usually enough to get the job done. If we need a very specific c.

YV12 is such a format (where chroma is shared in every 2x2 pixel block) that is supported by AviSynth. Many important codecs stored the video in YV12: MPEG-4 (x264, XviD, DivX and many others), MPEG-2 on DVDs, MPEG-1 and MJPEG. The subsampling used by YV12 is also called "4:2:0" compared to "4:2:2" which is used by YUY2 and UYVY. Dec 14, 2021 · In this article.

In the color format NV12, OBS takes 4 pixels at a time, and calculates brightness for each pixel, then calculates an average chroma information for those 4 pixels, so you lose a tiny amount of color information. The advantage is that instead of using 4 pixels x 3 bytes (r,g,b) = 12 bytes for each pixel, there's only 6 bytes used (brightness x 4.

Color Range. Color range specifies how much "range" the luma and chroma planes have, and should have no effect when the Color Format is RGB. The two settings you will most likely see are "Partial" (TV, Legal, MPEG) and "Full" (PC, Extended, JPEG). When you use the "Partial" setting, luma has a range of 16 to 235, while chroma. Color format nv12 vs rgb. Then the colour is sub-sampled into 2 x 2 squares and two 8-bit colour values (actually colour difference values) are stored for each 2 x 2 square. This requires 12 bits per pixel, hence I420 files are smaller than RGB24 files. So basically I420 has. Aug 25, 2016 · 1 1 1 1.

Kind regards.

Due to the influence of the linear part of the function, the median is close to 2.2. Similar to sRGB, the overall gamma of Rec. 709 color space is about 0.5, which results in the decoding gamma of 2.0 (1/0.5 = 2.0). ITU -R Rec. BT.709 and sRGB transfer functions. Overall decoding gamma of sRGB is closer to 2.2 than to 2.4. NV12 format is YUV 4:2:0 format ordered in memory with a Y plane first, followed by packed chroma samples in interleaved UV plane. Example: YYYYYY YYYYYY UVUVUV. RGB color format , refers to Pixel-Order RGB (byte per pixel, lower byte is Red): RGBRGBRGBRGBRGB RGBRGBRGBRGBRGB. I did some Web research, and found out that regarding NV12, YUV is defined as YCbCr color space. Color format nv12 vs rgb. The 10-bit formats also use 16 bits for each channel, with the lowest 6 bits set to zero, as shown in the following diagram. Because the 10-bit and 16-bit representations of the same YUV format have the same memory layout, it is possible to cast a 10-bit.
