Professional studios places color bars at the beginning of the video for this purposes. To view created footage in the right way (true color) you must ensure that all stages of the post production (including web hosts) doesn't introduce color error in your videos. YUV Color Range - this is video range of the resulting footage.Īll this settings applies on encoding.YUV Color Space * - this is standard ** of the color video you are working with.Color Format - this is equal to the chroma subsampling.without proper matrix) then you'll get color error ("darker" green than it actually should, and "over-bright" green vise versa). If video encoded by BT.601 and viewed as BT.709 (i.e. This is noticable on transformations: original_RGB -> compressed_YUV -> restored_RGB, when color sub-sampling take place in the middle of the process.Īdditional error introduced by gamma and different standards (BT.601, BT.709 etc.) applied to the encoding and decoding. This method is called chroma subsampling.Ĭhroma depend on luma in math calculations, so if you loss some color info - you slightly alternate luminance in some part of the result image. Higher compression of the chroma possible through U and V downscale (by horizontal or vertical). Human eye is less sensible to color than to brightness of the visual signal, thus chroma info (UV) require less detail and may be compressed higher (with loss). Special math and quantization of this channels bring to us YUV (Y - luma, like "luminance/light" U and V - chroma, like "chrominance/color"). This allow to compress color info separately from the luminance. For higher compression rate, video encoders usually use methods of representation of each video frame as 3 separate channels: one for luminosity and two for color.
