What is ITU R BT 709 5?
This profile encodes a reference display based on ITU-R BT. 709-5: Parameter values for the HDTV standards for production and international programme exchange. The profile encodes only the electro-optical transfer function (EOTF) of BT. 709, with a gamma of 2.4, since the PCS colorimetry is output-referred.
Is Rec709 8 bit?
709 defines an R’G’B’ encoding and a Y’CBCR encoding, each with either 8 bits or 10 bits per sample in each color channel.
What does Rec 709 stand for?
Rec. 709 is the standard camera encoding color space for HDTV with a gamut identical to sRGB. As previously stated, sRGB and Rec. 709 primaries share the same chromaticity values (and therefore the same gamut).
Is Rec 709 a codec?
709. This codec, which varies from manufacturer to manufacturer, will look the “best” straight out of the camera. Instead of applying a LUT to Log footage or extensive editing to raw footage, this footage needs very little editing in theory. It is the standard delivery color space, with full color and contrast.
What is the difference between REC 709 and BT 709?
While Rec 709 (short for Recommendation ITU-R BT. 709) is the encoding color space for HDTV, Rec 2020 is the encoding color space for UHD. The primary colors lie on the spectral locus and it is thus possible to have more saturated colors in images. (It does not mean, however, that all colors look more saturated.

High Dynamic Range (HDR) is the next generation of color clarity and realism in images and videos. Ideal for media that require high contrast or mix light and shadows, HDR preserves the clarity better than Standard Dynamic Range (SDR).
Should I use 4K or HDR?
HDR delivers a higher contrast—or larger color and brightness range—than Standard Dynamic Range (SDR), and is more visually impactful than 4K. That said, 4K delivers a sharper, more defined image. Both standards are increasingly common among premium digital televisions, and both deliver stellar image quality.
Do I need 4K HDMI cable for 4K?
