SDR video with a conventional gamma curve and a bit depth of 8-bits per sample has a dynamic range of about 6 stops, assuming a luminance quantisation threshold of 5% is used. [10] A threshold of 5% is used in the paper (instead of the standard 2% threshold) to allow for the typical display being dimmer than ideal.
Chart showing a conventional SDR gamma curve and the hybrid log–gamma curve. HLG uses a logarithmic curve for the upper half of the signal values, which allows for a larger dynamic range. HLG is an HDR format that uses the HLG transfer function, BT.2020 color primaries and a bitdepth of 10-bit. [8] HLG was designed to be backward compatible ...
HLG format is an HDR format that can be used for video and still images. [26] [27] It uses the HLG transfer function, Rec. 2020 color primaries, and a bit depth of 10 bits. [28] The format is backwards compatible with SDR UHDTV, but not with older SDR displays that do not implement the Rec. 2020 color standards.
HDR formats refers to formats such as HDR10, HDR10+, Dolby Vision and HLG. HDR video refers to a video encoded in an HDR format. Thoses HDR video have a greater bit depth, luminance and color volume than standard dynamic range (SDR) video which uses a conventional gamma curve. [22]
Shooting video in 30p mode gives no interlace artifacts but can introduce judder on image movement and on some camera pans. The widescreen film process Todd-AO used this frame rate in 1954–1956. [11] 48p is a progressive format and that is being trialled in the film industry. At twice the traditional rate of 24p, this frame rate attempts to ...
First is the potential for distracting motion artifacts due to interlaced video content. The solution is to either up-convert only to an interlaced BT.709 format at the same field rate, and scale the fields independently, or use motion processing to remove the inter-field motion and deinterlace, creating progressive frames. In the latter case ...
A future-use and intermediate linear RGB format using IEEE 16 bit floating point representation for each channel is also specified. For narrow range color, 10-bit per sample signals use video levels where the black level is defined as 64, achromatic gray level as 512 and the nominal peak as 940 in RGB, Y, and I encoding and 960 in Cb/Cr, and Ct ...
Some are combinations of common container formats and audio and video coding profiles, such as AVCHD and DivX formats. Although sometimes compared to DivX products, Xvid is neither a container format nor a video format, it is a software library that encodes video using specific coding profiles of the common MPEG-4 ASP video format. Those types ...
