The eleven character YouTube video identifier (64 possible characters used in each position), allows for a theoretical maximum of 64 11 or around 73.8 quintillion (73.8 billion billion) unique ids. YouTube announced that it would remove video responses for being an underused feature on August 27, 2013. [96]
A main user of VP9 is Google's popular video platform YouTube, which offers VP9 video at all resolutions [52] along with Opus audio in the WebM file format, through DASH streaming. Another early adopter was Wikipedia (specifically Wikimedia Commons , which hosts multimedia files across Wikipedia's subpages and languages).

Frame rate up-conversion (FRC) is the process of increasing the temporal resolution of a video sequence by synthesizing one or more intermediate frames between two consecutive frames. A low frame rate causes aliasing, yields abrupt motion artifacts, and degrades the video quality. Consequently, the temporal resolution is an important factor ...
The resolution 192×144 is used when 144p is selected on a fullscreen YouTube video. [citation needed] YouTube 144p 144p 256×144 36,864 16:9 One tenth of 1440p. The lowest resolution on YouTube since 2013. [10] QnHD 180p 320×180 57,600 16:9 222p 222p 400×222 88,800 16:9 Used in low-resolution Facebook widescreen videos. [citation needed]
The HEVC video coding layer uses the same "hybrid" approach used in all modern video standards, starting from H.261, in that it uses inter-/intra-picture prediction and 2D transform coding. [13] A HEVC encoder first proceeds by splitting a picture into block shaped regions for the first picture, or the first picture of a random access point ...
In video streaming formats, such as H.264, fast forward algorithms use the I-frames to sample the video at faster than normal speed. [3] In streaming videos, fast-forward represents a useful search or browsing mechanism, but introduces extra network overhead when non-I-frames are transmitted in addition to the viewed I-frames and extra ...
Reference frames are frames of a compressed video that are used to define future frames. As such, they are only used in inter-frame compression techniques. In older video encoding standards, such as MPEG-2, only one reference frame – the previous frame – was used for P-frames. Two reference frames (one past and one future) were used for B ...
