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 ...
HandBrake is a free and open-source transcoder for digital video files. It was originally developed in 2003 by Eric Petit to make ripping DVDs to a data storage device easier. [ 3 ]
Three types of pictures (or frames) are used in video compression: I, P, and B frames.. An I‑frame (intra-coded picture) is a complete image, like a JPG or BMP image file.. A P‑frame (Predicted picture) holds only the changes in the image from a previous frame.
[7] VideoLAN dav1d – An AV1 decoder for decoding videos with AV1 codec; Xiph.Org rav1e – An AV1 encoder written in Rust; Google libgav1 – An AV1 decoder by Google; xvc – An open source video codec, aiming to compete with h.265 and AV1. The reference implementation is released under the LGPL 2.1 and currently available in version 2.0 (as ...
The second one tells the distance between two full images (I-frames): it is the GOP size. [7] Instead of the M parameter, the maximal count of B-frames between two consecutive anchor frames can be used; this is the approach used by ffmpeg. [8] Examples: For M=3, N=12, the GOP structure is IBBPBBPBBPBB. There are 2 B-frames between two ...

Because of these drawbacks, a reliable and time periodic reference frame must be used for this technique to be efficient and useful. That reference frame is known as Intra-frame, which is strictly intra coded, so it can always be decoded without additional information. In most designs, there are two types of inter frames: P-frames and B-frames.
