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 ...
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.
In older designs such as MPEG-1 and H.262/MPEG-2, each B frame can only reference two frames, the one which precedes the B frame in display order and the one which follows, and all referenced pictures must be I or P frames. These constraints do not apply in newer standards H.264/MPEG-4 AVC and HEVC. Sometimes, a codec will use unidirectional B ...
HandBrake supports batch encoding through graphical user interface (GUI) and command-line interface (CLI). [10] Third-party scripts and UIs exist specifically for this purpose, such as HandBrake Batch Encoder, [11] VideoScripts, [12] and Batch HandBrake. [13] All make use of the CLI to enable queueing of several files in a single directory ...

Sixth generation NVENC implements HEVC 8K encoding at 30 FPS, HEVC B-frames and HEVC B-frames as reference (with support for each and middle modes [16]) and Alpha HEVC [17] support and provides up to 25% bitrate savings for HEVC and up to 15% bitrate savings for H.264. The initial launch of the Nvidia GeForce GTX 1650 was exempt from this ...
