videoencoding
Video encoding is the process of converting raw video into a compressed bitstream using a video codec. The goal is to reduce data size for storage and transmission while preserving acceptable visual quality. Encoded streams are suited for playback on devices or streaming over networks and are packaged into containers that carry audio. Encoding can be lossless, which preserves all information but yields large files, or lossy, which removes some data to achieve higher compression.
In the encoding process, frames are compressed by exploiting temporal and spatial redundancies. Techniques include motion
Common codecs include MPEG-2; H.264/AVC; H.265/HEVC; AV1; VP9; and MPEG-4 Part 2. Containers such as MP4, MKV,
Rate control settings influence quality and size. Options include constant bitrate (CBR), variable bitrate (VBR), two-pass
In practice, video encoding enables distribution and archiving across platforms, from broadcast to streaming sites and
