transcoding

Digital format switching

Transcoding is converting digital media from one format or encoding to another: The video service transcodes uploads to multiple resolutions.

The process typically involves decoding the source file and re-encoding it with different parameters—compression, resolution, bitrate, or codec.

Streaming platforms transcode content to serve devices with varying capabilities and bandwidth.
