Transsizing: a process of changing the resolution of the video, also reducing its quality and size and making it easier for ingestion over low-bandwidth connections.Transrating: a type of change where the bitrate of the video is lowered, reducing its quality and size for easier ingestion over lower-bandwidth connections.

Other types of changes that happen during transcoding are more obvious since they affect the quality of video in a more immediate and visual way. In that case, you would transcode it using the H.264 codec to get a file with a different type of compression. However, the source where you’re sending the file can only ingest files encoded with the H.264 codec. You create a video using the MPEG-4 codec (a piece of software that got its name from its main function as coder-decoder). Since the encoding of data determines the type of compression, as well as the bitrate and resolution of the video, these are the things you can change during transcoding.

Transcoding is the process of taking a video file that’s been encoded, decoding it, making some kind of alternation to it, and then encoding it again.
