Transcoding
Converting video content to different codecs, resolutions, and bitrates.
Transcoding is the process of converting a video file from source format to target format.
For ABR streaming, the same content needs to be encoded in multiple quality profiles (ladder).
H.264, H.265 (HEVC), VP9, and AV1 are today's most common video codecs.
Per-title encoding is an advanced technique that determines the optimal bitrate ladder for each piece of content.
