Video Transcoding

Video Transcoding

1 Transcoding

With video, transcoding is the process of changing the resolution, quality, and/or encoding (parameters) of a video track, all of which involve re-encoding the entire video (and thus inevitable loss of quality).

With audio, transcoding is the process of changing the quality and/or encoding (parameters) of an audio track, both of which involve re-encoding the entire audio track (and thus inevitable loss of quality).

I am assuming here that we are working with lossy video and audio codecs, such as H.264 for video and AAC for audio.
