'''Transcoding''' is the act of converting digital content from one (usually [[lossy]]) format to another. It involves first decoding/decompressing the original data to a raw intermediate format (ie, [[PCM]] for audio or [[YUV]] for video) that mimics standard playback of the lossy content and then re-encoding this into the target format.

With regards to audio/video:Transcoding usually refers to compressing files(such as MPEG or MP3) to a lower bitrate without changing formats,Encoding(also called Rendering) usually refers to changing formats(such as AVI to MPEG or PCM to MP3).
