Transcoding is a lossy procedure, introducing generation loss; however, transcoding is usually lossless if the output is possibly losslessly compressed or uncompressed. Transcoding will be the direct analog-to-analog or digital-to-digital conversion of merely one encoding to an additional, such as for movie records (e. g., BUDDY, SECAM, NTSC), audio tracks (e. g., MP3, WAV), or figure encoding.
