(also transrating, transsizing)
Transcoding is the process of converting one digital media file format into another to make it compatible with particular devices or platforms. It can refer to reducing the file size of media files, converting between different audio or video codecs, adjusting resolution or bitrate, or changing other parameters of the media file. However, transcoding media files usually entails trade-offs between file size, quality, and compatibility.
Common types of transcoding
- Codec transcoding involves converting between different audio or video codecs, the software components that compress and decompress digital media files.
- Container format transcoding entails converting between different container formats, the file formats that store digital media files.
- Resolution transcoding refers to changing the resolution of a digital media file, which refers to the number of pixels in the image or video.
- Bitrate transcoding implies changing the bitrate of a digital media file or the amount of data used to represent each second of the media.
- Frame rate transcoding involves changing the frame rate of a digital media file, which refers to the number of frames per second in a video.
