Transcoding
Transcoding is the process of converting a media file (such as audio, video, or image) from one digital format or encoding to another, often involving changes in codec, resolution, bitrate, or container format. It is essential for ensuring compatibility across different devices, platforms, and network conditions, enabling efficient storage, streaming, and playback. This process typically involves decoding the original file and re-encoding it into the target format, which can impact quality and performance.
Developers should learn transcoding to handle media processing in applications like video streaming services (e.g., Netflix, YouTube), where content must be adapted for various devices and bandwidths. It is crucial for optimizing user experience by reducing buffering, supporting multiple formats, and enabling features like adaptive bitrate streaming. Knowledge of transcoding is also valuable in fields such as video editing, broadcasting, and cloud-based media workflows.
