Transcoding is the process of converting a video file from one format to another. This is an essential step in ensuring that videos are viewable across a wide range of platforms and devices. Different devices and platforms often support different video formats, and transcoding allows for the adaptation of video files to meet these varying requirements.

For instance, a video originally encoded in a format suitable for desktop viewing might not be compatible with mobile devices or streaming services. By transcoding the video, it can be converted into a format that is optimized for these other platforms, ensuring a seamless viewing experience for users regardless of the device they are using.

The transcoding process involves decoding the original video file, converting it into an intermediate format, and then re-encoding it into the desired output format. This can also include adjustments to the video’s resolution, bitrate, and codec, which can help in optimizing the file size and quality for specific use cases.

Transcoding is widely used in various industries, including media production, broadcasting, and online streaming services, to ensure that content is accessible and of high quality across all viewing platforms.
