What is the relationship between encoding and transcoding?

The relationship between encoding and transcoding is fundamentally that they represent two different processes, which is why option B is the correct choice.

Encoding is the process of converting media files into a specific format so that they can be played back in a certain way on devices or platforms. This involves taking raw video or audio data and processing it into a compressed format, making it suitable for storage, streaming, or playback.

Transcoding, on the other hand, refers to the process of converting media files from one encoded format to another. This is often necessary when a file needs to be changed to ensure compatibility with different devices or platforms, or to adjust the quality and size of the media for specific requirements.

Understanding this distinction is crucial in fields such as virtual event management, where the appropriate stream or file format might need to be selected based on a range of factors, such as the bandwidth available to participants or the requirements of different viewing devices. The other options don't accurately reflect the specific processes involved in encoding and transcoding, making them less relevant to this topic.
