uudelleenmuuntaminen

Uudelleenmuuntaminen, often translated as "re-encoding" or "re-transcoding," refers to the process of converting digital data, particularly media files like audio or video, from one format or encoding to another. This can be done for various reasons, including compatibility with different devices or software, reducing file size for storage or transmission, or improving the quality of the data.

The process typically involves decoding the original file into an uncompressed or intermediate format and then re-encoding it using a different codec, bitrate, or container format. For example, a video file encoded with H.264 might be uudelleenmuunnettu to HEVC for better compression, or an audio file in MP3 could be converted to AAC for improved quality at a similar bitrate.

Common tools used for uudelleenmuuntaminen include dedicated conversion software, video editing suites, and command-line utilities. The choice of conversion parameters is crucial, as it directly impacts the balance between file size, quality, and compatibility. Improper uudelleenmuuntaminen can lead to a loss of quality or the creation of files that are not playable on intended devices. It is a fundamental operation in digital media management and distribution.
