This sample demonstrates how to use the Windows.Media.Transcoding API to transcode a video file in a Windows Store app. .

Or, you might convert a high-definition video file to a lower resolution. In that case, the re-encoded file might use the same codec as the original file, but it would have a different encoding profile.
