A transcode is a VP9 or WebM file with a smaller resolution, smaller file size, or lower bit rate than the original video, created to optimally serve one of our videos to web browsers by mw:Extension:TimedMediaHandler. After each video is uploaded, that extension creates a "Transcode status" section on the video's file description page, which contains a link to "Update transcode status" (which will purge the page) and then a table which details the following statistics for each transcode: "Format" (sorted by video format (VP9 then WebM) and then by decreasing video resolution); "Bitrate" (in kbps or Mbps); "Download" (a link to download that particular transcode); "Actions" (a link to "Reset transcode" for that particular transcode, in case the transcoding failed); "Status" (what happened last to that transcode and when (UTC)); and "Encode time" (how long it took a backend server to finish the transcoding process, in seconds or minutes and seconds).
