When you open the Echo360 Transcript Editor, notice there is a Version drop-down list in the top left side of the screen, above the playback pane.
Every time a transcript is uploaded or edited and saved, it gets a version number. The Original version is the first transcript applied to the media. This is typically the one that was returned from the Amazon ASR service. This is shown in the below figure.
When a version is selected, the text to the right of the Version drop-down box shows WHEN that version was created/saved/uploaded, and WHO applied/edited and saved it. The version number is increased by one every time the transcript is saved or a different one is uploaded.
Among other things, the Version drop-down list allows you to select to apply a previous version if edits made to a transcript are inaccurate or inappropriate.
When you select to apply a different version than the one currently applied, you get a notification message asking you to confirm the change. You can always select other versions if necessary. Users are also able to select a previous version, edit it, then save it. A new version is created and is applied to the video/audio media. If you select the Original (or any previous version) and then save it (even without changes) a new version is created, that is identical to the one you selected. This makes it possible to track when and by whom any given transcript is applied to the media.
