How to use the Captions Editor to edit machine-generated captions for accuracy and accessibility. See the Fix Out of Sync Closed Captions article to correct transcript syncing.

Resolution

Tip: if you don't see your captions, click the refresh link. 

Note: while the Captions Editor is recommended for editing captions/transcripts, transcript files can be edited in a TEXT editor and then resynced with the media to create the closed captions file. The Captions Editor provides a graphical interface with many features including the ability to play the media alongside the text and the ability to easily edit the timestamp for a caption line. See the Fix Out of Sync Closed Captions in MiVideo article for more information about editing and resyncing the text transcript file.

VTT Captions Note: while VTT captions are supported, the Captions Editor has a 64 character per block limit which could cause issues with editing VTT files. Please see the Unable to Edit VTT File with the Captions Editor article for more details and workarounds.

Access Captions Editor

There are multiple ways to access the captions editor depending on how the captions were added to the media and your permissions/role.

a. From the Captions and Enrich page

  1. Navigate to the Media page
  2. Actions button > Caption & Enrich > click the edit pencil icon next to the order

Note: if there is no edit icon or captions order, but the media has captions, use the next method to launch the editor (you will need to be the media owner or co-editor)

b. From the Edit Media page

  1. Navigate to My Media
  2. Click the pencil icon next to the media > click the Captions tab > click the Edit Captions button
