About
The extended audio description editor lets you review and edit extended audio descriptions for your videos in KMC. If a video has more than one extended audio description file, the editor opens the one you selected.
You can easily edit the text and timing, and your changes are saved automatically. A preview mode lets you listen to the audio description during playback, so you can check how it sounds as you work.
The editor also includes helpful tools like auto-scroll, timestamp editing, and search and replace, making it easy to fine-tune extended audio descriptions and support accessible viewing.

Player panel
The player panel shows the media and plays back audio descriptions using your browser’s text-to-speech voice.
When you click an audio description cue in the panel, the player jumps to the matching timestamp to help you sync text with visual and audio content.
Editing options
When editing audio descriptions, you may also need to adjust their timing so everything stays in sync. Because audio descriptions are active from their start time until their end time, they’ll still be read out loud if a viewer skips to any moment during that period.
Therefore, after making edits, make sure to set the end timestamp to when the described moment ends, so the description doesn’t play after the scene has moved on.
