About

You can edit the captions for any session or media entry directly from the Edit Session or Edit Media page, under the Captions tab. This is where you can update timings, fix text, add speakers, and manage multiple caption files - all in one place.

Editor layout

The editor has two main areas - captions panel and player panel:

Captions panel 

The captions panel displays the captions and the editing options, including the following:

• Captions drop-down list - If there is more than one caption file for the entry, you can select a different caption file from the list.



• Edit details - Click to change the caption's language, accuracy, and label.
• Search field - Type a search term and hit 'enter' on your keyboard. The results are highlighted in yellow, as shown in the image below.



• Replace - Quickly find specific words or phrases in captions and replace them with new ones.
• Add speaker - Click to add a speaker's name.
• Autoscroll  - Click to enable to auto-scroll captions as the media plays.
• Trash can icon - Click the trash can at the right of the caption line to delete that line (the trash can appears when you hover).
• Add caption - Click to add a new line of text (the +Add caption button appears when you hover).



• Timestamp - Click to modify the time.

The captions editor uses the SMPTE time format: hours, minutes, seconds, and milliseconds (hh:mm:ss,mmm). This format helps you set precise start and end points for each caption.

• Caption text - Click to modify the text.

Player panel 

The player panel displays the player, allowing you to sync the text with the audio and visuals in real-time to ensure each caption line accurately aligns with the on-screen content. 

When you click on a caption line, and the player jumps to the correct frame for the selected text as shown in the example below.
