Adding Captions

Captioning has become a must-have for video content on social channels, with more than 50% of Millennial and GenZ watching most of their videos with subtitles on, and even more with audio muted. Here's how to add captioning in timeline:


  1. Once your video(s) are loaded into timeline, select 'Captions' located on the lefthand toolbar
  2. Select your language from the dropdown menu
  3. Click 'Create Captions'. Captioning will be laid out in a timeline view as well as a text preview. You can edit any incorrectly caught words by tapping into the correlating caption segment. 
  4. Make any edits you desire to the text. You can edit or break up text by selecting the text with your cursor, and pressing 'enter' where you would like to split the text. Or you can simply trim the caption duration by dragging on either end of the segment
  5. Select 'Style' in the bottom right of the captioning screen to make any customizations. In here, you can select styles like outlines or drop shadow, font color and type, words per caption, and any animation you would like your text to populate with
  6. Click the play button at the bottom left of the timeline to preview your full captions and style and make any final adjustments
  7. If you would ever like to revert to your original captioning, hover over the media name at the top of the captioning screen and select the refresh button that appears to reset captions to their original state
  8. Once you are satisfied with your captioning style, select 'Export' at the top right of the screen.  Choose your export settings, and select download

NOTE: Captioning is only available on videos with spoken audio! If you remove the video from the canvas, the captions will also be removed.

Export Options and SRT Files

When exporting your video content on web,  you can name your file, choose an .mov or .mp4 file type, share to Content Hub, select your frame rate, or download an SRT file. SRT files are subtitle files for video content. These are helpful to load into wherever your video is getting posted to make sure it is accessible by all audiences. Select your desired export settings, and click 'Download' when you're ready.
