How Can I Add or Edit Captions to My Videos?

This is the old Help Center, which will soon be taken down. Head over to the new Help Center for up to date help articles and new feature information.

Create and Edit Video Captions

The caption editor allows users with Screencast Pro accounts to add or edit video captions. It can be used to edit captions that have been added to a video in Camtasia and then uploaded to or to add captions to a video that does not yet have any. The caption editor also has built in ADA compliance features to help you quickly discover and fix any compliance errors in your captions.

Important note: Changes made to the captions on will not be reflected in your Camtasia project.

In this tutorial we will cover:

  • Accessing the Caption Editor
  • Basic Caption Editing and ADA Compliance Features

Before getting started, there are a couple of prerequisites for using the caption editor:

  • This feature is only available to Pro account users
  • The video must be in MP4 (h.264) or WEBM (.webm) format

Accessing the Caption Editor

  1. Sign in to your Pro account and navigate to the video content you would like to caption.
  2. Click Show Details, then choose Edit Captions. The Caption Editor appears.

Basic Caption Editing and ADA Compliance Features

  1. Play your video and view existing captions using the video controls.
  2. Scrub through the video by clicking and dragging on the timeline.
  3. When the light blue playhead line touches a caption on the timeline, it selects that caption and displays it's contents in the box above it, where you can edit the caption text. A selected caption displays its duration and a character count to help with ADA compliance. Captions that do not meet ADA compliance guidelines will be red. This indicates that the caption (a) is not an acceptable duration (must be between three and seven seconds long) or (b) does not contain the proper number of characters (must be between zero and 100). The character count indicates the number of characters less than 100 the caption contains.
  4. The caption editing controls to the left of the player controls allow you to add a new caption, delete the selected caption, or split a caption at the playhead. The trash can button will delete all of the captions on the timeline. As you work, all of your changes are saved automatically, and you can always use the undo and redo buttons to go back a few steps if you make a mistake.
  5. Use the ADA Compliance Indicator to find and fix compliance errors. The indicator looks at three critical elements of ADA compliance. Click an error with a red "X" to be taken to the first error of that type on the timeline. When there are no errors of a certain type, that rule will have a green check. When all three rules are met, the indicator will display a green circle with a check mark.
  6. Extend or trim a caption by mousing over the edge and clicking and dragging the cursor. Captions shorter than three seconds or longer than seven turn red signifying that they are not ADA compliant.
  7. Use the Preview button to view your video with the captions.
  8. When you are finished working, click Save & Exit to make your captions available on the live video.
