AI Assistant in Storyline 360: AI-generated Captions

Closed captions are essential for accessibility, but manually transcribing your content can be time-consuming and prone to errors. With AI Assistant in Storyline 360, you can automatically generate high-quality captions when adding audio or video content. Plus, you can review and approve captions before publishing to ensure accuracy. Read on to learn more about generating, reviewing, and approving AI-generated captions.

Generate Captions

Generating captions with AI Assistant is fast and easy. Use any of the following methods to get started.

• In Slide View, go to the Insert tab on the ribbon, then click Audio or Video from the media section. This opens your local file explorer so you can select your audio or video file.
• Drag and drop your audio or video content into the slide.
• If you have existing audio or video content in the media library, go to the View tab on the ribbon, select Media Library to open it, and then switch to the Audio or Video tab. Select your content, then click the Insert Video or Insert Audio Clip button on the lower right.

Once you’ve imported your media content, you have a few quick options to generate captions:

• Click Generate with AI in the video options under the Video Tools—or audio options under the Audio Tools—tab on the ribbon.
• Right-click your media content and hover over Closed Captions, and then click Generate.
• Right-click your media content and select Accessibility. This opens the Size and Position window to the Accessibility tab. Under Closed Captions, click the sparkle icon for Generate Captions.
• Go to the View tab on the ribbon and click Media Library. In the Audio or Video tab, select your content and then click the Generate captions button in the Captions tab on the right.
• Open the accessibility checker by clicking Accessibility Issues in the status bar at the bottom, or by going to the View tab in the ribbon and selecting Accessibility Checker. Under the All Issues tab, expand the row for Captions added, select a line item, and click the Generate captions button on the right.

When AI Assistant generates captions, a “Processing” indicator appears in the status bar on the lower right. Clicking it brings up a list of captioning jobs currently being processed. You may continue working while AI Assistant generates captions in the background.

When the caption generation completes, “Processing” changes to “Processing complete,” and each item on the list will have a “View” link next to it. Click the link to review and approve the generated captions. Note that captions are generated in the same language spoken in your audio or video content.

If caption generation fails, AI Assistant displays specific error messages to help you troubleshoot the problem.

Review and Approve Captions

To ensure accuracy, review and approve your AI-generated captions. Follow any of these methods to open the Closed Captions Editor window.

• Click Manage Captions in the video options under the Video Tools—or audio options under the Audio Tools—tab on the ribbon.
• Right-click your media content and hover over Closed Captions, and then click Manage.
• Right-click your media content and select Accessibility. This opens the Size and Position window to the Accessibility tab. Under Closed Captions, click the pencil icon for Manage Captions.
• Open the media library, select your content in the Audio or Video tab, and then click the Needs Review button under the Captions tab on the right.
• Go to the All Issues tab in the accessibility checker, expand the row for Generated captions reviewed, select a line item, and click the Review captions button on the right.
• Click the “Processing Complete” indicator in the status bar on the lower right, and then click View next to the name of your media content on the list.

This article describes how to use the closed captions editor to manually edit your captions. After reviewing the AI-generated captions, click the Approve button on the upper right. Close the window when you’re finished.

Tips:

• When you open the publishing window without approving the AI-generated captions, a link to the accessibility checker appears so you can review and approve generated captions.
• If you share a project with unapproved captions, users running the latest version of Storyline 360 can view and approve them even if they don’t have AI Assistant enabled. But if they’re using an older Storyline version without AI Assistant enabled, they won’t be able to open the project until you approve the captions and resave the file.
• Supported file formats for audio include OGG, WAV, and MP3.
• For videos, only MP4, MOV, and AVI files are supported.
