20 The artificial intelligence (AI) captions feature in Storyline is fairly new. It automatically generates captions. But as with all captions from a service, make sure you check the caption screens closely after they’re generated. Patrick’s process is to create a Storyline file for each course that includes only the video files for that course, and then he imports the VTT files into Storyline, where he can review and tweak the captions. He reviews the captions twice: once to make sure the timing works well and again to check the text for spelling errors, extra spaces, and so forth. He then saves and exports the caption as a VTT file.
Tip for version control of VTT files: Maintain version control by keeping the file name the same and overwriting previous versions. Final Review in YouTube: Upload the video and its caption file to YouTube, where you may need to make a few final adjustments — e.g., go through the file to make sure the caption screens show up as one line rather than 2.
Reminder: Ask a colleague to review the captions as well. Suggestion: Use Storyline (not YouTube) to make timing and text edits. For minor text- related changes to the captions that don’t affect the timing, you can go into the VTT file (which opens in Notepad on your computer) and make changes. For example, you can do a global search and replace (using Control/H) if needed.
