Auto-generated YouTube captions have improved significantly in recent years, and the service is free. However, these video captions are still not 100 percent accurate. The process to log into your YouTube account and access the video settings makes it simple to update the captions for clarity and accuracy. Captioning your YouTube videos helps Ferris offer accessible web content and is not extremely time consuming, depending on the length of the video. A 25-minute video will usually take less than an hour to edit while a 5-minute video can take as few as 15 minutes to edit.
