Hello. I am adding captions to a video that is added to a slide. When clicking into the field to add the caption text, the video/narration stops playing and won't resume. I have tried to exit and resume the captioning and also tried closing and reopening the project file to no avail. Note, I am about 17 minutes into adding the captions. It was working fine until the point I'm at now. Could it be the length of the video? It's an hour long.
