From Mark Gabel:
"It would be extremely advantageous to have the option to upload an audio clip and have it play all the way through so you can anticipate and know what to add next. The way it is now structured the audio stops at the point you have completed. I would have to go to my audio program or script - back and forth - to know what's coming next. This is how standard video really works. "
I've been recording in Audacity and then adding the audio and structuring the visuals around the monologue. To know what comes next I just increase the delay of my last image to x (where x is big) seconds so I can hear what comes next. Then I create the next scene and so on.
I can see myself going to a proper storyboarding process to put some more thought into it!
