How do we get the pen to squeak as it draws? I have the trial version for now...
Sound effects are not currently supported but many users record their own sound effect track outside VideoScribe, with or without a voiceover, and then import that mp3 into the VideoScribe voiceover track.
Adding specific sounds to specific elements in the timeline is on our roadmap: currently for this year, so that should make things easier. You may like to add it to the ideas and feature requests area so that the development team can see what you're thinking about the feature and others may add their voice.
