Pick your starting point. You can add anything else later, and jump between stages at any time.
Write or paste a script. Generate the voice-over, then build everything on its real timing.

Use your script and an existing voice-over. Align them and review any differences.
Fastest route: bring timestamps (SRT, VTT or JSON). Validate, then go straight to storyboard.
