As much time as you want! On average the client spends 3-5 hours per video. We begin the process with an extensive interview about content, which usually lasts 2 hours. We need that time to get the detail straight.
From then on, we take over the process and the only time you need to contribute is giving feedback. Depending on how much feedback you give, the amount of time varies – it could be 5 minutes or 30 minutes. You can also brainstorm with the illustrator, which takes another 2 hours.
