Frequently asked questions

Will AI video look 'AI' to customers?

Avatar tools read as corporate/training style; stock-assembly tools read as standard social content. Neither suits premium brand films — match the tool to the format.

How do teams usually split these tools?

A common stack: Synthesia for product/help videos, InVideo or Pictory for the social calendar. Many teams start with one and add the second when a use case demands it.

What about usage rights for stock footage?

Included stock is licensed for use within your subscription, but terms differ per plan — check the vendor's license page before running paid ads.
