Paying for AI-generated videos is necessary because the process of creating these videos involves significant computing power, which can be quite costly. To ensure the availability and sustainability of the AI video generation service, we have implemented certain limitations on the free version and introduced paid features such as extra credits.

By offering paid features, we can continue to invest in the infrastructure required to provide a seamless and high-quality video creation experience. The fees associated with the purchase of credits contribute to the maintenance and enhancement of the AI technology, allowing us to deliver innovative features and improvements over time.
