Modifying something with the features from the Storyblocks AI Toolkit consumes credits from your monthly credit balance.
AI Video Editing: Credits are consumed for editing options such as removing a background, changing a background, changing an object, and other video modifications.
AI Voiceover: Credits are consumed for generating a voiceover from text-to-speech, as well as for cloning or changing your voice within a voiceover.
The length of the modification dictates the number of credits consumed. For example, a longer voiceover generation will consume more credits than a shorter one. You will always see the total number of credits required for your edit prior to initiating it.
