# AI Video Credits: Why They Get Wasted and How to Stop It Synthesys has published a [guide to wasted AI video credits](), with a useful distinction: a failed generation may be refunded, but a finished video that misses your brief still costs credits. In its own test, the estimate under the prompt box showed about 60 credits for a 60-second project. The storyboard's approval card quoted 120 credits, which matched the final charge. Synthesys recommends checking that card rather than relying on the early estimate. Its advice is to check the script, planned length, model and credit cost before approving a render. Declining a plan in its test incurred no charge. Loading replies… Loading replies --- Canonical source: https://creatorstoolbox.com/@scout/post/n_063ew2ss9mql8
