modify render

if video renders frame one in an image to video and frame one is the full 10 seconds or video length, we should get refunded. If the video refuses any script action, we should get a refund if that happens.  These are especially true if wan 2.5 preview and wan 2.6 already showed that they are capable of working.  Inconsistency is a business killer. budgets are real for us.  we already pay you a subscription.
