A prompt is not one question. Motionbot reads your poster, renders frames when it needs to look at what it is doing, makes the edits, and checks its own work before anything lands — several turns of a reasoning model. Credits meter what that costs, so a small tweak spends a fraction of what a full build does.
Everything you have made stays yours either way. Letting a subscription lapse puts the watermark back on new video exports and makes Saved Layers read-only; nothing is deleted, and subscribing again restores it.
