Billing & Credits

wan2.7-videoedit: 720P=60 / 1080P=100 credits/sec; happyhorse-1.0-video-edit: 720P=90 / 1080P=160. Note: video editing is POST-PAID — no charge at submit (only a balance floor check); on success it bills the real usage (~2x output seconds); nothing is charged/refunded on failure. E.g. wan2.7-videoedit 1080P at 12s usage = 1200 credits. (x your user rate). Auto-refunded on failure.
