Model notes

• Duration is set by seconds; only 6 / 8 / 10 are allowed (default 8; other values return 400).
• tier sets resolution and billing (720p / 1080p); aspect ratio inferred from size orientation (16:9 / 9:16).
• No reference_images ⇒ text-to-video; with them ⇒ image-to-video.
• First/last frame: set metadata.first_last_frame=true and pass 1–2 reference_images (1st = first frame, 2nd = last frame, order-sensitive); priced as image-to-video.
• Billed per resolution · per second: total = per-second price for the resolution × seconds.
