Veo 3.1 charges the same at 720p and 1080p, so there is no saving in rendering it at 720p. Veo 3.1 Fast is cheaper at every size, and 720p is its cheapest option. Raywake shows the price before you generate and charges your prepaid USD balance only after you approve.
Which one should you use?
Pick Veo 3.1 Fast for most work: testing prompts, social clips, ads you will iterate on, and anything where a quick look decides the next step. It accepts a first frame and a first-and-last frame pair, which covers product shots that must start or end on an exact image.
Pick Veo 3.1 when the subject must stay the same across clips. It takes one to three reference images of a person, character or product and keeps them consistent in a new scene. Reference videos are 8 seconds long. At 1080p it costs the same as 720p, so final renders at 1080p cost nothing extra.
Use 4K only for the final cut. A 4K Fast clip costs about three times its 720p version.
How do frames and references work?
The request has up to three image inputs. With one image, the video starts on that frame. With two, the clip starts on the first and ends on the second, which suits reveals and packshots. On Veo 3.1, the images can instead act as references: the model builds a new scene around the person or product they show. Set the aspect ratio to match the input image to keep the frame's shape.
How to call Veo 3.1 through the API

Prompting tips
Write the sound. Both models generate audio from the prompt. Name the voices, sounds and atmosphere you want, and put any spoken line in quotes.
Keep one action per clip. Eight seconds is enough for one clear movement. For a sequence, make several clips and cut them together.
Draft with Fast, finish with what fits. Find the prompt with Veo 3.1 Fast at 720p, then render the keeper at 1080p or 4K, or move to Veo 3.1 if the subject needs references.
