Run Veo 3.1 from a node on your own fal.ai or Gemini key. $0.10 a second silent, and the cost shows before the run, not after it.
Fast is $0.10 a second without audio, $0.15 with, at 720p or 1080p. You pay the provider; Flowgen adds nothing.
Your fal.ai key, or your own Google Gemini key.
A prompt, a first frame, and optionally a closing frame.
Dialogue and sound. It is the one video model on the list that generates audio worth keeping, and the first-and-last-frame endpoint means you can draw both ends of a shot and let it fill the middle.
Audio adds half again to the bill, and a 4K second is $0.30 before audio is counted. Generate silent while you are still deciding on the cut.
The First & last frame template already wires it up.
