Veo 3.1 AI Video Generator

What Veo 3.1 does well

Veo 3.1 renders sound together with the picture. You get spoken lines in quotes, room tone, footsteps and effects that match the action. It follows detailed prompts closely and keeps faces and products steady through the shot. That is why it suits campaign hero shots and dialogue scenes.

Resolution and length

1080p is available for 8-second clips. 720p allows 4, 6 or 8 seconds at the same rate per second. Use it to make a shorter clip. The form switches off combinations the model does not support. Landscape and vertical formats are both available.

Cost and alternatives

Veo 3.1 is one of the most expensive video models per second. Test a new idea in a cheaper model first. Seedance 2.5 also generates sound and allows longer takes at 720p. Kling 3.0 suits silent action shots. Both pages are linked in the form.

Scripting a Veo 3.1 dialogue shot

Treat the prompt as a one-shot script. Cover who is in frame, their quoted line, how they say it and the room sound behind them. Keep one speaker per clip unless the exchange is very short. Describe the delivery, such as quietly or with a laugh. Examples: "A hotel receptionist leans over the desk and says quietly 'Your room looks over the harbor'. Lobby murmur, a bell rings." Or "An old fisherman mends a net on the dock and says 'The tide waits for nobody'. Gulls, lapping water, low sun." The Talking to camera preset suits this directly.

Settings that keep a 95-credit rate in check

Choose 720p and 4 seconds for a single line, which costs 380 credits. 1080p comes only at 8 seconds and costs 760. Frame 9:16 for one person speaking to a phone audience, 16:9 for a two-person scene. Before paying 95 per second, rehearse the same prompt on Veo 3.1 Fast. At 36 per second, the rehearsal checks wording and blocking. If nobody speaks, the gap is hard to justify. Kling 3.0 at 27 handles silent action, and MiniMax H3 at 17 gives 2K with stereo sound. Seedance 2.5 at 27 covers longer takes with dialogue at 720p.
