The best way to use the Google Veo 3.1 AI video generator is to write one focused shot brief, make the camera move explicit, and treat audio as part of the scene instead of an afterthought. Veo 3.1 is a useful choice for cinematic clips, product visuals, and scenes where motion, sound, and output resolution all matter.
OpenVideoMaker includes Veo 3.1 and Veo 3.1 Fast. The standard variant is suited to a polished generation pass, while Fast is useful when you need to explore a concept quickly. The page also exposes reference images, aspect ratio, resolution, duration, and audio settings so you can match the generation to the final destination.
How to use Veo 3.1 for AI video
1. Define the shot before writing the prompt
Choose the subject, environment, camera position, main action, mood, and output purpose. A product reveal, a landscape establishing shot, and a social ad need different pacing and framing. Keep the first prompt centered on one visible action so you can tell whether Veo handled the brief.
2. Describe camera movement in plain language
Use phrases such as “slow dolly push from medium shot to close-up,” “locked-off wide shot,” or “gentle crane down over the table.” Put the camera move near the action it supports. If the subject walks toward the camera, explain whether the camera should stay still, track backward, or orbit around the subject.
3. Add audio direction when the scene needs sound
Veo 3.1 can interpret audio cues such as rain, room tone, footsteps, dialogue, or soft ambient music. Describe the sound and its relationship to the action: “quiet café ambience, a cup placed on the table, then a short line of dialogue.” Review the audio separately after generation because a visually strong clip still needs sound that fits the intended use.
4. Add reference images when consistency matters
Upload up to three reference images when you need a product, character, or environment to remain visually anchored. Use clear references with the important subject visible. Veo reference mode uses an 8-second duration, so select this workflow when the reference is more important than a longer clip.
5. Choose the variant and output settings
Select Veo 3.1 for the main quality pass or Veo 3.1 Fast for quicker exploration. Set the aspect ratio, resolution, duration, and audio option before generating. Veo supports outputs from 720p to 4K, but the right choice depends on where the clip will ship; a social draft does not always need the largest setting.
6. Review the picture and audio together
Check the first frame, the main camera move, subject consistency, action timing, and audio alignment. If one part fails, change only that part of the prompt. For example, make the camera instruction shorter if the framing drifts, or remove a secondary action if the subject does not complete the main one.
A practical Veo 3.1 prompt structure
Build the prompt in this order:
- Shot and camera: framing, lens feel, and movement.
- Subject: identity, material, clothing, or product traits.
- Action: one primary motion and the intended end state.
- Environment: location, time, weather, and background behavior.
- Lighting and style: source, contrast, color palette, and visual finish.
- Audio: dialogue, effects, ambience, or music direction.
For example: “Slow dolly push toward a matte black travel mug on a wooden desk at sunrise. A hand enters, lifts the mug, and steam curls into the warm window light. Clean commercial realism, shallow depth of field, soft room tone, a gentle ceramic tap on the desk, no extra objects moving.” The prompt gives Veo a clear subject, action, camera, look, and audio cue without competing storylines.
Veo 3.1 for products and social clips
For product videos, describe the material, shape, surface reflections, and the single product action you want to see. A slow rotation, lid opening, fabric movement, or close-up reveal is easier to review than several product interactions in one generation. Use a clean product reference when the exact object must remain recognizable.
For social clips, choose the ratio before generating and keep the subject inside the safe area. A vertical short needs different composition from a landscape website hero. When the output is longer than needed, trim it with the video trimmer; when the frame needs a platform-specific size, use the video resizer.
Veo 3.1 versus other AI video models
Choose Veo when cinematic camera language, audio direction, or high-resolution output is central to the brief. Use Sora 2 for narrative scenes and character moments, Seedance for reference-heavy motion workflows, or Kling when frame, image, and reference-video control needs to be explicit.
The AI video generator hub is useful when the model choice is still open. Keep the subject, action, ratio, and review criteria the same when comparing models so the result reflects the model difference rather than a changing brief.
Common Veo 3.1 prompting problems
The camera does not follow the instruction
Use one camera movement and state its direction and starting frame clearly. Replace a list of cinematic terms with a simple instruction such as “slow lateral tracking shot from left to right.” If the action is more important than the movement, simplify the camera further.
The audio does not match the picture
Write audio cues next to the event that causes them and keep the sound design short. Review the generated audio after checking the image. If the scene contains dialogue, write the line and identify who speaks; if the clip only needs atmosphere, describe the environment instead.
The reference subject changes
Use a clear reference with minimal background clutter and repeat the most important identity or product traits in the prompt. Reduce the number of moving subjects and test a shorter action before adding extra camera movement.
The clip is too large for the destination
Choose a resolution that matches the publishing surface, then trim unused time. If the final MP4 still exceeds a limit, resize or compress it with the video compressor after the visual review is complete.
FAQ
How do I use Google Veo 3.1 as an AI video generator?
Open the Veo AI video generator, write a focused shot prompt, add up to three reference images when needed, choose Veo 3.1 or Fast and the output settings, then generate and review the clip.
What is the difference between Veo 3.1 and Veo 3.1 Fast?
Veo 3.1 is the main quality-oriented option, while Veo 3.1 Fast is intended for quicker exploration. Use Fast to test a concept, then switch to the standard variant for a more polished pass when the brief is stable.
Can Veo 3.1 generate audio?
Yes. The workflow includes an audio setting, and prompts can describe dialogue, ambience, sound effects, or music direction. Review the sound and picture together before publishing.
How many reference images can I use with Veo?
You can upload up to three reference images. Veo reference mode uses an 8-second duration, so choose it when visual anchoring is more important than a longer clip.
What resolution does Veo 3.1 support?
The OpenVideoMaker page exposes 720p through 4K output options. Select the smallest resolution that keeps the subject and text readable for the intended destination, then create a larger final pass only when necessary.
