## Veo 3.1 - 8-second video with audio

The current form supports text-led or image-led video, 16:9 or 9:16, 720p, 1080p or 4K, a seed control, fixed 8-second output, first/end-frame behavior, and generated audio.

## Veo 3.1 8-second video examples

The gallery illustrates scene, dialogue, camera, time-lapse, nature, and stylized directions; it is not a benchmark or a guarantee of audio sync, fidelity, or motion.

### Photoreal Scene

### Dialogue Shot

### Dolly Zoom

### Time-Lapse

### Nature Documentary

### Stylised Sequence

## Why Veo 3.1

Veo 3.1 is a selectable paid-access video workflow whose form owns the current input, ratio, resolution, seed, frame, duration, and audio behavior. Review every returned clip.

### Text-led and image-led modes

Text mode requires a prompt. Image mode requires a source image and makes the prompt optional, so select the mode from the input you actually possess.

### First- and end-frame behavior

Image mode exposes first/end-frame support. The supplied frames guide a transition but do not guarantee exact intermediate motion or a pixel-matched ending.

### One source-image field

The schema declares one image-upload field rather than a multi-reference gallery. Do not claim several independent character or style references.

### 16:9 and 9:16 ratios

The aspect-ratio control offers landscape and vertical formats. Ratio changes framing, not prompt adherence or production readiness.

### 720p, 1080p, and 4K settings

The resolution control offers three values. Inspect delivered dimensions, compression, detail, and text after every run.

### Fixed duration, seed, and audio metadata

Model metadata declares 8 seconds, an estimated 120 seconds of processing, 200 credits, seed control, and generated audio. These remain run settings or estimates, not quality guarantees.

## Who uses Veo 3.1's 8-second clips with audio, and for what?

Video creators, marketers, storyboard artists, and product teams can use these candidate 8-second workflows to evaluate frame, ratio, resolution, seed, and audio behavior; every clip still needs review.

### Short hero-shot tests

Test one focused shot at a selected ratio and resolution, then inspect motion, text, anatomy, and audio before choosing an output.

### Dialogue and sound concepts

Use generated audio as a candidate track and check words, timing, lip movement, effects, and ambience rather than assuming synchronization.

### Opening-to-ending transitions

Provide the supported frame input to test a planned reveal or transition, then compare both ends and the path between them.

### Vertical and landscape variants

Hold the prompt and seed constant while comparing 9:16 with 16:9, then check whether cropping or composition drift changes the subject.

### Resolution comparisons

Compare 720p, 1080p, and 4K with the same setup, recording delivered dimensions, visual artifacts, and credit estimates.

### Ad and explainer concepts

Generate an 8-second candidate for downstream editing; rights, claims, brand details, captions, and final audio still require human review.

## Veo 3.1 8-second video and audio FAQ

Answers about input modes, frame behavior, ratios, resolutions, seed, fixed duration, audio metadata, paid access, credits, and review limits.

### What is Veo 3.1?

Veo 3.1 is a selectable paid-access video workflow in this app. The live form defines its text, image, frame, ratio, resolution, seed, duration, and audio behavior.

### Which input modes are available?

Text mode requires a prompt. Image mode requires one source-image field, allows an optional prompt, and exposes first/end-frame behavior.

### Does image mode accept multiple independent references?

No. The current schema declares one image-upload field. It does not establish a multi-image character, product, or style-lock workflow.

### Which ratios and resolutions can I select?

The form offers 16:9 or 9:16 and 720p, 1080p, or 4K. Verify delivered dimensions and framing after the run.

### How long is the generated clip?

Model metadata declares a fixed 8-second clip. This page does not expose a duration selector.

### How much does a run cost, and what access is required?

The catalogue marks the model as paid access and metadata lists 200 credits. Confirm the live estimate before submitting.

### What does the seed control do?

The form exposes a seed value, including random selection. Reusing a seed can aid comparison, but it does not guarantee identical output across changed inputs or model revisions.

### What does generated audio guarantee?

The metadata indicates generated audio is available. It does not guarantee correct dialogue, lip timing, music, effects, ambience, or publication readiness; review the returned track.

### What should I review before using a clip?

Review prompt adherence, identity, anatomy, object interactions, text, framing, transition behavior, resolution, and audio. Treat every clip as a candidate for post-production.

### What limits should I check before using Veo 3.1?

Generated output from Veo 3.1 can contain visual, audio, or factual errors. Review each result before publishing, and upload only material you are authorized to use. Where the form accepts a reference image, supported files are JPEG, PNG, WebP up to 10 MB each.

### What happens to the files I upload to Veo 3.1?

An upload is stored against your own account, not pooled with other people's. Deleting the account removes it: the control is in Settings under Security, the request is confirmed by email, and the erasure removes the stored objects it owns. How long anything else is kept, and which processors handle it, is stated in the privacy policy.

### Can I use what Veo 3.1 makes commercially?

Every paid plan includes a commercial licence for what Veo 3.1 makes; the free tier is for personal use.

### How does Veo 3.1 compare, and what alternatives fit a different workflow?

Veo 3.1: Use Veo 3.1 with text or first/end-frame image input, 16:9 or 9:16, 720p, 1080p or 4K, a seed control, fixed 8-second output, and generated audio. Related options are Stable Diffusion Models Hub: Compare the Stable Diffusion models and the other image and video models here: the inputs each takes, what a run costs, and the plan it needs, Wan 2.6: Use Wan 2.6 with text, one image, or up to three video references; 5-15 second choices by mode, 720p/1080p, shot type, seed, and paid access, Seedream 5 Lite: Use Seedream 5 Lite with text or up to ten JPEG, PNG or WebP references, 2K or 3K output, eight ratios, seed, output count, and paid-model access, Z-Image Turbo: Use Z-Image Turbo with a required text prompt, ten ratios, 1-49 inference steps, guidance 0-20, seed, output count, and paid-model access, Seedream 4.5: Use Seedream 4.5 with text or up to ten JPEG, PNG or WebP references, 2K or 4K output, eight ratios, seed, output count, and paid-model access, and Seedance 2 Mini: Seedance 2 Mini is the lowest-cost Seedance 2 variant - the same multimodal ByteDance model for 1080p video with native audio, text-to-video. Choose by the required input, delivered output, controls, limits, current availability, and credit cost; the related-tools section links each canonical page.
