Veo 3.1 AI Video Generator

The old version of this page tried to win with scale: benchmark drama, speculative pricing, broad claims about every Veo feature Google has ever shown, and a lot of language that did not map cleanly to the route people actually open on Cleep. That is the wrong shape for a useful route page. A strong page for /generate/video/veo31-video should start from two grounded layers: what Google officially documents for Veo 3.1 today, and what the current Cleep route actually exposes.

On Google's side, the current Vertex AI Veo 3.1 documentation is specific. The core 3.1 Generate and 3.1 Fast Generate capability tables describe support for text-to-video, image-to-video, prompt rewriting, and videos from the first and last frames, with 16:9 and 9:16, 720 and 1080, 24 FPS, English prompt language, and a maximum of 4 videos returned per request. Google also documents Veo's prompt strategy very clearly: the official Veo prompt guide keeps returning to framing, camera motion, style, lighting, character detail, location, action, dialogue, and sound.

On the Cleep side, this route is narrower and more practical than the full Veo family story. The current veo31-video configuration exposes text-to-video, image-to-video, first-last-to-video, and a reference-to-video path, plus multishot, up to three image inputs, a visible clip length of 8 seconds, visible resolutions of 720p and 1080p, both 16:9 and 9:16, and an estimated turnaround of roughly 3 to 5 minutes. That makes the honest reading much simpler: Veo 3.1 on Cleep is best treated as a premium short-form planning route for tightly directed 8-second clips, not as a catch-all summary of every Veo workflow Google documents across every surface.

Where Veo 3.1 is actually strong on Cleep

The strongest thing about this route is not one isolated spec. It is the combination of premium short-form quality and a more planning-heavy input surface. A lot of nearby routes give you one entrance: maybe text, maybe one image, maybe a first-last transition. Veo 3.1 on Cleep gives you several ways in without turning the page into a full editor.

The fixed 8-second shape matters more than it first seems. It forces better shot design. Instead of trying to cram a whole narrative into one generation, you can plan a clean reveal, a product moment, a fashion beat, a stylized motion plate, or a short branded transition with a clear beginning, middle, and finish. That is often exactly what premium short-form social or campaign work needs.

The route also sits in a practical production lane: 720p or 1080p, 16:9 or 9:16, estimated completion in 3 to 5 minutes, and enough image inputs to move beyond "text only." That makes it more useful for teams who already know the look they want and need the route to hold onto a brief, a still, a beginning and ending frame, or a simple multi-shot plan.

What Google officially documents, and what that means on this route

A strong Veo page should separate family-level facts from route-level facts. Google documents the Veo 3.1 family through Vertex AI and DeepMind. Cleep then exposes a narrower, very practical route on top of that. That distinction matters because it keeps the page honest when Google's broader docs mention capabilities that may be preview-only or not surfaced as a visible flow on this exact route.

Area	Official source	What it means here
Core 3.1 capabilities	The Vertex AI Veo 3.1 page lists text-to-video, image-to-video, prompt rewriting, and first/last-frame generation for the main 3.1 Generate and Fast Generate models.	The Cleep route lines up well with that core shape: text, still-image motion, and first-last planning are all central to how this page should be used.
Reference image to video	Google's broader Veo 3.1 preview documentation describes reference image to video under preview-style capability tables rather than the plain GA list.	Cleep does expose a reference-style path, but the safest reading is to treat it as a narrower workflow that should be tested carefully for your exact brief, especially when the reference carries most of the creative load.
Video extension	Google documents extend-video under preview capability tables, not as part of the basic Generate / Fast Generate list.	This Cleep route should not be described as an extend-video surface. There is no visible extend-video flow here today.
Prompt language	Google's Veo 3.1 capability table lists English as the prompt language.	Even if the article is localized, the route should still be treated as an English-prompt-first workflow for strongest results.
Clip length	Google lists 4, 6, or 8 seconds for Veo 3.1, with reference-image-to-video documented more narrowly.	Cleep currently exposes 8 seconds on this route, which reinforces the idea that this page is about high-control short-form clips, not broad duration flexibility.
Resolution	Google documents 720 and 1080 for the main 3.1 Generate / Fast Generate path.	The current route matches that visible production lane with 720p and 1080p, so there is no reason for the page to promise wider resolution coverage.
Aspect ratios	Google documents 16:9 and 9:16 for the main route families.	Cleep exposes both, which makes this route practical for both standard landscape shots and vertical social work.
Frame rate	The official Veo 3.1 docs list 24 FPS.	The route should be discussed as a cinematic short-form generation path, not as a broad frame-rate playground.
Response count	Google's capability table lists a maximum of 4 videos returned per request.	That fits the idea of directed iteration: generate a small batch, judge which shot is closest, then refine.
Prompt rewriting	The official prompt rewriter documentation says Veo 3 and 3.1 do not let you turn prompt rewriting off, and the rewritten prompt is returned only when the original prompt is fewer than 30 words long.	Prompt behavior is part of the route. You should not treat Veo 3.1 like a raw, unchanged prompt parser. It actively helps shape the input.
Prompt ingredients	The official Veo prompt guide keeps stressing framing, camera motion, style, lighting, character detail, location, action, dialogue, and sound.	That guidance is directly useful on Cleep. Better prompts are one of the biggest quality levers this route gives you.

How to choose the right Veo workflow on Cleep

Veo 3.1 is not one single interaction style. The most useful question is not "is Veo good?" but "how much of the shot do I already know?" If you know the mood but not the frame, use text-to-video. If you already own the first frame or key look, use image-to-video. If you know the opening and ending image, first-last can be much more practical than trying to describe the whole arc in one long prompt. And if your brief already has multiple beats, the route's multishot surface can help you think in production logic instead of one vague monolithic request.

Because Google documents Veo 3.1 as an English-prompt model family, the example prompts below intentionally stay in English. That is not accidental. It reflects the model's documented prompt language rather than some generic SEO choice.

Input path	Best when	What to lock clearly
Text-to-video	You are still exploring the shot and mainly know the tone, setting, and motion energy.	Framing, one key action, camera move, lighting, and visual style.
Image-to-video	The first frame already matters and the route should animate rather than re-invent the scene.	What should stay fixed, what may move, and how subtle or expressive the motion should feel.
First-last-to-video	You know the opening and ending visual states and want the route to design the bridge.	Continuity, pacing, visual identity, and what cannot drift between start and finish.
Reference-led path	A look, brand world, or character identity matters enough that text alone is not enough.	The protected visual cues: face, styling, silhouette, palette, art direction, or product setup.
Multishot	The brief has multiple beats and the clip should feel planned rather than improvised.	The order of beats, what changes between them, and the emotional or visual payoff at the end.

Prompting advice Google actually backs

One of the easiest ways to waste Veo 3.1 is to use premium video software with low-information prompts. Google's own prompt materials are unusually concrete here. The Veo prompt guide does not tell users to "be creative" in the abstract. It pushes them to specify framing, motion, style, lighting, character detail, location, action, dialogue, and sound. The separate Vertex AI prompt-rewriter docs make the same underlying point from another angle: Veo 3 and 3.1 actively rewrite prompts, and you cannot turn that behavior off.

The practical consequence is simple. If the route is important enough to use Veo 3.1, the prompt should read like shot direction, not like a lazy keyword bag. The better you map camera, motion, subject, environment, and tone, the more the route behaves like a premium planning tool instead of a generic clip generator.

• Start with the shot, not just the subject: say whether the camera is close, wide, static, pushing in, tracking, or handheld.
• Name the visual style early: if the result should feel like film noir, stop-motion, glossy commercial work, anime, or editorial luxury, say that directly.
• Write lighting and atmosphere explicitly: Google's own guidance keeps returning to light, texture, and mood because they strongly shape output.
• Use richer character detail when humans matter: specific identity cues beat generic labels.
• Describe action in sequence when the shot is dense: the more complicated the motion, the more you should direct the order of events.
• Use dialogue or sound cues on purpose: the official Veo materials talk about dialogue and sound, but this Cleep route should still be tested on your exact workflow rather than oversold as a separate visible audio-control surface.
• Keep the prompt in English: that is what Google's Veo 3.1 documentation currently lists as the prompt language.
• Remember that prompt rewriting is always on for Veo 3 and 3.1: if you want to inspect the rewritten prompt via API response, the original prompt must be fewer than 30 words.

When Veo 3.1 is the right route, and when nearby routes are easier

Veo 3.1 should not be sold as the default answer for every short video request. It is strongest when the brief benefits from its premium short-form planning surface. If the task is more about flexible short duration choices, simpler Hailuo-style iteration, or edit-first camera control, another route may fit better.

• Think in one high-value shot: this route is strongest when one scene, one reveal, one transition, or one premium ad beat carries the whole clip.
• Do not promise yourself long-form inside an 8-second route: if the brief is really multi-scene storytelling, generate beats and assemble them later.
• Use 9:16 only when the shot truly wants vertical framing: do not just crop the idea mentally and hope the route fixes composition for you.
• Reference-led work deserves extra testing: Google's own Veo docs split plain GA generation from preview-style reference-image flows, so validate the exact path you need.
• Keep route-level honesty: there is no visible extend-video flow here today, and the page should not pretend otherwise.

What we verified for this page

This rewrite is grounded in primary Google material and the live route configuration inside Cleep. The fact layer comes from the official Vertex AI Veo 3.1 capability tables, the official prompt-rewriter documentation, the official Veo prompt guide, and the current veo31-video route configuration that exposes 8-second duration, 720p and 1080p, 16:9 and 9:16, text/image/first-last/reference paths, multishot, and up to three image inputs. Unsupported benchmark numbers, speculative pricing claims, and broad future-facing promises were removed on purpose.
