Veo 3.1 vs Veo 3: Specs, Audio, Pricing, How to Use It

maverick — Mon, 24 Aug 2026 07:40:22 +0000

Veo 3.1 is Google's October 2025 video model. It still makes short clips, but native audio, image-to-video, and reference-image control are the real upgrades.

What Veo 3.1 actually changed

Google released Veo 3.1 and Veo 3.1 Fast on October 15, 2025, in paid preview on the Gemini API, Google AI Studio, and Vertex AI. The same model is in the Gemini app and in Flow. At launch, Google said it cost the same as Veo 3.

The clip length did not jump. A single take is still a few seconds. What changed is sound and control.

Richer native audio. Dialogue, room tone, and synced effects come with the file. You write the spoken line into the prompt. You do not start from a silent MP4.

Better image-to-video. Google says prompt adherence, picture quality, and character consistency improved when you start from a still. Better, not perfect. Faces still drift. Small logos still smear.

Ingredients to video. Up to three reference images of a character, object, or scene. That is the practical way to keep a person or a product recognizable across shots.

First and last frame. Supply a start still and an end still. Veo 3.1 generates the transition, with audio.

Scene extension. Each new clip is generated from the final second of the previous one. Google's Veo 3.1 announcement says you can go a minute or more this way. That is how you get past an 8-second take. Lite cannot extend.

A January 2026 update added native 9:16 for ingredients-to-video, so vertical social is not a crop of a 16:9 render. The same update improved 1080p and 4K upscaling on Flow, the Gemini API, and Vertex AI. Google's current Veo docs list 720p, 1080p, and 4K on Veo 3.1; Lite still has no 4K.

Length, resolution, and audio (the constraints)

These numbers decide whether the model fits the job.

	Lite	Fast	Standard
Clip length	4 / 6 / 8 s	4 / 6 / 8 s	4 / 6 / 8 s
Aspect ratio	16:9, 9:16	16:9, 9:16	16:9, 9:16
Resolution	720p, 1080p	720p, 1080p, 4K	720p, 1080p, 4K
Native audio	Yes	Yes	Yes
Scene extension	No	Yes	Yes
4K	No	Yes	Yes

A single generation is 4, 6, or 8 seconds. Eight seconds is the ceiling for one take. Ingredients (up to three refs) and first/last-frame control typically need that 8-second setting. On the API, video extension is also limited to 720p.

Audio is native. Put the spoken line and the sound in the prompt: footsteps, traffic, a kettle, a short piece of dialogue. Tiny on-screen type is still a weak spot. Do not ask Veo 3.1 to render a readable price, URL, or logo lockup.

Retries cost money. Google only bills a clip that actually generates. A clip that generates and is unusable still bills. If you need three takes to get one you can publish, you pay for three.

Lite is the cheap iteration tier: 720p or 1080p, no 4K, no extension. Fast and Standard reach 4K. Standard is the quality tier, and the one Google demonstrates for ingredients-to-video.

How to get access

Official Google paths first.

Gemini app. Consumer surface. Prompt, generate, download. Fine for a one-off. You are inside Google's consumer product, not an API.

Flow. Google's filmmaking tool. Ingredients, frames-to-video, and extend live here, with audio on those features. Use this if you are already cutting inside Google's editor.

Gemini API / Google AI Studio. Paid preview. Model IDs include veo-3.1-generate-preview, veo-3.1-fast-generate-preview, and veo-3.1-lite-generate-preview. You need a paid Gemini API key. Veo 3.1 is not on the API free tier.

Vertex AI. Same family, enterprise path. Same model, different billing account.

Those four are Google. Movby.ai is not. It is an independent aggregator. It does not own Veo.

If you just want to run a prompt in a browser without an API key, Movby.ai's Veo page runs Veo 3.1 Lite, Veo 3.1, and Veo 3.1 Quality. Modes are text-to-video, image-to-video, and ingredients-to-video on standard Veo 3.1 (up to three refs). New users get 30 free credits, no card. Typical wait on that page is about two minutes. Site-wide, videos often take 1–5 minutes.

What it costs

On Google's API, you pay per second of video with audio. Figures below are from the live Gemini API Veo 3.1 pricing table. If that page has moved, use the page, not this article.

Per second, video with audio	720p	1080p	4K
Standard	$0.40	$0.40	$0.60
Fast	$0.10	$0.12	$0.30
Lite	$0.05	$0.08	— (not supported)

Worked example: one 8-second Standard clip at 1080p is 8 × $0.40 = $3.20. The same length at Fast 1080p is $0.96. Lite 720p is $0.40. Standard 4K is $4.80. You are only charged if generation succeeds. Three successful retries of a Standard 1080p shot are $9.60 before you have a take you keep.

The Gemini API free tier does not include Veo 3.1.

Movby bills in credits, not dollars per second. Do not convert that to a per-clip USD unless you are looking at the current credit cost on the generator. Live plan prices, watermarks, and commercial terms are on Movby.ai pricing. Free-plan outputs are personal and non-commercial, and they may have watermarks. Paid plans are watermark-free and allow commercial use.

What it is good at, and what still breaks

Good. Dialogue-led shorts: a person says one or two lines, the room sounds like a room. Product-in-scene, if you feed a still of the product. Vertical social, now that 9:16 is native. Character lock across a couple of shots, if you use up to three reference images on standard Veo 3.1. First-to-last-frame for a controlled camera move.

Weak. Long-form in one shot. You will not get a 30-second hero film from a single generate. Scene extension is how you go longer, and Lite cannot do it. Tiny on-screen text. Heavy iteration: every miss that still renders is a paid miss. Prompt adherence is better than Veo 3. It is not a storyboard artist. If the prompt is vague, the model will invent blocking you did not ask for.

Treat it as an 8-second unit. Cut, extend, or regenerate. Do not plan a one-take scene that needs 20 seconds of continuous action unless you are ready to extend and accept the join.

A 4-step try

Keep this boring.

Create a Movby.ai account. New users get 30 free credits. No card.
Open the Veo 3.1 generator. Pick Veo 3.1 Lite, Veo 3.1, or Veo 3.1 Quality. Use standard Veo 3.1 if you need ingredients-to-video.
Paste a prompt, or upload a still, or (on standard Veo 3.1) up to three reference images. Set 16:9 or 9:16. Duration on this page is 8 seconds.
Generate. Wait about two minutes. Preview. Download the take you can use, or change one variable and run it again.

A prompt that actually specifies camera and sound:

Handheld medium close-up, 35mm, overcast. A woman in a navy wool coat walks toward camera on a wet Tokyo side street at dusk. Sodium street lights in the background. She glances left, then says: "The train is in four minutes." Footsteps on wet pavement, a distant crossing signal, light rain.

One subject. One camera. One spoken line. If that miss, change the line or the still. Do not rewrite it into a trailer.

FAQ

Is Veo 3.1 free?

Not on the Gemini API. Google's free tier does not include Veo 3.1; you pay per second of successful video. On Movby.ai, new users get 30 free credits with no card. Free-plan clips are personal and non-commercial, and they may have watermarks. Paid plans drop the watermark and allow commercial use.

How long are Veo 3.1 videos?

A single take is 4, 6, or 8 seconds. Eight seconds is the max for one generation. Scene extension continues from the last second of the previous clip, so you can string takes into a minute or more. Lite cannot extend. Reference images and first/last-frame shots usually need the 8-second setting.

Veo 3 vs Veo 3.1 — should I care?

Yes if you need native audio with the picture, stronger image-to-video, up to three reference images, first-and-last-frame transitions, or scene extension. Length did not increase. At launch Google priced 3.1 the same as Veo 3. Prompt adherence is better. You still cut 8-second pieces.

Can I use the clips commercially?

On Movby.ai, paid plans include commercial use; free-plan outputs are personal and non-commercial. Watermarks come off on paid plans. If you generate in the Gemini app, Flow, or the Gemini API, those products have their own terms. Read them before you run an ad. Movby does not replace Google's license.

Veo 3.1: What Actually Changes for Video Creators

maverick — Tue, 09 Jun 2026 03:00:55 +0000

You've probably seen AI video that looks decent until you try to use it. The clip has no dialogue. The character's face shifts between shots. You crop a 16:9 render to 9:16 and lose half the frame. Those aren't edge cases — they're the default friction of early AI video tools.

Google's Veo 3.1 targets those pain points directly. Released through the Gemini API in October 2025 and updated again in January 2026, the model adds synchronized audio, tighter visual consistency, and native vertical output. If you make Shorts, product demos, or social ads, here's what actually changed.

Audio arrives in the same generation

Older AI video workflows treated sound as a separate problem. You'd generate a silent clip, then layer voiceover, foley, and music in post. Veo 3.1 generates audio natively — dialogue, ambient noise, sound effects, and background music in one pass.

That matters for a 9:16 product demo where the presenter says the product name while unboxing it. You can write the line directly into your prompt: "She lifts the box and says, 'Finally, a charger that actually fits my bag.'" According to Google DeepMind's Veo documentation, the model handles lip-sync alongside the visuals.

The trade-off: short speech segments can still sound slightly off. Google notes that natural, consistent spoken audio remains an active development area. For quick social hooks, native audio is a huge time saver. For a 30-second brand spot with precise copy, plan on a few regenerations or light audio cleanup.

Reference images solve the consistency problem

The biggest practical upgrade in Veo 3.1 is Ingredients to Video — Google's term for feeding the model up to three reference images of a character, object, or scene before generation. Instead of hoping a text prompt produces the same face twice, you anchor the look with actual images.

A social media manager running a mascot across six TikTok clips can upload the same character reference each time. The January 2026 update specifically improved identity consistency, so the character holds its appearance even as backgrounds change. You can also reuse objects, textures, and settings across multiple scenes — useful for serialized content or episodic brand storytelling.

Workflow tip: create your reference images first, then write a short motion prompt. Something like "The mascot waves at camera, upbeat music plays" works better than a paragraph describing the mascot from scratch. Google suggests pairing ingredient images built in Gemini's image tools with Veo 3.1 for the cleanest results.

Native 9:16 vertical video, no cropping required

Portrait video used to mean generating landscape and cropping — which often cuts off subjects or degrades quality. As of January 2026, Veo 3.1's Ingredients to Video mode outputs native 9:16 vertical video, built for YouTube Shorts, TikTok, and Reels from the start.

You also get 16:9 landscape for standard YouTube and web placements. Combined with upscaling to 1080p and 4K — available through Flow, the Gemini API, and Vertex AI — you can draft in vertical at 720p and upscale for final delivery. The 4K option is overkill for A/B testing hooks, but it makes sense when a winning concept graduates to a paid ad.

Scene extension and frame control for longer stories

Individual Veo 3.1 clips run roughly eight seconds. That's fine for a single hook, less useful for a mini-narrative. Scene extension lets you chain clips by generating new footage from the final second of the previous one, maintaining visual continuity. Google says extended sequences can run a minute or longer — enough for a product walkthrough or a short story beat.

Two other controls worth knowing:

First and last frame: supply a starting image and an ending image, and Veo generates the transition between them with audio.
Image-to-video: upload a single start frame and describe how it should move — solid for animating a product photo or a still portrait.

Text-to-video still works for pure imagination plays — a fantasy landscape, a conceptual ad, a scene with no existing assets. Image-to-video and ingredients modes are better when brand accuracy matters.

Where to access Veo 3.1 — and what it costs

Google distributes Veo 3.1 across several surfaces: the Gemini app, YouTube Shorts, Flow, Google Vids, the Gemini API, and Vertex AI. API access runs on paid preview pricing — same rate as Veo 3, per Google's developers blog. Consumer access through Gemini and YouTube is more approachable for casual testing.

If you want to experiment without API setup or enterprise contracts, third-party platforms like Veo3AI.video offer browser-based access to Veo 3.1 models — including text-to-video, image-to-video, and ingredients modes at 720p through 4K. These services are not affiliated with Google; they route requests through the official Veo API. Credit-based pricing varies by model tier; you can compare options at Veo 3 AI Pricing.

Google also embeds SynthID watermarks in AI-generated video and offers verification tools in the Gemini app — worth knowing if you're publishing branded content and want transparency about AI origin.

Veo 3.1 doesn't replace a camera crew for long-form documentary work. For short social content, product teasers, and rapid creative testing, it closes the gaps that made AI video feel unfinished — sound, consistency, and vertical formatting. Veo 3 AI offers free credits to test a few clips if you want to see how the model handles your specific prompts before committing to a workflow.
