If you make videos for clients, brands, or your own social channels, the question is no longer whether Google's video models are good enough for production work. The question is which one to reach for. Veo 4 is the newer generation, and Veo 3.1 is the proven workhorse that thousands of creators built their prompt libraries around. Both are strong, both generate native audio, and both are available side by side on our platform — which means you can stop guessing and actually compare them on the same prompt.
This review covers what each model is, where they genuinely differ in daily use, how access works (Google's own products versus credit platforms like ours), a decision framework for client work, social content, and image-to-video projects, and how to migrate prompts written for Veo 3.1.
One honesty note up front: where the differences are verifiable — parameters, pricing, reference-image support — we state them plainly. Where they are not, we say so and give workflow guidance instead of invented benchmarks.
What Veo 4 and Veo 3.1 Actually Are
Both come from Google DeepMind's Veo family, text-to-video systems known for physical realism, coherent camera movement, and — since the Veo 3 generation — native audio: dialogue, ambience, and effects generated together with the picture rather than bolted on afterward.
Veo 3.1: the refined workhorse
Veo 3.1 arrived as an iteration on Veo 3, and its headline creator feature was control: it accepts a first-frame reference image and a last-frame reference image, letting you pin down where a shot starts and where it ends. If you have ever needed a product to end centered in frame, or a character to land on a specific pose for a cut, you understand why creators still love Veo 3.1.
Veo 4: the current generation
Veo 4 is the newer model. At the time of writing, the most defensible way to describe it is: the same core strengths — realism, motion coherence, native audio — carried forward on newer foundations, with a single reference-image input for guiding style and subject. You can explore it directly on our Veo 4 model page. We deliberately avoid quoting quality percentages or benchmark scores, because none have been published in a form we can verify. What we can verify is what each model exposes to you as a creator, which is what the rest of this review covers.
Quality and Control: Where Veo 4 and Veo 3.1 Differ in Practice
Here is the honest version of the quality conversation.
What we know
On our platform, both models expose nearly identical creative controls: a prompt field (up to 5,000 characters), a negative prompt, 4, 6, or 8 second durations, 720p or 1080p output, 16:9 or 9:16 aspect ratios, and an optional seed for reproducibility. Native audio comes with every generation on both.
The one concrete, verifiable control difference is reference images:
- Veo 4 accepts one reference image. Great for locking a subject, product, or visual style.
- Veo 3.1 accepts a first frame and a last frame. Great for controlling exactly how a shot begins and ends.
That difference alone decides many real projects, and we will lean on it heavily in the decision framework below.
What is less clear
Generation-to-generation "quality" claims are hard to verify from the outside. In day-to-day use, newer Veo generations have tended to feel more consistent on complex prompts — crowded scenes, multi-subject motion, tricky lighting — but that is workflow observation, not a benchmark.
How to settle it for your own work
Because both models run from the same dashboard here, the fastest answer is empirical: take one of your standard prompts, set the same seed on both models, generate a 4-second clip on each (1,000 credits per run), and compare. Ten minutes of testing on your actual subject matter beats any third-party opinion, including ours. For test material, start with our Veo prompt guide.
How to Access Veo 4 and Veo 3.1
There are two broad paths, and they suit different kinds of creators.
Google's own products
Google ships its Veo models through its own ecosystem — tools like Flow and Gemini. The upside is first-party access. The trade-offs, at the time of writing, are subscription-shaped: access tiers are bundled with broader Google plans, model availability varies by tier and region, and you generally work within Google's interface and its rules about which model version you get.
Credit-based platforms like veo4.dev
Our platform takes a different approach: one dashboard, multiple models, per-generation credits, no subscription lock-in. Veo 4 and Veo 3.1 sit next to each other in the same model picker, alongside Sora 2, Kling v2.5 Turbo Pro, Hailuo 2 and 2.3, Seedance 2.0, Wan AI 2.2, and Happy Horse 1.0. You pay credits per clip, longer clips cost more, and new users get free credits to test with — full details on our pricing page.
The practical difference for creators: on a credit platform, "Veo 4 vs Veo 3.1" is not a plan-upgrade decision. It is a dropdown. That changes how you work — you can pick per shot, not per subscription cycle.
Veo 4 vs Veo 3.1 on Our Platform: Spec Table
Here is exactly what each model exposes on veo4.dev, side by side. Credit costs are identical for both models.
| Feature | Veo 4 | Veo 3.1 |
|---|---|---|
| Clip durations | 4s / 6s / 8s | 4s / 6s / 8s |
| Resolution | 720p or 1080p | 720p or 1080p |
| Aspect ratios | 16:9 and 9:16 | 16:9 and 9:16 |
| Native audio | Yes | Yes |
| Negative prompt | Yes | Yes |
| Prompt length | Up to 5,000 characters | Up to 5,000 characters |
| Reference image input | 1 reference image | First frame + last frame |
| Seed for reproducibility | Yes (optional, 0 = random) | Yes (optional, 0 = random) |
| Credits: 4s clip | 1,000 | 1,000 |
| Credits: 6s clip | 2,000 | 2,000 |
| Credits: 8s clip | 3,000 | 3,000 |
Read that table carefully and the story becomes simple: same price, same formats, same audio — the fork in the road is how each model handles images.
Which Model Should You Use? A Decision Framework
Since credits cost the same either way, choose based on the job, not the version number.
Client work: default to Veo 4, verify with a seed test
For paid deliverables, start on Veo 4 as the current-generation model, then run one seeded A/B against Veo 3.1 on the project's hero shot before committing. A 4-second test on each model costs 2,000 credits total — cheap insurance on anything with a client's name on it. Lock the seed on whichever wins so revisions stay consistent.
Social content: Veo 4 in 9:16
For TikTok, Reels, and Shorts, Veo 4 in 9:16 at 1080p is the straightforward pick — it is even the default orientation for Veo 4 on our platform. Short 4-second clips at 1,000 credits let you batch-generate hook variations cheaply, then spend 3,000 credits on the 8-second version of the concept that earns it. Browse proven Veo 4 prompts if you want a running start.
Image-to-video with precise endpoints: Veo 3.1
This is Veo 3.1's home turf. If your shot must start on a specific frame — a product photo, a brand key visual, the last frame of a previous clip — and especially if it must also end on one, Veo 3.1's first-frame plus last-frame control is the only option between the two. Chaining clips into longer sequences (clip A's final frame becomes clip B's first frame) is a genuinely useful trick here. More on this workflow in our image-to-video guide.
Style or subject consistency from one image: Veo 4
If you have one strong reference — a character, a product, a mood frame — and you want the model to carry that look through a generated shot without dictating exact start and end frames, Veo 4's single reference-image input fits naturally.
Migrating Prompts From Veo 3.1 to Veo 4
Good news first: prompts largely carry over. Both models take the same style of natural-language direction, the same negative-prompt field, and the same 5,000-character budget. Still, a few adjustments pay off.
Re-test before you trust
Do not assume a prompt tuned over dozens of Veo 3.1 runs behaves identically on Veo 4. Re-run your five most-used prompts on Veo 4 at 4 seconds each before migrating a whole library — different generations can weight the same words differently, and this is the cheap way to find out where.
Rework frame-pinning language
Prompts written for Veo 3.1 often lean on the first/last frame images to do the compositional work, keeping the text focused on motion and mood. On Veo 4 you only have one reference image, so move endpoint instructions back into the text: describe the closing composition explicitly ("the camera settles on the bottle centered in frame") rather than relying on a last-frame upload.
Keep seeds in your notes
Seeds are not guaranteed to produce related results across different models, but within each model they remain your consistency tool. When a migrated prompt hits on Veo 4, record the seed immediately — that is your revision anchor.
Re-tune negative prompts last
Negative prompts patch a specific model's specific habits. Start your Veo 4 runs with no negative prompt, see what actually needs suppressing, and rebuild from there rather than copying over fixes for problems Veo 4 may not have.
FAQ
Is Veo 4 better than Veo 3.1?
Veo 4 is the newer generation, but "better" depends on the job. For shots that need first-frame and last-frame control, Veo 3.1 is objectively more capable because Veo 4 exposes only a single reference image. For everything else, run a seeded head-to-head on your own prompt — both models cost the same credits here, so testing is cheap.
Do Veo 4 and Veo 3.1 cost the same?
On our platform, yes: 1,000 credits for a 4-second clip, 2,000 for 6 seconds, and 3,000 for 8 seconds, identical for both models. That symmetry is deliberate — we want you choosing by capability, not price. See pricing for how credits are purchased.
Can I use images with Veo 4?
Yes. Veo 4 accepts one reference image to guide subject and style. What it does not offer is Veo 3.1's separate first-frame and last-frame inputs, so if you need to pin both endpoints of a shot, use Veo 3.1.
Do my old Veo 3.1 prompts work with Veo 4?
Mostly, yes — same natural-language prompting style, same negative-prompt field, same 5,000-character limit. Re-test your most-used prompts before trusting them on deadline work, and move any composition instructions that relied on a last-frame image back into the prompt text.
Can both models generate vertical video?
Yes. Both support 9:16 and 16:9 at 720p or 1080p. On our platform Veo 4 even defaults to 9:16, reflecting how much of its use is short-form social content.
Do both models generate audio?
Yes. Native audio — dialogue, ambience, and effects — is generated with the video on both Veo 4 and Veo 3.1. No separate audio pass is required, though many creators still replace or layer audio in the edit.
Should I still use Veo 3.1 in 2026?
Absolutely. First-frame plus last-frame control makes Veo 3.1 the stronger tool for precise image-to-video work and clip chaining. Newer does not mean strictly better when the older model has a control the newer one lacks.
The Bottom Line
Strip away the version-number drama and the Veo 4 vs Veo 3.1 decision is refreshingly simple, because on a platform where both cost the same credits, nothing forces your hand.
Use Veo 4 as your default for text-to-video work, social-first vertical content, and single-reference style guidance — it is the current generation, and it is where we would start any new project today. Keep Veo 3.1 in rotation for anything that needs exact start and end frames: product shots, storyboard-driven sequences, clip chaining. Migrate your prompt library deliberately — re-test, move endpoint language into text, rebuild negative prompts — rather than assuming parity.
And when in doubt, do what the credit model makes easy: run both on the same seed and let your own footage decide.
