## Capabilities

- **Cinematic video:** Hold atmosphere, costume, and camera language in one take. Veo 3.1 is the Quality route for period drama, weather, and wide scenic motion—review faces and fabric before you publish.
- **Native audio:** Motion and sound in one pass. Prompt dialogue, weather, and room tone with the action—public Veo 3.1 routes return synchronized native audio. Review speech clarity and mix before publishing.
- **First and last frame:** Lock an approved start photo and an optional end photo. Image-to-video accepts one owned JPEG, PNG, or WebP, or first plus last frame (two photos, ≤10 MB each). Three-image packs and scene extension are not on this MixVio route.
- **720p–4K delivery:** Hold fine texture for final delivery. Choose 720p, 1080p, or 4K for the same brief. Draft at a lower resolution, then re-run at 4K when edges, materials, and lighting need to hold for publish.

## How to use

1. **Choose text or owned frames:** Write a text brief, or add one owned JPEG, PNG, or WebP for image-to-video. Add a second photo as the last frame when the finish is already approved. Prefill from an Example or Key Feature if you want—nothing runs until you generate.
2. **Direct the scene and sound:** Spell out subject, action, camera language, dialogue, and ambience in plain language. Set duration (4, 6, or 8 seconds) and resolution (720p, 1080p, or 4K). Text-to-video also sets 16:9 or 9:16; image-to-video follows the start photo.
3. **Generate, review, then download:** Confirm the credit estimate, generate, then check motion and synced audio before downloading or refining the brief for another pass.

## Pricing

Public Quality quotes are flat across 4 / 6 / 8 seconds: 96 credits at 720p, 99 at 1080p, and 122 at 4K. The generator shows the exact reservation before you generate. Failed runs cost no credits.

## FAQ

### What is Veo 3.1?

Veo 3.1 is Google’s Quality-tier video model for cinematic shorts from text or owned photos. On MixVio, the reviewed public routes return one private video with synchronized native audio at selectable 720p, 1080p, or 4K for 4, 6, or 8 seconds. Image-to-video accepts a first frame, or first plus last frame.

### What is Veo 3.1 best for?

Use it for cinematic ads, hero opens, dialogue-ready scenes, and first-to-last-frame transitions where Quality delivery and native audio matter. Prefer Veo 3.1 Fast when you want the same 4/6/8 second durations at a lower credit floor without last-frame control. Prefer Seedance 2.5 when you need a longer one-take or a large reference pack, or Kling 3.0 when you need 5/10/15 second cinematic shots.

### What is the difference between Veo 3.1 and Veo 3.1 Fast?

Veo 3.1 is the Quality route: cinematic delivery, first and last frame on image-to-video, native audio, 4/6/8 seconds, and selectable 720p–4K from 96 credits. Veo 3.1 Fast keeps the same durations and resolutions on a lower-credit tier with first-frame image-to-video only. Neither public route offers three-image reference packs, video references, or scene extension. Switch to Fast in the generator when you want faster iteration.

### What inputs does Veo 3.1 support on MixVio?

Use Text to Video for a scene, camera, dialogue, and sound brief, or Image to Video with one owned JPEG, PNG, or WebP start frame (≤10 MB). Add a second owned photo as the last frame when you need a first-to-last transition. 720p or higher in 16:9 or 9:16 is recommended; other ratios may be cropped. MixVio does not hard-reject photos below 720p. Three-image packs, video or audio references, and scene extension are not on this MixVio route.

### Does Veo 3.1 generate native audio?

Yes. Public Veo 3.1 routes return video with synchronized native audio. Describe dialogue, ambience, sound effects, or music in the brief, then review speech, lip sync, and mix before publishing.

### Which ratios, resolutions, and durations are supported?

Text to Video supports 16:9 and 9:16. Image to Video follows the start photo and does not show a separate ratio picker. Each run produces one 4, 6, or 8 second video at 720p, 1080p, or 4K. The generator shows the exact compatible choices for the selected route.

### How many credits does Veo 3.1 use?

Veo 3.1 is available when your balance covers the quote. Runs reserve from 96 credits. Typical anchors on the public Quality routes: 96 credits at 720p, 99 credits at 1080p, and 122 credits at 4K, for any 4 / 6 / 8 second video. Duration does not change the quote. The generator shows the exact reservation before submission. Failed runs cost no credits.

### Is Veo 3.1 free?

Generation is not zero-credit. The exact quote depends on resolution, and failed runs cost no credits. Free delivery limits still apply when a Free-plan run is allowed.

### How does Veo 3.1 compare with Veo 3.1 Fast, Seedance 2.5, and Kling 3.0?

Veo 3.1 targets cinematic 4/6/8 second video with native audio, selectable 720p–4K, and first plus last frame on image-to-video. Veo 3.1 Fast is the lower-credit sibling without last-frame control. Seedance 2.5 emphasizes 4–30 second one-takes and packs up to 50 files at 480p–1080p. Kling 3.0 covers 5/10/15 second cinematic shots with an optional end frame. Compare live credits, inputs, duration, and audio in the comparison table before generating.

### Can I use Veo 3.1 videos commercially?
