Open Veo 3 for a regular short scene with natural dialogue and sound effects. Open Veo 3.1 when you want to plan who speaks, the exact line, the timing, and the sound, and you will check the preview afterward. This page is the difference between Veo 3 and Veo 3.1 on KreadoAI. It stays with these two versions.
Veo 3 vs Veo 3.1 at a Glance
| Veo 3 | Veo 3.1 | |
|---|---|---|
| Why you would open it | A regular picture, with natural dialogue and sound effects | A task where the spoken line and the sound need to be planned |
| Input | Text or an image, as the current page supports | Text or an image, as the current page supports |
| Length in this workflow | 8 seconds | 8 seconds |
| Where to go next | Explore Veo 3 | Try Veo 3.1 |
Both pages describe short clips with picture, dialogue, and sound. The split is how specific the prompt needs to be, and which page you open for the job in front of you.
What's the Difference Between Veo 3 and Veo 3.1?
The useful difference is the job, not a score. Same counter. Two prompts. Open the page that matches the check you care about.
Both current pages can take text or a still. The shared settings are 1080P, 16:9 or 9:16, 8 seconds, and Generate audio. The Veo 3.1 image path also shows First & Last Frame Mode when you already have a start frame and an end frame.
The two clips below were both generated with Doubao-seedance-fast-2, 8 seconds, 16:9, with audio on. This session cannot render Veo 3 or Veo 3.1, so these clips show the two jobs. They are not those two models' output. Speech was not confirmed by listening.
Veo 3
Open Veo 3 when the picture and a natural handoff are the job. This prompt asks for the slide and the pickup, and it asks for no spoken line.
- Scene: Daylight print-shop counter.
- Action: One clerk slides one sealed kraft envelope across the wood. One customer picks it up.
- Dialogue: None.
- Sound: Paper on wood and a quiet shop. No music.
- Camera: Eye level, slight push-in.
At 1 second the clerk's hand rests on the envelope. At 4 and 7 seconds a customer's hand has reached it. Explore Veo 3.
Veo 3.1
Open Veo 3.1 when the sentence is the job. This prompt names one speaker, one line, and the moment it starts.
- Scene: Daylight print-shop counter.
- Action: One clerk slides one sealed kraft envelope across the wood into one customer's hands.
- Dialogue: The clerk, calm, at two seconds, says only: "It's ready."
- Sound: Paper on wood and a quiet shop. No music.
- Camera: Eye level, slight push-in.
The clerk's hand starts on the envelope and then lifts away. By 7 seconds the envelope is still on the counter while the customer reaches. That missed handoff is the kind of drift to check, including whether the line was actually said. Try Veo 3.1.
Which Version Should You Use?
Choose Veo 3 when you want a regular video scene. The emphasis is the picture, natural dialogue, and sound effects. Explore Veo 3.
Choose Veo 3.1 when you want to plan the speaker, the exact words, the moment they are said, and the sound, and you will watch the result before you keep it. Try Veo 3.1.
If you are still unsure, use the print-shop counter above and open the page that matches the check you care about. The picture-only prompt fits Veo 3. The prompt with "It's ready." fits Veo 3.1.
How to Choose the Right Workflow
Text-to-video fits a scene you are still describing in words. Image-to-video fits a scene that should start from a picture you already have. Dialogue and sound belong in the prompt as concrete lines: who speaks, the sentence, the tone, and the sound you want to hear.
The click-by-click dialogue prompt, the 8-second line length, and the preview checklist live in a separate guide: How to generate a Veo 3.1 video with dialogue and sound.
When you want the basic text and image flow, use How to use Veo 3. That guide covers the Veo 3 screen. It does not repeat the Veo 3.1 dialogue steps.
