FAQ

Questions, answered

How many credits does Veo 3.1 cost, and are failed videos refunded?

Veo 3.1 starts at 66 credits; the default setup costs 132 credits. Price depends on resolution and duration, and the exact cost is shown before you generate. Failed generations are refunded automatically. New accounts get 50 free credits, and Pro includes 1,000 credits per month for $9.90.

Can I use Veo 3.1 videos commercially?

Yes. Content you generate can be used in ads, online stores and social media, subject to NeoMundo's terms of service and the model provider's policies.

Does Veo 3.1 generate audio automatically?

Yes. Dialogue, ambience and sound effects are generated with the video. Put spoken lines in quotes and name the sounds you want for the most control. You cannot upload your own audio track to this model.

How do start and end frames work?

Upload one image to fix the first frame, or two images to fix both the first and the last frame. The model animates the path between them, which keeps characters and products close to your source images.

Should I choose 1080p or 4k?

Use 720p or 1080p while you iterate on the prompt, since they cost fewer credits. Switch to 4k for the final version when the clip will be shown large or edited into a high-resolution project.

How long can a Veo 3.1 clip be?

Each generation is 4, 6 or 8 seconds. For longer videos, generate several shots, reuse the last frame of one as the start frame of the next, and join them in an editor.

How is Google Veo different from other video models on NeoMundo?

Its focus is realistic AI video with sound built in. If you need 15 second clips or square 1:1 output, Kling 3.0 is a better fit; for image-only animation at 2K, try Hailuo H3.

What Veo 3.1 Does Well

Native dialogue, ambience and sound effects

Audio is generated in the same pass as the picture. Characters say the lines you write, a café has background chatter, rain hits the window and a door closes with a thud. You get an AI video with sound straight away, without recording or syncing a separate voiceover.

Three resolutions: 720p, 1080p and 4k

Use 720p to test an idea cheaply, 1080p for social feeds and 4k when the clip goes into an edit, a website hero or a large screen. The credit cost updates as you switch, so you always know the price before you press generate.

4, 6 or 8 second clips

A 4 second clip suits a single reaction or a product reveal. Six seconds fits one line of dialogue with a beat before and after. Eight seconds gives room for a short exchange between two characters or a slow camera move.

Start and end frames

Upload up to 2 images. The first becomes the opening frame, the optional second becomes the closing frame, and the model plans the motion in between. This is the most reliable way to keep a character, a product or a location consistent with your own artwork.

16:9 or 9:16 framing

Pick 16:9 for YouTube, presentations and landing pages, or 9:16 for Reels, TikTok and Shorts. Composing for the final format at generation time avoids cropping faces or text later.

What Is Veo 3.1?

Veo 3.1 is a video generation model from Google. Its standout ability is sound: it creates lifelike clips where speech, ambience and sound effects come out of the same generation as the images, so lips, footsteps and background noise line up with what happens on screen. On NeoMundo, Google Veo sits next to 12 other image and video models in one studio and one credit balance.

The model accepts a text prompt, which is required, plus up to 2 reference images. With no images it works as text to video. With one image it animates your picture from that opening frame. With two images it uses start and end frames, which lets you decide exactly where the shot begins and where it lands. It does not take video or audio uploads; everything you hear is generated from your prompt.

Output options are deliberately compact: 16:9 or 9:16, 720p, 1080p or 4k, and a duration of 4, 6 or 8 seconds. Veo 3.1 starts at 66 credits for the smallest combination, and the default setup costs 132 credits. Longer clips and higher resolutions cost more, and the studio shows the exact figure before you start.

Because each clip is short, the model works best when you think in shots rather than whole stories. Generate one moment at a time, keep the ones you like, and cut them together in your editor. Several shots can run in parallel, since each account can have up to 8 generations running at once.

How to Use Veo 3.1 on NeoMundo

  1. 01

    Step 1: 1. Open the video studio and select Veo 3.1

    Click Try Veo 3.1 at the top of this page or go to /create/video and choose the model from the list. Sign in first; new accounts receive 50 free credits.

  2. 02

    Step 2: 2. Write the shot and the spoken lines

    Describe subject, setting, camera and mood in one or two sentences, then add dialogue in quotes with who says it, for example: the barista smiles and says "Your usual?". Name the sounds you want, such as rain, traffic or a crowd, instead of hoping they appear.

  3. 03

    Step 3: 3. Add frames and pick settings

    Optionally upload a start frame, or start and end frames, as JPG, PNG or WebP up to 10 MB. Choose 16:9 or 9:16, a resolution and 4, 6 or 8 seconds. For a first pass, 720p at 4 seconds is the cheapest test.

  4. 04

    Step 4: 4. Generate, review and download

    Videos usually take 1–5 minutes. Listen with sound on, adjust the prompt if a line or sound is off, then re-run at 1080p or 4k and download the final clip.

Veo 3.1 Use Cases

Short dialogue scenes and skits

Two characters, one exchange, one location. Eight seconds is enough for a question and a punchline, and the model voices both lines with room tone included.

Product ads with a voice

Upload a product photo as the start frame, describe a presenter holding it, and write the one-sentence pitch as dialogue. Export 9:16 for paid social or 16:9 for a store banner.

Atmosphere clips for sites and edits

A rainy street, a crackling fireplace, a busy market: short loops with matching ambience fill website headers, intros and B-roll gaps without stock licensing searches.

Storyboards that move

Turn two storyboard panels into start and end frames and let the model animate the transition. Directors and agencies use this to pitch a scene before a shoot.
