Text to video
Write the scene in plain words: who is in it, where it is, what happens and how the camera moves. Veo 3.1 Lite builds the clip from that prompt alone.
Happy Wan AI Video Generator with Sound
Happy Wan is an independent online AI video generator powered by Google's Veo 3.1 Lite. Turn a text prompt or one photo into a 4, 6 or 8 second video with sound, in 720p or 1080p.

Two ways to start a shot
Text or one photo, with sound and camera control, all on one model.
Photo to video
Upload a product shot, a portrait, a drawing or a landscape. The photo is the opening frame and the prompt decides the motion, so the look stays yours.
Landscape or vertical
Make 16:9 videos for YouTube and websites, or 9:16 for TikTok, Reels and Shorts. In image mode the video can follow the shape of your photo.
Sound in every video
Veo 3.1 Lite adds an audio track while it makes the picture. Describe the sound you want in the prompt, such as rain, a crowd or footsteps.
Camera direction
Ask for a push-in, a slow orbit, a pan or a crane up. Short, specific camera notes give the steadiest results.
One price per video
A 720p video costs 30 credits and a 1080p video 35, whether it is 4, 6 or 8 seconds long. Failed runs are refunded automatically.
How to make a Happy Wan video
From idea to MP4 in four steps.
- 1

Text to video when you only have an idea, image to video when you have a picture you want to bring to life.

- 3

Generate and download
The video plays in the page when it is ready and stays in My videos, where you can download the MP4 again later.
What is Happy Wan?
Happy Wan is the name of this website, an independent AI video generator. There is no official model called Happy Wan: the name brings together two of Alibaba's video model families, HappyHorse and Wan, which many people mix up when they look for them.
The generator on this page runs Google's Veo 3.1 Lite, the lower-cost tier of Veo 3.1. It handles text-to-video and image-to-video, and it creates sound together with the picture. Happy Wan offers 4, 6 and 8 second clips in 720p or 1080p.
You don't need a Google Cloud account or an API key. Sign in with Google, add credits, and generate. Happy Wan is not affiliated with or endorsed by Google or Alibaba.
Tips for better AI videos
- One action per shot works better than a list of events. Make a longer story from several short clips.
- For image to video, use a clear, well-lit photo in the shape you want the video to be.
- Put the camera move in its own short sentence, for example: "Slow push-in toward the cup."
- To continue a scene, save the last frame of a clip and use it as the start frame of the next one.

FAQ
Frequently asked questions
Short answers about the model, the modes, credits and your files.
What is Happy Wan?
Happy Wan is an independent website where you can make AI videos from text or a photo. It is a site name, not an official model; the videos are made with Google's Veo 3.1 Lite.
Is Happy Wan the same as HappyHorse or Wan?
No. HappyHorse and Wan are video model families from Alibaba, and Happy Wan is not one of them. This site runs Google's Veo 3.1 Lite and is not affiliated with Google or Alibaba.
Which modes can I use?
Two: text to video (prompt only) and image to video (one photo becomes the first frame and your prompt sets the motion).
What photos work best for image to video?
JPG, PNG or WebP up to 10 MB. A clear, well-lit photo works best, ideally already in 16:9 or 9:16. Faces and small text can change once they start moving.
How long are the videos and what quality?
You can choose 4, 6 or 8 seconds in 720p or 1080p, as 16:9 or 9:16. In image modes you can also let the video match the shape of your photo.
How many credits does a video cost?
A 720p video costs 30 credits and a 1080p video costs 35, the same for 4, 6 or 8 seconds. The cost is shown next to the Generate button.
Is there a free trial?
New accounts don't get free credits. The smallest purchase is the $9.90 Starter Pack with 600 credits, about 20 videos at 720p, and credits you haven't used can be refunded within 7 days of purchase.
Do the videos have a watermark?
We don't add a watermark to your videos, on free credits or paid ones. You download the MP4 as the model made it.
What happens if a video fails?
If the model can't make the video, the credits for that run go back to your balance automatically. Prompts or images that break the content rules can be rejected; those runs are refunded too. A finished video you don't like still uses its credits.
Can I use the videos commercially, and can I get a refund?
Yes, under our Terms you may use the videos you make for personal and commercial purposes, as long as you have the rights to the images you upload. Credits you haven't used can be refunded in money within 7 days of purchase: an untouched pack or plan in full, a partly used one in proportion.
Who can see my prompts, images and videos?
Your uploads and videos are not shown to other visitors; they are listed only in your account under My videos. They are sent to the model provider only to make your video. For account questions, write to the support address on the Contact page.
