AI Video Generator

Every clip in this AI video generator starts from one of two inputs. With text alone, the model invents the whole scene from your prompt: the subject, the setting, the camera and the light. With a start image, the model treats your picture as the first frame and animates it, so a product shot, a portrait or an illustration keeps its exact look while the camera moves and the scene comes alive.

Most models accept both. Leave the image slot empty and they run text-to-video; add a picture and the same model switches to image-to-video. Two of them, Hailuo 2.3 and Vidu Q4, only work from an image, and their model cards say Image to video. Many models also take a second picture as the last frame, which lets the AI video generator plan a move between two fixed points: a closed box that ends open, or a sketch that ends as a finished room. Gemini Omni Video goes further and accepts up to seven reference images.

Uploads can be JPG, PNG or WebP files up to 10 MB. If you do not have a start frame yet, make one in the AI image generator first. A still that already has the right framing, color and subject usually gives the AI video generator a steadier start than a long text prompt, because the model no longer has to guess what the first second should look like.

Prices in this AI video generator are set per clip, in credits, and the exact figure appears on the Generate button before you press it. Three things set the price: the model, the resolution and the length. Most models bill by the second, so a 10-second clip costs twice as much as a 5-second clip at the same resolution. Veo 3.1 always renders one 8-second length, so its price changes only with the version and the resolution.

The spread is wide. At the low end, a 5-second 720p Runway clip costs 3 credits, a 6-second 480p Grok Imagine Video clip costs 4, and a 5-second 480p Wan 3.0 clip costs 10. In the middle, a 5-second 720p Kling 3.0 clip with sound costs 25 and an 8-second Veo 3.1 Fast clip at 720p costs 15. At the top, Seedance 2.5 at 1080p for 15 seconds costs 593 credits, the most expensive setting in the catalog.

A practical rule for any AI video generator: draft cheap, then finish expensive. Test the idea, the framing and the motion at 480p or 720p with a short length, and render only the keeper at 1080p or 4K. Every AI video model is paid with purchased credits; the welcome and daily check-in credits of a free account cover Z-Image pictures and video templates, not AI video models. Credit packs are listed on the pricing page, and if a generation fails, the credits for that clip return to your balance automatically.

Clip length is a short list per model rather than a slider, so one click can never turn into a surprise bill. Most families offer 5, 10 and 15 seconds. Kling 3.0 adds 3- and 8-second options, the Gemini Omni models run 4 to 10 seconds, Hailuo 2.3 offers 6 or 10 seconds, and Vidu Q4 reaches 16 seconds, the longest single clip in the AI video generator.

Resolution in the AI video generator runs from 480p drafts to 4K finals. Veo 3.1 and both Gemini Omni models are the only ones that render 4K, and MiniMax H3 offers a 2K option. Seedance 2.0 Fast and Grok Imagine Video 1.5 stop at 720p, so pick them for speed and drafts rather than for big screens. Aspect ratio matters as much: 9:16 for TikTok, Reels and Shorts, 16:9 for YouTube and websites, 1:1 for feeds. The Seedance models, MiniMax H3, PixVerse V6 and HappyHorse 1.1 also offer 21:9 for a cinematic letterbox, while Veo 3.1 and Gemini keep to 16:9 and 9:16. When you add a start image, several models follow the shape of the picture instead.

Sound is the last switch. Veo 3.1, the Seedance models, Wan 3.0, Wan 3.0 Prime and Vidu Q4 generate audio with every clip. Kling 3.0, Kling 3.0 Omni and PixVerse V6 let you turn sound on or off, and turning it off lowers the price: a 5-second 720p Kling 3.0 clip drops from 25 to 18 credits. If you plan to add your own music or voice-over in an editor, a silent clip from the AI video generator is the cheaper choice.

Veo 3.1 from Google is the default model of the AI video generator and carries the Pro badge. It comes in three versions: Lite (8 to 38 credits), Fast (15 to 45) and Quality (63 to 93). Every version renders an 8-second clip with sound in 16:9 or 9:16, from text or from a first and last frame. Use Lite and Fast to explore, and Quality when the shot has to hold up on a big screen.

Seedance from ByteDance comes in three steps. Seedance 2.5, marked New, is the top tier at 35 to 593 credits; Seedance 2.0 costs 24 to 383; Seedance 2.0 Fast costs 15 to 93 and stops at 720p. All three accept prompts up to 20,000 characters, which suits long and detailed shot descriptions, and all three include sound. Kling 3.0 from Kuaishou, marked Hot, is the most flexible on length, with five durations from 3 to 15 seconds at 720p or 1080p. Kling 3.0 Omni costs 18 to 87 credits, and Kling 3.0 Turbo, marked Fast, takes a single start image and has no sound switch.

Gemini Omni Video and Gemini Omni 1.1 Flash, both from Google, cost the same per clip: 16 credits for 4 seconds up to 32 credits for 10 seconds at 720p or 1080p, and 37 to 53 credits in 4K. That flat price makes 1080p the obvious pick on these two. Gemini Omni Video accepts up to seven reference images, the most of any model in this AI video generator, which helps when a character or a product must stay consistent.

Not every shot needs a flagship. Runway is the cheapest way to test an idea in the AI video generator: 3 credits for 5 seconds at 720p, and 8 credits for 10 seconds at 720p or 5 seconds at 1080p, from text or one start image. Grok Imagine Video from xAI, marked Fast, costs 4 to 30 credits up to 1080p, and Grok Imagine Video 1.5 costs 4 to 17 credits at 480p or 720p. Use them for storyboards, motion tests and social posts where speed matters more than polish.

The Wan line from Alibaba spans a wide range. Wan 3.0, marked New, costs 10 to 120 credits from 480p to 1080p with sound, Wan 3.0 Prime costs 16 to 189 at the same resolutions, and Wan 2.7 costs 20 to 90 at 720p or 1080p. MiniMax H3 costs 12 to 49 credits and is the only model in the AI video generator with a 2K option, PixVerse V6 runs from 540p to 1080p for 7 to 69 credits with optional sound, and HappyHorse 1.1 costs 29 to 109 credits at 720p or 1080p.

Two models exist purely to animate a picture. Hailuo 2.3 from MiniMax takes one start image and comes in Standard (8 to 13 credits) and Pro (12 to 23 credits), for 6 or 10 seconds at 768p or 6 seconds at 1080p. Vidu Q4 also takes exactly one image, renders 540p to 1080p, and offers the longest clip at 16 seconds for 9 to 77 credits. Both suit a picture that is already right and only needs motion.

A good prompt for an AI video generator reads like a shot description, not a list of keywords. Name the subject, then what it does, then how the camera moves, then the light and the mood. For example: a barista pours latte art in slow motion, close-up, the camera slowly pushes in, warm morning light through the window, shallow depth of field. One clear action per clip works better than three events packed into 5 seconds.

Camera words carry a lot of weight: dolly in, pan left, tracking shot, aerial drone shot, handheld, static tripod. Style words set the look: cinematic, documentary, stop-motion, anime, product commercial. With a start image, skip what the picture already shows and describe only the change: the steam rises, the model turns to the camera, the city lights switch on. Prompt limits differ by model, from 1,800 characters on Runway and 2,500 on Kling 3.0 to 20,000 on Seedance, Wan 3.0 and Gemini Omni, so keep short-limit models to the essentials.

Iterate on purpose. Change one thing at a time, the camera move or the light, so you learn what each word does, and keep a cheap draft model selected in the AI video generator until the motion looks right. Your clips stay in your history with their prompts, and the Copy prompt button lets you reuse a winning prompt on a premium model. For a longer ad of 15 to 60 seconds, use the AI video ad generator instead.
