How to Create a Video with AI: Tools, Method and Precautions

To create a video with AI, you describe a scene in writing or start from an image, and the tool generates a clip a few seconds long, sometimes with sound. This guide covers the tools documented by their makers, a simple method for getting a good result and the precautions to take before you post anything.

What AI can do with video

AI video builds on image generation: instead of a single still, the model produces a sequence of frames that stay consistent over time. If you are new to the topic, start with our guide on how to generate images with AI, which explains the basics and how to write a prompt.

There are four main uses:

• Text to video: you describe a scene and the tool creates it.
• Image to video: you upload a photo or an illustration and the tool animates it (clouds drifting over a landscape, a drawing coming to life).
• Editing existing footage: some tools change a clip you filmed yourself.
• Sound generated with the picture: sound effects, ambience or dialogue produced alongside the video, depending on the tool.

These tools rely on multimodal models that can connect text, images, motion and sometimes sound. They mostly produce short clips: for a film lasting several minutes, you need to stitch several shots together.

The tools available

In mainstream assistants

Other assistants also offer video, according to our site profiles as of October 22, 2026:

• Grok (xAI): the Imagine feature generates images and short videos.
• Meta AI: the Meta One subscriptions launched in September 2026 mainly add more image and video generations. Meta says plans and prices vary by country; availability in Europe is not confirmed.
• Qwen Chat (Alibaba): video generation in a service described as free, with no published details on usage limits.

Dedicated creative tools

• Adobe Firefly: according to Adobe’s official page (accessed October 22, 2026), Firefly generates clips, helps edit existing footage and also creates audio. It provides access to models from Adobe and partners (including Google, OpenAI, Runway and Kling AI). A free plan gives a limited number of daily generations, and outputs carry Content Credentials showing that AI was used.
• Runway: according to its website (accessed October 22, 2026), Runway is an online platform for generating and editing video, images and audio, with its Gen-4.5 video model. A free trial is available.
• Google Flow: Google presents Flow as an AI creative studio for video and images.

Agents and multi-tool platforms

Some AI agents include video among other tasks, according to our site profiles:

• Genspark: an agent dedicated to images and videos; video uses up credits.
• Opera Neon: the Neon Make agent produces images and videos; the Standard subscription raises limits and gives access to models such as Veo 3.1 and Sora 2, as listed by Opera.
• MiniMax Agent: video with the H3 model on the Explore and Build plans; the “Classic” version shuts down on November 20, 2026, replaced by MiniMax Code.
• Poe (Quora): access to video bots from several providers, paid for in points.

Making your first video, step by step

Here is a six-step method that works whatever the tool.

1. Set the goal and the format. Vertical for a story, horizontal for a presentation? A few seconds is often enough.
2. Start from an image if you can. An image you generated, or a photo you own the rights to, gives you more control than text alone.
3. Describe the motion. This is the real difference from an image: what moves, how, and what does the camera do?
4. Generate several versions. As with images, the result changes every time.
5. Edit and add sound. Cut your best clips together in editing software, then add music or a voice-over if the tool did not produce them. Our guide to AI-generated music and voices covers what is possible and where the limits are.
6. Review before posting. Check the details, any on-screen text, and that you respect the people filmed or depicted.

Writing a good video prompt

A video prompt uses the same building blocks as an image prompt (subject, setting, style, lighting) and adds three pieces of information:

• How the subject moves: “a woman walks slowly along a beach”, “leaves are falling”.
• How the camera moves: static shot, side tracking shot, slow zoom in, aerial view.
• The soundscape, if the tool generates sound: waves, city noise, soft music.

Example: “Wide shot of a lighthouse on the Cornish coast at sunset, waves crashing on the rocks, the camera slowly moves toward the lighthouse, golden light, sound of waves and wind.”

Keep it simple: one main action per clip usually works better than a busy scene. If you are short of ideas, the prompt generator helps you structure your request.

Check yourself Your video shows the setting well, but nothing moves. What do you fix in the prompt?

You add the missing motion: what the subject does (“walks”, “turns around”), what the surroundings do (“the wind shakes the trees”) and what the camera does (“slow zoom in”). A well-described image is not enough for a video.

Realistic uses

Short AI-generated clips work well for certain uses:

• Animating a photo or an illustration for a greeting card or a message.
• Illustrating a presentation with a short mood shot at the start.
• Creating social media content: an intro shot, a transition, an animated background.
• Planning a project: visualizing a scene idea before a real shoot.

What AI video still does poorly

It is worth knowing the weak spots before you start, so you do not waste time:

• Continuity: keeping exactly the same face, clothes or setting from one clip to the next is still hard. Some tools let you start from reference images to reduce the problem.
• Fine details: hands, on-screen text, objects that warp or appear as things move.
• Physics: liquid pouring the wrong way, a shadow that does not follow, an unnatural walk.
• Lip-synced speech: when the tool generates dialogue, lip movement and the meaning of the sentences need a careful check.

These flaws vary by model and shrink with new versions, but no company promises a perfect result. Plan for several attempts and keep the best shots.

Free or paid: what to expect

Generating a video takes far more computing power than an image or a written answer. That is why companies often keep it for paid plans, or bill it in credits that run out faster than for text. At Google, for example, video in Gemini requires a Google AI subscription, while image generation is included in the free version.

Before subscribing, check three things on the official page: how many videos or credits are included, the maximum length of a clip, and whether sound is included. Where possible, start with a free trial or an entry-level plan.

To estimate what a heavy, usage-billed task might cost, the AI agent cost calculator offers a way to think in cost per task.

Precautions before posting

Consent. Animating a photo of a real person, making them speak or move, is not trivial. Ask for their consent, and never post a video that puts invented words or actions in their mouth: that is the very principle of a deepfake, used in scams and disinformation campaigns.

Rights. Terms of use differ from tool to tool, and recognizable music, characters or brands raise the same questions as with images. Our article on AI and copyright sets out the main principles as general information.

Transparency. Say that a video is AI-generated whenever it could cause confusion. AI content watermarks such as SynthID help identify it, but not every company uses them. To train your eye, our guide on how to recognize an AI-generated image offers clues that also apply to video.
