Pexo turns a still image and a plain-language description into a finished, ready-to-post video.
Summary
This guide shows how to generate a video from a still image and a plain-language description with Pexo, the AI video agent. You describe what you want in normal words, add a reference image if you have one, and Pexo builds a finished, ready-to-post clip. It covers what to prepare, a description formula that gets you a usable first result, a four-step walkthrough inside Pexo, the mistakes that ruin a first try, pro tips, and a short FAQ. Written for marketers, creators, and small business owners who want video without prompt syntax or a timeline editor.
Intro
Pexo is the AI video agent that takes a still image and a plain description and hands you a finished video after one conversation. No prompts. Just talk. You say what you want in everyday language, drop in a photo if you have one, and Pexo works out the motion, pacing, and sound for you.
The old path to the same result was slow. You would write model-specific prompt syntax, stitch clips on a timeline, and hope the pieces matched. This tutorial skips that. In four steps you go from an image and a sentence to a video you can post, and the real skill is not the clicking. It is writing a description Pexo can act on. That is where most of this guide focuses.
What You Need Before You Start
You do not need editing skills or a script. You need three things: an idea you can put into words, an optional reference image, and a Pexo account.
The image is optional but useful when you already have a product photo, a brand shot, or a scene you want animated. If you do not have one, you can generate the still directly with Pexo's text-to-image and carry it into the same conversation without leaving the app. A higher-resolution image gives the motion more detail to work with, so use the sharpest version you have.
How to Write a Description Pexo Can Work With
The description does more work than the image. "Make a cool product video" gives Pexo almost nothing to aim at. A description that produces a usable first result names six things:
[length] + [format] + [subject] + [motion] + [light and mood] + [audio]
This is not prompt engineering. There is no syntax, no parameters, no negative-prompt tricks. It is a plain sentence, the kind you would text a colleague. Naming these six things just gives Pexo a clearer target. You do not need every slot filled every time, but the more you specify, the closer the first result lands. Here is the same formula across four common jobs:
| Job | Description you give Pexo |
|---|---|
| Product ad | 15-second vertical ad for my ceramic mug. Slow zoom on the handle, warm morning light, soft lo-fi music. |
| Social teaser | 20-second Instagram Reel introducing my candle line. Cozy autumn colors, gentle camera drift, calm background music. |
| Real estate | 30-second horizontal walkthrough of a modern living room. Smooth pan left to right, bright daylight, light ambient music. |
| Food clip | 10-second square shot of a pancake stack. Syrup pouring in slow motion, tight close-up, upbeat music. |
Notice what each line has in common: a concrete subject, a named camera move, and a mood. Vague adjectives like "nice" or "professional" get you generic output.
The fastest way to feel the difference is to see a weak line next to a rewrite. Both descriptions below ask for the same video. Only one gives Pexo enough to aim at.
| Weak description (avoid) | Rewritten with the formula |
|---|---|
| Make a cool video for my coffee shop. | 15-second vertical clip for my coffee shop. Slow pan across a latte on a wooden counter, warm morning light, soft acoustic music. |
| A professional ad for my sneakers. | 10-second square ad for my white sneakers. Quick spin on a plain background, bright studio light, an upbeat track. |
| Something for my candle launch. | 20-second Instagram Reel for my candle launch. Gentle camera drift over three lit candles, cozy autumn colors, calm background music. |
Each rewrite fills the same slots the weak line left blank: a length, a format, a named motion, and a mood. That is the whole move. You are not learning syntax, you are just answering the questions Pexo would otherwise have to guess at. If phrasing your idea is the part you find hardest, our guide to vibe creating prompts has more patterns you can reuse.
How to Generate the Video, Step by Step
With a description ready, the build itself is four short steps, all inside one chat.
Step 1: Open Pexo and Paste Your Description
Open Pexo and type or paste the description you wrote above. You do not have to know which model fits the job. Pexo reads your intent, fills any gaps, and routes the work to the right model behind the scenes. If you want to start with words only and add an image later, that works too, and our text to video walkthrough covers that path.
Step 2: Add Your Image or Generate One First
If you have a reference image, attach it to the same message and say what to do with it: "Animate this mug photo with a slow push-in and a soft light sweep." Pexo uses the still as the anchor for the scene, so the clip stays true to your product.
No image on hand? Ask Pexo to make one first, then animate it in the next line of the chat. Our image to video tutorial walks through that handoff in detail. Either way, the image and the description travel together, so Pexo knows both what the scene looks like and how it should move.
Step 3: Review Pexo's Plan and Preview
Before it builds the full video, Pexo shows its plan: a short outline of the shots it intends, plus a quick draft of the clip. Read that draft against your description. Does the motion match the mood you asked for? Is the subject framed the way you pictured it? This is your checkpoint, and nothing is locked yet. If something is off, you do not restart. You say what to change, and Pexo adjusts before committing to the finished render.
Step 4: Refine and Ship
Point at what you want different and describe the change in plain words: "make the zoom slower," "swap the music for something more upbeat," or "hold on the logo a beat longer." Pexo applies your notes and returns an updated version, and you can loop this as many times as you need. When the clip matches your idea, Pexo delivers a complete video with transitions, pacing, and sound handled. Download it and post it. No timeline, no export dance, no separate editor.
Common Mistakes to Avoid
A first result rarely misses because of the model. It usually misses for one of these reasons:
- A description that is too vague. "A short video for my store" has no subject, length, format, or mood, so the result is a guess. Run the line back through the six-slot formula above before you send it.
- The wrong aspect ratio for the platform. A wide 16:9 clip looks cramped as an Instagram Reel. Name the format up front (vertical, square, or wide) so the framing is right the first time.
- Baking hard text into the generation. AI video models still handle small on-screen text unreliably, so a headline or price rendered inside the clip can come out garbled. Keep the words out of the generation and add captions or titles afterward.
- A low-resolution source image. A blurry or tiny photo limits how much detail the motion can hold. Start from the sharpest version you have, or generate a clean still in Pexo first.
Pro Tips for Better Results
Once the basic flow feels natural, these habits raise the quality of what you ship:
- Describe the motion, not just the scene. "Slow push-in," "drift left," or "quick cuts on the beat" give Pexo direction a static description cannot. For a deeper breakdown of how to phrase camera and subject movement, our Seedance 2.0 prompt guide has more examples.
- Iterate in small steps. Change one thing per round. A single adjustment is easier to judge than five at once.
- Let Pexo route the model. Pexo works with the latest models, including Seedance 2.0, Kling AI, and more, and matches each job to the one that fits, which is a large part of what makes a conversational ai video agent faster than assembling a video by hand.
- Lock the format before you refine. Set the length and aspect ratio early so your refinement rounds go toward look and feel, not reframing.
What Else Can You Use
Pexo generates a video from scratch, and that is worth being honest about its edges. If you already have footage you want to trim, re-cut, or caption, Pexo is not the fit. It builds new video from a description and an image, it does not edit clips you already shot, so a timeline editor suits that job better. For everything up to and around the generation step, a couple of neutral tools help:
- Unsplash: a free library of high-resolution stock photos. Useful when you need a clean reference image and do not have your own.
- Canva: a template-based design platform. Suited to people who want to drag preset layouts and drop in assets rather than describe a scene in words.
Conclusion
Generating an AI video from an image and a description is mostly about the description. Fill the six slots (length, format, subject, motion, mood, and audio), add an image when you have one, and let Pexo handle the plan, the model, and the render. The clearer your line, the closer your first result. When you are ready, open Pexo and describe your first video.
