# Make a 30 to 60 second AI video from one prompt

> In the Percify chat, describe a video and pick 30s or 1min. Percify makes it in 10 second parts and joins them, for 2 credits a second.

Most AI video models stop at 10 or 15 seconds. In the Percify chat you can ask for a 30 second or 1 minute video from one prompt: Percify generates it in 10 second parts, starts each part on the last frame of the one before, and joins them into one video. It costs 2 credits a second: 60 credits for 30 seconds and 120 for a minute.

## What you need

* A computer. Long videos are made in the chat on the Home page of the desktop web app at [app.percify.io/home](https://app.percify.io/home).
* A description of the video. Optionally a photo for the first frame.
* Enough credits for the whole video before it starts: 60 for 30 seconds, 120 for 1 minute.

## How to make a long video

<Steps>
  <Step title="Describe the video">
    Click **Home** in the sidebar. In the prompt box, set the mode to **Video** and describe what you want. To start from your own image, click the **+** button (Upload image) and pick a photo. Click **Generate**.
  </Step>

  <Step title="Answer the chat's questions">
    The chat asks a few quick questions, such as the vibe, camera movement and light. When it asks **How long should it run?**, pick **30s** or **1min**. When it asks **What shape?**, pick 16:9, 9:16 or 1:1.
  </Step>

  <Step title="Confirm and go">
    The plan card, **Ready to create**, shows your prompt, your answers, the model that will run and the cost. Click **Go**.
  </Step>

  <Step title="Watch it build">
    The chat shows progress such as "Making part 2 of 3..." and then "Joining 3 parts into one video...". A 1 minute video is six parts, so expect it to take several minutes. Keep the page open until the video appears in the chat.
  </Step>
</Steps>

## How much does it cost?

| Length     | Parts | Credits |
| ---------- | ----- | ------- |
| 30 seconds | 3     | 60      |
| 1 minute   | 6     | 120     |

Each 10 second part is charged (20 credits) as it is made, but your balance must cover the whole video before the first part starts. If you are short, you see a message such as "A 30s video costs 60 credits and you have 40." If a part fails, that part is refunded; parts that were already made stay charged and the video is not finished. See [how credits work](/percify/credits) and [refunds](/billing/refunds).

## Limits

| Limit               | Value                                                                                      |
| ------------------- | ------------------------------------------------------------------------------------------ |
| Lengths in the chat | 5s, 10s, 30s or 1min (30s and 1min are built from parts)                                   |
| Shapes              | 16:9, 9:16 or 1:1                                                                          |
| Model               | Lengths over 10 seconds always use the 2 credits a second model, whatever model you picked |
| Where               | Desktop chat. The mobile chat offers 5s and 10s only.                                      |

## Tips

* Describe one continuous scene. Each part continues from the last frame of the previous part, so a story that jumps between unrelated places will not cut cleanly.
* Add a photo if the subject has to stay the same person or product from start to finish.
* Try the idea at 10s first with the default model. It is one part, costs 20 credits, and shows you how the scene moves before you pay for a minute.

<AccordionGroup>
  <Accordion title="Can I make 3 minute or 10 minute videos?">
    Not today. The chat offers up to 1 minute.
  </Accordion>

  <Accordion title="Why does the model change when I pick 30s or 1min?">
    Longer videos are built only from the model that renders exact 10 second parts, so the plan card shows that model and its price for any length over 10 seconds.
