The **Still to Video** node turns one still image and one audio track into an MP4 video. The video is exactly as long as the audio, and an optional motion effect, such as a zoom, a pan or a Ken Burns move, brings the still to life. No AI model runs, so the node always costs 0 credits.

- Found in: Video › Create
- Output: video
- API type: `still-to-video`

## When to use it
- A narrated slide: a generated image with a voiceover becomes a ready video segment.
- A podcast or music visualizer: cover art with the track becomes an MP4 you can upload.
- A photo moment inside a longer edit: send the result to [Combine Videos](https://nodaro.ai/docs/nodes/video/combine-videos).
- Any [Generate Image](https://nodaro.ai/docs/nodes/image/generate-image) result as video, without spending credits on a video model.

For several images over one track, use [Slideshow](https://nodaro.ai/docs/nodes/video/slideshow).

## Quick start
### Add the node

Press Tab on the canvas and choose **Video › Create › Still to Video**.

### Connect the image and the audio

Connect an image node to **Still image** and an audio node to **Audio**, for example [Text to Speech](https://nodaro.ai/docs/nodes/audio/text-to-speech) or an uploaded track.

### Choose the motion and the frame

In the settings panel, choose a **Motion** and an **Intensity**, then the **Resolution**, **Aspect Ratio** and **Fit**.

### Run it

Click **Run**. The MP4 appears on the node.

Workflow: A generated image and a voiceover become a narrated video segment, ready to join with other clips.

- Generate Image → Still to Video (still image)
- Text to Speech → Still to Video (audio)
- Still to Video → Combine Videos

## Inputs
| Input | Accepts | What it does |
| --- | --- | --- |
| **Still image** | Image nodes | The picture to show. Required. |
| **Audio** | Audio nodes, such as Text to Speech, Generate Music, Upload Audio or Extract Audio | The soundtrack. Required. Its length sets the length of the video. |

The output, **Video**, is an MP4 file with H.264 video and AAC audio.

## Settings
| Setting | What it does |
| --- | --- |
| **Motion** | **None** (the default), **Zoom in**, **Zoom out**, **Pan left**, **Pan right** or **Ken Burns**. With None, the render is a fast static frame. |
| **Intensity** | How strong the motion is, from 1 (subtle) to 10 (strong). The default is 3. It has no effect when Motion is None. |
| **Resolution** | **720p**, **1080p** (the default) or **4K**. The value names the short edge of the frame; the long edge follows the aspect ratio. |
| **Aspect Ratio** | **16:9** (the default), **9:16**, **1:1** or **4:3**. |
| **FPS** | **24** or **30** (the default) frames per second. |
| **Fit** | **cover** (the default) crops the still to fill the frame. **contain** shows the whole still and fills the bars with the pad color. |
| **Pad Color** | The color of the bars when Fit is contain. The default is black, #000000. |

There is no duration setting. The length of the video always equals the length of the audio, read when the render starts.

## Credits
Still to Video always costs 0 credits. It renders on Nodaro's own media engine, with no AI model.

## Tips
- **Feed a large enough image.** The node never adds detail to your image; it only frames it. Use a still at or above the output resolution.
- **Choose the fit by content.** Use cover for full-bleed footage, and contain when the whole image must stay visible, such as posters, artwork and documents.
- **Match the motion to the mood.** Ken Burns at an intensity of 2 to 4 reads as documentary; 7 and above reads as deliberate motion graphics.
- **Expect static bars.** With contain and a motion, the still moves inside the frame and the bars stay still.
- **4K with motion is the slow path.** Without motion, even 4K renders quickly.

## Frequently asked questions

### How long is the video that Still to Video makes?

Exactly as long as the connected audio. The node has no duration setting. If the audio's length cannot be read, the render fails with a clear error instead of making an empty file.

### Does Still to Video cost credits?

No. It renders the video with Nodaro's own media engine and runs no AI model, so it always costs 0 credits.

### What is the difference between cover and contain?

Cover crops the image to fill the whole frame. Contain shows the whole image and fills the empty bars with the Pad Color, which suits posters, artwork and documents.

### Can I animate more than one image?

Not with this node. For 2 to 100 images over one audio track, use the Slideshow node.
