# Video Preview [](https://www.npmjs.org/package/video-previews)
Make sprite sheets or gif previews of your videos using Node.js
The module creates two types of previews:
- Horizontal or vertical sprite sheet for css `animation-timing-function: steps(10, end)`
- Animated gif image
## API
```javascript
await VideoPreview(input_file, output_file, total_frames[, options])
```
### input_file
**Type**: _String_
Full path to source video file.
### output_file
**Type**: _String_
Full path to preview file. Pay special attention to the file extension, it is here that the type of preview to be made is determined!
### total_frames
**Type**: _Number_

### options.temp_dir
**Type**: _String_
**Default**: `{INPUT FILE PATH}/temp_{UNIQ ID}/`
Temporary folder for storing video frames
### options.video_length
**Type**: _Number_

For now it works only for gif output format
### options.direction
**Type**: _String_
**Default**: `v`
Frames direction for `jpg` or `png` sprite sheets
| Key | Value |
| ------ | ------ |
| v | vertical direction |
| h | horizontal direction |
### options.fps
**Type**: _Number_
**Default**: `1`
Gif frame rate
### options.loop
**Type**: _Boolean_
**Default**: `true`

### options.ffmpeg_bin
**Type**: _String_

### options.cleanup
**Type**: _Boolean_
**Default**: `false`

### options.silent
**Type**: _Boolean_
**Default**: `true`
Enables logging `stdout` / `stderr` data
### @output
**Type**: _Object_
```javascript
{
file: 'z:/preview.gif'
}
```

const VideoPreview = require('video-preview');
let frames = 10;
let input_file = './videos/MONICA BELLUCCI in the Matrix Sequels (HD Movie Scenes).mp4';
let output_file = './videos/preview.gif';
VideoPreview(input_file, output_file, frames, {
width: 320,
