### Use other version of ffmpeg.wasm-core / @ffmpeg/core
For each version of ffmpeg.wasm, there is a default version of @ffmpeg/core (you can find it in **devDependencies** section of [package.json](https://github.com/ffmpegwasm/ffmpeg.wasm/blob/master/package.json)), but sometimes you may need to use newer version of @ffmpeg/core to use the latest/experimental features.
**Node**
Just install the specific version you need:
```bash
$ npm install @ffmpeg/core@latest
```
Or use your own version with customized path
```javascript
const ffmpeg = createFFmpeg({
corePath: '../../../src/ffmpeg-core.js',
});
```
**Browser**
```javascript
const ffmpeg = createFFmpeg({
corePath: 'https://unpkg.com/@ffmpeg/core@0.8.3/dist/ffmpeg-core.js',
});
```
