## Tutorial contents
This tutorial presents the following topics. Click a timestamp to jump to that part of the video.### Introduction
{table:class=tutorial-bullets}|  | 
| --- | --- |
|{videotime:id=media :min=0 :sec=00 :player=cld} | If you want to remove the start or end of a video, you can use Cloudinary's [video transformation capabilities](video_trimming_and_concatenating#trimming_videos) to do this on the fly.
|

### Define the length of your video
{table:class=tutorial-bullets}|  | 
| --- | --- |
|{videotime:id=media :min=0 :sec=23 :player=cld} | Having [installed and configured the Cloudinary Node.js SDK](node_configuration_tutorial) in your Node.js app, define the start offset and either the end offset or duration of the video that you want to deliver. Ensure you use the variable names `start_offset`, `end_offset` and `duration` as these are the object key names that you need in the next step, which uses object property shorthand notation.
|

### Create the URL to trim the video
{table:class=tutorial-bullets}|  | 
| --- | --- |
|{videotime:id=media :min=0 :sec=38 :player=cld} | Use the `cloudinary.url` method to create the URL to deliver the trimmed video according to the set parameters. Specify the public ID of the video that you've previously [uploaded](upload_images) to your Cloudinary product environment, the resource type and transformation parameters.  For example, to trim the `samples/elephants` video to make it start at 6.5 seconds and end at 20 seconds:
|

```nodejs
const start_offset = 6.5;
const end_offset = 20;

const videoUrl = cloudinary.url('samples/elephants.mp4', {
  resource_type: 'video',
  transformation: [
    {
      start_offset, 
      end_offset,
    },
  ],
});
```

See the full code example in [GitHub](https://github.com/cloudinary-community/cloudinary-examples/blob/main/examples/node-transformations-effects/video-trim.js).

### Check the resulting URL
{table:class=tutorial-bullets}|  | 
| --- | --- |
|{videotime:id=media :min=1 :sec=27 :player=cld} | Open the resulting URL in a browser to see the trimmed elephants video.
