Introduction
| Jump to this spot in the video 0:00 | The CldVideoPlayer component of the Next Cloudinary library allows you to embed videos for optimized delivery, maximizing performance in Next.js. |
Deliver a video using an HTML video tag for comparison
| Jump to this spot in the video 0:16 | Using an HTML video tag to embed a video on a webpage delivers the whole video in its original size and format. |
Deliver the video using the Cloudinary CldVideoPlayer component
| Jump to this spot in the video 0:46 | Delivering the same video using the CldVideoPlayer component of the Next Cloudinary library, optimizes the format and quality for delivery, so a much smaller file is delivered. |
Crop and resize the video
| Jump to this spot in the video 2:11 | In addition to optimizing the format and quality of your videos, you can resize them on the server side so that you deliver only the size you need. Specify an object in the transformation prop including the type of crop, its focus (gravity), plus the width and height. |
See examples of using the CldVideoPlayer component in GitHub.
