After you have generated all the thumbnails, you can add the thumbnail as per your choice. We created a detailed post on how you can generate thumbnails from a video. I have also attached all the source files below, make sure you download them and let us know if you face any issue. All other attributes of video (bitrate, resolution, buffer size etc) will remain same. The newly created video file will have the thumbnail of your selected image file. When you hit the submit button, you will see a new file will be created at the root of your project’s folder named “output.mp4”. Select the video of your choice and select image from other field. Now you can run the script and you will see a form with 2 input fields, one for video and one for image. We are creating a form that will allow you to select video whose thumbnail needs to be changed and image which will be used as new thumbnail. You can download it from it’s official site. In order to change that thumbnail, you must have FFmpeg installed in your system. Which means the image you see on video thumbnail must have appeared somewhere in the video. The thumbnail assign by OS comes from one of the frames inside the video. Thumbnail of those videos are automatically generated by operating system itself. When it comes to operating system, you have a lot of video files in your hard drive and you can see little images that gives the insight of each video.

Most people use custom images as thumbnail and most are automatically generated by YouTube. It gives the preview of video and tells what the video is about. When you open YouTube, every video you must have see an image along with it’s title. Every operating system by default add a thumbnail to a video by itself. Thumbnail is basically a preview of video.
