How do I download video from blob link on Windows 11 ?

Copper Contributor

I'm currently facing an issue with downloading a video from a website that uses a blob URL. I noticed that the video content I'm trying to download is embedded in the webpage and is accessed via a blob link, which typically starts with 'blob:'. Unlike conventional links, I'm unable to directly save the video by right-clicking on it. I've tried several methods such as looking through the page source and inspecting elements using developer tools, but I still can't figure out how to retrieve the actual video file from the blob URL. Could anyone provide guidance or recommend tools that could help with downloading a video file from a blob link?

There are some online video downloader you can try if you want to download video from blob link on Windows 11 computer, like SaveFrom.net, ClipConverter, or Online Video Converter. Just copy the blob link and paste it into the online downloader, and then select the desired video format and resolution. Click "Download" to start download video from blob link on Windows 11.

Online video downloaders can be accessed from any device with an internet connection, including Windows, macOS, and mobile devices. They often have a simple and user-friendly interface, making it easy to copy and paste the blob link, You don't need to have technical knowledge or coding skills to use them.

A blob video is a type of video that uses a combination of animation and visual effects to create a mesmerizing, abstract, and often hypnotic visual experience. The term "blob" refers to the use of irregularly shaped, amorphous shapes or "blobs" that move and morph on the screen, often in response to music or sound.

 

You have to use a dedicated app to download video from blob link. There are many choices from the Internet and you can try them out one by one.

To download video from blob link, first navigate to the network tab of Chrome or Edge developer tools. You can always find it, as this is the standard method. Look for the file with m3u8 extension. Alternatively, you can use the youtube-dl tool to automatically detect the m3u8 file when given a direct link to the webpage.

 

Next, copy the link of m3u8 file to youtube-dl command-line tool (download). It can download content from various sources beyond just YouTube. It will automatically download each segment and combine them using FFmpeg, then discard unnecessary parts. The tool may support the site you're interested in downloading from without requiring step #1.

 

If you encounter a stubborn site that generates 403 errors, try using Telerik Fiddler. This tool acts as a local proxy, capturing and saving any transmitted data, including video files. With Fiddler, you can download almost anything, except for DRM-protected content like Spotify.

I'm not into using plugins, but you might want to check out this website.

It seems you can even download TikTok videos with it (though I haven't tried that myself). I used it with a blob link and was able to download blob video in various qualities with just a few clicks.

The term 'blob' indicates that the video data is stored as an Array Buffer in memory. You can upload the blob to AWS S3 and download it from there. In my experience, dealing with m3u8 files can be quite challenging. So, I personally recommend you using some software to download blob url videos , google it.

It's hard to directly download blob link video because it is stored directly in memory as an Array Buffer. Although there are methods to extract this data, the optimal approach is to access the source before it's converted into a blob.

 

The M3U8 format is used for video-on-demand services and works differently from standard video files, which are typically downloaded in one piece. Instead, M3U8 videos are divided into smaller, manageable chunks, detailed in the M3U8 playlist. To download blob videos, you'll need to find and download all the segment files, usually in .ts format, and then merge them into a complete video.

 

Stop using download video from blob link on Windows 11. Online video downloaders may pose security risks, as you're providing sensitive information such as the video URL to a third-party website or service.

Since a blob is already a sign that content has been downloaded, there's no need to re-download it. Unlike text data, blobs are binary data, which means they take up significantly less space. Additionally, since the data has already been downloaded, the browser doesn't need to send multiple requests to the originating server to render the content. This reduces the number of requests and improves overall performance.

 

You can use this JS code to download video from blog link url:

 

 

function onChange() {
  var file = document.getElementById('fileItem').files[0];
  var vid = document.getElementsByTagName('video')[0];
  var url = URL.createObjectURL(file);

  document.getElementById('blob').innerHTML = "Blob URL is:<br>".concat(url); 
  document.getElementById('fileItem').type = "hidden";

  vid.src=url;
  vid.load();
  vid.onloadeddata = function() {
    vid.play();
  }
}
