4 Ways to Download Blob Videos (Free and Automated)

💡 Quick Summary: How to Download Blob Videos?

If you are staring at a src="blob:https://..." link and getting a 404 error or a corrupted file, you cannot download the raw blob URL directly. Instead, you need to extract the underlying streaming manifest.

• Best Overall (Automated & Batch): Use VideoProc Converter AI to parse .m3u8 or raw .ts streams in one click with original quality.
• Quick Online Method: Copy the stream URL and use an online m3u8-to-MP4 converter (e.g., KEEPVid).
• Free Open-Source Method: Stream and convert the blob link via VLC Media Player (requires manual configuration).

When you inspect the webpage of an online video, you may notice that the video elements come with a blob URL. However, if you try to directly download the video with that blob URL, you may encounter network errors, or fail to analyze the video. Here you will find 3 solutions to download blob video in full length and at the original quality.

If you have ever tried to retrieve the source video instead of using the blob URL in the DevTools, you may be overwhelmed by tons of URLs that are likely to be the correct link for the blob video. Often, the downloaded files end up corrupted, or you accidentally download only a partial segment by incorrectly targeting individual .ts files. The process can also be confusing when multiple video links appear in DevTools, leaving you unsure of which one to actually select. Sometimes, you may face issues with Blob URLs that simply won't open, returning a 404 error code or a "file not found" message.

What Are Blob Videos

Blob videos refer to videos that are handled using Binary Large Objects (BLOBs).

Binary objects such as images, videos, and more are encapsulated as a blob object. The Blob URL is a a temporary, local URL created to refer to the objects. That is, the link is a pointer to the raw video, not the video itself. To download the video, you need to find the true source of the file, instead of those in blob: http…

Follow the proven methods below to download a video with a blob in the URL. It works for Twitter blob video, Vimeo blob video, JW Player blob video, and many streaming blob storage videos.

Quick Comparison: Which Downloader Should You Choose

Prerequisite: Locate the File

You probably already know how to download embedded video on a webpage, with DevTools that inspect the script of the page, and find the URL of the corresponding video.

When you are trying to download video with blob URL, you will see src="blob: https://page-link". However, if you copy and paste that link into a video downloader, chances are that the downloader will fail to analyze the video source.

Here you will learn how to locate the source video file, and how to download it, both for live-streaming blob videos and for video-on-demand.

Step 1. On the page with a blob video that you want to download, right-click and hit Inspect to use the DevTools.

Step 2. Click the Network Tab, which stays between the Sources and Performance tabs.

Step 3. Play the video, and keep an eye on the information displayed under the Network tab.

What to do if nothing appears under the Network tab?

You can hit F5 to refresh the page, or press Ctrl+F5 to force refresh the page.

Always make sure the video is playing, not paused or stopped.

Step 4. You shall see an .m3u8 item under the Name column. Right-click on the .m3u8 and hover to Copy > Copy link address.

Tips:

1. If you cannot find a URL that contains the video, you can try to switch the viewing mode from Responsive to an Apple device or other mobile device, and refresh the page when needed.
2. Depending on the specific webpage, each platform may have its own way to host the video with blob URL. Besides the above-mentioned method, you can also check how to find the URL of Vimeo video with DevTools.
3. What if you find a .mpd file instead of .m3u8 (DASH Protocol)? While HLS (.m3u8) is dominant on many streaming platforms, you may occasionally encounter .mpd files under the Network tab when inspecting certain modern websites. MPD stands for Media Presentation Description, which is the manifest file format for MPEG-DASH streaming. Just like .m3u8, you cannot download a blob video directly by copying its raw blob link. You can right-click the .mpd link in DevTools, choose Copy link address, and get ready to handle .mpd streams seamlessly with the following approach.

Preparation Done!

Now that you have an m3u8 address, you can use the dedicated downloader - VideoProc Converter AI - to download the blob video. See below the detailed steps.

Bonus Tips:

1. Download blob video subtitles

If the blob video comes with subtitles, you can also find the subtitle URL and use VideoProc Converter AI to download the subtitle. For instance, under Network where you find the m3u8 address, you will also see .vtt file address, which is the subtitle file.

When you playback the video, change the subtitle file name to the same of the video name, and most players will automatically load the subtitle for the video.

2. How to download blob video without m3u8 (or when you cannot find m3u8 address)

For certain web pages, the m3u8 address is unavailable. Instead, you only see multiple .ts file address. They are spanned parts of the video, you can copy each of the addresses, paste it in VideoProc Converter AI, add them to the queue and download multiple .ts files to the local drive.

Since VideoProc Converter AI also has basic editing tools, you can merge spanned .ts files into one video quickly without transcoding.

How to Download Blob Video Online

Another way to download blob videos is to seek help from online tools. As we already locate the file with its m3u8 URL, you can use online tools to convert m3u8 to MP4 and save the files to the local disk. KEEPVid is one of the most capable blob downloader online. Let's see how it works:

Step 1. Visit https://www.keepvid.to/1-m3u8-converter

Step 2. Paste the blob video URL that we found at the beginning of this article (using the Dev tools).

Step 3. Click Go to start downloading the video.

Step 4. Choose available options offered by the tool. You can download the video, or audio only. Depending on the source video, you may be able to download the HLS video.

How to Download Blob Video via VLC

VLC is an open-source media player, with hidden features to stream online videos and download videos.

Although the batch downloading in VLC is awkward to set up, you still can use VLC to download blob videos with some learning curve. We will list detailed steps below in case you miss any steps.

Step 1. Install VLC from its official site: https://www.videolan.org/

Step 2. At the top right of its menu, click Media > Open Network Stream.

Once you copy and paste the blob video link and hit play, VLC will start to stream the video in its player. Since we want to download the blob video, instead of merely streaming it, the option is slightly different here.

Step 3. Click the little triangle instead of clicking on the Play button, and you will see a drop-down menu. Hit Convert.

Step 4. In the pop-up window, choose the desired format to download the blob video. You can choose Video MP4 (video stream encoded in H264 and audio in MP3).

Step 5. Click Browse to choose an output path, and hit Start to download blob videos.

Note: If the URL you located corresponds to a live-streaming blob video, VLC cannot save it to the local drive while working in the background. The Capture feature in VLC will record everything that goes on your screen. Instead, you can use

VideoProc Converter AI mentioned above to download the live-streaming video in the background.

How to Download Blob / HLS Videos via yt-dlp & FFmpeg

If you prefer a command-line approach and have technical experience, yt-dlp (an upgraded fork of youtube-dl) combined with FFmpeg is one of the most powerful and reliable open-source tools for developers and tech-savvy users.

It can automatically parse complex streaming manifests, including HLS (.m3u8) and DASH (.mpd) links, bypass certain edge-case restrictions, and merge audio/video tracks seamlessly into a high-quality MP4 file.

Here's how to use yt-dlp:

Step 1. Install Dependencies: Ensure you have Python installed, then install yt-dlp via your terminal (e.g., using pip install --upgrade yt-dlp). You also need to download FFmpeg and add it to your system's environment PATH so yt-dlp can handle muxing.

Step 2. Copy the Manifest URL: Use the browser's DevTools (Network tab) as shown in the prerequisite section to locate and copy the .m3u8 or .mpd link of the target video.

Step 3. Run the Command: Open your terminal or Command Prompt, and run the following command:

yt-dlp "YOUR_M3U8_OR_MPD_LINK_HERE"

Step 4. Output File: yt-dlp will automatically fetch all video segments, decrypt/download them, and use FFmpeg in the background to output a clean, playable .mp4 file to your working directory.

Note: While extremely powerful, yt-dlp lacks a graphical user interface (GUI), making it less intuitive for beginners who prefer batch-queue management, background live stream recording, or basic editing features in a single desktop suite.

FAQ: Solving Common Blob Video Download Failures

1. Why do I get a "403 Forbidden" or network timeout error when pasting the .m3u8 link into an external downloader?

Cause: Streaming servers frequently enforce strict security policies, such as checking request headers (Referer, Origin, and dynamic session cookies). If an external tool sends a naked request without matching browser headers, the server rejects it with a 403 error.

Solution: Use an automated desktop downloader like VideoProc Converter AI that captures and passes the necessary session headers and tokens along with the stream URL, or switch to a command-line tool like yt-dlp which allows you add custom headers if needed.

2. Why does the downloaded video have smooth playback but absolutely no sound?

Cause: Modern streaming providers (especially on platforms using advanced HLS or DASH) often separate the video stream and audio stream into two independent files to optimize bandwidth delivery.

Solution: Avoid simple video-only grabbers. Ensure your software or command-line script supports automated muxing—meaning it detects both manifests, downloads them in parallel, and merges them into a single MP4 container via FFmpeg.

3. What should I do if no .m3u8 or .mpd manifests appear under the Network tab when playing the video?

Cause: Some modern web applications use custom JavaScript encapsulation, proprietary chunk loaders, or encrypted WebSockets that conceal standard manifest URLs from the developer tools.

Solution: First, try hard-refreshing the page (Ctrl+F5 or Cmd+Shift+R) while keeping the Network tab open from the very beginning. If the stream remains hidden, standard URL-parsing methods won't work; instead, use VideoProc's built-in Screen Recorder mode to capture the content losslessly at 1:1 original quality.
