This article will show you how to download M3U8 video streams to MP4 for later use.
M3U8 is a popular format used for online video streaming, primarily for HLS (HTTP Live Streaming) protocol. Such stream is a media split into multiple small files/segments, which enables adaptive streaming based on the viewer's internet condition or device compatibility. M3U8 is a text-based small file that doesn't actually contain media data like MP4, it contains URL references to the segmented media playlist. With the .m3u8 URL, you can download M3U8 videos to MP4 format using a desktop/online downloader or browser extensions.
Note: Some M3U8 videos are encrypted, use a professional downloader software to decrypt and download them without a hassle.
To download M3U8 to MP4, we need to obtain the M3U8 URL from the video webpage or an M3U8 file.
If there are multiple links, the first M3U8 link usually gives more information and works best when pasted into downloaders. The last M3U8 link is related to the current video stream of a specific resolution, and sometimes online tools can only detect the last one. I often use the first URL, which will show me the video cover, file size and all resolution options.
An M3U8 file is a plain text file, so you can open it with any text editor like Notepad. Find the URL that ends with the .m3u8 file extension, copy and paste it into any M3U8 downloader. If there is more than one URL, choose based on the video resolution you prefer.
A dedicated M3U8 video downloader allows users to choose video resolution and download faster.
