Why streaming videos are different from regular files
When you watch a streaming video online, your browser doesn't download a single file. Instead, the video is broken into hundreds of small segments (typically 2-10 seconds each) that are downloaded and played in sequence. This is called adaptive bitrate streaming.
The two most common streaming protocols are:
- HLS (HTTP Live Streaming) — Apple's protocol, uses .m3u8 playlist files. Used by most websites, social media platforms, and streaming services.
- DASH (Dynamic Adaptive Streaming over HTTP) — Google's protocol, uses .mpd manifest files. Used by YouTube, Netflix, and many others.
Both protocols make it impossible to simply right-click and "Save As" — because there's no single file to save. A proper video downloader needs to parse the manifest, download all segments, and stitch them back together into a complete video file.
How to Download Streaming Video on Mac — Step by Step
Download Star Video Downloader
Get the free app from starvideoapp.com. Unzip and move to Applications. Works on macOS 14+ with Apple Silicon and Intel Macs.
Copy the page URL
Go to the webpage with the streaming video and copy the URL from your browser's address bar. You don't need to find the .m3u8 or .mpd file — the app does that automatically.
Paste and download
Paste the URL into Star Video Downloader and click Download. The app identifies the streaming protocol, resolves the manifest, downloads all segments, and assembles them into a single video file.
Watch offline
Your video is saved as a standard MP4, MKV, or WebM file — playable in any video player without an internet connection. Convert to a different format using the Convert tab if needed.
Tip: Star Video Downloader supports 1,000+ websites. If it can't automatically detect the video from the page URL, try copying the direct video URL (right-click the video player → "Copy video address" in some browsers).
Supported streaming sites
Star Video Downloader supports streaming content from a wide range of platforms:
- Video platforms: YouTube, Vimeo, Dailymotion, Twitch, Bilibili
- Social media: Twitter/X, Facebook, Instagram, TikTok, Reddit
- News & media: CNN, BBC, ABC, NBC, and many news outlet video players

What about DRM-protected streaming?
DRM (Digital Rights Management) is encryption used by paid streaming services to prevent downloading. Star Video Downloader does not bypass DRM and cannot download from:
- Netflix, Disney+, Amazon Prime Video, Hulu
- HBO Max, Apple TV+, Paramount+
- Any service using Widevine, FairPlay, or PlayReady encryption
The app works with freely accessible streaming content — videos you can watch without a paid subscription on the 1,000+ sites it supports.
Why a desktop app beats browser extensions
Browser extensions for downloading streaming video have several limitations:
- Quality caps: Browser APIs limit what extensions can capture, often maxing at 720p
- Frequent breakage: Sites update their players regularly, breaking extensions
- No merging: Extensions often can't merge separate video and audio streams
- Privacy risk: Extensions can access all your browsing data
- Chrome restrictions: Google has been restricting video download extensions in the Chrome Web Store
Star Video Downloader runs independently of your browser. It uses yt-dlp's constantly-updated site extraction library, supports full quality, and merges streams automatically with ffmpeg.
Frequently Asked Questions
Can I download any streaming video?
Star Video Downloader supports 1,000+ streaming sites including YouTube, Vimeo, Twitch, Dailymotion, Facebook, Twitter/X, and many more. DRM-protected streams from services like Netflix, Disney+, and Amazon Prime are not supported as they use encryption.
What streaming formats does it support?
Star Video Downloader handles HLS (m3u8), DASH (mpd), and progressive download formats. These cover the vast majority of streaming video on the web.
Why can't I right-click and save streaming videos?
Modern streaming video uses adaptive bitrate protocols (HLS or DASH) that split the video into hundreds of small segments. Right-clicking only gives you a single segment, not the complete video. A proper downloader reassembles all segments into a single playable file.
Can I download DRM-protected streams (Netflix, Disney+)?
No. DRM-protected content from services like Netflix, Disney+, Amazon Prime, and Hulu uses Widevine or FairPlay encryption. Star Video Downloader does not bypass DRM. It works with freely accessible streaming content from 1,000+ supported sites.
