HLS and DASH stream downloads
Adaptive streams are segmented — the video is split into dozens or hundreds of small chunks spread across separate files. Video Downloader Plus handles the entire download pipeline:- Parses the manifest file to map out every video and audio segment
- Fetches multiple segments at the same time for faster overall download speed
- Reassembles them into a single, contiguous media file
- Optionally remuxes the result into your chosen container format
- Parallel segment fetching — Concurrent connections mean faster downloads, especially for longer videos
- Retry on interruption — If a download stalls, you can restart it without losing progress
- Automatic audio merging — When a stream carries audio and video in separate tracks, Video Downloader Plus combines them into one file automatically
- Full quality selection — Every variant declared in the manifest is available to choose from
- Live stream recording — Capture ongoing live broadcasts (Professional plan)

Download settings
You can adjust download behavior from the options page:- Download management — Activates the browser’s download management API, giving you more control over save location and file naming. This requires a separate optional browser permission, requested at runtime.
- Download path — Set a folder prefix so Video Downloader Plus organizes files into a subdirectory (e.g.,
Video Downloader Plus/inside your Downloads folder). - File naming — Filenames are generated from the video title and deduplicated automatically by appending a number if a file with the same name already exists.
