FAQ
Can I Download Videos with Subtitles or Multiple Audio Tracks?
Video Downloader Pro can detect and download subtitle tracks and multiple audio language options when they are present in HLS or DASH streams. Whether these options appear depends entirely on how the website serves the video — the extension surfaces what the source makes available. Here is a full breakdown of how multi-track detection works, what you can do with it, and where the limitations are.

How HLS and DASH Multi-Track Streams Work
Modern streaming protocols — HLS (HTTP Live Streaming) and DASH (Dynamic Adaptive Streaming over HTTP) — are designed to support multiple audio tracks and subtitle streams alongside the main video. A single HLS playlist file can reference several audio renditions (for example, English, Spanish, and French audio), as well as subtitle tracks in various languages. Video Downloader Pro reads these playlist manifests and presents the available options when you open the extension popup.
- Audio renditions — Different language audio tracks are listed as separate downloadable options, each tagged with the language code (e.g., en, es, fr) when the website provides this metadata.
- Subtitle tracks (WebVTT, SRT) — Some HLS streams include subtitle tracks as WebVTT files referenced in the playlist. The extension can detect these and offer them as a separate download alongside the video.
- Video quality levels — Multiple resolution levels (1080p, 720p, 480p) are also part of the adaptive stream. You select the quality independently from the audio track.
Selecting an Audio Language Track
When a video has multiple audio tracks available, Video Downloader Pro displays them in the download options for that stream. The process depends on how the site packages the stream.
- Combined audio+video — On many platforms, each quality level already has audio baked in. If the site serves separate language tracks, you will see them listed as distinct download options, each named by language or track label.
- DASH separate streams — DASH often delivers audio and video as completely separate files. The extension will show the video stream and audio stream(s) independently. You download both and use a tool like VLC or ffmpeg to combine them if needed.
- Default track selection — If only one audio track is available (the default), the extension downloads it automatically as part of the merged file. No extra steps are needed.
Downloading Subtitle Files
Subtitles in HLS streams are typically served as WebVTT (.vtt) files. When the extension detects subtitle tracks in the playlist manifest, they appear as separate downloadable items alongside the video.
- WebVTT format — The standard subtitle format for HLS streams. VLC, most media players, and video editors can load .vtt files alongside the video.
- SRT conversion — Some platforms serve subtitles that can be converted from WebVTT to SRT format using free tools if your media player requires SRT.
- Burned-in subtitles — If subtitles are hardcoded into the video itself (not delivered as a separate track), they will always be part of the downloaded video file and cannot be turned off.
- No subtitle track detected — Many videos simply do not include external subtitle tracks. If the source does not serve a subtitle file, the extension cannot create one. In this case, no subtitle option will appear in the download list.
When Multi-Track Options Are and Are Not Available
Not all video sites serve multi-track streams. The availability of audio language options and subtitles depends entirely on the source platform.
- Available — Professional video platforms, educational sites with translated content, international media outlets, and streaming-style sites often include multiple audio/subtitle tracks in their HLS manifests.
- Not available — User-uploaded videos, simple MP4 embeds, and most social media clips are single-track. What you see is what you get.
- DRM-gated tracks — Some platforms attach DRM to their alternate audio tracks even if the primary video is accessible. In these cases, the extension may detect the track references but not be able to download the content.
- YouTube — YouTube has its own subtitle system (auto-generated and community captions) that is not accessible through the extension due to platform restrictions. This applies to audio tracks as well.
Limitations to Be Aware Of
While Video Downloader Pro can handle multi-track streams when the source exposes them, there are practical limits to what is possible.
- No automatic muxing — When audio and video are separate DASH streams, the extension downloads them as individual files. Combining them into a single video file requires an external tool such as VLC (Media > Convert/Save) or ffmpeg.
- Language metadata — Not all platforms label their audio tracks with readable language names. Some use language codes (en-US, es-419) that may not be immediately obvious.
- Subtitle timing — Downloaded WebVTT files rely on timing data from the source. If the source has errors in subtitle timing, the downloaded file will reflect those same errors.
- Free tier — The free tier limits video quality to SD (480p), but subtitle files and audio-only tracks are not subject to this cap. For high-quality video downloads with multiple tracks, see our 4K quality guide.
