Reddit Video Downloads With No Sound? Here's the Real Reason (and the Fix)
You open a Reddit video, the sound plays fine on reddit.com, but the moment you download it — through a browser extension, a right-click on the video element, or a generic downloader — the saved file is completely silent. This isn't a broken download or a codec problem on your end. It's how Reddit stores the file in the first place.
Why this happens
Reddit hosts self-uploaded videos on its own CDN, v.redd.it, using MPEG-DASH — a streaming format built around a manifest file (Reddit serves this at a DASHPlaylist.mpd address for each video) that lists multiple separate media "representations" a player can choose between. For a Reddit video, that manifest points to at least two distinct files: a video-only track and an audio-only track. Reddit's own player fetches both and plays them in sync while you watch, which is why the video looks completely normal on reddit.com.
The problem shows up the moment you try to save the file yourself. If you grab the video track's direct URL — which is what a simple right-click, a basic browser extension, or a naive downloader usually ends up doing — you get exactly that: video only, no audio track attached. The sound isn't missing or corrupted; it was never part of that file. It's sitting in a second, separate file that has to be fetched and merged in.
This is a well-known enough quirk of Reddit's hosting that it shows up directly in how mainstream open-source downloading tools handle Reddit: yt-dlp's Reddit extractor works by fetching that same DASHPlaylist.mpd manifest and parsing out the separate audio and video representations it contains, rather than assuming a single downloadable file exists.

The fix
The fix is straightforward in principle: fetch both the video-only and audio-only files Reddit's manifest points to, then combine them into a single playable file. That's the whole job our Reddit downloader does — paste the post's link, and it merges both streams server-side before handing you one MP4 with sound included, so there's no separate step or extra tool required on your end.
One detail that trips people up: paste the Reddit post link (reddit.com/r/…/comments/…), not the bare v.redd.it address by itself. The post link is what reliably lets a tool locate every stream that belongs to that video, including the audio track — a bare v.redd.it link sometimes resolves to only the video file.
Why can't I just save the video directly?
This same fetch-what-the-player-fetches limitation applies to right-click saving on most video sites, not just Reddit's audio problem specifically — see Why You Can't Just Right-Click-Save a TikTok, Instagram, or Reddit Video for the broader mechanism.
Frequently asked questions
- Is this a bug in my browser or download tool?
- No — it's working as designed on Reddit's side. The video and audio genuinely are two separate files on Reddit's servers, so any tool that only fetches the video track will produce a silent file, regardless of the browser or app you're using.
- Does this affect every Reddit video?
- It affects Reddit-hosted videos served from v.redd.it, which is most native video posts. Content embedded from third-party hosts (Imgur, YouTube links shared as a post, etc.) is a different platform's file entirely and isn't affected by this specific issue.
- Can I fix an already-downloaded silent video myself?
- If you separately have both the video-only and audio-only files, a tool like ffmpeg can mux them into one file — but that requires already having found both correct file URLs, which is the actual hard part. Downloading the post link through a tool built to merge both streams (like ours) does that step automatically.
- Does the merged download work on private or quarantined subreddits?
- No. The post has to be publicly viewable without logging in. Private communities and opt-in quarantined subreddits require an authenticated Reddit session that a downloader doesn't have and shouldn't try to use.
