How to Save a Reddit Video With Sound

Reddit hosts video using DASH, a streaming format that deliberately splits a video into pieces. Instead of one self-contained file, Reddit stores several video-only renditions at different resolutions, one audio-only file, and a small manifest describing how they fit together.

The player reads that manifest, picks a video rendition suited to your connection, and plays it in sync with the audio file. This is efficient for streaming — the player can switch resolution mid-playback without interrupting the sound — but it means no complete video file exists on Reddit's servers at all.

So when you right-click and save, or point a generic downloader at a v.redd.it link, you retrieve exactly one thing: a video-only rendition. It plays perfectly and it is completely silent, because the audio was never part of that file.

Putting the two streams back together is called muxing. It is worth understanding that this is not the same as re-encoding.

Re-encoding decodes both streams and compresses them again, which takes time and loses quality. Muxing simply writes the existing compressed streams into a single MP4 container, untouched. The result is mathematically identical to the source — the same picture, the same audio, now in one file — and it completes in about the time it takes to move the bytes.

Use our Reddit video downloader with sound. Paste the post URL and choose any option marked "with audio" — the merge has already been done, so you receive a finished MP4.

Use the full post link rather than a bare v.redd.it URL. A bare v.redd.it link sometimes lacks the reference needed to locate the matching audio track, which is one of the more common reasons a download comes back silent even from a tool that supports merging.

1. Open the post on Reddit and tap Share, then Copy link.

2. Open the Reddit video downloader and paste the link.

3. Choose an MP4 labelled "with audio" at your preferred resolution.

4. Play the file once before deleting the original post link, just to confirm the audio is there.

5. On iPhone it saves to Files → Downloads; tap Share then Save Video for Photos. On Android it goes to your Download folder.

Not every silent Reddit video is a failed download. Plenty of clips are uploaded with no audio track at all — screen recordings, silent animations, and content crossposted from platforms that stripped the audio.

If the format list shows no audio option for a post, Reddit genuinely has none to give. That is worth checking before assuming the tool failed.

A quick way to tell the difference: play the video on Reddit itself with your volume up. If it is silent there too, there is no audio to recover. If it plays with sound on Reddit but downloads silent, that is the DASH problem described above.

The merge is not magic and you can do it yourself. Reddit exposes a JSON version of any post by appending .json to the URL, which lists the DASH playlist location. From there the video and audio files sit at predictable addresses under the same v.redd.it identifier.

Once you have both files, ffmpeg joins them with a stream copy — no re-encoding, so it finishes almost instantly and loses nothing. The command is a single line and the output is an ordinary MP4.

This is genuinely worth knowing if you download from Reddit often, or if you want to understand what any tool is actually doing on your behalf. The trade-off is that you are doing four steps by hand for something a tool does in one, and Reddit occasionally changes the manifest layout in ways that break hand-rolled approaches.

Handling DASH properly costs a downloader real money. Merging means both streams have to pass through the tool's own server, which consumes bandwidth the operator pays for. Handing over a video-only URL and letting your browser fetch it directly from Reddit costs them nothing.

That is the whole reason silent Reddit downloads are so common. It is not usually a bug — it is the cheaper implementation, and most sites in this space do not mention which one they use.
