The Technical Challenge of Reddit Video Downloads
Reddit hosts videos using a native CDN infrastructure known as v.redd.it. Unlike most websites, Reddit deliberately splits videos into two independent tracks: one track containing only the video with no sound, and a separate track containing the audio.
When regular web users save a Reddit video directly, they end up with a silent clip. AllMediaSave solves this by querying the Reddit manifest, fetching both stream fragments simultaneously, and multiplexing them via FFmpeg into a unified H.264/AAC MP4 file with synchronized audio.

Why Reddit Videos Download Without Sound on Regular Browsers
If you have ever right-clicked a Reddit video and saved it, you likely noticed the resulting file had zero audio. Reddit uses dynamic adaptive streaming (DASH) hosted under the `v.redd.it` domain. Under this architecture, the video track (such as DASH_1080.mp4 or DASH_720.mp4) and audio track (DASH_audio.mp4) are separate files transmitted simultaneously by the browser video player but stored independently.
AllMediaSave automates the entire multiplexing process: it queries the post JSON data, locates the matching audio track, and uses FFmpeg to mux them into a single H.264/AAC MP4 file.
How to Download Reddit Videos on Mobile and Desktop
On mobile devices using the Reddit app, tap the "Share" icon on any video post and choose "Copy link". Open Safari or Chrome, visit this page, paste the URL into the input field, and tap "Analyze". Once resolved, tap "Download MP4" to save the complete video with synchronized sound.
On desktop, copy the URL directly from your browser address bar (supports both `new.reddit.com`, `reddit.com`, and `old.reddit.com`). Paste it into the search box and click "Analyze" to receive your merged MP4 file.
Working with Reddit New Mobile Share Links (/s/...)
Reddit recently introduced new short share links with the structure `reddit.com/r/subreddit/s/xxxxxx`. These shortened links redirect to the full discussion thread. Our backend unrolls these shortlinks automatically and extracts the direct media manifest.
Silent Animated GIFs vs Real Video Posts
Some clips on Reddit are originally posted as silent animated GIFs (either uploaded as `.gif` files or converted by Reddit into video loops without an audio channel). In those cases, AllMediaSave delivers the full-resolution video file without artificial audio insertion.
