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 single high-definition H.264/AAC MP4 file.
