KepVideo Wiki

Features

What KepVideo can do: stream detection, quality and audio choice, MP4 assembly and more.

Finding the right video

  • Lists every detected HLS playlist and direct MP4/WebM file on the current tab — nothing is hidden.
  • Marks the stream whose duration matches the page's player as Recommended download.
  • Each card shows the site and type, the available qualities (for example 1080p, 720p), the duration and number of segments, and a Download this video button that opens the download page.
  • Shows a calm Waiting for video card until a stream is found.

Choosing what to save

  • Pick any quality the source offers and, when available, a separate audio track.
  • The file name is taken from the page title (any language) and can be edited before saving.
  • Short streams need a confirmation so adverts are not saved by mistake.

Downloading

  • Up to 8 parallel requests with timeouts, retries and refresh of expiring links.
  • Low speed / Max speed per file, changeable during a download.
  • Live transfer speed, elapsed and remaining time; the tab title shows two letters and progress (for example MO…42%, MO…DONE!).
  • Large files are written straight to disk through the browser's save dialog (Chrome and Edge).

Output

  • HLS is saved as MP4 without re-encoding; direct files keep their original MP4 or WebM format.
  • Supports MPEG-TS (H.264/AAC), clear fragmented MP4, separate audio, byte ranges and AES-128 encrypted TS.

Interface

  • English, Thai, Japanese and Simplified Chinese; the choice is remembered.
  • Auto / Light / Dark theme switch, remembered and shared between the popup and download page.
  • Report button that saves a privacy-filtered JSON file for troubleshooting.
