Tella.tv recordings expire. A product demo from last quarter, an onboarding walkthrough from your manager. Tella is great for making recordings, but there is no guarantee they will be available when you need them again. This extension creates permanent copies. Press play on any Tella recording, click the download button that appears on the video, and save it as an MP4 file on your computer. It works on Tella's own site and on embedded Tella videos in Notion pages, wikis, or internal docs. If a link goes stale mid-download, the extension automatically refreshes it and picks up where it left off. Three free downloads are included. The download manager tracks progress across tabs, and everything runs locally in your browser. Your recordings are never uploaded to any outside service.
Key Features
- Detects signed CloudFront HLS manifests from prod-stream.tella.tv once playback begins.
- Works on Tella pages and embedded Tella videos found inside iframes and third-party websites.
- Places an overlay download button directly on detected players so you can start from the video itself.
- Uses multi-pass manifest discovery with frame scanning, HTML checks, and playback warmup for harder embeds.
- Refreshes expired or stale signed URLs by reopening supporting views and reacquiring a fresh manifest.
- Converts signed HLS streams to MP4 in an offscreen context without requiring ffmpeg or desktop software.
- Shows download progress, speed, and task status in the built-in download manager with cross-tab sync.
- Uses the browser Save As dialog so you can choose exactly where the final MP4 should be stored.
- Keeps quality selection tied to the renditions exposed by the Tella manifest instead of forcing a single output.
- Supports Chrome, Edge, Firefox, Brave, Opera, Whale, and Yandex on desktop operating systems.
- Includes 3 free downloads after secure email OTP activation before the paid subscription is required.
- Processes video locally in your browser with no media upload to outside servers.
Customer Reviews
Clara Whitfield
I use Tella for onboarding walkthroughs and this extension gives me dependable local MP4 backups without any manual stream work.

Marcus Ellison
Our team shares Tella videos in Notion and internal docs. This catches the embeds, handles expired links, and keeps the workflow simple.

Priya Mehta
Generic downloaders kept failing on the signed manifests. This one detects the video right after playback starts and the Save As flow is straightforward.
