MS Teams Video & Transcript Downloader

Download MS Teams meeting videos and transcripts. Multiple formats (JSON, VTT, Grouped). In-browser.

MS Teams Video & Transcript Downloader is a Chrome extension that solves a common frustration: downloading Microsoft Teams meeting recordings, transcripts, and shared Microsoft Stream videos when the download button is disabled, missing, or limited by organizational permissions. Whether you need to save a recording for offline viewing, extract audio for a podcast, grab a transcript for notes, or download an MP4 someone uploaded to SharePoint or OneDrive — this extension gives you full access. THE PROBLEM WE SOLVE Microsoft Teams, SharePoint, and Microsoft Stream often restrict downloads based on organizational permissions or meeting settings. Even when you can view a recording or transcript, the download button may be disabled, missing, or limited. This leaves users unable to: - Save meeting recordings for offline viewing - Extract audio from meetings - Download transcripts for reference - Process transcripts with AI tools - Create subtitles or captions - Keep a copy of a video a colleague uploaded to Stream / SharePoint / OneDrive WHERE IT WORKS - teams.microsoft.com and teams.cloud.microsoft (the Teams web client) - *.sharepoint.com meeting-recording links - The Stream-on-SharePoint player at *.sharepoint.com/.../_layouts/15/stream.aspx — used whenever an MP4 lives on SharePoint or OneDrive (Microsoft retired the standalone Stream Classic at web.microsoftstream.com in early 2024. The current Stream product reuses the SharePoint player, which this extension covers automatically.) VIDEO & AUDIO DOWNLOAD A red "Download Video" button appears in the top command bar of any recording. Click it, pick a format, and the file lands in your Downloads folder. No external tools. Three format options: 🎬 Video + Audio (.mp4) — Best quality, original streams copied 🎵 Audio Only (.m4a) — Original audio, no re-encoding 🎬 Video Only (.mp4) — No audio track Performance: - Segments fetched in parallel with a tunable concurrency selector (1 / 2 / 4 / 8 / 16). Default 4 keeps tenant-throttling risk low. - Automatic 429 / Retry-After backoff if SharePoint pushes back — no failed downloads from transient throttling. - Multi-track mux runs off the UI thread in a Web Worker, so long recordings don't freeze the tab. - Encrypted segments (SharePoint's newer "SEA" AES-128-CBC encryption) are decrypted automatically. If a recording is hard-DRM-protected (Widevine / PlayReady / FairPlay), the extension detects this and shows a clear dialog instead of producing a broken file. Real DRM content cannot be downloaded by any client-side tool — only by the browser's built-in DRM module during playback. TRANSCRIPT DOWNLOAD Three professional formats: 📋 RAW JSON (.json) - Original Microsoft Stream format with complete metadata - Full speaker display names, precise timestamps, entry IDs - Perfect for developers and advanced processing 📝 VTT Format (.vtt) - Standard WebVTT subtitle format with timestamps - Speaker voice tags - Works with most video players and subtitle editors 🤖 Grouped Text (.txt) - Consecutive messages from the same speaker collapsed into a block - Clean, readable format optimized for LLMs and human reading - Easy to scan and summarise How it works: - Click the "Transcript" tab on a recording page - A purple "Download Transcript" button appears in the transcript panel - Click it to see live previews of all three formats - Choose your format, customize the filename, and download If the meeting was never transcribed, the extension shows a clear "no transcript available" dialog rather than silently failing. KEY FEATURES - Live format previews before downloading - Editable filename with auto-detection from meeting titles - Last-used format remembered as the default - Speaker names preserved in all transcript formats (not anonymous GUIDs) - Floating banner widget as a fallback when SharePoint hides or re-renders the command bar - Automatic dark mode that follows your system / browser preference - DRM detection — shows a clear dialog rather than producing an unplayable file - No-transcript detection — clear feedback when a meeting was never transcribed - Works on Teams web, SharePoint recordings, OneDrive-shared MP4s, and the Stream-on-SharePoint player HOW TO USE 1. Install the extension from the Chrome Web Store. 2. Open a meeting recording or shared video in Teams, SharePoint, or the Stream player. 3. For video: click "Download Video" in the command bar (or the floating banner). Pick a format and click Download — the file lands in your Downloads folder. Tune the "Parallel segment downloads" selector if you want faster (higher) or gentler-on-throttling (lower) downloads. 4. For transcripts: click the Transcript tab, then "Download Transcript", choose a format, and save.
