Microsoft has adopted the Chromium open source project in the development of Microsoft Edge on the desktop to create better web compatibility. This new Microsoft Edge runs on the same Chromium web engine as the Google Chrome browser, offering you best in class web compatibility and performance.
The new Chromium based Microsoft Edge is supported on all versions of Windows 7, Windows 8.1, Windows 10, Windows Server (2016 and above), Windows Server (2008 R2 to 2012 R2), and macOS.
In Microsoft Edge Beta, Dev, and Canary channels, you can enable or disable the Add video comments in PDF experimental flag that allows you to add YouTube videos and .webm format videos that are hosted online (like OneDrive, GDrive etc) to PDFs as comments. Edge will support inline playback of these videos.
This tutorial will show you how to enable or disable add video comments in PDF files opened in the Chromium based Microsoft Edge.
EXAMPLE: Add video comments in PDF in Microsoft Edge
Open Microsoft Edge.
Copy and paste edge://flags/#edge-video-comments-pdf into the address bar, and press . (see screenshot below)
Select Default (same as disabled), Enabled, or Disabled in the Add video comments in PDF drop menu for what you want, and click/tap on Restart to apply.
When finished, you can close the Experiments tab if you like.
