In Microsoft Team Foundation Server (TFS) bug reporting tool it is not so simple to add recorded videos of bug. To record bug scenarios can be very time effective for a developer when receiving the bug reports.
The best way, as we use in my current project/assignment, is to record the bug with a tool called ScreenToGif. Is is very simple to record your movement on the screen and convert the small video to an animated GIF image.
The animated GIF image can then be imported (added) as a image direct in the TFS bug report and can be viewed without any tools direct in the web TFS web interface.
I can highly recommend this way of working with bugs in TFS!
