Feature walkthrough with annotations

Our design team at Console Connect has started to create walkthrough videos with annotations to explain to stakeholders and developers how a new feature will work. The Hifi version of this (pictured) is the final culmination of the design effort of the feature and used as a guide (in conjunction with user stories) for implementation and test.

This is going back a few iterations of the product, but I wanted to post a part of our process when developing a new feature and this was a great example.

Sorry bout the jerky quality of the video. Internally we just do a screen recording of the Invision prototype using Quicktime.

Make sure to see this at 2x to properly see the details.

What do you think of this approach?
