Screencastify

I have been waiting on something like this for awhile.

I used this a few months back on a couple of class projects and was quite pleased with the ease of use.

Nice! It would be even better if you could select elements within the tab when you go to record, (eg, you could just select the youtube video panel) so that you don't need to crop. FastOne Capture does this really well

We used Screencastify to create a product walkthrough. It works really well, the other apps in the Chrome Store are inferior. Will probably upgrade to remove the watermark and go full screen for the final version. If you want to see a demo:

Does it work on Firefox :)

This looks great. Thanks for sharing

Nice and simple, great app !
