This is great when you are creating flipped videos and lesson for students. I also like that you are able to screen share as well as add your own image/picture in picture to this. This is great because it is very simple to share it out or give someone access to this recording. The best feature is that Screencastify is a Google extension that can record right from your web browser and then save directly to your Google Drive. This frees me up to spend more time conferencing with other students. This allows me to create lessons around common issues so that students can go back and watch them whenever they need to. I love being able to create flipped lessons for my students and staff with this tool and that it simply saves them to my Google Drive for easy access. The free version also adds a watermark to the videos but its small and in the corner and you hardly ever notice it. There is a limit to the length of the videos and you can only record a certain number of videos a month unless if you pay of course. It doesn't take much space and it is very easy to understand on the first go. I simply record my procedure and send the google drive link to everyone and they can view it wherever they are and whenever they please, repeating it, pausing it and downloading it like any other video. And that is it! I love using it for when I need to explain how I use whatever new software my company is trying to adopt and it helps me record the process so that I don't need to repeat myself when teaching others how to use the new software. Once done you just click on the extension button again and select the 'stop recording' option and it gets saved automatically to your google drive if you are online and when you are offline it will just save it to your computer. This is great for tutorials and how-to videos.

Once you hit zero you can start speaking and showing others whatever you want. And yes, you are able to choose how long you want the countdown to be. Just download the extension and viola! Whenever you need to record your screen with voice-over just click on the extension, choose your preferences, click record select which tab or screen (if you have multiple screens like I do) and wait for the countdown. I show them step by step on what to do so that there is no room for misunderstandings and everyone is on the same page. I use it mostly to record any procedures or even any task that I want others to get done.
