Create fake chat conversation and download it as a video

Just created this app, it lets you create fake chat and then download video of the entire chat in mp4 format. You control both sides in conversation. I personally needed something like this but couldn't find anything on the web that can generate video of the conversation. Before I push it to production, I would like to hear some feedback from you, is this something you would want to use? I will attach link to resulting demo video here for anyone interested. http://chattlr.com/demo.mp4
