Previously, every time I launched a new product, I had to create a video demo to show the users how the product works and often end up with many versions from various angles. Those are tedious and yet hard work since operating the product while explaining how it works precisely according to a script is not easy. There were many back and forth. Once that's been done, editing the video is another time consuming part, not to mention putting together the voiceover and background music which basically requires a professional studio to come out an ideal one.
