In the process of learning how to make a video, we all make rookie mistakes. That is, unless we are warned about them. I made a lot of mistakes when I first began making science videos. However, I avoided some of the most common filming errors by reading about them or watching tutorials. I recently gave a lecture to a university class about how to make a video with a smartphone. This particular science course requires the students to make a video about one of the topics covered in the course. One of the topics I always cover in these lectures is common filming mistakes.
When I finished the lecture and was walking back to my car, the thought occurred to me that I could use my lecture presentation (made with Prezi) to make a helpful video about avoiding common filming mistakes. Later, I recorded that part of my lecture about filming mistakes with the screencapture software, Screenflow, along with my voiceover. All I had to do was play my presentation fullscreen on my computer while Screenflow recorded the screen and my voice. I then edited the footage in Screenflow to trim out unwanted sections and to insert The Scientist Videographer intro/outro at the beginning and end of the video. It took about fifteen minutes. My point is that recording your lectures, seminars, or conference presentations is a really easy way to make a video.
If you have a presentation made in PowerPoint, Prezi, Keynote, or some other application, you should be able to use that as the basis for a video about your science topic. Some journals are even encouraging authors to use this approach to create a video abstract that will accompany their scientific article. So, it may be worthwhile to know how to make a video this way.
Here is the video I made:
