Can You Make a One-Minute Science Video and Why Would You Try?

I was talking to a colleague the other day about making videos to demonstrate a sampling technique. When I suggested to him that it was possible to create such a video and keep it short–around a minute in length, he expressed disbelief. He questioned (1) why you would need to do such a short video in the first place and (2) whether you could even get your message across in a minute.

I explained, in response to his first point, that the shorter the video the more likely the viewer would watch the entire thing. If you’ve been reading this blog, you know that one of the key features of a successful video is brevity–typically under three minutes, but around one minute is considered by some to be an ideal length. Some statistics seem to suggest that viewers watch an average 30-second video 85% of the way through, with many of them sticking around until the end, whereas most viewers will watch only 50% of a 2-minute video. In other words, shorter videos are more engaging to the average viewer.

One point that occurs to me and that video analytics don’t seem to consider is that these statistics reflect how all viewers react to the video, rather than how the target audience is responding. Many people will click on a video link out of curiosity but find that it is not what they are looking for. Sometimes this decision is made in the first second or two but may also take a bit longer. These people were not your target audience. What would be useful is information about how engaged the target audience is in a video. Video analytics (such as those above) do not distinguish the target from non-target audience (and I’m not sure how easy this would be to do anyway). Someone who is only marginally interested in a topic is much more likely to prefer a shorter video, whereas someone committed to learning something will be willing to invest more time. Statistics seem to suggest that there’s not much difference in viewer engagement between a 4-minute video and a 10-minute video. Viewers who stick around for 4 minutes are likely to watch a longer video through to the end. This insight is important especially for an instructional video. Someone intent on learning a technique will likely be willing to watch the entire video.

In addition, it is sometimes impossible to explain a complex topic in one minute. In that case, you should take the time necessary but put your most important information as close to the beginning as possible, similar to how journalists write news articles. An instructional video also may need to be a bit slower to allow the viewer time to absorb the information, adding to the length. The point is that you should keep your target audience in mind when deciding on length, especially for an instructional video.

Nonetheless, if you can get your instruction across in one minute or less, you should not drag it out any longer than that. Besides the direct effect on viewer engagement due to length, striving to keep the video short encourages you to be more creative and to eliminate extraneous material that just bog things down, which will also have a positive effect on viewer engagement. In fact, I suspect that the latter effect on the quality of the video is often what makes shorter videos more engaging than longer ones. For the scientist videographer, however, this means more work to simplify things sufficiently (without sacrificing accuracy) and to package the information in a more entertaining way.

As to whether a video describing a complex science topic can be done successfully in a minute or less, there are plenty of examples (check out MinutePhysics). But what about a video describing a sampling technique? In the next post, I will critique a 1-minute science video that describes a common sampling method in ecology.

How to Create a Science Video with your iPhone

Scientists and students:  How much time would you invest to learn how to produce an informative and effective science video, requiring only an iPhone or other Smartphone that shoots video? In this new 15 minute tutorial, you can learn how to plan, shoot, edit, and share a professional-looking video that describes a research project, an important science topic or research finding, or a new method.

Such videos can then be used to meet the Broader Impacts criterion of the National Science Foundation or other funding agency, as supplemental online information for your journal publications, or just to enhance your website and show off your work.

All you need is an iPhone or other Smartphone that shoots video and supports the necessary software to edit the footage. Note that this tutorial is different from the one I previously posted, which used the Videolicious app. In this tutorial, I use the iMovie app for the iPhone (download from the App Store) and briefly show how to navigate the program to create a movie project.

Check it out:

There are other movie-editing apps and, of course, professional editing software that provide more bells and whistles, but these take more time to learn and are more expensive. The iMovie app for the iPhone is designed to use video shot with the iPhone, but you can also import media shot with a camcorder or digital camera (I use iTunes to transfer files from iPhoto to my iPhone camera roll). You will also notice that I included some animations that I created with PowerPoint and Photoshop, exported as movies, and uploaded to my iPhone. See previous tutorials for more information about doing animations in Powerpoint here and here.

Even though most of my videos are shot with a camcorder and edited on my computer with professional software, I increasingly find it easy and convenient to use my iPhone to capture video on the go and to quickly edit the footage and upload to a video-sharing site. As the cameras on these smartphones have improved, the quality of the images has gotten better and better. There has even been a full-length movie shot with a Smartphone (Nokia): go here to see the trailer and behind-the-scenes footage.

I hope you find this tutorial helpful and inspires you to use your iPhone or Smartphone to produce videos about your science projects.

How Not To Make A Science Video

As we know, explaining complicated science concepts and implications of research findings in a way that is understandable, interesting, and entertaining to diverse audiences is not easy. One of the important science issues of the day, which decision-makers and the general public need to understand, is climate change. Several organizations, such as RealClimate, have attempted to communicate climate science via their websites, blogs, and other media.

This past spring (2012), the World Resources Institute (WRI), supported by google.org, ran a survey to find out which type of video format (“webcam”, “conversation”, and “whiteboard”) worked best for scientists to get across some complex information about climate change. Three scientists, Paul Higgins (American Meteorological Society), Brian Helmuth (University of South Carolina), and Andy Dessler (Texas A&M), were recruited for the project. For the “webcam” version, all three scientists filmed their own videos. The “conversation” version was composed of a slideshow with the scientists’ voiceover. The “whiteboard” videos were filmed at the WRI’s offices, where each scientist conducted their talk using a whiteboard to illustrate their points.

You can see all the videos here, but I’ve inserted three below (by Paul Higgins) so you can see how well (or not) they worked. Then, about 1500 people voted on which ones that most effectively communicated the science topic.

As you can see, none is very effective at communicating the science of climate change. And that’s not just my opinion. If you read the review comments, you see that a number of viewers thought the videos failed to engage. One commenter suggested, tongue-in-cheek, that the bad videos were a ploy to get donations to make more professional videos about climate change (give us money or we’ll use these videos to communicate climate science to the public!). I actually had similar thoughts upon viewing these awkward and very dull presentations.

Also like the above commenter, I am not trying to disparage the scientists who participated in this project. They were given poor options of bad, bad, and worse, so no wonder they did not do well. Few of us could do better, given these three choices. The videos done by Dr. Helmuth were marginally better because he seems to be a bit less “stuck in his head” than Dr. Higgins; also, his topic (climate change effects on sea stars) is a bit more accessible to the average person than the carbon cycle. If you are a scientist and your topic deals with more abstract concepts, then you will have to work harder than someone who studies charismatic organisms or ecosystems, e.g., the Giant Panda or coral reefs.

Much better videos about climate change have been produced by Peter Sinclair (Climate Crock of the Week), which are usually well-done, include data from peer-reviewed publications as well as interviews with real scientists explaining their work and clips from the media and movies that add some humor and entertainment to the topic. Even the ones he’s done that are mostly composed of interviews with scientists are more engaging than the WRI videos. The most recent such video shot at the 2012 American Geophysical Union conference, even features one of the WRI scientists, Dr. Andrew Dressler, who comes across much better in this off-the-cuff interview than in the WRI videos.

Note how Sinclair inter-cuts footage, images, and graphics to supplement and support what the interviewees are saying. Not as well done as some of his other videos but the video has a spontaneous, unrehearsed feel to it, and most of the scientists sound sincere and natural in their comments.

I was additionally annoyed by the fact that the scientists selected for the WRI exercise were all older white males. I mean, really, couldn’t they find one female or minority to record a set of videos? If you are trying to reach a diverse audience, you need to show scientists to whom viewers can relate. A perfect example is the video of Katharine Hayhoe (a real climate scientist) answering 10 questions about her work and her religious beliefs:

Now, Dr. Hayhoe’s video was not designed to explain climate science or research findings and is not directly comparable to the WRI videos in that aspect. My point in showing it, however, is to emphasize how important it is for the scientist to be engaging and believable (as opposed to being preachy or appearing to have an agenda)….if you are going to do a “talking heads” type of video. Also, having a scientist with whom your target audience can relate (young or religious people, for example) is key to effectively communicating your message.

The intended audience of Dr. Hayhoe’s video was clearly people with strong religious beliefs and who’ve been targeted by the climate science misinformation campaign. The WRI videos are less clear about their target audience and appear to suffer from the common problem of the scientist failing to understand their audience (or expecting the audience to educate themselves so that they can understand the video topic). Most scientists think that facts, facts, and more facts are what is convincing to non-scientists, when the reverse is more often the case. Note how the video with Dr. Hayhoe focused on her beliefs, emotions, and humor….all effective in reaching the viewer at more than just an intellectual level. The scientists in the WRI videos appear to be robotic by comparison. Only after the viewer has come to “know” and “like” Dr. Hayhoe does the video ask and have her answer the key question: Is climate change real and are humans causing it?

If you must have a senior scientist explaining the main points, then have segments showing younger scientists or students working in the lab or field or, better yet, explaining their interest in the topic and why they’ve chosen to work on it. This approach will at least have some person with whom the younger or non-scientist viewer can relate. Unless you’re a TED-worthy speaker, capable of entrancing an audience by talking about incredible ideas or innovations, then you can’t do a video with just you talking.

The WRI videos followed few of the guidelines we’ve been discussing on this site, whereas the one with Katharine Hayhoe did, especially in terms of reaching an audience at an emotional level. In future posts, I’ll do a more in-depth assessment of these videos and why they did or did not work well.

Finally, it seemed that the idea for the WRI videos was to survey formats that scientists, with their apparent lack of videography skills, might use. Well, if these are the only options, scientists just shouldn’t bother and leave the filmmaking to professionals. However, as I’ve tried to demonstrate with this blog, most scientists can learn enough basics about filming and editing to create very effective videos.

Use Online Interviews in Your Science Video

An effective technique to use when you cannot afford to interview your subject in person or at their field site, is to do an online interview via Skype or similar service. You can record your computer screen while your interviewee answers your questions online. Then all you have to do is edit in footage and still images illustrating the points that your subject mentions. Here is an example of one such video:

Birds of Paradise

Take a look at this video on birds of paradise and the scientist and photographer who have been documenting them. It was produced by the Cornell Lab of Ornithology. This and numerous other videos on the Cornell website illustrate how a university can advertise the research being done by staff and faculty in a format that’s interesting and accessible to the general public.
