My Science Videos

On this page, you will find links to some of my science videos. I’ve created and published several peer-reviewed videos through the science agency, the U.S. Geological Survey. These videos mainly focused on my research and were designed for a broad audience. In a few cases, I spotlighted the work of colleagues. In general, I tried to show how scientific research contributes to better conservation and management of our natural resources and how such information relates to the interests of the general public.  Also included on this page are videos showing other types of activities that scientists and students are involved in (for example, mentoring and conference attendance).

My other objective in making these videos was to show what it’s like to do scientific research and what real scientists look and sound like. I feel strongly that the average scientist needs to become more visible and familiar to the public. The average person is acquainted with doctors, lawyers, police officers, and other professionals, but most people have never met a scientist. Science videos are a great way to promote the value of scientific research while at the same time familiarize the public with the people behind the science.

Out of necessity, I did all of the story development, camerawork, narration, and editing and many of the animations for these videos. It was (and still is) a learning process. camcorder_klmckeeAfter an initial reluctance to spend time acquiring these skills, I found that I quickly and easily learned the techniques, which did not require expensive equipment/software or specialized training. What surprised me most, however, was how the process of making a short video about a topic forced me to reexamine what I knew about it (or thought I knew). New insights often occurred to me, for example, during interviews, researching background information, or putting the story together. Most of all, it was fun, and I rediscovered the passion for science and discovery that had become buried during years of competing for funds, for space in journals, and for recognition of technical accomplishments.

Note that all of these videos are free for anyone to use; all you have to do is grab the embed code (click on “share”, then “embed”, and copy the code) and insert the video into your website. All of the USGS videos went through an extensive peer and administrative review before they were approved for public release.

How to Make a Custom Thumbnail for Your YouTube Videos

When I first started making videos and uploading them to YouTube, I did not think much about how viewers made their decisions to click on one of my videos instead of one posted by someone else. In an Internet search, several videos may be suggested. People often decide on which one to watch based on the thumbnail image. One way to make your video stand out to viewers and tell them that your video is what they want to watch is with a custom thumbnail.

An eye-catching thumbnail is an easy way to attract viewers to your YouTube videos. If you’ve gone to the trouble of making a great video, then you shouldn’t hesitate to spend a bit more time to make sure people notice your video and decide to watch it. In a new tutorial (see player window below), I show how to design and create a custom thumbnail in PowerPoint and how to attach it to your YouTube video. Although Photoshop or Illustrator can be used for crafting the thumbnail image, many people do not have this software or do not know how to use it. In this tutorial, I use PowerPoint, which many people are familiar with, to create a custom thumbnail. Moreover, if you create a thumbnail template in PowerPoint, you can use it to quickly create thumbnails for all your videos.

But first, let’s go over some important information to help you design the best custom thumbnail for your video.

What is a thumbnail?

A thumbnail is a small image, often clickable, created for a webpage and that represents a file such as a photograph or a video. When someone conducts a search for a video, the thumbnail gives the viewer a visual preview of what your video is about. Some thumbnails stand out more than others. These are custom thumbnails. When you upload your video to YouTube, you are presented with three random frames from which to choose a thumbnail. Now, these are totally random, which means you basically get to choose among three really bad choices. Obviously, being able to create a custom thumbnail that best represents your video is preferable.

Who is eligible to use custom thumbnails?

Some forums suggest that you must become a YouTube Partner to enable advanced options like custom thumbnails. This is not true; if your channel is verified, you then become eligible to upload custom thumbnails. This option became available to me as a YouTube video creator in late 2013. Since then, crafting a custom thumbnail has become a routine part of my workflow when making a video. I consider it a key part of the process in creating an effective video and actually enjoy the challenge of finding just the right image and text design to use in the custom thumbnail.

What factors should be considered in designing a thumbnail?

  • First, take a look at other thumbnails for your topic and see what other video creators have used. Although this review will give you some ideas for crafting your thumbnail, you also want to take note of the features most often used and think of new ones to use for your thumbnail. In other words, you should try to design a thumbnail that stands out from the crowd.
  • Second, select an image that best represents your video. This image should be distinct but not misleading. Images featuring a person tend to attract the eye. If you can also show that person doing something related to the topic of the video, then your thumbnail image will be informative. For example, if your video is showing a scientific method, a photo of a person using an instrument or demonstrating the method is what you want. Those thumbnails featuring an image of a person jump out at you, which is why many people use them. However, you can also feature a photo of an instrument, an organism, a landscape, or a graphic—assuming it has something to do with the topic of your video. Planning ahead for the thumbnail and getting that photo while filming is the best approach. Failing this, you can extract a freeze frame from your raw footage. I show how to do this in the tutorial.
  • Third, resize and crop your image to ensure a good quality thumbnail that also meets specifications suggested by YouTube. In general, follow the rule of thirds to create a more interesting visual but mainly to allow space for text. YouTube suggests an image size of 1280 x 720 pixels, which is a 16:9 aspect ratio. You should keep the file at 2 MB or less and in an acceptable format such as jpg or png.
  • Fourth, add text to your video, which informs the viewer and reinforces what the video is about. Include keywords that people will use in their search. In many cases, all you need to do is restate the title of your video using a larger font and colors that make the text stand out.
  • Fifth, strive for a combination of an informative image and eye-catching text. In the tutorial below, I show some examples. You can make things easier on yourself if you use an image with some blank space in it, such as the sky, a solid fence or wall, as background for the text. In the tutorial, however, I show how to deal with a busy background.

What software should I use to create a custom thumbnail?

If you want to create a thumbnail from scratch, you have a number of options, including Photoshop, Illustrator, or PowerPoint. I’ve used PowerPoint in this tutorial because it’s a program that most science professionals use and are comfortable with. Photoshop and Illustrator are a bit more challenging to use and require some training and practice to use effectively. There are also online design sites that will assist you in creating a thumbnail. Canva is one example of a graphic design site, which offers templates and a user-friendly interface. I’ve not tried it, so can only recommend it as a possible site to check out. Although advertised as a “free” application, access to some key options seems to require a monthly subscription. In the end, you should use the software you are most comfortable with.

So with that bit of background, here is the tutorial showing how to create a thumbnail in PowerPoint (and direct link in case you can’t see the player window):
