For today’s discussion, I decided to analyze a video by WIRED (2020) published on the official YouTube channel titled “Forensics Expert Explains How to Analyze Bloodstain Patterns.” The video touches upon how crime scene investigators and blood-stain analysts consider different factors to recreate the events of the crime (WIRED, 2020). The video goes through different difficulties of bloodstains, which helps to explain the view that a person needs very specific skills and much practice to analyze bloodstains.
The presenter uses almost all the effective presentation skills at the top level, as the YouTube channel is viewed by more than 11 million people, which demands high-quality videos. However, I wanted to focus on the two most powerful techniques. First, the presenter starts very strong, which grabs the attention of the audience. At the beginning of the video, the presenter smashes a bloodstain with a hammer and says, “there we go,” with relief. Such actions make the viewer wonder why hitting blood with the hammer can be so relieving. Second, the presenter always maintains eye contact with the camera and talks with a smile, which makes the viewer feel important and relaxed.
However, there are two presentation skills that can be improved. First, the presenter uses the visual aid ineffectively. Sometimes, when he talks, the video demonstrates pictures irrelevant to what he is talking about. This distracts attention and makes the viewer focus on the picture rather than on words, while the picture may be unimportant. As a result, the viewer may miss crucial information. Second, the presenter goes into very specific details and calculations using professional language. While this may be important for the prepared viewer, casual viewers may become confused. However, even though there are some areas of improvement, the presenter is nearly perfect in terms of using presentation skills.
