    Erik Runge's B-Roll Video Analysis

    After a short and brief anchor introduction WGN’s, Erik Runge, tells his story on the upcoming bad allergy season through a donut live shot. In his introduction live shot, Runge stumbles a bit, but then quickly recovers from it by restating the word and pretending like it never happened. Runge’s b-roll video that was shot in the same perimeter just through different angles around the same lake area in Lincoln Park was lacking and did not compliment the story well at all. Some close up b-roll on growing plants was more effective than the other videos because it represented pollen, a main cause of allergies. Runge also only followed around one allergy victim who did not have many powerful things to say beyond the obvious negative comments on…

    Forbidden Knowledge Video Analysis

    When building many of the castles in the 1300-1400’s the main purpose was to keep the enemies out and of course for conquest. In the video I watched, the Forbidden Knowledge video, they called out some very key point of why and how these fortresses and castles where erected and defended. Not only where there kings of the lands, but then each of those lands were divided up to noble kin and lords. They were always trying to better there futures with more land, even if that included killing your own cousin to get his piece of land. One great example of an intuitive fortress, Caesar had made a donut shaped fortress at one point around a small town; he shut out and was starving the people in the town and then also keeping out the men that were…

    Video Analysis: The Ted Talk

    In the Ted Talk, Jeff Iliff describes different ways that our bodies, more specifically our internal organs, secrete waste and how this process differs in the two percent of our bodies that is the brain (2014). Iliff also stresses the importance of learning about healthy sleep patterns by mentioning the fact that we spend nearly one-third of our lives sleeping (2014). Furthermore, the video describes a process that occurs in our brains, in order to secret waste that may be lying between various cells (Iliff, 2014). When we are awake, there is very little cerebrospinal fluid (CFS) flowing through the brain. However, whenever we are sleep, there tends to be an influx of CFS flowing throughout the brain, which is what scientists are calling waste…

    Dualism: Video Analysis

    After seeing the video I believe that one of the solutions sort of works, Dualism simply because I went to a catholic school and raised to be religious. I was always taught believe that if someone or myself does something “evil” that we let the devil affect our judgment or listen to the devil to do something wrong such as fight with siblings, steal or cheating. Although, some believe there are issues with this solution because if god has great power, knowledge and all good intentions, then why doesn’t he stop all evil/ devil. I think god uses evil as a scare tactic, represented as a figure to attempt keep individuals from doing something evil and staying on the right and good path that God would want us to follow. Overall keeping individuals…

    Short Music Video Analysis

    For my creative media project, I put together a short music video. I decided to make a music video because I felt is was significant to a problem in todays society. Today, popular culture, such as today’s hits music, has a negative impact on women and young girls. For example, in a lot of songs with a male artist, the male will degrade women. With that said, one may turn on the radio, or television, and hear a song about how the male artist is so wealthy that he can sleep around with any girl that he would like. In the music video of the same song, one may see a women, wearing little or no clothing, dancing seductively on the artist. This is very alarming to our youth of girls. Because of the lyrics and music videos, young girls will look up…
