I Introduction and Background:

Alessi and Trollip (2001) stated that the use of video in computer software can add a professional look to any program. If used correctly, it can be engaging and even entertaining to users. It also makes the software program stand out from software programsnot have videos. Last, video can add visuals to aide news stories, instructional guides, how-to-programs, etc. However, improper use of video may damage the professional look of any program. Video can also be expensive and time consuming to create. They also require high performance computers to process and play. Video can also be distracting if there are too many components, difficult to use, or not designed for the target users.

In this wiki research you will learn about the different types of video editing methods. You will also find information about the types of digital and computer video editing software if you are interested in creating your own video. You will also read about the positive and negative effects of learning with video. Next, you will read about a study in which video was used to educate students. Lastly, you will read some recommendations on how to to use video effectively.


II Types of Video Editing Methods

There are several ways of adding video to a program. Many editors use digital non-linear editing for most projects.

1. Film Splicing. This method involves cutting footage of film and rearranging them together for the desired results. This is done with a splicing machine. We see examples of this everywhere such as commercials and movie trailers. Below is a video from YouTube showing how a splicing machine works.


2.Tape to Tape. Although not the most common video editing method, Tape to Tape is still in use. In linear editing (starting from the first shot and working to the last shot), video is copied from one tape to another using two or more video machines that are connected to each other. An example of this would be making a video montage of home videos. My cousins have done this in the past. They took home videos that were long and tedious and made another tape using only the parts they liked.
3. Digital/Computer. In this non-linear method, video footage is first recorded on a computer hard drive. Then it gets edited using a special video software program. Although it is flexible, one of the challenges of digital video is dealing with software and hardware compatibility.



III Types of Digital/Computer Video Editing Software

Most video editing nowadays is done digitally using the computer. The following list from Wikipedia shows the various programs users can work with in producing video for computer software and film.

Some of the software available to consumers in this list include:


Below is an example of what one program looks like. This one is from Avs4You.

IV Positive Effects of Video in Computer Software:

  • Adds a professional look to a program.
  • Engaging and entertaining for users.
  • Makes the program more memorable and thought provoking,
  • Adds visual aides to news stories, world events, etc.



V Negative Effects of Video in Computer Software:

  • Can be expensive to produce
  • Time consuming
  • Can damage the professional look of a program if not done properly
  • Requires high performance computers to run videos
  • Can distract learners


VI Video in Education

An article by Shumack (2011), video is used in physical education classes. Coaches demonstrate different skills in a vodcasts, discuss rules, and strategies. Students then may practice these skills outside of school at their convenience. One of the benefits of video in physical education is that it allows for students to learn through audio and visuals. Another benefit is that students can make up missed practices due to an absence. Creating a vodcast is relatively simple. One would need a computer that is able to run Windows Live Movie Maker, Garage Band, Audacity, or Camtasia. In addition, a video camera and microphone are needed for audio and visual. Vodcasts can then be posted online for students to access at anytime.


VII Recommendations for Use of Video in Computer Software Design:

According to Alessi and Trollip (2001) video should be designed and used correctly in order to be effective. The following list suggests recommendations for effective video use.

  • Use it for important information
  • Keep video presentations short
  • Use video for demonstrating and modeling
  • Consider the cost of video production
  • Provide user controls such as pausing, replaying, and skipping.
