Texts

• Required
• Digital Video: A Technical Primer of Digital Video Techniques. Available from http://www.eacademicbooks.com/dvbook.asp
• Any reference book on your choice of composting package
• Access to a Digital Video camera.
  • If you do not have a digital video camera, you get check out cameras from the DLC. A few limited cameras are available from Knoy 346.

Material Submittal:

• Projects:
• Projects are to be turned in via the class's YouTube account (www.YouTube.com/CGT346). The "description" field for your video on YouTube should contain (a) a description of the project [Project 1 Spring 2011], and (b) the names of all group members.
• For projects the class will be divided into approximately 6 groups.
• Presentations
• Along with each project, you will be required to perform a series of presentations that approximate real-world interactions with a client. The main purpose of these presentations is to provide you feedback. Thus, you will be graded on your presentation skills, content, and feedback that you provide other groups.
• Homeowork Assignments:
• Homework assignments from the Ballinger book are to be turned in through the eAcademicBooks site by 9:00 PM Wednesday of the week in which the assignments are given. For example, the first day of class will be Tuesday, Jan 8, 2013. The first set of assignments will be due by 9:00 PM on Wednesday, Jan 9, 2013. The readings and assignments are typically separate from the materials covered in class. This arrangement allows us to discuss any problems during the Thursday class meetings.
  
  The eAcademicBooks site allows you to continuously resubmit your assignment (to yourself) until you get a 100%. Take advantage of this feature. At 9:01 PM, on Wednesdays the site will send a report and a copy of all of the assignments to your TA and professor. Do not send them your Ballinger-assignments directly, as they will not be considered for a grade. Please take into account that the server may be busy close to the turn-in time. If you hit the submit button at 8:58 PM and the server does not process your assignment until 9:01 PM, you will not get credit. Plan accordingly. Do your work early.
