  2. 2. Videocasting, Screencasting and Live Streaming 2 Podcasting, blogs, and RSS are technologies rooted in the idea that broadcasts can be created and made available to listeners at their convenience. Technology makes it possible to use. Web 2.0 concepts enable businesses to reach their customers and stakeholders in real time via video. The idea of synchronous communication on the web has captured the imagination of many developers who have introduced products ranging from live radio broadcasting software to television-like live streaming sites.
  3. 3. What is Videocasting? 3 Videocasting (also called vodcasting) adds a visual element to podcasting Can be created with inexpensive digital video technology. High-quality visual media can be created with video cameras, various editing software and an internet connection. Video production ranges in cost from nearly free (e.g. using a webcam or mobile phone camera to capture and post video) to high budget production
  4. 4. Digital Video 4 Developed with a wide range of cameras including the inexpensive and widely used Flip (, webcam, or video recorder on a mobile device such as an iPhone or iPad.

  6. 6. Video Considerations 6 Lens Size: Larger lens enhances light and provides better quality. Video Pixels and Resolution: Pixel is the smallest addressable screen element in a video device. More pixels in an image result in a higher video resolution. Audio Considerations: Digital camcorders come with built-in microphones. In many instances it is necessary to attach an external microphone for better sound quality or for recording interviews more effectively. Image Stabilization: Stabilization keeps images from shaking and bouncing around when recording action sequences. (Optical stabilization better!)

  9. 9. Lighting Guidelines 9 Lighting and sound do not need to be perfect depending on your goals. Sometimes an amateur look/feel is desired to make video more personal and ‘realistic’. Several guidelines can improve the quality of a recording. First, avoid recording directly beneath a bright light that causes shadows to be cast over the speaker’s face. Second, be sure the location is evenly lit with multiple light sources. Third, avoid locations where light levels may change rapidly or shadows may be occasionally cast.
  10. 10. Computer Considerations 10 Computer system must manage and manipulate large amounts of data. In general, this means have a fast microprocessor and plenty of RAM as well as sufficient hard disk storage space
  11. 11. Preparing to Record a Videocast 11 Storyboards often are the starting point for a videocast. The storyboard provides a working plan with details specifying how a video director envisions the end product.

  15. 15. Video Software and Editing (con’t) Video editing software comes in many different categories and cost ranges.
