This document summarizes key aspects of videocasting, screencasting, and live streaming discussed in Chapter 5 Part A. It discusses how these technologies enable synchronous communication on the web in real time via video. It then defines videocasting, discusses considerations for video and audio quality as well as lighting, and provides examples of video editing software options ranging from free to higher-end programs. The chapter emphasizes that video production can range from nearly free using basic equipment to higher budget productions.

2. Videocasting, Screencasting and Live Streaming
Podcasting, blogs, and RSS are technologies rooted in the idea that
2
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. 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

Digital
Video
Developed with a wide range of cameras including the inexpensive
and widely used Flip (http://www.theflip.com), webcam, or video
recorder on a mobile device such as an iPhone or iPad. Canon,
Panasonic, and Sony all offer a wide range of excellent mid-price
video camcorders. Videomaker provides excellent insight.

6. Video Considerations
Lens Size: Larger lens enhances light and provides better quality.
6
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!)

7 Microphones

8. Lighting
8
Professional lights can be purchased at a reasonable price. Lights
help eliminate shadows and even out the video’s appearance. Many
companies provide low-cost, studio lighting solutions. An example is
http://www.coollights.biz.

9. Lighting Guidelines
9 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.
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’.

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. 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.

12. Following completion of a storyboard, a shot list can be developed

14. Video Software and Editing
After shooting video using a
camcorder or other device, the raw
file is transferred to a computer.
Raw file needs to be edited and put
into a form that is suitable for a
videocast.
This includes adding title screens,
music, commentary, and arranging
the various shots in a meaningful way.

15. Video Software and Editing (con’t)
Video editing software comes in
many different categories and
cost ranges.
Both Windows and Apple OS
generally provide free editing
software: MovieMaker and iMovie.
Most digital video cameras
include software with editing
features.
A third low cost option is to
investigate online video editing
service.

16. Low Cost Video Editors Examples
The raw file needs to be edited
and put into a form that is
suitable for a videocast. This
means adding title screens,
music, commentary, and
arranging the various shots in a
meaningful way.
