2e

Split Screen

Cut the screen in half to allow for two camera shots at the same time (no overlapping)

Define the following:

3a

White Balance

Color temperature of the image. Setting depends on the lighting available.

3b

Light Screen

4c

Frame

A complete video picture composed of two fields (two complete interlaced scans of the monitor screen). A frame consists of 525 interlaced horizontal lines of picture information in NTSC, 625 in PAL.

3h

Input Selector

A routing switcher or auxiliary bus used to expand the number of video or key inputs that can feed an input of a digital picture manipulator or keyer. Many keyers only accept one key source and fill, but by connecting an input selector to those inputs, many more source and fill signals become available just by selecting cross points on the input selector.

3i

Monitor

In video, a device that directly displays a video picture from a camera, videotape recorder, special-effects generator, or video switcher output. This is typically multiple screens, one for each of the inputs and one for the final monitoring display.

3j

Media

Livestream

Livestreaming refers to online streaming media simultaneously recorded and broadcast in real-time. It is often referred to simply as streaming.

List some of the advantages and disadvantages of two different video file formats.

• avi-Audio Video Interleave file
• mov-Apple QuickTime Movie
• mp4-MPEG-4 Video File
• wmv-Windows Media formats
• etc.

Describe the effects of lighting on a media production. How can lighting be adjusted to achieve the desired effects?

All video uses some sort of lighting, whether it be natural light (from the sun) or artificial lights. The goal of video lighting is to choose the best source(s) to achieve your goals.

First and foremost you need enough light. You must ensure that your camera is able to record an acceptable picture in the conditions. With modern cameras this is seldom a problem except in very low light or strong contrast.

Assuming you have enough light, you must then consider the quality of the light and how the various light sources combine to produce the image.

When moving between locations, think about what light source you are using. If you move from an outside setting to an inside one with artificial lights, the amount of light may seem the same but the color temperature will change according to the type of lights. In this case you need to white balance your camera for the new light source.

Read Daniel 12:4 and Mark 16:15 and discuss how video can be used to increase knowledge and preach the gospel to all creation.

“But you, Daniel, shut up the words, and seal the book until the time of the end; many shall run to and fro, and knowledge shall increase.”
— Daniel 12:4 (NKJV)

And He said to them, "Go into all the world and preach the gospel to every creature."
— Mark 16:15 (NKJV)

When Daniel penned his text, he indicated that there would be an increase in knowledge. In order to witness “live” what was happening, one had to be “present.” Today, we can witness “live” events through multiple media.

We are now able to fulfill what Jesus said in Mark 16:15 by using media technology to reach places that Christians are forbidden to enter vía the Internet and satellite.
