Multi Source edit Systems

–Allow you to perform dissolves, wipes, keys and other transitions

•Fade

– Gradual transition of an image to or from black

•Kissing Black/ Dip to Black

– A quick Fade to black and back up.

Dissolve

• A gradual transition from one image into another

Dissolves

• Need extra head and tail of shot

• If you need to dissolve between shots in one tape, a dub will have to be made.

• Used to compress time

• Used to show thematic and structural relationships

• Subtle effect/ blend action

• Dramatic pause

• Cover lapses of time

• Locale changes

Soft Cut

• Quick Dissolve

Superimpostion

• Half of both pictures are seen simultaneously

Wipe

• When one image pushes the other off the screen.

Split Screen

• shots share parts of the screen

Digital Video Effects

• Are special effects for video production created by digitizing and then manipulation an image.

– Control image size

– Aspect ratio

– Control movement along x,y, and z axis

– Image look

– Split an image

Keys

• Are the common way for superimposing titles and for creating special effects. Replace images from one shot with images of another shot.

• Keys combine images by switching back and forth during the scanning process with the trigger to switch being created by the luminance level or color.-

• Must select one image to be the foreground and the other image as a background

Chroma

• In a chroma key all of one color is removed from the main image and is replaced with the second- weather person

Graphics

• Plan for graphics before shooting

• Make sure that they fit the screen correctly, by monitoring.

• Stay away from highly saturated colors and fine lines-generation loss shows

• Font should be consistent throughout program

• Use Drop shadows

TBC

• Time Base Corrector

• Used to correct color and timing errors in video

• Eliminates errors created in VTR playback

• Can separate video signal to adjust level, chroma, and hue separately_ Color correction

• Can have a dropout compensator to cover up flecks

• Can have still store- what is still store-

• Adds noise to signal

Waveform Monitor

• Displays parts of the video signal- picture and sync information

• Used to look at luminance levels of your picture

• Measures in IRE’s

• 100 IRE is…….

• 7.5 IRE is……….

• Final Cut Pro measures in percentages 0 is black and 100 is white

Vectorscope

• Evaluates the chrominance - color quality.

• White is in the center

• Boxes around the scope represent the Primary colors and Complimentary colors

• Used to calibrate color circuits

• Monitor subcarrieer phase

• Noise level

Underscan mode

• Mode on monitor that allows the picture to shrink so that the edges of the signal can be viewed
