To apply Lighting Effects textures
A bump layer in the Lighting Effects lets you use the pattern or texture from a clip to control how light reflects off
an image. Using a clip with textures like paper or water can create a 3D-like lighting effect.
1
Add the clip you want to use as a bump layer (texture) to a separate track in your sequence.
2
Click the Toggle Track Output icon
to hide the track containing bump layer clip.
3
Add the Lighting Effects to a clip in the same sequence.
4
In the Effect Controls panel, click the triangle to expand the Lighting Effects.
5
(Optional) Click the triangle next to Light 1 to adjust the light’s properties.
6
Choose the video track containing the bump layer from the Bump Layer menu.
7
From the Bump Channel menu, specify whether to use the bump layer clip’s red, green, blue, or alpha channel to
create the lighting effects texture.
8
Select the White Is High option to raise the white parts of the channel from the surface. Deselect this option to
raise the dark parts.
9
Scrub the underlined text to specify the Bump Height value from flat (0) to mountainous (100).
Vectorscope and waveform monitors
About the vectorscope and waveform monitors
Adobe Premiere Pro has a
vectorscope
and
waveform monitors
(YC Waveform, YCbCr Parade, and RGB Parade) to
help you output a video program that meets broadcast standards and also assist you in making adjustments based on
aesthetic considerations, such as color corrections.
For decades, video production and duplication facilities have used
waveform monitors
and
vectorscopes
to accurately
evaluate video
levels
—specifically, color and brightness.
A vectorscope measures the
chrominance
(color components) of a video signal, including
hue
and
saturation
. A
vectorscope maps a video’s color information onto a circular chart.
The traditional waveform monitor is useful in measuring the brightness, or
luminance
component, of a video signal.
In Adobe Premiere Pro, the waveform monitors can also display chrominance information. The waveform monitor
works something like a graph. The horizontal axis of the graph corresponds to the video image from left to right.
Vertically, the waveform displays the luminance or chrominance levels.
