Summary  
This chapter covers how to apply and configure modular data‐processing effects with adjustable parameters, control their scope via masking or layering, and chain them to transform media elements.  

General domain of usage  
Video and audio editing

In this chapter we'll take a look at some basic video and audio effects in Premiere Pro.


- **Gaussian blur**: applies a smooth blur without directional bias; useful for soft-focus effects.
- **Directional blur**: blurs the image in a specific direction to simulate motion.
- **Invert**: reverses colors for a negative effect, often used in artistic visuals.
- **Drop shadow**: adds a shadow behind objects or text for better readability.
- **Mirror**: reflects part of an image along an axis for a symmetrical effect.
- **Offset**: shifts the image horizontally or vertically while looping edges.
- **Turbulent displace**: warps the image with fluid distortions, often used for fire, water, or smoke.
- **Warp stabilizer**: reduces camera shake for smoother footage.
- **Black & white**: converts the image to grayscale for a cinematic or vintage look.
- **Ultra key**: a high-quality chroma key effect for removing green screens.
- **Noise**: adds grain or digital noise to simulate vintage film texture.
- **Basic 3d**: rotates and moves a layer in 3d space.
- **Posterize time**: reduces frame rate for a stop-motion-like effect.
- **Transform**: provides advanced control over position, scale, and rotation with motion blur.
- **Horizontal/vertical flip**: flips an image left-right or upside-down.
- **Crop**: trims the edges of a clip and allows custom framing.

Basic video effects

- **Elliptical mask**: applies an effect within a circular or oval area.
- **Polygon mask**: uses four adjustable points for more precise masking.
- **Freehand mask**: allows custom-shaped masks for advanced effects.
- **Feathering**: softens the mask edges for smoother blending.

Masking effects

1. Go to the project panel and click **new item**.
2. Select **adjustment layer**.
3. Drag the adjustment layer onto the timeline above your clips.
4. Apply effects to the adjustment layer to affect all clips below it.

Adjustment layers

- **Pitch shifter**: changes the pitch without affecting speed.
- **High pass filter**: removes low frequencies for a clearer sound.
- **Low pass filter**: removes high frequencies for a muffled effect.
- **Fill left with right**: copies the right channel to the left.
- **Parametric eq**: allows precise control over multiple frequency bands.
- **Studio reverb**: adds natural or artificial echo.
- **Denoise**: reduces background noise like hums and static.
- **Single band compressor**: balances loud and quiet sounds.
