Visual and audio effects overview

Descript’s effects come in two kinds: audio effects that clean up and shape sound, and visual effects that enhance or stylize the picture. For step-by-step instructions on adding, adjusting, or removing effects, see Applying and adjusting effects.

How effect order works

Descript processes effects from top to bottom in the order they appear in the Properties panel. This order can affect how your audio or video sounds and looks. For example, placing Reverb before EQ will sound different than placing EQ before Reverb. You can reorder effects anytime by dragging them up or down in the panel.

Note: Effect order only matters for effects stacked on the same layer or region. Effects on different tracks are processed independently.

Visual effects

Visual effects can be applied to individual layers or to entire scenes:

Layer-level effects apply only to the selected layer.
Scene-level effects apply to all visuals within that scene.
Visual effects are scene-specific. If a clip spans multiple scenes, apply the effect to each scene or use the All scenes toggle in the scene editor.

The table below describes each visual effect, including what it does, which settings you can adjust, and where to learn more. For effects with additional options or usage tips, click the Learn more links.

Visual effect	Description	Settings & Parameters	More Info
Ascii	Renders the video as a grid of text characters, brighter areas using sparser characters and darker areas using denser ones.

Portrait Lighting	Keeps the main subject lit while dimming the background, so they stand out in the foreground.	Strength: Overall intensity of the effect Foreground brightness: Brightness applied to the subject Background brightness: Brightness applied to the background	–
Selective color	Keeps a selected color in the video and converts everything else to black and white.	Hue: Color to keep Hue range: Range of hues to preserve Hue feather: Softness of the edge between color and grayscale	–
Shadows	Adds a soft drop shadow behind elements for separation or visual depth.	X / Y: Horizontal and vertical offset Blur: Shadow edge softness Color: Shadow color and opacity	–
Threshold	Converts the image to pure black and white based on brightness for a high-contrast graphic look.	Threshold: Brightness cutoff between black and white Feather: Softness of the transition	–
Uplighting	Automatically brightens the whole video for low-light footage.	Strength: Overall intensity of the brightening Foreground brightness: Brightness applied to the subject Background brightness: Brightness applied to the background	–
VHS	Adds a retro analog-tape look with softening and noise.	Strength: Overall effect strength Softness: Blurriness, simulating reduced bandwidth Color noise: Per-pixel noise and tape grain Sharpening: Enhances edge detail and boosts color saturation, especially on skin tones	–
Vignette	Darkens the edges of the frame to focus attention on the center.	Strength: How dark the edges become Roundness: Vignette shape from oval to circle Center X / Y: Position of the focal point Feather: Softness of the transition	–
Zoom blur	Creates radial motion blur centered around a focal point—adds energy to visuals.	Amount: Blur strength Center X / Y: Origin point for blur	–

Audio effects

Audio effects apply to script layers or sequence tracks and persist across all scenes the layer appears in:

Audio effects can’t be applied to scenes. They must be added to specific media layers or sequence tracks.
To apply effects to a specific voice or recording, use the Sequence Editor.
Studio Sound works differently: it’s applied directly to the original media file and enhances the entire source.

The table below describes each audio effect. For effects with additional options or usage tips, click the Learn more links.

Audio effect	Description	Settings & Parameters	More Info
Studio Sound	AI-powered cleanup for voice; removes noise, echo, and enhances clarity.	Intensity: Controls level of noise suppression	Learn more
Compressor	Reduces volume differences between loud and soft audio.	Presets: Choose from saved configurations Threshold: When compression starts Ratio: How strongly it’s applied Attack: How fast compression engages Release: How fast compression disengages Knee: Smooth vs. sharp transition Input: Visual meter showing input signal level Reduction: Visual meter showing compression amount applied	–
Limiter	Caps volume peaks to prevent distortion—ideal for mastering.	Ceiling: Max volume allowed Threshold: When limiting begins Release: Duration after the spike Input: This shows the input level of your audio before passing through the limiter. Reduction: This shows how much the limiter is reducing your audio’s volume.	–
Lower audio of other layers	Lowers background audio when speech is detected on the script layer.	Amount: How much to reduce other audio	Learn more
Equalizer (EQ)	5-band parametric EQ for precise frequency shaping and tonal control.	Presets: Choose from saved EQ configurations 5 frequency bands: Each with Frequency (Hz), Gain (dB), and Width controls	–

Flanger	Adds a sweeping, jet engine–like motion to audio.	Presets: Choose from flanger presets Mix: Intensity of effect Depth: Delay time modulation depth LFO: Modulation rate in beats Tempo: BPM for tempo sync Mode: Stereo or mono processing	–

Known limitations

A few effect combinations and behaviors are worth knowing about:

Some effects replace everything below them. Effects like Threshold override the layer beneath them rather than blending with it. If you don’t see other effects applying as expected, check whether a replacement-style effect is sitting above them in the stack.
Ascii combined with Shadows can look broken. This is a known rendering interaction. Apply one or the other for the cleanest result.
Stacking Portrait Lighting and Uplighting can produce uneven results. Combining them can look unnatural. Try one at a time and adjust the strength before reaching for the other.
