Screen Melt: How to Create the Glitch in After EffectsScreen melt is a visually striking glitch effect where parts of an image or video appear to “melt,” smear, or drip downward while colors separate, scanlines shift, and digital artifacts ripple across the frame. It’s widely used in music videos, film transitions, motion-graphics stings, and social-media clips to signal distortion, memory corruption, or an unsettling break from reality. This tutorial explains multiple approaches to creating convincing screen-melt effects in Adobe After Effects, from quick presets to fully customizable procedural builds.

Overview and creative uses

Screen melt can vary from subtle pixel-stretching to dramatic liquefaction. Common characteristics:

  • Vertical smear/drip — pixels stretch downward, often at varying speeds.
  • Chromatic separation — RGB channels shift independently.
  • Noise and artifacts — scanlines, TV-noise, jitter, or displaced blocks.
  • Edge tearing and displacement — portions of the image tear away or shift horizontally.
  • Animated masks and reveals — using mattes to control where melt occurs.

Use cases:

  • Transition between scenes (melting out of one shot into another).
  • Emphasizing a memory, dream, or digital corruption in narrative work.
  • Background texture for titles, logos, or music-visual clips.
  • Stylized design for social content and promos.

Project setup and tips

  • Composition settings: match your footage resolution and frame rate. Typical projects use 1920×1080 or 4K at 24/30/60 fps depending on output.
  • Precompose footage: keep the original safe and apply effects to a precomp for non-destructive workflows.
  • Color management: work in linear color if heavy grading will follow; otherwise, standard 8-bit/16-bit is fine for stylistic melt effects.
  • Render performance: many displacement/noise operations are GPU/CPU heavy—use proxies or lower-res previews during iteration.

Method 1 — Fast, plugin-free “Stretch & Displace” (good for quick edits)

This method uses native After Effects effects (Turbulent Displace, Displacement Map, CC Smear) and is fast to set up.

  1. Import footage and precompose it (Layer > Pre-compose > Move all attributes).
  2. Duplicate the precomp twice (you’ll have three layers: Base, Melt-1, Melt-2).
  3. On Melt-1:
    • Apply Effect > Simulation > Turbulent Displace.
      • Amount: 10–50 (adjust to taste)
      • Size: 30–200
      • Complexity: 2–4
      • Evolution: animate over time (keyframe or expression: time*100)
    • Apply Effect > Distort > Displacement Map.
      • Use Channel: Luminance (or Red for channel separation variants).
      • Max Horizontal Displacement: 0
      • Max Vertical Displacement: 50–300 (increase for stronger melt)
      • Choose Melt-1 itself or a generated gradient as the displacement layer.
  4. On Melt-2:
    • Apply Effect > Stylize > CC Smear.
      • Mode: Linear Smear
      • Start & End points: animate to create dragging motion.
    • Optionally add a directional blur (Effect > Blur & Sharpen > Directional Blur) with the same motion angle.
  5. Blend modes & masks:
    • Set Melt-1 and Melt-2 to Add, Screen, or Overlay, and animate their opacity to fade in/out.
    • Use animated luma mattes or masks to localize the melt to areas you want (e.g., top-down gradient mask where white = melted).
  6. Chromatic separation:
    • Precompose a copy, then apply Effect > Channel > Shift Channels.
    • Set Take Red From: Red, Take Green From: Full Off, Take Blue From: Full Off (for isolated red).
    • Offset the red precomp slightly horizontally or vertically (position keyframes or use a time-displacement).
    • Repeat for green and blue layers, offsetting each layer differently and using Blend Modes Lighten/Add.
  7. Final touches:
    • Add noise (Effect > Noise & Grain > Add Grain) and scanlines (created with a textured solid plus blending mode).
    • Apply a vignette and slight chromatic aberration using Optics Compensation or Lens Distortion.

Tips: Use Adjustment Layers with Curves or Levels to push contrast before displacement for stronger luminance-based displacement.

Method 2 — Procedural approach with displacement maps and animated mattes (more control)

This approach gives refined control over where and how melt happens using generated displacement maps and animated mattes.

  1. Create a new comp (same size as footage) called “Melt Map.”
  2. Add a black Solid. Add Effect > Noise & Grain > Fractal Noise.
    • Fractal Type: Dynamic or Max
    • Contrast: 200–400
    • Scale: 50–300
    • Complexity: 4–6
    • Animate Evolution (time*X) to create movement.
  3. Add Effect > Color Correction > Levels to increase contrast (this sharpens the melt areas).
  4. Use Effect > Generate > Ramp (or Gradient Ramp) on a duplicated solid to create a vertical black-to-white gradient, then precompose and apply Fast Blur or Gaussian Blur to soften edges — this gradient controls vertical falloff of the melt.
  5. Combine Fractal Noise and Gradient:
    • Place both in a precomp and set the blending mode of the fractal to Add or Overlay over the gradient to get a textured matte with vertical bias.
  6. Go to your footage precomp and add Effect > Distort > Displacement Map.
    • Set Displacement Map Layer to the Melt Map precomp.
    • Vertical displacement: high positive (100–600) depending on desired intensity.
    • Horizontal displacement: small or zero.
    • Use Luminance for displacement channels.
  7. Use the same Melt Map as a Track Matte:
    • Duplicate the footage layer.
    • On the duplicate, set Track Matte to Luma Matte using the Melt Map precomp (or use Set Matte effect).
    • Animate the Melt Map or keyframe its position to crawl downward — this makes the melt reveal travel from top to bottom.
  8. Add edge tearing:
    • Precomp the displaced layer, then animate horizontal shifts with the “Turbulent Displace” or “Displacement Map” using a second displacement map (lower frequency) to create torn segments.
  9. Color & noise:
    • Add the chromatic separation technique described in Method 1.
    • Apply a subtle Film Grain or Add Grain effect for organic texture.

Advantages: Procedural maps let you precisely animate where melting occurs and reuse the Melt Map for multiple layers.

Method 3 — Advanced look using 3rd-party plugins (Sapphire, Red Giant, RE:Vision)

If you have plugins like Sapphire, Red Giant Universe, or RE:Vision Twixtor/RE:Flex, you can achieve faster and higher-quality melts.

  • Sapphire’s “S_Melt” or similar glows and displacements provide one-click results with deep parameter control.
  • Red Giant Universe has “Chromatic Aberration,” “VHS,” and displacement effects that combine well for stylized glitch.
  • RE:Vision’s RE:Flex and RE:Map can give organic morphing and remapping for liquid-like melts.
  • Using Optical Flares or Lenscare for added depth and focus-shift during melt helps sell realism.

Plugins speed iteration and often include GPU acceleration.

Making the melt feel organic — animation tips

  • Stagger movement: vary the melt speed across horizontal bands; use noise to modulate speed.
  • Ease keyframes: use Easy Ease and the Graph Editor to avoid linear, mechanical motion.
  • Add secondary motion: small horizontal slides, jitter, or bounce-back on the top edges.
  • Animate mask feathering: change mask feather to soften the melt edges over time.
  • Layer timing: offset duplicated melt layers slightly to simulate multiple passes of distortion.
  • Sound-sync: use audio amplitude to drive evolution or displacement intensity for rhythm-synced melts (Effect > Expression Controls > Slider Control, link to Audio Amplitude).

Example expression to modulate displacement with a slider named “Melt Strength”:

// Apply on Displacement Map's Max Vertical Displacement melt = effect("Melt Strength")("Slider"); value * (melt/100)

Chromatic separation and analog artifacts

Chromatic separation makes digital melting feel more electronic and glitchy.

Quick method:

  • Precompose the footage three times.
  • On each precomp, use Effect > Channel > Shift Channels to isolate R, G, B (set other channels to Full Off).
  • Nudge position/rotation/scale slightly for each channel and set Blending Mode to Screen or Add.
  • Add subtle noise and horizontal scanlines (create with a patterned solid and Motion Tile to repeat lines).

Analog artifacts:

  • Use displacement maps with high-frequency fractal noise to create pixel blockiness.
  • Add Effect > Stylize > Find Edges (blended at low opacity) for a brittle digital look.
  • Use Tint or CC Toner for color grading toward VHS palettes.

Example step-by-step: dramatic melt reveal (beginner-friendly)

  1. Import footage, create comp, precompose footage as “Shot Precomp.”
  2. Duplicate Shot Precomp twice (Shot A, Shot B).
  3. On Shot B, apply Fractal Noise (low contrast) to create movement; precompose as Melt Map.
  4. On Shot A:
    • Apply Displacement Map using Melt Map; Max Vertical = 250.
    • Set Displacement Map to use Luminance.
  5. On Shot B:
    • Use Shift Channels to isolate red; move X position +6px.
    • Duplicate again for green (-6px) and blue (0px), adjusting offsets.
  6. Above all layers add a new solid with a vertical gradient ramp, animate its position downward to reveal the displaced Shot A through a luma track matte.
  7. Add Add Grain, a vignette, and a mild Camera Lens Blur to the top layer for polish.

Performance and rendering advice

  • Pre-render heavy displacement or precomps when satisfied.
  • Use RAM Preview with lower resolution for iteration.
  • For final renders, choose an appropriate codec: ProRes or CineForm for high-quality masters, H.264/H.265 for web delivery.
  • If using expressions on many layers, consider converting complex driven parameters to keyframes before final render.

Troubleshooting common issues

  • Jittery melt: reduce displacement map animation frequency or apply motion blur (Layer > Switches > Motion Blur).
  • Banding in gradients: increase color bit depth (Project Settings) and add tiny noise to gradients.
  • Slow previews: use proxies, lower comp resolution, or pre-render Melt Map.
  • Visible seams at edges: increase displacement blur or feather masks to soften transitions.

Variation ideas and creative prompts

  • Combine with 3D camera moves: precompose melt elements and use as 3D layers to integrate with parallax.
  • Use particle systems (CC Particle World or Particular) to make droplets fall from melted areas.
  • Reverse the melt to “freeze” into place for a surreal rewind effect.
  • Use selective melt: only melt faces, text, or logos for narrative emphasis.
  • After Effects’ official documentation for each native effect (Displacement Map, Turbulent Displace, Fractal Noise).
  • Tutorial channels and courses focusing on glitch and VFX workflows (use your preferred learning platform).
  • Plugin docs for Sapphire/Red Giant for one-click advanced looks.

Screen melt is a versatile effect that sits between digital glitch and organic liquefaction. Start simple with native tools, then layer chromatic separation, noise, and procedural displacement maps for more sophisticated results. If you tell me your After Effects version and whether you have plugins (Sapphire, Red Giant, Trapcode), I can give a tailored step-by-step project file with exact settings.
