Frame Pipeline

Frames pass through stateless glitch ops, optional temporal mosh, and WebGL shader passes.

• Stateless: JPEG‑style corruption, RGB shifts, pixelation, scanlines.
• Temporal: motion vectors, smear/blend, frame skipping/stepping.
• WebGL: shader‑based distortions and post‑FX.

Determinism is opt‑in; turn it on when you need reproducible artifacts.

Key Parameters

Effects Catalog (Current)

These are the effects currently implemented in the engine. All are available in the UI unless noted.

Core / Compression

• Corruption: amount, quality, iterations, seed
• Corrupt Mode: safe / unsafe byte corruption

Destruction

• Melt
• Shred
• Scatter
• Burn (heat tint / blend influence)
• Shake (frame jitter)

Color & RGB

• Brightness
• RGB Shift
• Color Offset
• Channel Offsets: red / green / blue shift
• Pixelation

Display / Texture

• CRT Scanlines + intensity
• Noise (digital slivers)

Analog Sync Distortion

• Phase Slip: phaseSpeed, phaseOffset, phaseJitter, wrapMode, banding
• Analog Inertia: analogInertia (Verlet-style damping)
• Horizontal Drift: hOffset, hSpeed, hAmount
• Wave Distortion: waveAmount, waveFrequency, waveSpeed, wavePhase
• Vertical Sync Collapse: bandCount, baseSpeed, bandVariance, jitter, wrapMode
• VHS Tracking Band: strength, bandHeight, speed, position, tear

Additional Analog Layers

Professional Glitch

• Pixel Sorting: brightness / hue / random
• Channel Separation

Temporal

• Temporal Echo
• Time Smear
• Reverse Burst
• Stutter Lock
• Temporal Displace
• Partial Replace (patterns + offset)
• Chaos (seed evolution)

2D Datamosh (Canvas)

• I-Frame / GOP: interval, bloom, soft reset
• Motion Vector Field: flowX/flowY/rotate/zoom
• Feedback
• Macroblocks: blockList, blockSize
• Ref Swap + Motion Residue
• MV Abuse (block match)
• History Capture Interval

WebGL Mosh (Shader)

• Motion Sculpture WebGL (when moshMode = webgl)
• Shader Mosh: feedback, decay, warp, block size, RGB offset
• Displacement: strength, scale, speed, quantize

Audio Reactive

• Audio Modulation: RGB shift, amount, warp, feedback, blocks, melt, shake, noise
• Audio Events: freeze, reverse burst, swap, noise hit, sync kick

Strict Effects Layer (Optional)

• Invert (debug layer)
• Scanlines (bound to scanline intensity)

Temporal Mosh

• masterSpeed: slow down or overcrank the feed.
• blend/smear: streaks and trails via accumulative mixing.
• frameOps: drops, holds, and reverse micro‑loops.
