ComfyUI Camera Shake Node

A ComfyUI custom node that applies subtle, handheld-style camera shake to an image batch. It adds per-frame affine transforms (translate, rotate, scale) to simulate natural micro-movement, ideal for adding life to video/animation frame sequences.

Node

Batch Camera Shake (Subtle) — category: image/transform

Applies smoothed, seedable per-frame motion to an IMAGE batch ([B, H, W, C]).

Inputs

| Input | Type | Default | Description | |-------|------|---------|-------------| | images | IMAGE | — | Input image batch to apply the shake effect to | | seed | INT | 0 | Random seed for reproducible shake patterns | | translate_px | FLOAT | 2.0 | Max horizontal/vertical movement in pixels | | rotate_deg | FLOAT | 0.15 | Max rotation angle in degrees | | scale_pct | FLOAT | 0.5 | Max zoom variation as a percentage | | freq | FLOAT | 1.0 | Shake frequency multiplier (higher = faster changes) | | smoothing | FLOAT | 0.85 | Motion smoothness (higher = floatier, lower = jittery) | | distribution | choice | even | Intensity curve over time: even, center, ramp_up, ramp_down, ease_in, ease_out, ease_in_out | | min_intensity | FLOAT | 0.5 | Minimum intensity as a fraction of max (ignored when distribution is even) | | border | choice | reflect | Edge handling: reflect, replicate, or zeros |

Output

| Output | Type | Description | |--------|------|-------------| | IMAGE | IMAGE | The shaken image batch |

Installation
