ComfyUI Temporal Mask Tools
Temporal-mask cleaning tools for ComfyUI: union noisy frames to smooth flicker, then drop one-off specks so your mask sequences stay stable.

Nodes
Temporal Mask Union (TemporalMaskUnion)
Combines nearby frames in a temporal mask sequence to suppress flicker.
| Input | Type | Default | Notes |
| --- | --- | --- | --- |
| mask_batch | MASK | required | Accepts (frames, H, W), (batch, frames, H, W), or (H, W) tensors. |
| radius | INT | 2 | Temporal half-window size. |
| mode | STRING | "or" | "or" keeps any active frame, "majority" uses the threshold. |
| threshold | INT | 3 | Minimum active frames within the window when mode="majority". |
Temporal Mask Remove Short Objects (TemporalMaskRemoveShortObjects)
Drops one-frame flicker or tiny specks by combining per-frame connected-component filtering with temporal run-length pruning.
| Input | Type | Default | Notes |
| --- | --- | --- | --- |
| mask_batch | MASK | required | Supports (H, W), (frames, H, W), (batch, frames, H, W) tensors. |
| min_duration | INT | 2 | Minimum consecutive frames required to keep a pixel active. |
| min_area_pixels | INT | 10 | Connected components smaller than this pixel count are removed. |
Usage
- Clone into
ComfyUI/custom_nodesand restart ComfyUI. - Drop the desired node into your graph and connect it to a mask sequence batch.
- Optional: enable node-level
debug_output(when available) while tuning parameters.
