What this node does

Glitch FX damages a COMFYTV_VIDEO clip on purpose with horizontal block displacement and chromatic (RGB) channel offsets, then writes a new snapshot on ▶ Run. The corruption is randomized per frame from a seed, so the result is repeatable. In and out are both COMFYTV_VIDEO. To feed native ComfyUI nodes, insert a Bridge — see the bridge guide.

​
When to use it

  • Fake a corrupted-signal / broken-transmission look for a transition or accent.
  • Add VHS/datamosh grunge to a music-video or title card.
  • Punch up a beat drop with an occasional torn-frame flash (low chance).

​
Parameters

​
chance

Probability that a given frame gets glitched, 0.0–1.0, default 0.5. At 0 the node passes the clip through untouched (identity). Lower for rare, punctuated glitches; 1.0 glitches every frame.

​
block_h

Glitch block height as a fraction of the frame, 0.01–1.0, default 0.2. Smaller = thin torn slivers; larger = big displaced bands.

​
shift

Horizontal displacement amount, 0.01–1.0, default 0.2. How far glitched blocks slide sideways.

​
color_intensity

RGB channel-split strength, 0–4, default 3. 0 = no chromatic separation; higher pulls the red/green/blue channels further apart.

​
seed

Random seed, 0–99999, default 7. Same seed = same glitch pattern; change it to reroll.

Tips

  • Set chance to 0 to A/B against the untouched clip without unwiring.
  • Keep chance low and shift high for sparse but violent hits; keep chance high and shift low for a constant shimmer.
  • Strobe — flash/hold frames on an interval for a different kind of jolt.
  • Art FX — stylized looks instead of digital damage.
