What this node does

Video Transition crossfades video_a into video_b using ffmpeg’s xfade transitions. Pick from a large menu of named transitions (plain fade, dissolve, directional wipes and slides, circle/rect reveals, radial, pixelize, and more), set how long the transition lasts, and optionally where in clip A it begins. It runs on ▶ Run. Both video_a and video_b are required COMFYTV_VIDEO inputs — the node errors if either is missing. Output is a single COMFYTV_VIDEO. To hand the result to a native ComfyUI node, insert a Bridge (ComfyTV/Bridge). See https://github.com/jtydhr88/ComfyTV/blob/main/docs/bridges.md.

​
When to use it

  • Put a clean fade or dissolve between two shots.
  • Use a directional slide/wipe to move from scene to scene.
  • Add a stylized reveal (circle open/close, radial, pixelize) between clips.

​
Parameters

​
transition

The xfade transition style. Options (from XFADE_TRANSITIONS): fade, dissolve, fadeblack, fadewhite, fadegrays, fadefast, fadeslow, wipeleft, wiperight, wipeup, wipedown, wipetl, wipetr, wipebl, wipebr, slideleft, slideright, slideup, slidedown, smoothleft, smoothright, smoothup, smoothdown, circlecrop, rectcrop, circleopen, circleclose, vertopen, vertclose, horzopen, horzclose, diagtl, diagtr, diagbl, diagbr, hlslice, hrslice, vuslice, vdslice, hlwind, hrwind, vuwind, vdwind, coverleft, coverright, coverup, coverdown, revealleft, revealright, revealup, revealdown, squeezeh, squeezev, zoomin, distance, pixelize, radial, hblur. Default fade.

​
duration

Transition length in seconds, 0.1–5.0, step 0.05, default 1.0.

​
offset

Seconds into clip A where the transition starts, 0.0–3600.0, default 0.0 (auto — the transition ends clip A, so it begins duration before A’s end).

​
video_a / video_b (inputs)

The outgoing (video_a) and incoming (video_b) COMFYTV_VIDEO clips. Both required.

Outputs

​
Tips

  • Leave offset at 0 for the usual behavior — the transition auto-places at the tail of clip A. Set it only when you need the transition to start earlier inside A.
  • For a grayscale-pattern (gradient) wipe or your own custom shape, use Luma Wipe instead.
  • Luma Wipe — pattern/gradient-driven wipes and custom-image transitions.
  • Sequence — assemble several clips with per-cut transitions in one node.
