Video editing stages

​
Video editing (ComfyTV / Video)

Feed a video (from a Generate → Video stage or a Load Video node) into any of these:
  • Clip / Split / Concat — trim to a range, cut at a timestamp (two outputs), join clips.
  • Crop / Resize / Rotate / Speed — region crop, resolution change, 90°-step rotation, variable speed and reverse.
  • Extract Frame / Extract Frames — pull a single still, or mark timestamps on the timeline and export them as a set.
  • Scene Detect — find cuts, preview each scene, and split precisely at a detected boundary.
  • Make Proxy — generate a lightweight proxy; players transparently switch to it for smooth scrubbing on heavy footage.
  • Volume / Mux Audio / Demux — fade in/out, replace or add an audio track, or split a clip into its audio track and silent video (the 🔀 Demux toolbar action spawns both at once).
  • ↪ Extend (toolbar action) — one-click chain: extract the source’s last frame, spawn a new Video Stage, wire that frame as the I2V starting image.
Keyboard on the timeline widgets (Clip, Split, Extract Frames, and friends): after clicking a track, ← / → nudge the active handle by exactly one frame, Home / End jump it to the first / last frame — frame-accurate cuts without pixel-hunting. Numeric sliders across the suites also accept typed values: click the number, type, and it clamps to the legal range. Still pending backend wiring: Video Upscale and Subtitle Erase (Smart / Region) — see roadmap.md.

​
Color (ComfyTV / VideoFX)

Color wheels with lift-gamma-gain (Video Color), Curves, LUT (live preview; LUT files come from the resource library), ASC CDL, HueCorrect, Selective Color, Histogram EQ, Gray World white balance.

​
Keying & matte (ComfyTV / Keying)

Keying bench A full keyer bench modeled on pro compositors: Chroma Key, PIK (image-based keyer), Keyer, Despill, Color Suppress, Select0r, KeyMix, Matte Monitor, and Matte Morphology for growing / shrinking / feathering mattes.

​
Roto, tracking & paint

Roto Mask (bezier shapes with feather, keyframable), Shape Mask, Motion Track (point tracking that can drive transforms or corner pins), Mask Propagate (optical-flow tracking of a mask across frames), Paint Strokes (paint / clone brushes over time), Face Blur and Spot Remover.

​
Compositing & transitions (ComfyTV / Compose)

Video Composite (39 blend modes, opacity, masks), Video Transform and Corner Pin (keyframable), Video Transition (57 xfade families), Luma Wipe (gradient-image wipes), Time Remap (speed curves), Sequence (assemble clips on a track).

​
Effects (ComfyTV / VideoFX)

Light & optics: Glow, God Rays, Lens Distort (multiple lens models), Chromatic Aberration, Lens Flare, Z-Defocus. Texture & era: Old Film, Regrain, Frame Blend, Posterize, Pseudocolor, Chroma Shift. Art & warp: Particles, Glitch FX, Art FX, Kaleidoscope, Wave Warp, Water, Light Graffiti, Slit Scan, Feedback FX, Strobe, Stylize, Ken Burns. 360 & projection: 360 Projection, 360 Stabilize, Card 3D, UV Remap (STMap) + STMap Generate. Enhance: Denoise, Blur / Sharpen, Deinterlace, Frame Interpolate, Stabilize / Stabilize Pro.

​
Text, analysis & infrastructure

  • Title / Subtitles / Annotate — text overlays, subtitle tracks, and review annotations (boxes, arrows, grids).
  • Subtitles · Speech-to-Text — generate a subtitle track from the audio.
  • Video Scopes — waveform / vectorscope / histogram / RGB parade for QC.
  • Expression — drive any numeric parameter with a math expression.
  • FX Chain — stack many FX nodes and render the whole chain in a single pass, with a live preview of the combined result.
FX Chain

​
Audio (ComfyTV / Audio · AudioFX)

Audio suite
  • Stem Split — separates a track into vocals / accompaniment / drums / bass / other. Built in, nothing extra to install; works on audio or the audio of a video.
  • Dynamics (compressor, gate, limiter, de-esser), EQ (parametric, with a graph UI), Loudness (LUFS normalization).
  • Denoise / Noise Reduction (Spectral) / Repair — broadband and spectral-gate denoising, click and artifact repair.
  • Time / Pitch — time-stretch and pitch-shift; Saturate, Echo, Modulation (tremolo / flanger / …), Stereo tools.
  • Reverb — Audio Convolve (IR) for convolution reverb, with Audio Sweep + Audio Deconvolve to capture the sound of a real room and reuse it; Muse Reverb for algorithmic reverb.
  • Mix / Crossfade / Duck — multi-track mixing, crossfades, sidechain ducking under a voice track.
  • Beats & Notes — detects the beat grid and the individual notes in a track; Analyze and Visualize for inspection; Split Export for segment slicing.
  • Audio Reactive + Audio Meter Overlay — turn the audio’s envelope into parameter automation for video FX, and burn level meters into the picture.
A separated / extracted audio track can be wired into a Video Stage’s optional audio input for audio-driven video (works with LTX 2.3 IA2V). For music composition (scores, piano rolls, SoundFont synthesis), see making-music.md.
