Switching Basics

Video switching is the core of live production — selecting which source your audience sees and transitioning between them smoothly.

The preview/program workflow

pMix uses a preview/program model:

  1. Tap a source in the grid to load it into preview (yellow border)
  2. Tap the transition button to move it to program (green border)

The audience only sees what’s on program. Preview is your private staging area.

Transition types

pMix includes 11 transition types:

Transition Description
Cut Instant switch, no animation
Cross Dissolve Smooth blend between sources
Fade Fade through a solid color (black, white, gray, blue, red, or green)
Wipe Edge wipe from one side
Iris Circular reveal from center or edges
Star Wipe Five-pointed star shape reveal
Split Split screen reveal
Cover New source slides over the old one
Cross Zoom Zoom blur transition
Cube 3D cube rotation
Twist 3D twist rotation

Each transition (except cut) supports configurable duration, direction (left, right, up, down where applicable), and easing (linear, ease-in, ease-out, ease-in-out).

Quick actions

  • Tap a source → set as preview
  • Tap the transition button → execute the configured transition (preview → program)
  • Double-tap a source → instant cut to program (bypasses preview)
  • Long-press the transition button → choose a different transition type from the quick menu

Configuring transitions

Open the Transitions panel to set:

  • Type — Select from the 11 transition types
  • Duration — How long the transition takes (0.5–3 seconds typical)
  • Direction — Which direction the transition moves (for wipe, cover, split, etc.)
  • Easing — The acceleration curve of the animation

The configured transition is used whenever you tap the transition button.

Gamepad support

If a gamepad is connected:

  • D-pad — Navigate between sources
  • A button — Set source as preview
  • B button — Execute the configured transition

OSC control

Transitions can be triggered and configured via OSC. See OSC Remote Control for the full address space.

Key OSC commands:

  • /pmix/cut — Instant cut
  • /pmix/auto — Execute configured transition
  • /pmix/preview/{n} — Set slot n as preview
  • /pmix/program/{n} — Set slot n as program
