OmniFade - Frei0r Transition Plugin for Kdenlive

A versatile cross‑fade transition for Kdenlive.

Features

• Fade Progress (position) – standard transition progress, animated from 0 to 1.
• Speed Curve (%) – applies a power‑law easing curve to the fade timing. Higher values create stronger acceleration/deceleration.
• Gentle Arrival (%) – adds a smooth slowdown at the end of the transition.
  • When Speed Curve is 0%, it acts as a reverse ease‑out (fast start, slow end).
  • When Speed Curve is used, it creates a deceleration zone near the end – the fade eases into the final frame.
• Independent Zoom per Clip – choose separate behaviours for the outgoing and incoming clips:
  • Expand – clip grows larger over the transition.
  • Static – no zoom (scale = 1).
  • Shrink – clip shrinks over the transition.
  • Zoom Strength (%) – controls how intense the zoom effect is.
• Blur Strength – radial blur that automatically adjusts its amount based on speed.
• Fill Background (average) – fills the empty background with the average colour of each clip.
• Invert – swaps the incoming and outgoing clips.
