ANR Wave Bend

Overview

Wave Bend shifts the image back and forth in a regular wave. The wave travels in the Direction you set and pushes pixels at right angles to it: at 0 it runs across the frame and bends the image up and down, like a flag.

Amplitude is how far pixels move and Wavelength the distance between peaks, both in pixels. Speed moves the wave by itself, in waves per second; Phase shifts it by hand. Profile changes the shape of the wave: a smooth sine, a zigzag triangle, or a square wave that cuts the image into offset bands.

Use it for waving flags and banners, underwater and dream wobbles, retro and glitch slices, and title animations.

Inputs

1. Sourcerequired

   The image to bend.

2. Maskoptional

   Limits the effect: where its alpha is black, Source passes through unchanged.

Output. The bent Source, premultiplied and covering the project format. What fills the edges, where pixels are pulled in from outside the image, follows Outside Source.

Quick start

1. Add ANR Wave Bend after the image.
2. Set Amplitude (how far pixels move) and Wavelength (the distance between peaks).
3. Set Direction: 0 sends the wave to the right and bends the image up and down; 90 sends it upward and bends the image sideways.
4. Set Frames per Second to your project's frame rate. Speed sets how many waves pass per second: 0 holds the wave still, negative values reverse it.
5. Choose the Profile: type 0 for a sine, 1 for a triangle, 2 for a square wave.
6. Keep Outside Source at 1 (or 2) on full-frame plates; 0 leaves transparent gaps at the edges.

Tips

• Key Amplitude from 0 up and back to 0 for a wobble transition, or for a hit on a beat.
• Profile 2 with a short Wavelength and Direction at 90 slices the image into bands shifted left and right, for a quick glitch look.
• Stack two Wave Bends at different directions and wavelengths for a looser, water-like wobble.
• Animate Phase instead of Speed when the wave must reach exact positions on given frames.
• For a weaker bend, lower Amplitude rather than Mix: Mix fades between the bent and the original image, which can look doubled.

Good to know

• The result always covers the project format: anything outside it, such as overscan, is cut off.

ANR Noise WarpWarps the image with smooth, animated noise: heat haze, underwater wobble, dreamy distortions and liquid transitions.ANR Ripple TankWater ripples from one or two drops that spread, bounce off the frame edges and fade, as a height map or as a ripple distortion of your image.ANR Elastic RevealA transition from one image to the next through a rubbery ripple and turn, for dreamy, wobbly or psychedelic cuts between shots or titles.
