Wave Video Effect

Settings are written to the URL as you change them. Nothing differs from the defaults yet.

Turn a clip into a travelling wave. The step is the same sine displacement the image version uses, run on every frame with a phase that advances with the clip’s time, so crests move across the picture instead of sitting still.

Shape

Amplitude is the peak displacement and wavelength the distance between crests, both as a share of the frame’s shorter side, so the preview at 720p and an export at source size bend identically. Horizontal sways rows, vertical sways columns, both combines them and ripple sends rings out from the centre.

Motion

Speed sets how many cycles pass a point each second. Slow values, around 0.3, read as heat haze or water; 2 and above read as a signal fault. Phase sets where the wave starts at the first frame, which matters when the clip is cut to music or loops.

Because the phase comes from the source timestamp, the live preview and the exported file agree frame for frame, and a clip exported twice bends the same way both times.

Edges

Pixels pulled from beyond the frame repeat the edge, which shows as a smear at high amplitude. Crop the border afterwards with the video cropper, or keep amplitude under about 5% when the edges stay in shot.

Frequently Asked Questions

Every pixel of every frame is read from a position shifted by a sine of its row or column, so straight lines bend into waves. The phase advances with the clip's time, so the wave travels across the picture as the video plays.

Speed is in cycles per second: at 1, each point on the picture passes through one full crest and trough every second. 0 holds the wave still, which turns the effect into a fixed distortion.

It should not. The phase is derived from the source time, which the preview and the export share, so a frame at the same timestamp bends the same way in both.

It is copied into the export unchanged when the container can hold its codec, and re-encoded when it cannot. A note under the export button says which happened.
