Random Bars랜덤 바 와이프

Parallel bars disappear in a varying order as progress advances.

The frame breaks into blocks that disappear at different times. It combines a regular grid with a scattered dissolve.

`progress` defaults to 0.5 and ranges from 0 to 1. `blockSize` defaults to 0.08 and ranges from 0.01 to 0.5 for block size; `softness` defaults to 0.15 and ranges from 0 to 1 for fade softness. `invert` defaults to false and reverses the order.

Put the incoming scene below the outgoing image and animate progress to make a transition. Large blocks feel coarse and small ones create a dense pattern, so match the size to the image. Small text can break along the block edges.

When to use

Use it for grid-like dissolves, pixel-flavored scene changes, or video effects aligned with block graphics. Avoid it when small type or fine UI detail must be preserved.
