Seam melt guide

Start

The tool opens with two sample pictures, A and B, and the Subject survives preset, protecting the centre of the picture. The picture fills the frame; the panel sits beside it.

What you need

• A current browser with WebGL. Chrome, Edge, Firefox and Safari all have it.
• Two pictures of your own, if you want them. Any image the browser can open works; the samples are there until you swap them.

Your first result

1. Open Seam melt and tap the part of the picture that should survive. A run starts: A narrows, then B widens. See tap origin.
2. When the run ends, press Replay at the top of the panel. This run protects the spot you tapped, and goes from B back into A.
3. Press a preset under Presets, such as Squeeze cut, then Replay again.
4. At the top of the panel, press the Image A and Image B tiles to pick your own two pictures, or drop two at once.
5. Press Save PNG for a still, or Record video to keep one full run.

Good to know

• A tap moves the protected spot, but the run it starts still uses the old spot; the new one counts from the next run. A tap during a run does nothing.
• Moving any slider takes the highlight off the preset, and the next run uses your settings.
• The frame takes the shape of picture A. Picture B is stretched to that shape, so two pictures of the same shape look best.
• On a phone the controls sit in a bar at the bottom of the screen. Tap the bar to open them.
