Silk hero background loop

How it was made

FrameCall's Quality model made this video from one prompt, in one run, with no hand edits. The prompt, word for word:

A 20-second looping hero background for the homepage of Tidewell, a studio that makes sleep and breathing apps, with our headline sitting over it. The background is flowing silk: big translucent folds of fabric in deep indigo and dusk blue with a little peach light, rippling slowly as if a breeze moves under them, light catching the crests and soft shadow in the troughs. Let the motion evolve through the loop: for a while the folds gather and lift, then they settle and slide sideways, then a slow wave rolls through them from left to right, and by the end everything is back exactly where it started so the loop never shows a join. Tiny dust motes drift through the light. The headline 'Breathe out. We'll take it from here.' sits left of centre in a calm, elegant serif, perfectly still for the whole loop, with a small line 'Sleep and breathing, made gentle' under it. Keep the area behind the words the calmest, darkest part of the silk so they always read, and let the bigger movement happen on the right and around the edges. No buttons, no logo in the corners, no glow.
