The prompt
Seamless 6-second looping animation, 1920x1080, 30 fps, no camera movement, no text. Scene: six soft, glossy liquid blobs drift slowly across a flat warm cream background (#f6f1e7) with a very faint warm vignette. The blobs behave like metaballs: when two come close they stretch toward each other, neck together and merge into one smooth shape, then pull apart again. Edges are soft but clearly defined, like thick syrup or gel, not blurry clouds. Colors (pastel, one per blob, blending smoothly where they merge): peach #ff9a76, lilac #b8a1ff, butter yellow #ffd166, mint #7ed3b2, coral #ff6b6b, sky blue #8ecbff. Lighting: soft key light from the top left. Each blob reads as a rounded 3D dome with gentle diffuse shading, a small bright specular highlight toward the upper left and a broader soft sheen. A faint warm brown contact shadow sits slightly below the shapes, as if they float a few millimeters above paper. Motion: slow, calm and hypnotic. Each blob follows a smooth Lissajous-style path (one or two full cycles per loop) and gently breathes in size by about ±8%. Nothing moves fast; no flicker. The last frame must flow perfectly into the first so the clip loops forever without a visible cut. Finish: a very subtle static film grain over everything. Mood: calm, tactile, modern, like a premium app background.
Tip: The prompt above is written for an AI video tool (Kling, Runway, Veo and similar). This exact version was rendered frame by frame from the canvas code included in the download (source/liquid-blob-loop.html): every motion term is a sine with a whole number of cycles per 6 seconds, which is what makes the loop mathematically seamless. AI video tools rarely loop perfectly on their own; ask for a 'seamless loop' and crossfade the last 0.5 s into the start if needed.
