Looping promo: from prompt to glass knot

Make a seamlessly looping horizontal video, 1920×1080, 8 seconds, no sound, for a small card on a website: the text is huge, bold and readable, with one bright thing on screen at a time. Keep the text away from the side edges and the top left corner. Palette: almost black background, cold white light, rainbow facets on the glass and a hot point at the end. Light bloom, film grain, light motion blur on the jerks. 0–2 s: a quiet dark screen, a cursor blinks, the phrase "Love these prompts?" (replace with your own) is typed out like a prompt. At about 2.2 s the letters scatter into glowing dots, and they fly together into a crystal glass torus knot with rainbow edges. At about 3 s — one powerful hit: a shockwave, a white flash, a sharp camera push-in on the knot. From 3.5 s the kinetic text "Just try it!" (replace with your own) flies in large, the knot behind it is muted and moves back slightly so the text stays readable. At 5 s the knot collapses into a spark, a frame of glowing lines is drawn from it, and the text "No setup" (replace with your own) breaks through it, and the frame bursts into shards. In the last seconds everything is pulled into one red-hot point, from which the picture returns to the dark beginning, so the loop closes without a seam.
