Skater lands and catches the board

H3 Max continues the rooftop kickflip from its last frame: same skater, light and skyline.

The skater lands cleanly on the rooftop and rolls toward the camera, then kicks up the board and catches it as the sun dips below the skyline. Board wheels rolling on concrete, a distant crowd cheering.

Astronaut cat catches a star

H3 Max Turbo adds 5 seconds at 480P for 15 credits.

The cat spins in a slow somersault, grabs a passing star with both paws and hugs it, glowing sparks trailing behind. Playful synth melody, a soft purr.
