Watch the flower video Before and After
The source has fine petal boundaries, purple leaf edges, and shallow-focus texture. Those details make it useful for checking whether a 720p-to-4K result looks cleaner without turning natural surfaces into hard outlines.

WHAT TO INSPECT
Judge the moving result, not one still frame
Compare the red petal boundary against the dark background.
Watch the purple leaf edges as the flower moves through the frame.
Check whether fine texture stays stable instead of flickering between frames.
