Ridgeline Honey, Twice the Pixels
A 5-second 1024x576 packshot clip upscaled 2x to 2048x1152, with its frames, frame rate and sound kept.
Exact clip upscale doubles every frame of a short clip with Real-ESRGAN and rebuilds the video at the same frame rate with the original sound. Nothing is redrawn, so a label stays as the shot had it, for better and worse: here the bold type sharpens, and the H3 clip's slightly garbled small print stays exactly as it was.
To make your own, hand Wavemaker a clip of up to about 10 seconds at 720p or less. It returns an MP4 at twice the size with the same frames and sound. For added detail on video, ask for a SeedVR2 pass instead.
