Drop a file, or

Source video fitted to the target canvas without changing its timeline or audio. Accepted duration ranges from 0.25 to 300 seconds.

aspect_ratio default 16:9

Canvas proportions for outpainting around the source video. The entire source fits inside this canvas, with outpainting filling any uncovered area.

resolution default 768p

Canvas resolution profile, with 1080p obtained through learned latent upscaling rather than native reframing at that size. Its underlying reframe is generated natively at 768p.

About H3 Max Reframe

Fits the source video (0.25 to 300 seconds) onto a target canvas and generates the surrounding area. `aspect_ratio` options are 16:9, 9:16, 1:1, 4:3, 3:4, 21:9 and 9:21. An optional `prompt` guides the new surroundings. `resolution` is 480p, 768p or 1080p, with 1080p upscaled from a native 768p reframe.
