Output specifications
The H3 Pro API accepts five aspect ratios: 16:9, 9:16, 1:1, 3:4 and 4:3. Execution depends on the specifications verified on available nodes. Landscape/portrait size examples: 832 × 480 / 480 × 832 at 480p; 1280 × 736 / 736 × 1280 at 720p. Output is 24 fps with audio by default; generate_audio=false mutes it. The 5-second preset contains 124 frames, approximately 5.17 seconds.
1080p, custom aspect ratios, multiple reference images, first-and-last frames, video or audio references, draft mode and fixed-camera parameters are not supported.
