Runs the MiniMax H3 first-last frame workflow on a Comfy Cloud GPU and returns the motion between two keyframes with a matching soundtrack.
| Parameter | Description | Data Type | Required | Range |
|---|---|---|---|---|
first_frame | The image the video starts from. It is uploaded at up to 2048x2048 pixels before the workflow runs. | IMAGE | Yes | - |
last_frame | Optional closing frame. When connected, the generated motion ends on this image; without it the motion runs away from first_frame. | IMAGE | No | - |
prompt | The text description of the motion and the sounds the shot should carry. Leading and trailing whitespace is removed before submission. | STRING | Yes | 1 to 4096 characters |
seed | Random seed that controls the generated result (default: 42). | INT | Yes | 0 to 18446744073709551615 |
aspect_ratio | Aspect ratio of the generated video (default: "1:1"). | COMBO | Yes | "1:1""3:4""2:3""3:2""4:3""16:9""9:16""21:9" |
resolution | Frame size budget (default: "480p"). 720p costs roughly twice the GPU-seconds of 480p. | COMBO | Yes | "480p""720p" |
duration_seconds | Length in seconds (default: 5). The pipeline quantises to 17-frame steps at 24 fps, so the clip lands within about two thirds of a second of this value. | INT | Yes | 5 to 15 |
| Output Name | Description | Data Type |
|---|---|---|
VIDEO | The generated video with its soundtrack. | VIDEO |
