Flux3MaxImageToVideoNode - ComfyUI Built-in Node Documentation

FLUX 3 Max Image to Video animates 1 to 10 images with FLUX 3 Max. Each image becomes a frame of the clip: one image opens it, two become its first and last frame, and more are spread across the clip or pinned to times you choose.

Inputs

Parameter	Description	Data Type	Required	Range
`prompt`	How the scene should move and sound (default: empty).	STRING	Yes	Multiline text
`keyframes`	Growable slot: connect 1 to 10 keyframe images in playback order, e.g. `image_1`, `image_2`, and so on. Each image becomes a frame of the clip.	IMAGE	Yes	1 to 10 images
`placement`	`"spread across the clip"` puts the first image at the start, the last at the end and the rest evenly between; `"at times"` pins every image to a second you choose (default: `"spread across the clip"`).	DYNAMIC_COMBO	Yes	`"spread across the clip"` `"at times"`
`aspect_ratio`	Output aspect ratio. `"auto"` follows the first keyframe image (default: `"auto"`).	COMBO	Yes	`"auto"` `"21:9"` `"2:1"` `"16:9"` `"4:3"` `"1:1"` `"3:4"` `"9:16"`
`duration`	Clip length in seconds (default: `"5"`).	COMBO	Yes	`"5"` `"6"` `"7"` `"8"` `"9"` `"10"` `"11"` `"12"` `"13"` `"14"` `"15"` `"16"` `"17"` `"18"` `"19"` `"20"`
`resolution`	Output resolution (default: `"720p"`).	COMBO	Yes	`"720p"` `"1080p"`
`reasoning_level`	How much the model reasons about and expands the prompt before generating. `"high"` takes longer; the price is the same (default: `"high"`).	COMBO	Yes	`"low"` `"high"`
`generate_audio`	Generate synchronized audio. Off produces a video with no audio track (default: true).	BOOLEAN	Yes	`true` `false`
`seed`	Seed controlling whether the node re-runs. Results are non-deterministic regardless of this value (default: 42).	INT	Yes	0 to 2147483646

at times Inputs

Parameter	Description	Data Type	Required	Range
`times`	One time in seconds per image, comma-separated and increasing, e.g. “0, 2.5, 5”. Only appears when `placement` is `"at times"`.	STRING	No	Comma-separated seconds

Note: prompt must contain at least one character. keyframes must hold at least one image and cannot hold more than 10; a batched input counts once per image. With placement set to "spread across the clip", one or two images are sent as the start image and an optional end image, while three or more are placed on keyframes spread evenly across the clip at 24 fps. With placement set to "at times", times must give one value per image and those values must increase, cannot be negative, and the last time cannot be past the end of the clip. The displayed price is based on resolution and duration: 720p is charged at $0.060775 per second and 1080p at $0.103675 per second until November 7, 2026, and at $0.2431 and $0.4147 per second after that date. The total estimated cost for the clip is shown in the UI.

Outputs

Output Name	Description	Data Type
`video`	The generated video clip built from the keyframe images at the chosen aspect ratio, duration, resolution, and audio setting.	VIDEO
