PrunaImageToVideoNode - ComfyUI Built-in Node Documentation

Animates an image into a video with Pruna’s P-Video-2 model. The first frame is required and fixes the aspect ratio of the output; an optional last frame gives the video an end point to interpolate towards. The prompt describes how the scene moves, and the node either generates its own soundtrack or takes an audio clip that drives the motion.

Inputs

Common Inputs

Parameter	Description	Data Type	Required	Range
`model`	Pruna video model to use. Selecting a model reveals its own inputs below.	DYNAMIC_COMBO	Yes	`"p-video-2"`

P-Video-2 Inputs

Parameter	Description	Data Type	Required	Range
`model.first_frame`	Image the video starts from. The output keeps the aspect ratio of this image.	IMAGE	Yes	-
`model.last_frame`	Image the video ends on. Its aspect ratio must be close to the first frame’s.	IMAGE	No	-
`model.prompt`	Describes how the scene moves and sounds. Must contain at least one non-whitespace character, up to 5000 characters (default: empty).	STRING	Yes	Up to 5000 characters
`model.duration`	Length of the video in seconds. `"auto"` lets the model choose the length from the prompt. Ignored when `model.audio` is connected: the video then follows the audio length, rounded up to a whole second, up to 20 seconds (default: `"5"`).	COMBO	Yes	`"auto"` `"1"` `"2"` `"3"` `"4"` `"5"` `"6"` `"7"` `"8"` `"9"` `"10"` `"11"` `"12"` `"13"` `"14"` `"15"` `"16"` `"17"` `"18"` `"19"` `"20"`
`model.resolution`	Output resolution. 720p renders about 0.9 megapixels (1280x704 at 16:9), 1080p about 2 megapixels (1920x1088 at 16:9) (default: `"720p"`).	COMBO	Yes	`"720p"` `"1080p"`
`model.fps`	Frames per second. 48 fps is not available with draft at 1080p (default: `"24"`).	COMBO	Yes	`"24"` `"48"`
`model.draft`	Faster, less detailed render, billed at a lower rate than a standard render (default: False).	BOOLEAN	Yes	True/False
`model.generate_audio`	Generate a soundtrack for the video. Ignored when `model.audio` is connected, which becomes the soundtrack instead (default: True).	BOOLEAN	Yes	True/False
`model.enhance_prompt`	Rewrite the prompt with more detail before generation; short prompts need it. Turn it off to reproduce a result exactly with the same seed (default: True). Advanced setting.	BOOLEAN	Yes	True/False
`model.audio`	Audio that drives the motion and becomes the soundtrack. At least 1 second long; audio longer than 20 seconds is truncated. Sets the video length instead of `model.duration`.	AUDIO	No	-
`model.seed`	Seed for the generation. The same seed reproduces a result exactly only when `model.enhance_prompt` is off (default: 42).	INT	Yes	0 to 2147483647

Notes:

model.first_frame is required and fixes the output aspect ratio, so this node has no aspect ratio input.
model.last_frame is optional, but its aspect ratio has to be close to the first frame’s or the node raises an error.
model.prompt is required and limited to 5000 characters.
Draft at 1080p cannot be combined with 48 fps: the node raises an error, so either turn draft off or use 24 fps.
Connected audio must be at least 1 second long; anything past 20 seconds is ignored.
With model.audio connected the audio sets the video length, so model.duration and model.generate_audio have no effect.

Outputs

Output Name	Description	Data Type
`video`	The generated video with its soundtrack.	VIDEO
