ComfyUI Node: Motionctrl-SVD Sample Simple

Motionctrl-SVD Sample Simple:

The Motionctrl-SVD Sample Simple node is designed to facilitate the generation of motion-controlled video samples using Singular Value Decomposition (SVD) techniques. This node leverages a pre-trained model to create dynamic video frames based on input images and specified camera parameters. It is particularly useful for AI artists looking to add motion effects to their static images, transforming them into engaging video content. The node simplifies the process by handling complex computations and providing an easy-to-use interface for setting parameters such as camera movements, frame rate, and seed for randomization. By using this node, you can achieve high-quality motion effects with minimal effort, making it an essential tool for creative video generation.

Motionctrl-SVD Sample Simple Input Parameters:

model

This parameter specifies the pre-trained model to be used for generating the motion-controlled video. The model is identified by the string "MOTIONCTRLSVD". This model contains the necessary configurations and weights to perform the SVD-based video sampling.

camera

The camera parameter is a string that defines the camera movements in a multiline format. The default value is "[[1,0,0,0,0,1,0,0,0,0,1,0.2]]", which represents a specific camera pose. This parameter allows you to control the camera's position and orientation, thereby influencing the motion effect in the generated video.

image

The image parameter accepts an input image that will be used as the base for generating the video frames. This image serves as the starting point for the motion effects applied by the model.

resize_mode

The resize_mode parameter determines how the input image should be resized before processing. This ensures that the image dimensions are compatible with the model's requirements, optimizing the quality of the generated video.

seed

The seed parameter is an integer used for randomization purposes. It has a default value of 1234. By setting a specific seed, you can ensure reproducibility of the generated video, as the same seed will produce the same random effects.

fps_id

The fps_id parameter specifies the frame rate of the generated video. It is an integer with a default value of 6, and it can range from a minimum of 5 to a maximum of 30. This parameter controls the smoothness of the motion in the video.

frame_length

The frame_length parameter defines the number of frames to be generated in the video. It is an integer with a default value of 14. This parameter determines the duration of the video and the extent of the motion effect.

Motionctrl-SVD Sample Simple Output Parameters:

IMAGE

The output parameter IMAGE is the generated video frames based on the input image and specified parameters. This output is a sequence of images that together form a video, showcasing the applied motion effects. The generated video can be used for various creative purposes, such as animations, presentations, or artistic projects.

Motionctrl-SVD Sample Simple Usage Tips:

• Experiment with different camera parameter values to achieve various motion effects and perspectives in your video.
• Adjust the fps_id parameter to find the optimal frame rate that suits the style and smoothness you desire for your video.
• Use the seed parameter to create multiple variations of the same motion effect, ensuring diversity in your generated content.

Motionctrl-SVD Sample Simple Common Errors and Solutions:

Invalid camera parameter format

• Explanation: The camera parameter must be in a specific multiline string format.
• Solution: Ensure that the camera parameter follows the format "[[1,0,0,0,0,1,0,0,0,0,1,0.2]]" or similar.

Image size mismatch

• Explanation: The input image dimensions may not be compatible with the model's requirements.
• Solution: Use the resize_mode parameter to adjust the image size before processing.

Seed value out of range

• Explanation: The seed value must be an integer.
• Solution: Ensure that the seed parameter is set to a valid integer value, such as 1234.

FPS value out of range

• Explanation: The fps_id parameter must be within the range of 5 to 30.
• Solution: Set the fps_id parameter to a value between 5 and 30 to ensure proper frame rate settings.
