ComfyUI Node: 🌊 Depthflow

🌊 Depthflow:

Depthflow is a powerful node designed to apply dynamic motion animations to images using depth maps, enhancing the visual storytelling in your projects. By leveraging various motion presets such as Zoom, Dolly, Circle, Horizontal, and Vertical, Depthflow allows you to create captivating animations that bring static images to life. This node is particularly beneficial for artists looking to add depth and movement to their visuals, making them more engaging and immersive. The core functionality of Depthflow revolves around transforming an image into a sequence of frames, which can then be compiled into a video, offering a seamless way to integrate motion into your creative workflow. Its ability to handle different motion types and customize output settings makes it an essential tool for artists aiming to explore new dimensions in their visual art.

🌊 Depthflow Input Parameters:

image

The input image parameter is the starting point for the Depthflow node, serving as the base visual that will undergo motion transformation. This parameter is crucial as it determines the initial content and quality of the animation. The image should be of high resolution to ensure the best results after processing.

depth_map

The depth_map parameter provides the necessary depth information corresponding to the input image. It is used to calculate the perceived distance of objects within the image, allowing the node to apply realistic motion effects. A well-defined depth map enhances the accuracy and quality of the motion animation.

options

The options parameter refers to a DepthState object that contains various settings and configurations for the node. This parameter allows you to customize the behavior of the Depthflow node, tailoring it to specific artistic needs or project requirements.

motion

The motion parameter is a Depthflow motion object that defines the type of motion to be applied to the image. This could be any of the available presets like Zoom, Dolly, Circle, etc. The choice of motion significantly impacts the final animation, influencing its style and dynamism.

input_fps

The input_fps parameter specifies the frames per second for the input video, determining the smoothness and speed of the initial animation sequence. A higher FPS results in smoother motion but may require more processing power.

output_fps

The output_fps parameter sets the frames per second for the output video, affecting the final animation's fluidity and playback speed. Adjusting this parameter can help achieve the desired pacing and visual effect in the output.

num_frames

The num_frames parameter indicates the number of frames to be generated for the output video. This directly influences the duration of the animation, with more frames resulting in a longer video.

quality

The quality parameter controls the quality of the output video, balancing between file size and visual fidelity. Higher quality settings produce better-looking videos but may increase rendering time and file size.

ssaa

The ssaa parameter stands for Super Sampling Anti-Aliasing samples, which helps reduce aliasing artifacts in the output video. Increasing this value can improve image quality by smoothing edges, though it may also increase processing time.

invert

The invert parameter allows you to invert the depth map, reversing the perceived depth in the image. This can be useful for creating unique visual effects or correcting depth map errors.

tiling_mode

The tiling_mode parameter determines how the image is tiled during processing, affecting how the motion is applied across the image. Different tiling modes can produce varied visual effects, offering additional creative control.

🌊 Depthflow Output Parameters:

image_batch

The image_batch output parameter is a tensor containing the sequence of frames generated by the Depthflow node. This batch represents the animated transformation of the input image, ready for further processing or compilation into a video.

🌊 Depthflow Usage Tips:

• Experiment with different motion presets to find the one that best suits your artistic vision. Each preset offers a unique style and can dramatically change the feel of your animation.
• Adjust the input and output FPS settings to control the smoothness and speed of your animation. Higher FPS values generally result in smoother motion but may require more computational resources.
• Use the quality parameter to balance between visual fidelity and file size. For high-quality projects, prioritize quality, but for quick previews, consider lowering it to save time.

🌊 Depthflow Common Errors and Solutions:

"Invalid depth map"

• Explanation: This error occurs when the provided depth map does not match the input image or is corrupted.
• Solution: Ensure that the depth map corresponds accurately to the input image and is in a compatible format.

"Motion object not defined"

• Explanation: This error indicates that the motion parameter has not been set or is incorrectly configured.
• Solution: Verify that a valid Depthflow motion object is assigned to the motion parameter and that it is properly configured.

"Output FPS too high"

• Explanation: The specified output FPS is too high for the current system capabilities, leading to processing issues.
• Solution: Reduce the output FPS to a level that your system can handle without compromising performance.
