ComfyUI Node: Video Chromatic Aberration

Video Chromatic Aberration:

The VideoChromaticAberration node is designed to simulate the chromatic aberration effect commonly seen in optical lenses, where different colors of light are refracted by varying amounts, causing a slight misalignment of colors. This node is particularly useful for adding a realistic touch to video content by introducing subtle color shifts that mimic the imperfections of real-world lenses. By applying this effect, you can enhance the visual appeal of your videos, giving them a more cinematic and professional look. The node achieves this by shifting the red and blue channels of the video frames, creating a distinctive color fringing effect that can be adjusted in intensity to suit your artistic vision.

Video Chromatic Aberration Input Parameters:

effect_intensity

The effect_intensity parameter controls the strength of the chromatic aberration effect applied to the video. A higher value results in a more pronounced color shift, while a lower value produces a subtler effect. This parameter allows you to fine-tune the visual impact of the chromatic aberration, making it possible to achieve anything from a barely noticeable effect to a dramatic color distortion. The default value is 1.0, with a minimum of 0.0 and a maximum of 5.0, adjustable in increments of 0.1.

chromatic_blur

The chromatic_blur parameter determines the amount of blur applied to the chromatic aberration effect. This can help to soften the edges of the color shifts, creating a more natural and less harsh appearance. By adjusting this parameter, you can control the smoothness of the transition between colors, enhancing the overall aesthetic of the effect. The default value is 0.0, with a minimum of 0.0 and a maximum of 10.0, adjustable in increments of 0.1.

Video Chromatic Aberration Output Parameters:

processed_video

The processed_video output parameter provides the video with the applied chromatic aberration effect. This output is the result of the node's processing, where the specified intensity and blur settings have been used to alter the original video frames. The processed video will exhibit the characteristic color fringing effect, adding a layer of visual complexity and realism to your project.

Video Chromatic Aberration Usage Tips:

• Experiment with different effect_intensity values to find the right balance for your project. A subtle effect can add realism without being distracting, while a stronger effect can be used for artistic emphasis.
• Use the chromatic_blur parameter to smooth out the color transitions, especially if the initial effect appears too harsh or artificial. This can help integrate the effect more seamlessly into your video.

Video Chromatic Aberration Common Errors and Solutions:

"Invalid effect_intensity value"

• Explanation: This error occurs when the effect_intensity value is set outside the allowed range of 0.0 to 5.0.
• Solution: Ensure that the effect_intensity value is within the specified range and adjust it using increments of 0.1.

"Invalid chromatic_blur value"

• Explanation: This error is triggered when the chromatic_blur value is set outside the permissible range of 0.0 to 10.0.
• Solution: Verify that the chromatic_blur value is within the allowed range and adjust it using increments of 0.1.
