ComfyUI Node: HunyuanVideo Fresca

HunyuanVideo Fresca:

HunyuanVideoFresca is a specialized node designed to enhance video processing by applying the FreSca method, which is known for its ability to manipulate frequency scales in video data. This node is particularly useful for artists and creators looking to achieve specific visual effects by adjusting the frequency components of their videos. By providing a range of parameters to control the scale and frequency cutoff, HunyuanVideoFresca allows for fine-tuning of video outputs, making it a powerful tool for creative video transformations. The node's primary goal is to offer flexibility and precision in video editing, enabling users to explore a wide array of visual styles and effects.

HunyuanVideo Fresca Input Parameters:

fresca_scale_low

This parameter sets the lower bound of the frequency scale adjustment. It determines the minimum scale factor applied to the video frequencies, allowing you to control the extent of the effect. The value ranges from 0.0 to 10.0, with a default of 1.0. Adjusting this parameter can help in achieving subtle or pronounced changes in the video texture.

fresca_scale_high

This parameter defines the upper bound of the frequency scale adjustment. It specifies the maximum scale factor for the video frequencies, providing a range within which the effect can vary. The value ranges from 0.0 to 10.0, with a default of 1.25. By modifying this parameter, you can enhance or diminish the impact of the frequency scaling on the video.

fresca_freq_cutoff

This parameter sets the frequency cutoff point, which determines the threshold at which frequencies are affected by the scaling. It ranges from 0 to 10000, with a default value of 20. This parameter is crucial for controlling which parts of the frequency spectrum are altered, allowing for targeted adjustments to the video content.

HunyuanVideo Fresca Output Parameters:

fresca_args

The output parameter fresca_args provides a structured set of arguments that encapsulate the settings used for the frequency scaling process. This output is essential for understanding the specific configuration applied to the video, enabling users to replicate or adjust the effect in future projects. It serves as a reference for the parameters that influenced the final video output.

HunyuanVideo Fresca Usage Tips:

• Experiment with different fresca_scale_low and fresca_scale_high values to achieve a variety of visual effects, from subtle enhancements to dramatic transformations.
• Use the fresca_freq_cutoff parameter to focus the effect on specific frequency ranges, allowing for precise control over which aspects of the video are altered.

HunyuanVideo Fresca Common Errors and Solutions:

Invalid parameter range

• Explanation: This error occurs when input parameters are set outside their allowed ranges.
• Solution: Ensure that all input parameters are within their specified minimum and maximum values as described in the input parameter section.

Unexpected output appearance

• Explanation: The video output may not look as expected if the frequency scaling parameters are not set appropriately.
• Solution: Adjust the fresca_scale_low, fresca_scale_high, and fresca_freq_cutoff parameters incrementally to fine-tune the visual effect until the desired outcome is achieved.
