ComfyUI Node: AudioX Video to Music

AudioX Video to Music:

The AudioXVideoToMusic node is designed to transform video content into a musical composition using the AudioX framework. This node leverages advanced algorithms to analyze the visual elements of a video and generate a corresponding musical piece that enhances the viewer's experience. By integrating video analysis with music generation, it provides a unique tool for creators looking to add an auditory dimension to their visual projects. The node is particularly beneficial for artists and designers who wish to create immersive multimedia experiences without needing extensive technical knowledge in music production. Its primary function is to interpret the mood, tempo, and dynamics of a video and translate these elements into a harmonious audio output, making it an essential tool for enhancing storytelling through synchronized audio-visual content.

AudioX Video to Music Input Parameters:

model

The model parameter specifies the AudioX model to be used for generating music. This model is responsible for interpreting the video content and creating a musical composition that aligns with the visual elements. The choice of model can significantly impact the style and quality of the generated music.

video

The video parameter is the input video file in ComfyUI's video format. This video serves as the source material from which the node extracts visual cues to generate music. The content, pace, and mood of the video will influence the resulting audio output.

text_prompt

The text_prompt parameter allows you to provide a textual description or guidance for the type of music you want to generate. It defaults to "Generate music for the video" and supports multiline input. This prompt helps the model understand the desired style or mood of the music, offering a way to customize the output to better fit your creative vision.

steps

The steps parameter determines the number of processing steps the model will take to generate the music. It ranges from 1 to 1000, with a default value of 250. More steps can lead to more refined and detailed music, but may also increase processing time.

cfg_scale

The cfg_scale parameter is a floating-point value that controls the influence of the text prompt on the music generation process. It ranges from 0.1 to 20.0, with a default of 7.0. A higher value gives more weight to the text prompt, potentially resulting in music that closely aligns with the specified description.

seed

The seed parameter is an integer used to initialize the random number generator for the music generation process. It ranges from -1 to 2^32

• 1, with a default of -1, which indicates a random seed. Using a specific seed allows for reproducibility of results, enabling you to generate the same music output for the same input parameters.

duration_seconds

The duration_seconds parameter specifies the length of the generated music in seconds. It ranges from 1.0 to 30.0, with a default value of 10.0. This parameter allows you to control the duration of the audio output to match the length of the video or fit specific project requirements.

AudioX Video to Music Output Parameters:

audio

The audio output parameter is the generated music file that corresponds to the input video. This audio file encapsulates the musical interpretation of the video's visual content, providing an auditory layer that enhances the overall multimedia experience. The quality and style of the music are influenced by the input parameters, such as the model, text prompt, and cfg_scale.

AudioX Video to Music Usage Tips:

• Experiment with different text_prompt values to guide the music generation towards a specific mood or style that complements your video content.
• Adjust the cfg_scale to find the right balance between the influence of the text prompt and the inherent characteristics of the video when generating music.
• Use a specific seed value if you need to reproduce the same music output for consistency across multiple iterations or projects.

AudioX Video to Music Common Errors and Solutions:

Invalid video format

• Explanation: The input video is not in the required ComfyUI video format.
• Solution: Ensure that the video is converted to the correct format before using it as input for the node.

Model not found

• Explanation: The specified AudioX model is not available or incorrectly specified.
• Solution: Verify that the model name is correct and that it is installed and accessible in your environment.

Out of range parameter value

• Explanation: One or more input parameters are set outside their allowed range.
• Solution: Check the parameter values and ensure they fall within the specified minimum and maximum limits. Adjust them accordingly.
