ComfyUI Node: AudioX Video to Audio

AudioX Video to Audio:

The AudioXVideoToAudio node is designed to transform visual content from a video into a corresponding audio track, leveraging the capabilities of the AudioX model. This node is particularly useful for generating realistic audio that matches the visual elements and actions depicted in a video. By using a text prompt, you can guide the audio generation process to produce sounds that align with the video's context, enhancing the overall multimedia experience. The node's primary goal is to bridge the gap between visual and auditory content, making it an invaluable tool for AI artists looking to create immersive audiovisual projects.

AudioX Video to Audio Input Parameters:

model

This parameter specifies the AudioX model to be used for generating audio from the video input. The model is responsible for interpreting the video content and producing the corresponding audio. Selecting the appropriate model can significantly impact the quality and realism of the generated audio.

video

The video parameter accepts a video input in the ComfyUI format. This video serves as the source material from which the audio will be generated. The visual content and actions within the video are analyzed to create a matching audio track.

text_prompt

The text_prompt parameter allows you to provide a descriptive prompt that guides the audio generation process. This prompt should describe the type of audio you want to generate, ensuring it aligns with the visual content of the video. The default prompt is "Generate realistic audio that matches the visual content and actions in this video," but you can customize it to suit your specific needs.

steps

This parameter determines the number of steps the model will take during the audio generation process. It ranges from 1 to 1000, with a default value of 250. Increasing the number of steps can enhance the detail and quality of the generated audio, but it may also increase processing time.

cfg_scale

The cfg_scale parameter controls the influence of the text prompt on the audio generation. It ranges from 0.1 to 20.0, with a default value of 7.0. A higher value increases the prompt's impact, potentially leading to audio that more closely matches the described scenario.

seed

The seed parameter is used to initialize the random number generator, ensuring reproducibility of the audio generation process. It ranges from -1 to 2^32 - 1, with a default value of -1. Using the same seed will produce the same audio output for identical inputs.

duration_seconds

This parameter specifies the duration of the generated audio in seconds. It ranges from 1.0 to 30.0, with a default value of 10.0. Adjusting this parameter allows you to control the length of the audio track to match the video's duration or your specific requirements.

AudioX Video to Audio Output Parameters:

audio

The audio output parameter provides the generated audio track that corresponds to the input video. This audio is crafted to match the visual content and actions depicted in the video, creating a cohesive and immersive audiovisual experience. The quality and realism of the audio depend on the input parameters and the selected model.

AudioX Video to Audio Usage Tips:

• Use a detailed and specific text prompt to guide the audio generation process effectively, ensuring the resulting audio aligns well with the video's content.
• Experiment with different cfg_scale values to find the right balance between the influence of the text prompt and the natural interpretation of the video content by the model.
• Adjust the steps parameter to improve the quality of the generated audio, keeping in mind that higher values may increase processing time.

AudioX Video to Audio Common Errors and Solutions:

"Model not found"

• Explanation: This error occurs when the specified AudioX model is not available or incorrectly specified.
• Solution: Ensure that the model parameter is set to a valid and available AudioX model. Check for any typos or incorrect model names.

"Invalid video format"

• Explanation: The video input is not in the expected ComfyUI format, leading to processing issues.
• Solution: Convert your video to the ComfyUI format before using it as input. Verify that the video file is correctly formatted and compatible with the node.

"Text prompt too vague"

• Explanation: The text prompt provided is too general, resulting in audio that does not match the video's content well.
• Solution: Refine the text prompt to be more specific and descriptive, clearly outlining the desired audio characteristics and how they relate to the video content.
