ComfyUI Node: Load Video from URL

Load Video from URL:

The LoadVideoURL node is designed to facilitate the process of loading video content directly from a URL. This node is particularly useful for AI artists who need to work with video data sourced from the internet, allowing them to seamlessly integrate online video resources into their creative workflows. By downloading the video to a temporary file and utilizing OpenCV for video processing, this node provides a streamlined method for accessing video properties such as frame rate, resolution, and duration. This capability is essential for tasks that require precise video manipulation or analysis, making it a valuable tool for projects involving video-based AI art generation.

Load Video from URL Input Parameters:

url

The url parameter specifies the web address from which the video will be downloaded. It is crucial for directing the node to the correct online resource. The URL must be valid and accessible to ensure successful video retrieval. There are no specific minimum or maximum values, but it must be a properly formatted URL.

force_rate

The force_rate parameter allows you to specify a desired frame rate for the video. This can be useful if you need to standardize the frame rate across different videos for consistency in processing. The parameter accepts numerical values representing frames per second (fps).

force_size

The force_size parameter enables you to enforce a specific resolution for the video. This is beneficial when working with videos of varying resolutions and you need to maintain a uniform size for processing. The parameter typically accepts values in the format of width x height.

custom_width

The custom_width parameter allows you to set a specific width for the video, overriding the original width. This can be useful for resizing videos to fit specific requirements or constraints. The parameter accepts numerical values representing the width in pixels.

custom_height

The custom_height parameter allows you to set a specific height for the video, overriding the original height. Similar to custom_width, this is useful for resizing videos to meet particular needs. The parameter accepts numerical values representing the height in pixels.

frame_load_cap

The frame_load_cap parameter limits the number of frames loaded from the video. This can be useful for reducing processing time and resource usage when working with long videos. The parameter accepts numerical values representing the maximum number of frames to load.

skip_first_frames

The skip_first_frames parameter allows you to skip a specified number of frames at the beginning of the video. This can be useful for ignoring introductory content or focusing on specific segments of the video. The parameter accepts numerical values representing the number of frames to skip.

select_every_nth

The select_every_nth parameter enables you to select every nth frame from the video, which can be useful for creating time-lapse effects or reducing the number of frames for processing. The parameter accepts numerical values indicating the interval of frames to select.

Load Video from URL Output Parameters:

VideoFromFile

The VideoFromFile output parameter represents the video data that has been loaded and processed from the specified URL. This output is crucial for further video manipulation or analysis within your AI art projects. It provides access to the video content in a format that can be easily integrated into subsequent processing nodes or workflows.

Load Video from URL Usage Tips:

• Ensure that the URL provided is accessible and points directly to a video file to avoid download errors.
• Use the force_rate and force_size parameters to standardize video properties across different sources, ensuring consistency in your projects.
• Utilize the frame_load_cap and select_every_nth parameters to manage processing resources effectively, especially when dealing with large or high-resolution videos.

Load Video from URL Common Errors and Solutions:

Invalid video file: <file>

• Explanation: This error occurs when the specified URL does not point to a valid video file or the file cannot be accessed.
• Solution: Verify that the URL is correct and accessible. Ensure that it points directly to a downloadable video file.

No video data was returned

• Explanation: This error indicates that the video could not be downloaded or processed, possibly due to network issues or an invalid URL.
• Solution: Check your internet connection and ensure the URL is valid. Retry the operation after confirming these aspects.
