ComfyUI Node: 🎥Ultimate Video Loader🎥

🎥Ultimate Video Loader🎥:

The UltimateVideoLoader is a versatile node designed to facilitate the loading of video content from various sources into your AI art projects. This node supports multiple video sources, including YouTube, local file paths, and direct file uploads, making it highly adaptable to different workflows. It can also generate empty video frames for testing purposes. By leveraging this node, you can seamlessly integrate video data into your creative processes, enabling you to work with video frames as easily as you would with static images. The UltimateVideoLoader handles the complexities of video processing, such as frame extraction, resizing, and format conversion, allowing you to focus on your artistic endeavors without worrying about the technical details.

🎥Ultimate Video Loader🎥 Input Parameters:

source

The source parameter specifies the origin of the video content. It can take one of the following values: "YouTube", "filepath", "fileupload", or "emptyvideo". Depending on the selected source, the node will either download the video from YouTube, load it from a local file path, process an uploaded file, or generate empty video frames. This parameter is crucial as it determines the method used to load the video and the subsequent processing steps.

youtube_url

When the source is set to "YouTube", this parameter should contain the URL of the YouTube video to be downloaded. The node will fetch the video from the provided URL and process it accordingly. This parameter is only applicable when the source is "YouTube".

video

For the source set to "filepath" or "fileupload", this parameter should contain the path to the local video file. The node will load the video from the specified path and extract the frames for further processing. This parameter is essential for loading videos from local storage.

upload

When the source is "fileupload", this parameter should contain the path to the uploaded video file. The node will process the uploaded file and extract the frames. This parameter is used to handle video files that are uploaded directly to the node.

frame_count

For the source set to "emptyvideo", this parameter specifies the number of frames to generate. It is used to create a sequence of empty video frames for testing purposes. This parameter is only applicable when generating empty video frames.

width

This parameter specifies the width of the video frames. It is used when the source is "emptyvideo" to define the dimensions of the generated frames. This parameter ensures that the frames have the desired width.

height

This parameter specifies the height of the video frames. Similar to the width parameter, it is used when the source is "emptyvideo" to define the dimensions of the generated frames. This parameter ensures that the frames have the desired height.

fps

The fps parameter specifies the frames per second of the video. It is used to set the frame rate for the generated video frames when the source is "emptyvideo". This parameter ensures that the frames are generated at the desired frame rate.

🎥Ultimate Video Loader🎥 Output Parameters:

images

The images output contains the extracted video frames as a tensor. This tensor can be used in subsequent nodes for further processing or analysis. The frames are organized in a format that is compatible with other nodes in your workflow.

frame_count

The frame_count output provides the total number of frames extracted from the video. This information is useful for understanding the length of the video and for synchronizing with other data.

fps

The fps output indicates the frames per second of the video. This value is important for maintaining the correct timing and synchronization when working with video data.

width

The width output specifies the width of the video frames. This value is essential for ensuring that the frames are processed and displayed correctly.

height

The height output specifies the height of the video frames. Similar to the width output, this value is crucial for maintaining the correct dimensions of the frames during processing.

🎥Ultimate Video Loader🎥 Usage Tips:

• Ensure that the source parameter is set correctly based on the origin of your video content to avoid loading errors.
• When using YouTube as the source, provide a valid youtube_url to ensure the video is downloaded correctly.
• For local file paths, make sure the video parameter points to an existing and accessible file to prevent loading issues.
• Use the frame_count, width, height, and fps parameters to generate empty video frames for testing and debugging purposes.

🎥Ultimate Video Loader🎥 Common Errors and Solutions:

"No frames generated"

• Explanation: This error occurs when the node fails to extract any frames from the video.
• Solution: Ensure that the video file is accessible and not corrupted. Verify that the source parameter is set correctly and that the video path or URL is valid.

"Video could not be loaded with cv"

• Explanation: This error indicates that the video file could not be opened using OpenCV.
• Solution: Check the file path and ensure that the video file exists and is not corrupted. Verify that the file format is supported by OpenCV.

"Invalid YouTube URL"

• Explanation: This error occurs when the provided YouTube URL is not valid or accessible.
• Solution: Ensure that the youtube_url parameter contains a valid and accessible YouTube video URL. Verify that the URL is correctly formatted and that the video is available for download.

"Empty video parameters missing"

• Explanation: This error occurs when the required parameters for generating empty video frames are not provided.
• Solution: Ensure that the frame_count, width, height, and fps parameters are specified when the source is set to "emptyvideo". Verify that all required parameters are provided and correctly set.
