ComfyUI Node: 🎥Ultimate Video Loader (simple)🎥

UltimateVideoLoader (simple):

The UltimateVideoLoader is a versatile node designed to load video content from various sources, including YouTube, local file paths, and uploaded files. It can also generate empty video frames for testing purposes. This node is particularly useful for AI artists who need to process video data for their projects, as it simplifies the process of extracting frames and relevant metadata such as frame count, frames per second (fps), and video dimensions. By leveraging this node, you can seamlessly integrate video content into your workflows, enabling more dynamic and engaging AI-generated art.

UltimateVideoLoader (simple) 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 essential for loading video content directly from YouTube.

video

For source set to "filepath" or "fileupload", this parameter should contain the path to the local video file. The node will read the video from the specified path and extract the frames. This parameter is necessary for loading video content 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 important for handling video content that is uploaded by the user.

frame_count

For 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 required when generating empty video frames.

width

For source set to "emptyvideo", this parameter specifies the width of the generated video frames. It is used to define the dimensions of the empty video frames. This parameter is required when generating empty video frames.

height

For source set to "emptyvideo", this parameter specifies the height of the generated video frames. It is used to define the dimensions of the empty video frames. This parameter is required when generating empty video frames.

fps

For source set to "emptyvideo", this parameter specifies the frames per second (fps) of the generated video frames. It is used to define the frame rate of the empty video frames. This parameter is required when generating empty video frames.

UltimateVideoLoader (simple) Output Parameters:

images

This output parameter contains the extracted frames from the video as a tensor. Each frame is represented as a 3D tensor with dimensions corresponding to height, width, and color channels. This parameter is essential for further processing and analysis of the video content.

frame_count

This output parameter indicates the total number of frames extracted from the video. It provides valuable information about the length of the video in terms of frames, which can be used for synchronization and timing purposes.

fps

This output parameter specifies the frames per second (fps) of the video. It is crucial for understanding the frame rate of the video, which affects the smoothness and playback speed of the content.

width

This output parameter indicates the width of the video frames. It provides information about the horizontal resolution of the video, which is important for display and processing purposes.

height

This output parameter indicates the height of the video frames. It provides information about the vertical resolution of the video, which is important for display and processing purposes.

UltimateVideoLoader (simple) Usage Tips:

• Ensure that the source parameter is correctly set to match the origin of your video content to avoid loading errors.
• When using the "YouTube" 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 video file.
• When generating empty video frames, specify appropriate values for frame_count, width, height, and fps to match your testing requirements.

UltimateVideoLoader (simple) 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 URL or file path is valid.

"Video could not be loaded with cv"

• Explanation: This error occurs when the node is unable to open the video file using OpenCV.
• Solution: Check that the video file exists at the specified path and is not corrupted. Ensure that the file format is supported by OpenCV.

"Invalid YouTube URL"

• Explanation: This error occurs when the provided YouTube URL is not valid or cannot be accessed.
• Solution: Verify that the YouTube URL is correct and that the video is publicly accessible. Ensure that there are no typos in the URL.
