ComfyUI Node: Load Video And Segment

Load Video And Segment:

The LoadVideoAndSegment_ node is designed to facilitate the loading and segmentation of video files within the ComfyUI framework. This node allows you to import a video, process it frame by frame, and segment it into smaller clips based on specified parameters. The primary benefit of this node is its ability to handle video files efficiently, converting frames into a format suitable for further processing or analysis within ComfyUI. It supports various operations such as frame extraction, color conversion, and segmentation, making it a versatile tool for video manipulation tasks. By using this node, you can easily manage large video files, extract meaningful segments, and prepare them for subsequent processing steps, enhancing your workflow's efficiency and effectiveness.

Load Video And Segment Input Parameters:

video

This parameter specifies the path to the video file you want to load and segment. It is essential for the node to locate and access the video file for processing. Ensure the path is correct and the file is accessible.

video_segment_frames

This parameter defines the number of frames each segment should contain. If set to -1, the video will not be segmented. The default value is -1, and it can be adjusted based on the desired segment length.

transition_frames

This parameter specifies the number of transition frames between segments. It helps in creating smooth transitions between video segments. The default value is 0, and it can be adjusted to achieve the desired transition effect.

frame_load_cap

This parameter sets a limit on the number of frames to load from the video. If set to a positive value, the node will stop processing frames once this limit is reached. The default value is 0, indicating no limit.

skip_first_frames

This parameter determines the number of initial frames to skip before starting the processing. It is useful for ignoring unwanted initial frames. The default value is 0, and it can be adjusted based on the specific requirements.

Load Video And Segment Output Parameters:

scenes_video

This output provides a list of segmented video files. Each segment is saved as a separate video file, allowing for easy access and further processing.

scenes_count

This output indicates the total number of video segments created. It helps in understanding the extent of segmentation performed on the input video.

frame_count

This output provides the total number of frames processed from the input video. It is useful for verifying the completeness of the frame extraction process.

fps

This output indicates the frames per second (FPS) of the input video. It helps in understanding the video's playback speed and can be useful for synchronization purposes.

Load Video And Segment Usage Tips:

• Ensure the video file path is correct and accessible to avoid loading errors.
• Adjust the video_segment_frames parameter to control the length of each video segment based on your requirements.
• Use the transition_frames parameter to create smooth transitions between segments, enhancing the visual continuity.
• Set the frame_load_cap parameter to limit the number of frames processed, which can be useful for handling large video files.
• Skip unwanted initial frames by configuring the skip_first_frames parameter, ensuring only relevant frames are processed.

Load Video And Segment Common Errors and Solutions:

"Video could not be loaded with cv fallback."

• Explanation: This error occurs when the video file cannot be opened using OpenCV.
• Solution: Verify the video file path and ensure the file is accessible. Check if the file format is supported by OpenCV.

"Invalid image file: <video>"

• Explanation: This error indicates that the specified video file path is invalid or the file does not exist.
• Solution: Double-check the video file path and ensure the file exists at the specified location.

"Frame load cap reached."

• Explanation: This message indicates that the frame load cap limit has been reached during processing.
• Solution: Increase the frame_load_cap parameter if you need to process more frames, or set it to 0 for no limit.

"Error during frame extraction."

• Explanation: This error occurs if there is an issue during the frame extraction process.
• Solution: Ensure the video file is not corrupted and is in a supported format. Check for any issues with the video file itself.
