ComfyUI Node: Video Info (Loaded) 🎥🅥🅗🅢

Video Info (Loaded) 🎥🅥🅗🅢:

The VHS_VideoInfoLoaded node is part of the Video Helper Suite 🎥🅥🅗🅢, designed to provide comprehensive information about a video file. This node extracts and returns both the original (source) and the processed (loaded) video metadata, including frame rate, frame count, duration, width, and height. By utilizing this node, you can gain insights into the video properties before and after processing, which is particularly useful for tasks that require precise video manipulation or analysis. This node is essential for AI artists who need to understand the detailed characteristics of their video files to ensure optimal processing and output quality.

Video Info (Loaded) 🎥🅥🅗🅢 Input Parameters:

video_info

This parameter expects a dictionary containing video metadata. The dictionary should include keys for both the source and loaded video properties, such as source_fps, source_frame_count, source_duration, source_width, source_height, loaded_fps, loaded_frame_count, loaded_duration, loaded_width, and loaded_height. This input is crucial as it provides the necessary data for the node to extract and return the detailed video information.

Video Info (Loaded) 🎥🅥🅗🅢 Output Parameters:

source_fps🟨

This output represents the frame rate (frames per second) of the original video. It indicates how many frames are displayed per second in the source video, which is essential for understanding the video's smoothness and playback speed.

source_frame_count🟨

This output provides the total number of frames in the original video. It helps in determining the length and the amount of data present in the source video.

source_duration🟨

This output indicates the total duration of the original video in seconds. It is useful for understanding the length of the video content.

source_width🟨

This output represents the width of the original video in pixels. It is important for understanding the resolution and aspect ratio of the source video.

source_height🟨

This output provides the height of the original video in pixels. Along with the width, it helps in determining the resolution and aspect ratio of the source video.

loaded_fps🟦

This output represents the frame rate (frames per second) of the processed video. It indicates how many frames are displayed per second in the loaded video, which is essential for understanding the video's smoothness and playback speed after processing.

loaded_frame_count🟦

This output provides the total number of frames in the processed video. It helps in determining the length and the amount of data present in the loaded video.

loaded_duration🟦

This output indicates the total duration of the processed video in seconds. It is useful for understanding the length of the video content after processing.

loaded_width🟦

This output represents the width of the processed video in pixels. It is important for understanding the resolution and aspect ratio of the loaded video.

loaded_height🟦

This output provides the height of the processed video in pixels. Along with the width, it helps in determining the resolution and aspect ratio of the loaded video.

Video Info (Loaded) 🎥🅥🅗🅢 Usage Tips:

• Ensure that the video_info input dictionary contains all the necessary keys for both source and loaded video properties to avoid missing data in the output.
• Use this node to compare the original and processed video properties to verify that the processing steps have been applied correctly and to understand their impact on the video.

Video Info (Loaded) 🎥🅥🅗🅢 Common Errors and Solutions:

KeyError: 'source_fps'

• Explanation: This error occurs when the video_info dictionary does not contain the key source_fps.
• Solution: Ensure that the video_info dictionary includes all required keys for both source and loaded video properties, such as source_fps, source_frame_count, source_duration, source_width, source_height, loaded_fps, loaded_frame_count, loaded_duration, loaded_width, and loaded_height.

KeyError: 'loaded_fps'

• Explanation: This error occurs when the video_info dictionary does not contain the key loaded_fps.
• Solution: Ensure that the video_info dictionary includes all required keys for both source and loaded video properties, such as source_fps, source_frame_count, source_duration, source_width, source_height, loaded_fps, loaded_frame_count, loaded_duration, loaded_width, and loaded_height.

ValueError: Invalid video file

• Explanation: This error occurs when the video file provided in the video_info input is invalid or cannot be processed.
• Solution: Verify that the video file path is correct and that the file is accessible and not corrupted. Ensure that the video file format is supported by the processing tools used in the node.
