ComfyUI Node: H3 MCtx Result Preview (obvpm)

H3 MCtx Result Preview (obvpm):

The H3ResultPreview node is designed to provide a seamless and intuitive way to visualize the results of a video editing process by displaying a mini timeline of a video take alongside its lineage neighbor. This node is particularly useful for quickly assessing whether a new video take effectively connects with its predecessor or successor in a sequence. By wiring the Save node's path output into the H3ResultPreview, users can view a mini timeline that shows the fresh take together with the parent it extends or the clip it prepends. This visualization is achieved through a server-built smart-cut route, similar to the one used by the Timeline node, allowing for a smooth playback of the video pair. The node resolves lineage server-side using the take's sidecar file, ensuring that users can easily determine the connectivity of their video edits at a glance, right where the generation occurred.

H3 MCtx Result Preview (obvpm) Input Parameters:

path

The path parameter is a critical input for the H3ResultPreview node, as it specifies the file path to the video clip that needs to be previewed. This parameter is essential for locating the video file within the output directory, and it must be a valid path that resides within the designated output folder. If the path is incorrect or points to a non-existent file, the node will raise an error. The path parameter does not have a default value, as it is required to be provided by the user to ensure the node functions correctly.

H3 MCtx Result Preview (obvpm) Output Parameters:

ui

The ui output parameter provides a structured JSON object that contains the details necessary for rendering the mini timeline in the user interface. This includes information about the clip, its parent, any secondary parent, the relationship between the clips (such as extends or prepends), and the sequence of clips. Additionally, it includes seam measurements and render details if applicable. This output is crucial for visualizing the connectivity and flow of video takes, allowing users to quickly assess the effectiveness of their edits.

H3 MCtx Result Preview (obvpm) Usage Tips:

• Ensure that the path parameter is correctly set to a valid file within the output directory to avoid errors and ensure smooth operation of the node.
• Use the H3ResultPreview node in conjunction with the Save node to automatically generate and visualize the mini timeline immediately after a video take is saved, providing instant feedback on the edit's connectivity.

H3 MCtx Result Preview (obvpm) Common Errors and Solutions:

H3 MCtx Result Preview (obvpm): <path> is outside the output folder

• Explanation: This error occurs when the specified path is not within the designated output directory, which is required for the node to function correctly.
• Solution: Verify that the path parameter points to a file within the correct output directory and adjust the path if necessary.

H3 MCtx Result Preview (obvpm): clip not found: <path>

• Explanation: This error indicates that the file specified by the path parameter does not exist or cannot be found in the output directory.
• Solution: Check the path parameter to ensure it is correct and that the file exists in the specified location. If the file is missing, ensure it is saved correctly before attempting to preview it.
