ComfyUI Node: 📹🔗 Concat Videos

📹🔗 Concat Videos:

The Bjornulf_ConcatVideos node is designed to seamlessly concatenate multiple video files into a single continuous video. This node is particularly useful for AI artists and creators who need to merge several video clips into one cohesive piece without the hassle of manual editing. By automating the concatenation process, it saves time and effort, allowing you to focus on the creative aspects of your project. The node ensures that the transition between videos is smooth, maintaining the original quality and format of the input videos. This functionality is essential for creating longer narratives or presentations from shorter clips, making it a valuable tool in video production workflows.

📹🔗 Concat Videos Input Parameters:

video_paths

This parameter accepts a list of file paths pointing to the video files you wish to concatenate. Each path should be a valid string representing the location of a video file on your system. The order of the paths in the list determines the sequence in which the videos will be concatenated. Ensure that all video files are in a compatible format to avoid errors during processing. There are no specific minimum or maximum values for this parameter, but it is important to provide at least two video paths to perform concatenation.

output_format

This parameter specifies the format of the output video file. Common formats include "mp4", "avi", and "mov". The choice of format can affect the compatibility and quality of the final video, so it is important to select a format that suits your needs and the platforms where the video will be used. The default value is typically "mp4", which is widely supported and offers a good balance between quality and file size.

📹🔗 Concat Videos Output Parameters:

concatenated_video_path

This output parameter provides the file path to the newly created video that results from concatenating the input videos. The path is a string that indicates where the output video is saved on your system. This allows you to easily locate and use the concatenated video in your projects or for further editing. The output video retains the quality and format specified in the input parameters, ensuring a seamless integration into your workflow.

📹🔗 Concat Videos Usage Tips:

• Ensure all input video files are in the same format and resolution to avoid compatibility issues during concatenation.
• Use the output_format parameter to specify a format that is compatible with your intended use, such as "mp4" for web use or "mov" for high-quality editing.
• Double-check the order of video paths in the video_paths parameter to ensure the final video sequence matches your creative vision.

📹🔗 Concat Videos Common Errors and Solutions:

FileNotFoundError: Video file not found

• Explanation: This error occurs when one or more of the specified video file paths do not exist or are incorrect.
• Solution: Verify that all file paths in the video_paths parameter are correct and that the files exist at those locations.

ValueError: No frames were extracted from the video

• Explanation: This error indicates that the node was unable to extract frames from one or more of the input videos, possibly due to incompatible formats or corrupted files.
• Solution: Check the format and integrity of the input video files. Ensure they are not corrupted and are in a supported format. Re-encode the videos if necessary.
