ComfyUI Node: Create Video from Path

Create Video from Path:

The "Create Video from Path" node is designed to help you transform a sequence of images into a cohesive video file. This node is particularly useful for AI artists who want to compile their generated images into a video format for easier viewing, sharing, or further processing. By specifying various parameters such as transition frames, image delay, and output settings, you can customize the video creation process to suit your specific needs. The node handles the complexities of video encoding and frame transitions, allowing you to focus on the creative aspects of your project.

Create Video from Path Input Parameters:

transition_frames

This parameter defines the number of frames used to create a smooth transition between consecutive images. Increasing the number of transition frames will result in a smoother transition but will also increase the video length. The default value is 10 frames.

image_delay_sec

This parameter sets the delay time in seconds for each image before transitioning to the next one. A higher value will make each image appear longer in the video. The default value is 10 seconds.

fps

Frames per second (fps) determine the frame rate of the video. A higher fps value results in a smoother video but may require more processing power and storage. The default value is 30 fps.

max_size

This parameter specifies the maximum size (in pixels) for the width or height of the images in the video. Images will be rescaled to fit within this size while maintaining their aspect ratio. The default value is 512 pixels.

input_path

The directory path where the input images are stored. The node will read images from this path to create the video. The default path is "./ComfyUI/input".

output_path

The directory path where the output video will be saved. The node will write the final video file to this location. The default path is "./ComfyUI/output".

filename

The name of the output video file without the extension. This allows you to specify a custom name for your video. The default filename is "morph".

codec

This parameter specifies the video codec to be used for encoding the video. Common codecs include "H264" and "XVID". The default codec is "H264".

Create Video from Path Output Parameters:

video_path

The path to the created video file. This output parameter provides the location of the video file generated by the node, allowing you to easily access and use the video in subsequent steps of your workflow.

Create Video from Path Usage Tips:

• Ensure that all images in the input directory are in the correct order, as the node will process them sequentially.
• Adjust the transition_frames and image_delay_sec parameters to achieve the desired pacing and smoothness in your video.
• Use a higher fps value for smoother videos, especially if your images contain a lot of motion or detail.
• Make sure the max_size parameter is set appropriately to avoid excessive resizing, which can degrade image quality.
• Verify that the specified codec is supported by your system and the intended playback devices.

Create Video from Path Common Errors and Solutions:

"Invalid video dimensions"

• Explanation: This error occurs when the width or height of the video is set to zero or a negative value.
• Solution: Ensure that the images in the input directory are valid and that the max_size parameter is set correctly to avoid resizing issues.

"Unable to create video at: <output_file>"

• Explanation: This error indicates that the node was unable to write the video file to the specified output path.
• Solution: Check the output directory permissions and ensure that there is enough disk space. Verify that the output_path and filename parameters are set correctly.

"Error resizing frame <i>: <error_message>"

• Explanation: This error occurs when there is an issue resizing a specific frame during the video creation process.
• Solution: Ensure that all input images are valid and not corrupted. Check the max_size parameter to make sure it is appropriate for the input images.

"Created video at: <output_file>"

• Explanation: This message indicates that the video was successfully created and saved to the specified output path.
• Solution: No action needed; the video creation process was successful.
