ComfyUI Node: WanImageToVideo (Flow2)

WanImageToVideo (Flow2):

The WanImageToVideo_F2 node is designed to facilitate the conversion of images into video format, providing a seamless transition between a start and an optional end image. This node is particularly beneficial for AI artists looking to create smooth video sequences from static images, leveraging advanced encoding and decoding techniques to ensure high-quality output. By utilizing this node, you can generate videos that maintain the visual integrity of the original images while offering flexibility in terms of video length and resolution. The node's primary function is to handle the interpolation between images, ensuring a coherent and visually appealing video output.

WanImageToVideo (Flow2) Input Parameters:

images

This parameter represents the collection of images that will be used to create the video. The images are processed to ensure they are suitable for video conversion, with the node handling any necessary adjustments to maintain quality. The input should be a sequence of images that you wish to convert into a video format.

start_percent

The start_percent parameter determines the starting point of the image sequence to be used in the video. It is a float value ranging from 0.00 to 1.00, with a default of 0.00, indicating the beginning of the sequence. Adjusting this value allows you to skip a portion of the initial images, focusing the video on a specific segment of the sequence.

end_percent

Similar to start_percent, the end_percent parameter specifies the endpoint of the image sequence for the video. It also ranges from 0.00 to 1.00, with a default of 1.00, indicating the end of the sequence. By modifying this value, you can truncate the sequence, effectively shortening the video to include only the desired portion of the images.

WanImageToVideo (Flow2) Output Parameters:

IMAGE

The output of the WanImageToVideo_F2 node is a video file generated from the input images. This video maintains the visual quality of the original images and reflects any adjustments made through the input parameters. The output video is ready for further processing or direct use, providing a smooth transition between the start and end images.

WanImageToVideo (Flow2) Usage Tips:

• To create a video that focuses on a specific part of your image sequence, adjust the start_percent and end_percent parameters to define the exact segment you want to include.
• Ensure that your input images are of high quality and consistent resolution to achieve the best video output, as the node will upscale or downscale images to match the desired video dimensions.

WanImageToVideo (Flow2) Common Errors and Solutions:

"Invalid image sequence"

• Explanation: This error occurs when the input images are not in a compatible format or are missing.
• Solution: Verify that all input images are correctly formatted and accessible. Ensure that the image sequence is complete and properly ordered.

"Start or end percent out of range"

• Explanation: This error indicates that the start_percent or end_percent values are outside the acceptable range of 0.00 to 1.00.
• Solution: Adjust the start_percent and end_percent values to fall within the specified range, ensuring they are set between 0.00 and 1.00.

"Device not found"

• Explanation: This error may occur if the node is unable to access the necessary computational resources for processing.
• Solution: Check your system's hardware configuration and ensure that the required devices, such as GPUs, are properly installed and recognized by the software.
