ComfyUI Node: Loop Image Sequence

Loop Image Sequence:

The JWLoopImageSequence node is designed to manage and manipulate sequences of images by adjusting the number of frames in the sequence to match a specified target. This node is particularly useful for AI artists who work with animations or image sequences and need to ensure that their sequences have a consistent number of frames. The node can either truncate the sequence if it has more frames than needed or loop the sequence to extend it if it has fewer frames. This ensures that the final sequence has the exact number of frames required, making it easier to work with in subsequent processing steps.

Loop Image Sequence Input Parameters:

images

This parameter expects a sequence of images in the form of a tensor. The images are the input sequence that you want to adjust to match the target number of frames. The quality and content of the images will directly impact the final output sequence.

target_frames

This integer parameter specifies the desired number of frames in the output sequence. The default value is 16, and you can adjust it in steps of 1. If the input sequence has more frames than this target, the sequence will be truncated. If it has fewer frames, the sequence will be looped to reach the target number of frames.

Loop Image Sequence Output Parameters:

images

The output is a sequence of images in the form of a tensor, adjusted to match the specified target number of frames. This output sequence will have the exact number of frames as specified by the target_frames parameter, either by truncating the original sequence or looping it.

Loop Image Sequence Usage Tips:

• To ensure smooth looping, make sure the input sequence has a natural flow from the last frame back to the first frame.
• Use the target_frames parameter to match the frame count required by your animation or video project.
• If you need to extend a very short sequence, consider the visual impact of looping and whether it creates noticeable repetitions.

Loop Image Sequence Common Errors and Solutions:

"AssertionError: len(images) == target_frames"

• Explanation: This error occurs if the final length of the image sequence does not match the target number of frames.
• Solution: Ensure that the target_frames parameter is set correctly and that the input sequence is properly formatted. Double-check the input sequence length and the logic for looping or truncating the sequence.
