ComfyUI Node: Append Reversed Frames

Append Reversed Frames:

The JNodes_AppendReversedFrames node is designed to enhance your media processing workflow by appending a reversed sequence of frames to your original set of images. This node is particularly useful for creating looping animations or effects where a seamless transition between the end and the beginning of a sequence is desired. By reversing the frames and optionally removing the first or last frame of the reversed sequence, you can achieve a smooth and continuous playback effect. This node simplifies the process of creating such effects, saving you time and effort in manual editing.

Append Reversed Frames Input Parameters:

images

This parameter expects a sequence of images (frames) that you want to process. The images should be in a format compatible with the node, typically as a list or array of image objects. The node will take this sequence and append a reversed version of it to the end, creating a mirrored effect.

remove_head

This is a boolean parameter that determines whether the first frame of the reversed sequence should be removed. If set to True, the first frame of the reversed sequence will be excluded from the final output, which can help in creating a smoother transition. The default value is False.

remove_tail

This is a boolean parameter that determines whether the last frame of the reversed sequence should be removed. If set to True, the last frame of the reversed sequence will be excluded from the final output, which can help in avoiding duplicate frames and creating a smoother transition. The default value is False.

Append Reversed Frames Output Parameters:

IMAGE

The output is a single sequence of images that includes the original frames followed by the reversed frames. This combined sequence can be used directly in your media projects to create looping animations or other effects that benefit from a mirrored playback.

Append Reversed Frames Usage Tips:

• To create a seamless looping animation, consider setting both remove_head and remove_tail to True to avoid duplicate frames at the transition points.
• Use this node in conjunction with other media processing nodes to enhance your workflow and achieve more complex effects.
• Experiment with different sequences of images to see how the reversed frames affect the overall animation.

Append Reversed Frames Common Errors and Solutions:

"Input images not provided"

• Explanation: This error occurs when the images parameter is empty or not provided.
• Solution: Ensure that you provide a valid sequence of images to the images parameter before executing the node.

"Invalid image format"

• Explanation: This error occurs when the images provided are not in a compatible format.
• Solution: Verify that the images are in a format supported by the node, typically as a list or array of image objects.

"Unexpected error during frame reversal"

• Explanation: This error occurs if there is an issue during the reversal process, possibly due to corrupted image data.
• Solution: Check the integrity of your input images and ensure they are not corrupted. If the problem persists, try using a different set of images.
