ComfyUI Node: 🗍 Frame Set Merger

Frame Set Merger [DVB]:

The Frame Set Merger node is designed to combine two sets of video frames into a single cohesive frame set. This node is particularly useful when you have two different frame sets that you want to merge, either to create a continuous sequence or to blend different video sources. The node allows you to specify which frame set should take priority in the merging process, ensuring that the most important frames are preserved. This functionality is essential for video editing and AI-generated video content, where seamless transitions and coherent frame sequences are crucial. By using this node, you can efficiently manage and merge frame sets, enhancing the overall quality and fluidity of your video projects.

Frame Set Merger [DVB] Input Parameters:

a

This parameter represents the first frame set to be merged. It is a required input and should be of the type FrameSet. The frames in this set will be considered for merging based on the specified priority.

b

This parameter represents the second frame set to be merged. It is also a required input and should be of the type FrameSet. The frames in this set will be considered for merging based on the specified priority.

priority

This parameter determines which frame set should be given priority during the merging process. It accepts two options: use_a_when_possible and use_b_when_possible. If use_a_when_possible is selected, frames from the first frame set (a) will be prioritized. Conversely, if use_b_when_possible is selected, frames from the second frame set (b) will be prioritized. This parameter ensures that the most important frames are preserved according to your preference.

Frame Set Merger [DVB] Output Parameters:

frames

The output parameter frames is a merged frame set of type FrameSet. This merged frame set combines the frames from the input frame sets (a and b) based on the specified priority. The resulting frame set maintains a consistent framerate and provides a seamless sequence of frames for further processing or rendering.

Frame Set Merger [DVB] Usage Tips:

• Ensure that both input frame sets (a and b) have the same framerate to avoid errors during the merging process.
• Use the priority parameter to control which frame set's frames should be prioritized in the merged output, depending on the importance of the content in each frame set.
• This node is particularly useful for creating smooth transitions between different video clips or for blending frames from different sources to create a cohesive video sequence.

Frame Set Merger [DVB] Common Errors and Solutions:

Frame sets have different framerate {a.framerate} and {b.framerate} - cannot merge!

• Explanation: This error occurs when the two input frame sets have different framerates, which makes it impossible to merge them into a single frame set.
• Solution: Ensure that both input frame sets (a and b) have the same framerate before attempting to merge them. You can use a frame rate conversion node to align the framerates if necessary.
