ComfyUI Node: 🔗 Frame Set Append

Frame Set Append [DVB]:

The Frame Set Append [DVB] node is designed to seamlessly concatenate two frame sets, allowing you to create a continuous sequence of frames from two separate sets. This node is particularly useful when you need to merge different video segments or animations into a single cohesive frame set. By specifying an offset and step, you can control the precise positioning and indexing of the appended frames, ensuring smooth transitions and consistent frame rates. This node is essential for video editing and animation workflows where combining multiple frame sets is required.

Frame Set Append [DVB] Input Parameters:

a

This parameter represents the first frame set that you want to append. It is the primary frame set to which the second frame set will be added. The frame set should be of the type FrameSet.TYPE_NAME.

b

This parameter represents the second frame set that you want to append to the first frame set. It should also be of the type FrameSet.TYPE_NAME. The frames from this set will be reindexed and appended to the first frame set.

offset_from_end

This integer parameter specifies the offset from the end of the first frame set where the second frame set should start. The default value is 0, meaning the second frame set will start immediately after the first. You can adjust this value to create a gap or overlap between the two frame sets.

step

This integer parameter defines the step size for reindexing the frames in the second frame set. The default value is 1, and the minimum value is also 1. This parameter allows you to control the indexing interval of the appended frames, which can be useful for creating specific frame sequences.

Frame Set Append [DVB] Output Parameters:

frames

This output parameter is the resulting frame set after the concatenation of the two input frame sets. It is of the type FrameSet.TYPE_NAME. The output frame set will have a continuous sequence of frames from both input sets, reindexed according to the specified offset and step.

Frame Set Append [DVB] Usage Tips:

• Ensure that both input frame sets have the same frame rate to avoid errors and ensure smooth transitions.
• Use the offset_from_end parameter to create intentional gaps or overlaps between the two frame sets for creative effects.
• Adjust the step parameter to control the indexing of the appended frames, which can be useful for creating specific animation effects or sequences.

Frame Set Append [DVB] Common Errors and Solutions:

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

• Explanation: This error occurs when the two input frame sets have different frame rates, which prevents them from being concatenated.
• Solution: Ensure that both input frame sets have the same frame rate before attempting to concatenate them. You may need to adjust the frame rate of one of the frame sets to match the other.
