ComfyUI-PainterFrameMath

Aligns any input frame number to the nearest 4N+1 format (e.g., 120→121, 122→125), ensuring compatibility with video generation models that require specific frame count constraints.

Input

frame_number (INT): Input frame count from upstream node (force input)

Output

aligned_frame (INT): Frame count rounded up to nearest 4N+1 value

Example

Input: 120 → Output: 121
Input: 122 → Output: 125
Input: 124 → Output: 125
Input: 125 → Output: 125
