Analyze image1,It contains a sequence of animation frames arranged in a grid.Return the result in JSON format.
Create a high-quality animate sprite sheet based on the image2,notice the weapon are in all frames,notice the character's size should be the same in all frames.
CRITICAL INSTRUCTIONS:
1. The layout,grid structure,and poses MUST EXACTLY match the first image (the template sprite sheet) need pure white background.
2. DO NOT STRETCH the sprites. Maintain the original internal aspect ratio of the characters.
3. If the output aspect ratio differs from the template, add padding (empty space) rather than stretching the content.
4. Apply the character's appearance (colors, clothing, features) to the poses in the template.
