ComfyUI Workflow for Animated Videos -- 2

I am seeking an expert in ComfyUI to create a custom workflow - blending animated product videos/png sequence with AI-generated environments. The goal is to integrate 3D rendered product animation into a custom environment, incorporating three seamless camera motions: pan and tilt, dolly in/out, and orbit around the product. It is crucial to preserve the original product video details, including maintaining the original resolution, retaining colors, and keeping exact dimensions. I need to be able to scale & position the product video into the environment. Additionally, I want to ensure the generated environment can be reused for multiple product videos.

Key Requirements:
- Expertise in creating workflows using ComfyUI
- Ability to integrate 3D rendered animated product videos into a background environment.
- Generate and implement camera motions: pan and tilt, dolly in/out, and orbit on the final video.
- Preserve original product video details without alteration
- Ensure the generated environment is reusable for different product videos

Ideal Skills and Experience:
- Proficiency in ComfyUI and workflow creation
- Attention to detail in preserving video quality and product specifications

I look forward to collaborating with a skilled professional to bring this project to life.
