Course Introduction

Many students have learned to replicate 10-second AI product promotion short videos, but they don't know how to make long videos!

This issue's hardcore content: complete 1:1 replication practice of a 45-second product promotion long video, with people, backgrounds, and desktop products all custom-replaced, while the original video's actions, camera movement, and rhythm are fully preserved.

✅Tools used: Infinite Canvas, Wanxiang 3.0

✅Core solution: crop the benchmark video to integer frames -> segment generation -> unify lighting and color -> seamless stitching in CapCut

✅Reusable: set up the workflow once, then only replace the reference video, people, and product images to produce product promotion materials in batches

⚠️Note: suitable for secondary replication of e-commerce product promotion materials, only for your own compliant materials, do not misappropriate others' original videos!

Suitable for all e-commerce sellers, short video operators, and product promotion bloggers. No live shooting and no model search needed, enabling low-cost rapid mass production of product promotion videos.
