Introduction
This workflow uses Segment Anything v2 to segment out the part of the original video to be replaced. Then the Set Latent Noise Mask node is used before passing the VAE encoded video into the KSampler.
You will provide a reference image to be used with IPAdapter and also a prompt to guide the generation of the new object. The depth controlnet is used to give some guidance on what the shape of the replaced object should be.
