Demo summary

The video shows the 'Replace Background' feature in OpenArt VFX, which automatically swaps a street background for a cinematic studio look using a reference image without requiring manual mask selection.

Step-by-step

Upload the reference video to the editor
Navigate to the Replace Background section below the video
Select a reference background from the presets or upload a custom image
Generate the video to apply the seamless background swap

Options

Use preset backgrounds like Clean Creator Studio, Luxury Penthouse, or Golden Hour Beach
Upload background images from local files
Select background images from previous creations or favorites

Watch out for

The model automatically masks the subject, so manual mask selection is not available for this specific tool

Tips

Use a screenshot of a video frame to generate your background image to ensure perspective and composition remain accurate
If your reference image includes a subject, keep them in the scene when recreating the background for better alignment
Use GPT Image 2 or similar tools to recreate specific cinematic looks for your background

Highlights

“there is no need to mask. The model knows you want to replace the background, and that's it.”
