Ditch the green screens and expensive studio rentals.

How to Change Video Backgrounds in 3 Simple Steps
Auto-Extract Subject
Upload your video to the ChatCanvas. Lovart's MCoT engine analyzes motion and depth to instantly isolate your subject from the most cluttered backgrounds. No manual rotoscoping required.
Generate Custom Scenes
Say goodbye to cheesy stock templates. Prompt the agent to create breathtaking, hyper-realistic custom backgrounds using elite models like Nano Banana Pro, perfectly tailored to your brand.
Harmonize & Export
Use semantic Touch Edit to adjust lighting, shadows, and color grading so your subject naturally belongs in the new environment. Upscale the final composite to 4K and export for your campaigns.
The Ultimate AI Toolkit for Video Background Replacement
Green-Screen-Free Matting
Achieve flawless edge detection even with flying hair, complex motion, or motion blur. Lovart intelligently tracks subjects across frames, separating them from any environment.
Lighting & Shadow Harmonization
Stop subjects from looking like 'stickers'. Use Lovart's Touch Edit to command natural adjustments, matching your subject's color grading and shadows to the newly generated scene.
Infinite Scene Generation
Bridge the gap between video editing and AI image generation. Create any background imaginable directly on the ChatCanvas without ever hunting for stock footage again.
Multi-Modal Direction
Push your creative boundaries. Use your newly background-changed videos as references in Seedance 2.0 to orchestrate completely new cinematic sequences with synchronized audio.
4K Broadcast Upscaling
Ensure your content meets premium agency standards. Use Lovart's built-in Upscale feature to enhance your final video composite to crystal-clear 4K resolution.
Omni-Channel Export
Format your videos precisely for where they will live. Export the fully composited scene as a 9:16 vertical video for TikTok/Reels, or a 16:9 cinematic cut for YouTube.
Marketers Scaling Campaigns with Lovart's Video Changer
“We used to spend $5k a month renting studios to shoot TikTok ads. Now, creators film in their living rooms, and we use Lovart to change the video background to custom, high-end 3D sets. It's indistinguishable from real life and saves us a fortune.”

“Changing video backgrounds was always a nightmare because of hair and clothing edges. Lovart's MCoT engine extracts the models perfectly. I then prompt the AI to place them on a minimalist runway. Our conversion rate jumped 22%.”
Elena R.

“The ability to change a scene without a green screen is absolute magic. I shot an actor in a garage and used Lovart to swap the background for a cyberpunk city generated by Nano Banana Pro. The lighting matched flawlessly. A true game-changer.”
