Video background replacement questions.
What backgrounds can I use?
You can replace the keyed green screen with a solid color, a JPG, PNG, or WebP image, or an MP4 or WebM background video. The background file is selected after your source video is loaded.
Which source videos are supported?
The upload tool accepts MP4, MOV, and WebM videos up to 500MB. The source video needs a visible green screen for the Chroma Key replacement workflow.
Can I export a video with the new background?
Yes. Background replacement exports use the server H.264 MP4 workflow. The current export limit is 30 seconds; 720p is the free export tier, while 1080p uses Credits in five-second blocks.
Does background replacement use AI?
No. The standard workflow uses browser-first Chroma Key controls and composites the selected background behind the keyed subject. AI Enhance is a separate optional edge-cleanup path and is not required for background replacement.
Can I preview the background before exporting?
Yes. After you choose a solid color, image, or video background, the editor previews the composite and keeps the Chroma Key controls available for Strength, Edge, Spill Removal, and color picking.
Can I export a transparent video here?
This page is for replacing the background with a solid color, image, or video. For a transparent WebM export, use the Remove Green Screen tool instead.
