Video Background Remover: Make Any Video Transparent
Remove the background from a clip of up to 60 seconds with BiRefNet v2 and download a transparent WebM with a real alpha channel — 4 credits, no green screen required.
How Video Background Remover works
- 01
Upload your clip
Add the video you want to isolate. The subject can be a person, product, or object filmed on any background — you don't need a green screen or a controlled studio set.
- 02
Run BiRefNet v2
The BiRefNet v2 video matting model separates your subject from the background frame by frame, tracing edges like hair and fingers without a fixed color key.
- 03
Get a transparent WebM
Download a WebM file with a true alpha channel for 4 credits. Everything behind your subject is fully transparent, ready to drop onto another layer.
- 04
Overlay on any background
Composite your cut-out subject over a new image, video, or color in your editor — or keep generating in Viralance to build the full scene.
Why creators use it
- Outputs a transparent WebM with a real alpha channel, so the background is fully removed rather than replaced with a solid color
- Works without a green screen — BiRefNet v2 separates the subject by shape, not by a fixed chroma color
- Costs 4 credits per video, billed from your one-time credit balance with no subscription
- Handles fine edges like hair and thin objects through per-frame video matting
- Lets you overlay the isolated subject on any new background, video layer, or color in your editor
- Pairs with Viralance's other AI models to build complete short-form scenes from one cut-out subject
Use cases
- Cut a creator or spokesperson out of a clip and overlay them on branded backgrounds for TikTok, Reels, and Shorts
- Isolate a product from its filmed setting and place it on clean or seasonal backdrops for e-commerce videos
- Replace a messy or distracting background without setting up a physical green screen
- Build transparent video overlays and lower-thirds to composite into larger edits
Frequently asked questions
How do I remove the background from a video without a green screen?
Upload your clip to Viralance's Video Background Remover, which runs the BiRefNet v2 video matting model. It separates your subject from the background by shape and edges rather than a chroma color, so you don't need a green screen. The result is a transparent WebM with an alpha channel for 4 credits.
What file format does the transparent video come out as?
The output is a WebM file that includes a true alpha channel. The alpha channel stores the transparency, so the area behind your subject is empty rather than filled with a solid color. You can import the WebM into a video editor and layer it over any background.
How much does it cost to remove a video background on Viralance?
Each video background removal costs 4 credits. Credits come from one-time packages — Viralance has no subscription, so you only spend the 4 credits when you actually process a clip.
Is an AI video background remover better than chroma key green screen?
They solve the problem differently. Green screen chroma key removes a specific color, which requires even lighting and a clean backdrop. BiRefNet v2 uses AI matting to detect the subject's shape frame by frame, so it can isolate footage shot on ordinary backgrounds without a colored screen.
Can I put my subject on a different background after removing the original one?
Yes. Because the export is a transparent WebM with an alpha channel, the background is genuinely gone. You can overlay the subject on any image, video, or color layer in your editor, or keep building the scene with Viralance's other AI models.
Does the tool handle hair and fine edges in a video?
BiRefNet v2 is a video matting model that traces the subject's edges per frame, including detail like hair strands and thin objects, instead of cutting along a single hard color boundary the way basic chroma key does.
What kinds of videos work with the background remover?
It works on clips with a clear foreground subject — a person talking, a product demo, or an object in motion — filmed on any background. Upload the video, run BiRefNet v2, and download the transparent WebM to composite elsewhere.
