What is an Unscreen alternative for true-alpha video?
Unscreen's standalone video background-removal site has closed. If you still need a file with a real alpha channel—not a composited MP4—ExportAlpha removes the background with AI and then encodes VP9 WebM or ProRes 4444.
Export real alpha after AI removal
Upload a clip, download transparent WebM for Chrome, Firefox, and OBS, or ProRes 4444 for editors. New accounts get 5 free processing seconds.

What happened to Unscreen
Canva owns Unscreen. Canva's help article states that Unscreen.com has closed and that the team is focusing on Canva's own Video Background Remover. We are not restating subscription or credit rules beyond that notice—check Canva if you have leftover Unscreen files or license questions. Official page: Unscreen Officially Closed.
What to look for in an alternative
Background removal and alpha export are different steps. Many editors can erase a backdrop and then download a finished H.264 MP4 with a new scene already filled in. That is useful for social posts. It is not a transparent overlay file.
If you need the subject on a checkerboard—OBS stingers, web overlays, editorial handoff—you need a format that stores alpha. Everyday MP4 typically does not. See Does MP4 support a transparent background? and which format to export.
How ExportAlpha fits
ExportAlpha is a file-based Unscreen-style workflow, not a ranking and not a feature-for-feature clone:
- AI background removal on an uploaded clip
- Then a true-alpha encode: VP9 WebM (
yuva420p) or ProRes 4444 MOV - Upload limits: 60 seconds, 1080p, 200MB
- New accounts get 5 free processing seconds
It is not a live webcam filter, OBS plugin, or stream-keying tool. It does not ship HEVC-with-alpha; Safari still needs that format from another encoder. Product focus is WebM and ProRes. Details: WebM in Safari.
Canva and other editors
Canva currently points Unscreen visitors to its video editor and typically describes downloading a high-quality MP4 after background removal. That is a composited deliverable. If Canva or another editor later offers an alpha export in your account, use it—just verify the file with ffprobe or a timeline over a colored background before you call it transparent.
Where the WebM or ProRes goes next
- OBS overlay: Media Source / Browser Source
- OBS scene change: Stinger transition
- Editors: Import ProRes 4444, or convert an alpha-bearing MOV with FFmpeg
Frequently Asked Questions
What is an Unscreen alternative for true-alpha video?
Look for AI removal plus a real alpha export (WebM or ProRes 4444), not only a composited MP4. ExportAlpha is one such file-based tool. We do not claim it is the only option or a numbered ranking.
Does ExportAlpha replace Unscreen feature-for-feature?
No. We do not publish Unscreen price lists, plugin inventories, or score tables. The honest overlap is: upload a video, remove the background, download a file. The honest difference we care about is that ExportAlpha writes a real alpha channel in WebM or ProRes.
Is this a live webcam or stream-keying plugin?
No. Process a file, then place that file in OBS, a browser, or an editor. Live camera keying needs different software.
