GreenScreenRemover
Transparent Video for Unity
Convert green screen footage to WebM with VP8 alpha channel — the format Unity and Unreal Engine need for transparent video overlays in games.
VP8 vs VP9 — Which Codec for Your Game Engine?
VP8 (Recommended for Unity)
- +Native alpha channel support in Unity Video Player
- +Faster decoding — lower CPU overhead during gameplay
- +Widest compatibility across Unity versions (5.6+)
- −Larger file sizes compared to VP9
VP9 (Smaller Files)
- +30–50% smaller file sizes than VP8
- +Better quality at lower bitrates
- −Higher decode cost — may impact frame rate
- −Limited alpha support in some Unity versions
Recommendation: Use VP8 for Unity projects. The decode performance and broad compatibility outweigh the larger file size. Use VP9 only when file size is critical and you have confirmed alpha support in your target Unity version.
Game Engine Compatibility
Unity
Import WebM VP8 directly. Use the Video Player component with materialOverride or Render Texture for transparent overlays on UI or world-space canvases.
Unreal Engine
Use Media Framework with WebM files. Create a Media Texture and apply it to a material with alpha blending for transparent video playback in-game.
Godot & Other Engines
WebM VP8 with alpha is the standard format for transparent video across game engines. Godot supports it natively via the VideoStreamPlayer node.
How It Works
From green screen footage to game-ready transparent video in three steps.
Upload Green Screen Footage
Upload video recorded against green, blue, or any solid color background.
AI Background Removal
The chroma key engine removes the background and generates an alpha channel for every frame.
Export WebM VP8 Alpha
Download as WebM with VP8 or VP9 codec. Import into Unity, Unreal Engine, or Godot and start using it.
Common Use Cases in Game Development
Cutscenes & Cinematics
Overlay live-action actors on game environments for hybrid cinematics. Transparent video lets you composite real footage into 3D scenes.
UI & HUD Elements
Use transparent video for animated UI elements, loading screens, or character portraits that blend seamlessly with the game interface.
VFX & Particle Effects
Record real-world effects (fire, smoke, explosions) on a colored backdrop, remove the background, and use them as transparent video textures. An alternative to sprite sheets from video.
Streaming Overlays
Create transparent video overlays for OBS, Streamlabs, or in-engine streaming setups. Perfect for animated alerts, transitions, and branded elements.
Create Game-Ready Transparent Video
Upload green screen footage and export WebM VP8 with alpha channel for Unity, Unreal Engine, or any game engine.
