Transparent Video in DaVinci Resolve: Free Magic Mask Alternative
Blackmagic Design's DaVinci Resolve is widely celebrated as the industry's most generous free video editor and color grading suite. However, its most coveted AI feature — Magic Mask (neural rotoscoping for people and objects) — is strictly locked behind the paid DaVinci Resolve Studio license ($295 USD). If you use the free version of DaVinci Resolve, here is how to achieve transparent video compositing without paying $295.
No $295 Studio License Required
Isolate foreground subjects with CutoutVideo and drop transparent footage straight into DaVinci Resolve.
Try CutoutVideo (Free) →Option 1: Drag & Drop Transparent WebM (Edit Page)
Modern releases of DaVinci Resolve (v18.5 and v19+) on both macOS and Windows have built-in support for decoding WebM containers with VP9 alpha transparency:
- Upload your clip to CutoutVideo and click Download Transparent WebM (.webm).
- Open DaVinci Resolve and navigate to the Edit workspace page.
- Import the downloaded
.webmfile into your Media Pool. - Place your background footage on Video Track 1.
- Drag the transparent
.webmvideo onto Video Track 2 directly above track 1. - Instant transparency! The background is already isolated. Open the Inspector panel on the top right to adjust Transform, Cropping, Composite Mode, or Opacity without touching node trees.
Option 2: Green-Screen MP4 + 3D Keyer (Color Page)
If you prefer grading with an uncompressed key in DaVinci's legendary node editor:
- Download the Green-Screen MP4 file from CutoutVideo.
- Place it on Video Track 2 above your background video in the Edit timeline.
- Switch to the Color workspace page at the bottom of the screen.
- In the Node Editor area, right-click on the blank canvas and select Add Alpha Output. A blue circular terminal will appear on the far right edge of the node graph.
- In the central palette dock, select the Qualifier icon (the eyedropper) and change the qualifier mode dropdown from
HSLto 3D. - Click and drag a line across the green background in the main viewer to sample the green color space.
- Click the Invert icon (the black-and-white circle next to the qualifier tools) so the green background is keyed out while your subject remains visible.
- Click and drag the blue square output of your grade node to the blue circular Alpha Output terminal on the right.
- Return to the Edit page: your green screen is completely keyed out, displaying your background video underneath.
