ScreenSage ProExport Transparent Video
A transparent video keeps the transparent areas of the frame so you can layer it over other footage in an editor. By default, exports have no alpha channel; turn on Keep transparency in Export Settings. In the interface, it's the Transparency row in Export Settings (⌥⌘E), available only when the codec is HEVC or ProRes 4444.
1. Choose a codec that supports alpha
- HEVC: small files; the recommended choice. With transparency on, it exports as "With alpha · MOV".
- ProRes 4444: much larger files, for post-production workflows that need maximum compatibility and quality.
H.264 and ProRes 422 can't carry an alpha channel. Transparent videos are always saved as MOV.
2. Turn on Keep transparency
After you check Keep transparency, the summary at the bottom shows "With alpha".
If the background fills the frame, the panel warns that the export won't show any transparency. Click Use Transparent Background to remove the background and keep only the recording, its shadow and rounded corners.
3. Check the result
Import the MOV into your editor and place it over a colored layer to confirm the edges, shadow and corners look right. Some players show transparent areas as black; that doesn't mean the alpha channel is missing.
Most upload platforms, browsers and chat apps don't keep the alpha channel. For direct viewing, export a separate MP4 with a background.
