Transparent-export fixes. If you export with a transparent background, update to this version.

Fixed

  • Transparent export formats appeared not to work. The formats labelled "(transparent)" — MOV · ProRes 4444, MKV · FFV1 and PNG sequence — only keep transparency that the background already has; picking one didn't make the background transparent. With the default gradient (or a colour or image background) still behind the recording, the export came out solid, so the transparent option looked broken.
    • Choosing a transparent format while the background is solid now shows "Background isn't transparent" in the editor header with a one-click Make transparent button (keeps the chosen format).
    • Verified with real exports through the app: MOV (ProRes 4444 XQ, yuva444p12le), MKV (FFV1, bgra) and PNG sequence all carry a true alpha channel — areas outside the recording and its shadow are fully transparent.
  • Transparent background exported as solid black. Setting Background → Transparent while the export format was MP4 (the default) silently flattened the background to black, with only a small header warning.
    • Turning the background transparent now switches the export to MOV · ProRes 4444 automatically.
    • Exporting a transparent background as MP4 or regular WebM now asks for confirmation first, explaining that the background will be black and which formats keep transparency.
  • Couldn't tell what would be transparent. The editor preview showed transparent areas as dark grey. It now shows a checkerboard behind transparent areas (preview only — not exported).
  • Outdated note in the Background panel claiming WebM can't be transparent.

Added

  • WebM · VP9 (transparent) export format — VP9 with a real alpha channel (alpha_mode=1). Plays with transparency in Chrome, Edge, OBS, web pages and most editors, making it the easiest transparent format to preview. Quality presets apply.

Notes

  • Windows' built-in video players often display a MOV's transparent areas as black even though the file is transparent. Check MOV exports in DaVinci Resolve, Premiere Pro, After Effects or OBS — or export WebM (transparent) and open it in Chrome.
  • In Frame mode the recording grows to fill the whole canvas while zoomed, so there's no transparent margin during zooms (by design). Use Video mode to keep the transparent margin throughout.

Downloads: ZoomArc.Setup.0.12.1.exe is the installer; ZoomArc.0.12.1.exe is the portable version (no install needed). Windows 10 2004 or newer, 64-bit. Full history: CHANGELOG.md
