Generate preview thumbnails for every vMix input over the network. Single .exe, zero configuration, just start and go.
⬇ Download for Windows · Part of Directors Plan
Both tools use the vMix SnapshotInput API and support all input types. The difference is speed, reliability, and how inputs are identified:
| vmix-snapshot-proxy | DP Thumbnail Server | |
|---|---|---|
| Identification | By input number only — breaks when inputs are reordered | By key/UUID — stable across reordering |
| Speed | Slow, often unreliable | Fast — optimized 320×180 thumbnails with ffmpeg |
| Thumbnail size | Full resolution (~200–500 KB) | Optimized ~10 KB per thumbnail (with ffmpeg) |
| Setup | Command line arguments | Zero config — auto-detects vMix |
| Interface | Basic input list | Visual web UI with grid, auto-refresh, right-click menu |
| Configuration | Edit CLI flags | Browser-based settings |
| Dependencies | Node.js required | None — single .exe (ffmpeg optional for resize) |
| Legacy support | — | /{number}.jpg still works for existing integrations |
