Reporting something: every run writes a log, and Settings › About has the button that opens it along with the one that copies your system information. Attach both to an issue and the report arrives with everything it needs. The last ten runs are kept, so yesterday's is still there; nothing is ever sent anywhere on its own.

System requirements:
Concat runs everything on your machine, so the hardware sets the ceiling. The minimum column is what a build will run on at all; the recommended column is what makes 1080p editing feel smooth and keeps 4K exports and captions from being a wait.
| Minimum | Recommended | |
|---|---|---|
| CPU | Any 64-bit processor from 2013 or later | 6 cores or more |
| GPU | None. Without a usable GPU the window and monitor fall back to the CPU | Any GPU with Metal (macOS), DirectX 12 (Windows) or Vulkan (Linux) |
| RAM | 4 GB | 16 GB for 4K timelines and the larger caption models |
| Storage | 500 MB for the app and the smallest caption model | 2 GB for every optional model, plus room for projects and exports |
Optional models download from the settings panel on first use and then never need the network again: auto-captions 78 MB to 488 MB depending on the whisper size you pick, text-to-speech 132 MB or 349 MB, person cutout 15 MB, object cutout 179 MB, and the cutout brush 40 MB.
Important
The best way to contribute is to grab a build from the Releases page and use it: find where it breaks, and say where it could be better.
