Check Project
Check Project is a pre-show validation report. Before you go live it scans the whole project and flags anything that commonly causes problems on stage — missing files, mixed audio sample rates, codec pitfalls — so you can fix them while there is still time.
Open it from the Header menu (☰) → Check Project. The report recomputes every time you open the modal, so it always reflects the current project state; use Re-check to refresh it after making changes.
New in 3.2.
The Report
A summary banner at the top states the overall result and how many clips were checked. Below it, each check appears as its own block with a severity, a short summary, an optional recommendation, and a list of the affected items.
| Severity | Meaning |
|---|---|
| 🟢 OK | Nothing to do for this check |
| 🔵 Info | Worth knowing, no action required |
| 🟠 Warning | Likely to cause trouble — review before the show |
| 🔴 Error | Will break playback — fix before going live |
What It Checks
| Check | Severity when it triggers | What it means |
|---|---|---|
| Missing media files | 🔴 Error | One or more clips reference a file that can't be found. Re-link or restore the media. |
| Mixed audio sample rates | 🟠 Warning | The project mixes several audio sample rates. Standardise on one rate and set the output device / ASIO driver to match. |
| Non-HAP video files | 🟠 Warning | Video clips use a codec outside the HAP family, which may not decode on the GPU. Consider transcoding to HAP for reliable 4K+ playback. |
| HAP block alignment | 🟠 Warning | HAP clip dimensions are not a multiple of 4. HAP encodes in 4×4 blocks, so unaligned dimensions can cause edge artefacts — re-export at aligned dimensions. |
| NDI sources present | 🟠 Warning | The project depends on live NDI sources. Confirm the senders are online and reachable before the show. |
| Empty compositions / tracks | 🔵 Info | Compositions or tracks contain no clips — usually harmless, but often a sign of leftover scaffolding. |
A clean project shows every check as OK with a "Project looks good" summary.
