Final Cut Pro renders a clean timeline, but the delivery file is what ships — and that's where black frames at the head, a stray loudness spike, captions crashing the title-safe area, or an audio track that drifts out of sync slip through. UploadCheck scans your exported master before it hits YouTube and catches the spec problems the FCP viewer never flags.
broken videos published. Every Final Cut Pro export gets one final pass, so a frozen frame or dropped word never reaches your audience.
instead of re-watching a 20-minute export. UploadCheck finds the one bad moment with its exact timestamp — no more scrubbing to hunt for it.
saved off every delivery. No re-export → re-upload → "why is there a black frame at 0:14" from a client after it went live.
It doesn't replace Final Cut Pro — it's the automated final QC pass on the finished export, the thing an editor can't reliably do by eye.
Same engine every way. The free scan runs 35 automated checks; a paid plan adds the AI gates (garbled speech, on-screen continuity, narration match) and lifts the hourly limit.
Use Claude Code, Codex, Cursor, or any LLM for production? Paste our one-time setup prompt and it wires a /check command. Then just say "check my Final Cut Pro export" — the AI runs UploadCheck and reads back the findings. Free needs no key.
Export your video or audio from Final Cut Pro, then drop the file into the free scan. No account, no tools — a real PASS / BLOCK verdict with timestamps in seconds.
Start free →On a paid plan, upload the Final Cut Pro export straight into your UploadCheck dashboard — same engine as the free scan, with every AI gate on and no hourly throttle. Paste a link or choose a file.
See paid plans →You edit and export your export in Final Cut Pro as usual, then run the finished file through UploadCheck — from the web, the CLI, or your AI assistant. UploadCheck scans it for problems Final Cut Pro can't check, returns timestamped flags and fixes, and you re-check until it passes.
Frozen or black frames, looped/reused footage, dead air and audio dropouts, garbled or unintelligible speech, captions outside the platform-safe area, low-contrast text, loudness off the platform target, and wrong resolution/codec/frame-rate — each with the exact timestamp and a fix.
No. UploadCheck is the last step after your Final Cut Pro export — one check before you publish. It doesn't touch your Final Cut Pro project; it inspects the finished file and hands you (or your AI) a repair list.
Does UploadCheck replace Final Cut Pro's built-in loudness meters and validation? No — it's a second, independent pass on the actual exported file. FCP's viewer shows you the timeline; UploadCheck inspects the rendered master the way a platform ingest server or broadcaster QC would, so a caption that sits fine in the FCP canvas but crosses the title-safe boundary in the delivery, or a head black frame introduced on export, gets caught before you publish rather than after.
Instead of re-watching a clip to hunt for the one bad moment — or worse, finding it after you've published — UploadCheck flags it in one pass with the exact timestamp. Catching one bad export before publish saves the re-generate/re-export, re-upload, and the reputational hit of a broken clip going live.
