Dream Machine's diffusion renders look stunning at a glance, then fall apart on the second watch: a face that morphs mid-shot, background detail that boils and flickers frame to frame, a hand that grows a sixth finger, or a loop whose seam jumps. UploadCheck watches every exported clip frame by frame and catches these generation artifacts — warping, temporal inconsistency, cloned subjects, audio desync, and broken loops — before you post them.
broken videos published. Every Luma AI (Dream Machine) generation 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 Luma AI (Dream Machine) — 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 Luma AI (Dream Machine) generation" — the AI runs UploadCheck and reads back the findings. Free needs no key.
Export your video or audio from Luma AI (Dream Machine), 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 Luma AI (Dream Machine) generation 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 generate and export your generation in Luma AI (Dream Machine) as usual, then run the finished file through UploadCheck — from the web, the CLI, or your AI assistant. UploadCheck scans it for problems Luma AI (Dream Machine) can't check, returns timestamped flags and fixes, and you re-check until it passes.
Morphing and warped motion, temporal flicker, frozen/looped frames, cloned or duplicated subjects across a shot, audio that drifts out of sync with the video, off-target loudness, and wrong resolution/codec/frame-rate — each with the exact timestamp and a fix.
No. UploadCheck is the last step after your Luma AI (Dream Machine) generation — one check before you publish. It doesn't touch your Luma AI (Dream Machine) project; it inspects the finished file and hands you (or your AI) a repair list.
UploadCheck doesn't reject a clip for being AI-generated — it inspects what's actually on the frames. Deterministic gates catch loop seams and freezes (loop_freeze), audio-to-motion desync (av_sync), and framing/letterbox problems (canvas_fill), while the paid AI oracle gates go further: twins flags a subject that morphs or clones itself across a scene, and the omni_watch and gemini_watch multimodal watchers see and hear the clip to flag the "something looks wrong" artifacts — boiling texture, warped anatomy, temporal instability — that Dream Machine's diffusion pipeline is prone to, then tell your AI exactly what to fix.
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 generation before publish saves the re-generate/re-export, re-upload, and the reputational hit of a broken clip going live.
