Kling's long clips and native audio look stunning on the preview loop, then fall apart on close inspection — a face that morphs mid-motion, hands that grow a sixth finger, a subtle temporal flicker, or lip movement that drifts off the generated voice track. UploadCheck watches and listens to every Kling export before you publish, catching the generation artifacts and audio desync that Kling's own preview hides.
broken videos published. Every Kling AI 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 Kling AI — 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 Kling AI generation" — the AI runs UploadCheck and reads back the findings. Free needs no key.
Export your video or audio from Kling AI, 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 Kling AI 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 Kling AI as usual, then run the finished file through UploadCheck — from the web, the CLI, or your AI assistant. UploadCheck scans it for problems Kling AI 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 Kling AI generation — one check before you publish. It doesn't touch your Kling AI project; it inspects the finished file and hands you (or your AI) a repair list.
Yes — Kling artifacts are exactly what the AI oracle gates are built for. The twins gate flags duplicated or morphed subjects across a scene (the classic cloned-face and warping problem on longer generations), av_sync catches lip and audio drift against Kling's native voice track, and loop_freeze catches the frozen seams that appear where an extend stitches. The omni_watch and gemini_watch multimodal gates watch and listen to the whole clip and describe what looks or sounds wrong, then hand your AI a timestamped fix list. Deterministic gates like loudness, dead_air, black_frames, and canvas_fill run free on every export.
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.
