Higgsfield turns a still image into motion with its preset camera moves — but image-to-video is exactly where generation artifacts hide: subjects morph mid-shot, faces and hands warp as the motion ramps, temporal flicker crawls across the frame, and a cloned twin drifts in when the model loses track of who's on screen. UploadCheck watches and listens to your Higgsfield export before you post, catches the frozen frames, loop seams, duplicated subjects, and audio-out-of-sync that a quick preview scroll misses, and hands your AI an exact fix list.
broken videos published. Every Higgsfield 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 Higgsfield — 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 Higgsfield generation" — the AI runs UploadCheck and reads back the findings. Free needs no key.
Export your video or audio from Higgsfield, 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 Higgsfield 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 Higgsfield as usual, then run the finished file through UploadCheck — from the web, the CLI, or your AI assistant. UploadCheck scans it for problems Higgsfield 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 Higgsfield generation — one check before you publish. It doesn't touch your Higgsfield project; it inspects the finished file and hands you (or your AI) a repair list.
Yes — Higgsfield's image-to-video renders are exactly what our AI oracle gates are built for. The free deterministic gates flag frozen and loop-seam frames (loop_freeze), audio desync (av_sync), and framing/format issues; the paid gates go further — twins catches a duplicated or morphed subject cloned across the shot, and our multimodal omni_watch and gemini_watch watchers actually see and hear the clip to surface warping, flicker, and 'this just looks wrong' artifacts, then report back what to fix. We don't claim to detect that a clip was AI-generated; we detect the visible and audible defects in the render so you don't ship them.
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.
