ComfyUI AI Image/Video Detection Guide
Original ComfyUI files may keep platform names, C2PA, XMP/EXIF, MP4/MOV metadata, SEI markers, file-name patterns, or video frame watermarks. Upload the direct platform download whenever possible.
Signals to Check
The browser version reads source signals preserved in the original file instead of judging only by pixels. Video files add container metadata, SEI markers, file-name hints, and sampled frame watermark checks.
- workflow JSON: ComfyUI
- PNG tEXt: ComfyUI
- nodes: ComfyUI
- frame export: ComfyUI
Limits
Social-media transcoding, screenshots, screen recordings, editing exports, and metadata cleaners can remove many signals. No signal found does not prove the file is human-made.
Privacy and Performance
Images and videos are analyzed locally in the browser. Video frame extraction lazy-loads ffmpeg.wasm and can take longer for large files.
