Show HN: AI Video Detector – check whether a video may be AI-generated

Evidence Lab for Social Video launched an AI Video Detector that analyzes public social video links or uploaded files to determine if a video may be AI-generated. The tool provides likelihood-based results with explanations of suspicious signals, confidence levels, and limitations, helping users decide whether to pause and seek human review.

Source/media access Waiting for the analyzer to confirm source and media access. Pending PendingEvidence Lab for Social Video Check public social video links or upload the original video file for deeper AI-video screening. When public media is accessible, the report can include video signals; when access is limited, upload is the most reliable path. AI video check Public TikTok and X/Twitter links are in beta when accessible. Instagram and YouTube links may return limited link scans. Upload the original file for the most reliable frame, motion, and timeline analysis. Option 1 Best-effort for supported public social video URLs. If public media is unavailable, upload the original video for deeper analysis. Option 2 Use upload when you need the strongest available frame, motion, and timeline analysis. By clicking Check video link , you confirm you have the right to submit this video link for analysis and understand results are likelihood-based, not proof. Estimated credits depend on video size and duration. Detected platform: Unknown . Live analysis process Follow the analysis pipeline below the detector. Progress is stage-based and evidence scores are only shown for signals that can be checked. Check progress Step 0 of 6Paste a public video link or upload a video you have the right to analyze.

The formal six signal groups appear in the completed result below. Source/media access Waiting for the analyzer to confirm source and media access. Pending PendingVisual artifact signals Numeric scores appear only after visual evidence is actually sampled. Pending PendingMotion/temporal consistency Numeric scores appear only after temporal checks complete. Pending PendingCompression/encoding patterns Numeric scores appear only after compression and encoding checks complete. Pending PendingAudio-video consistency Numeric scores appear only when audio/video evidence is available. Pending PendingSource detail signals Source detail checks appear only when media or source metadata is available. Pending PendingWhy it helps Some videos look real at first glance. Then something feels off: the face moves strangely, the hands blur, the audio feels inconsistent with the clip, or the clip appears during a breaking news event with no clear source. AI Video Detector gives you a quick way to slow down. Paste a social video link first. If the link cannot be checked, you will see a clear reason and a safer next step. The report explains suspicious signals, confidence level, and limits, so you are not left with a black-box answer. The result helps you decide whether to pause, look for the original source, compare other uploads, or ask for human review. Private, deleted, restricted, or unavailable videos are not silently treated as real or fake. You get a plain explanation. Supported links Public links are checked on a best-effort basis.

Check this platform →Evidence report A report can include AI likelihood, confidence level, visual signals, motion signals, audio-video consistency when available, source/media access signals, unchecked signals, and recommended next steps. Free reports include a basic audio technical check when audio is readable. Paid reports add bounded audio-motion consistency windows for a deeper evidence review. Sample full video report Full video scanA full scan keeps the score, confidence, signals, limitations, and next steps visually separated so the report is easier to read. Free reports include a basic audio technical check when audio is readable. Paid reports add bounded audio-motion consistency windows for a deeper evidence review. AI likelihood 62/100 Checked signals suggest possible AI generation or manipulation. Confidence Medium Based on media access and signal quality. Timeline highlights 00:04–00:11 · face-edge texture inconsistency 00:12–00:18 · hand motion flicker 00:21–00:28 · compression lowers reliability Source and media details Duration, size, and source context were reviewed when available. Sampled visual evidence Visual signals such as faces, hands, edges, texture, and compression artifacts. Motion consistency Temporal flicker, warping, repeated movement, and scene-to-scene consistency. Audio-video consistency Basic audio technical checks run when readable audio is available; paid reports add bounded audio-motion timing windows. Platform-private context Private analytics, account ownership, and platform-internal labels are not available. Sample limited link report Limited link scanWhen a public link cannot expose enough video media, the page shows a limited report and pushes upload as the next best action. AI likelihood Not enough media No numeric score when video media is unavailable. Confidence Low Frame, motion, and audio/video signals were not checked. Public link/source signals The public URL shape, platform, and accessible source details were reviewed. Media resolver attempt The public link did not provide enough accessible media for a full video scan. Sampled visual evidence No original visual evidence was available from this link in the scan. Motion and timeline analysis Timeline sections require accessible video media or an uploaded original file. Audio-video consistency Audio-video consistency cannot be checked without readable audio and accessible media. Workflow Start with a public link when available. For the strongest report, upload the original video file. If the link is private, deleted, restricted, or unavailable, we explain the problem instead of showing a misleading score.

FAQ An AI video detector is a tool that checks whether a video may show signs of AI generation, deepfake editing, or other manipulation. AI Video Detector supports public social link checks with platform limits and original video uploads for deeper review. Try a public social video link or upload the original video file, run the check, and review the evidence report. Link scans depend on public media access; uploads provide the strongest available review. Yes, for supported public links when the video can be safely accessed. Some links return limited public-link signals only; upload the original video for deeper analysis. Yes. Compression, edits, reposts, low quality, short clips, missing audio, and partial AI editing can all affect results. Treat the report as a screening aid. No. The report does not prove a video is fake or real. It shows signals and confidence so you can decide whether more review is needed. Yes, when readable audio is available. Free reports include a basic audio technical check for audio presence, duration alignment, silence, clipping, and level stability. Paid reports add bounded audio-motion timing windows. We do not use speech transcription, voice-clone detection, lip-sync verification, or semantic matching in the current lightweight scanner. Some videos have no readable audio, muted audio, restricted media access, or platform-transcoded audio that cannot be sampled reliably. When audio is unavailable, the report marks the signal as not checked and does not treat it as low risk.
