Why Standard Operating Systems Hide Video Metadata
When you right-click a video file on Windows and select Properties > Details, or inspect a video in macOS Finder using Get Info, you only see high-level display attributes: duration, frame resolution (e.g. 1080×1920), total bitrate, and audio sample rate.
Operating systems conceal the deep binary architecture of the media container. However, when you upload a video to platforms like TikTok, Instagram Reels, YouTube Shorts, or Facebook, platform ingestion engines run automated binary parsers that dissect the file header in milliseconds.
Our free Video Metadata Checker gives creators the exact same diagnostic visibility that platform algorithms have, letting you see every hidden stamp, tag, and marker before you publish.
What Our Free Forensic Checker Analyzes
Container Brand (ftyp)
Detects whether your video is formatted as an Apple QuickTime (qt ) mobile camera file or a generic desktop export (isom / mp42).
Encoder Software Tags
Flags identifying stamps left behind by CapCut, Adobe Premiere, FFmpeg (Lavf), DaVinci Resolve, HandBrake, or web converters.
C2PA AI Provenance
Scans for JUMBF metadata boxes and cryptographic manifests embedded by AI video tools (OpenAI Sora, Kling, Runway, Midjourney).
Perceptual Hash (pHash)
Calculates the visual frame hash automated platform moderation systems use to identify duplicate, cross-posted, or unoriginal creatives.
SHA-256 Binary Checksum
Computes the cryptographic checksum of the entire file. Uploading files with identical checksums across accounts triggers duplicate flags.
GPS & Device Atoms
Inspects user data boxes (udta) for embedded camera serial numbers, lens models, shutter telemetry, and GPS location coordinates.

How to Check Your Video Metadata for Free
- Select or Drop Your Video: Open the UploadCorrect Video Inspector. Drag and drop any
.mp4or.movvideo file from your phone or computer. - Instant Client-Side Scan: Within 1 second, our binary parsing engine evaluates the file header directly in your browser. You will see a comprehensive diagnostic breakdown with an overall Suppression Risk score.
- Evaluate the Red Flags: Review the check cards to see if your file contains generic Linux encoder tags, CapCut stamps, duplicate hashes, or AI provenance markers.
- Optional 1-Click Sanitization: If red flags are detected, you can immediately sanitize the container and format it with clean Apple iPhone (Clean QuickTime Profile) QuickTime camera metadata for £1.99.
Checking Video Metadata via Command-Line (For Developers)
If you are comfortable using the terminal, you can also inspect metadata locally using open-source command-line utilities:
Using FFprobe:
ffprobe -v quiet -show_format -show_streams -print_format json input.mp4
This outputs the format tags, encoder strings, and stream parameters. Look specifically under format.tags.encoder to see if your file was stamped by Lavf or CapCut.
Using ExifTool:
exiftool -G -a input.mp4
ExifTool parses QuickTime user data atoms (udta), XMP tags, and embedded GPS coordinates. Note that ExifTool is a diagnostic reader—stripping atoms with ExifTool can sometimes corrupt MP4 moov atom offsets.
Frequently Asked Questions
Can social media platforms see what software I used to edit my video?
Yes. Video container headers explicitly declare encoder strings, editing software versions, and custom metadata atoms unless specifically stripped before upload.
What is a perceptual hash (pHash) and why does it matter?
A perceptual hash is a visual fingerprint generated from the luminance and frequency structure of video frames. Unlike file checksums, perceptual hashes remain similar even if a video is slightly compressed or resized. Social platforms use them to detect duplicate and recycled content.
Does inspecting my video modify or compress it?
No. The metadata inspection is 100% read-only. Your original file is never altered, converted, or compressed during the check.
What should I do if the checker flags red flags?
If the checker identifies CapCut stamps, Linux encoder strings, or duplicate perceptual hashes, you can use our 1-click cleaner to strip those atoms and format your file with clean Apple iPhone (Clean QuickTime Profile) QuickTime camera telemetry for £1.99.
Is there a file size limit for checking?
You can inspect video files up to 2GB directly in your browser. Because processing runs locally on your machine, inspection takes under a second regardless of internet speed.
Does this work on mobile phones?
Yes. The inspector works seamlessly in Safari on iOS (iPhone/iPad) and Chrome on Android without needing to download any app.
