What Hidden Metadata Is Stored Inside a QuickTime .MOV File?
Apple's QuickTime File Format (.MOV, major brand qt ) stores richer hardware and software telemetry than standard ISO MP4 files. When recorded on an iPhone or exported from Final Cut Pro, DaVinci Resolve, or Premiere Pro, a .MOV file embeds key-value dictionaries inside its moov/meta/keys and moov/udta boxes:
- Exact GPS Coordinates (
com.apple.quicktime.location.ISO6709): Latitude, longitude, and elevation down to a few meters of where the video was filmed. - Device & OS Fingerprints:
com.apple.quicktime.make,com.apple.quicktime.model,com.apple.quicktime.software, and lens focal telemetry. - Desktop NLE Project Paths & XMP Packets (
uuid): Adobe Premiere, After Effects, and DaVinci Resolve timeline identifiers and local disk paths.

Frequently Asked Questions
Does an iPhone .MOV video contain my exact GPS location?
Yes, if Camera Location Services were on when recording. UploadCorrect detects and strips com.apple.quicktime.location.ISO6709 and ©xyz GPS atoms completely.
Will cleaning a .MOV file wash out iPhone HDR colors or flip my vertical video sideways?
No. UploadCorrect preserves your video stream's colr HDR transfer parameters and tkhd portrait rotation matrix while scrubbing only the non-essential metadata boxes.
Are my .MOV files uploaded to a cloud server?
Never. All QuickTime inspection and lossless binary stream copying happen 100% locally inside your web browser.
