Free 360° metadata & capture date tool
Fix Capture Dates and 360° Metadata in Photos and Videos
Check for missing GPano or spherical-video metadata, fix shifted capture dates from camera exports like Insta360, and download a corrected copy—directly in your browser with no re-encoding and no signup.
What Metadata Doctor changes
Metadata Doctor corrects the four XMP capture-date fields used in photos, updates QuickTime timestamps in MP4 and MOV files, and restores GPano or Spherical Video metadata. It does not recover deleted dates: if no trustworthy timestamp remains, you must enter the correct date manually.
| Photos | DateTimeOriginal, DateTimeDigitized, CreateDate, ModifyDate |
|---|---|
| Videos | QuickTime mvhd, tkhd, mdhd timestamps |
| 360° | GPano / Spherical Video V2 metadata |
| Does not | Recover a completely deleted date, or support INSV, OSV, or .360 files |

Pixels, timestamps, and instructions
Why do 360° files lose metadata or shift capture dates?
An equirectangular file stores the whole sphere as a stretched 2:1 rectangle. Separate GPano or spherical-video metadata tells compatible apps to wrap those pixels around an interactive sphere. If an editor or export pipeline strips that metadata, video players and photo galleries treat the file as an ordinary flat frame.
Similarly, exporting from camera apps like Insta360 often stamps the export timestamp into container headers rather than the original recording time, scattering your gallery out of order.
Common camera export scenarios
You exported a clip from Insta360 Studio or a 360 editor. The video is properly stitched, but YouTube shows a flat, stretched rectangle because spherical metadata was omitted, and Google Photos sorts it under today's date. Metadata Doctor fixes both issues locally without re-encoding.
What Metadata Doctor checks and fixes
Capture date fixer
Inspects embedded EXIF, XMP, and QuickTime headers, displays existing timestamps, and updates date fields across photos and videos.
Photo 360° metadata
Detects and injects equirectangular GPano XMP metadata into JPEG, PNG, and WebP panoramic photos.
Video 360° metadata
Detects and injects Spherical Video V2 (sv3d) metadata into supported MP4 and MOV containers without re-encoding.
Supported file types
Photos
JPEG (.jpg, .jpeg), PNG, and WebP. Repairs capture dates and adds full-frame equirectangular GPano metadata while preserving all other XMP data.
Videos
MP4 and MOV containers. Rewrites container atom headers (mvhd, tkhd, mdhd) and injects Spherical Video V2 without transcoding video streams.
Not supported: original GoPro .360 files, proprietary Insta360 .insv or DJI .osv raw files, non-equirectangular exports, stitching errors, or damaged media. Export or convert those files to standard MP4/JPEG before checking their metadata.
How it works
- 1 · Choose
Select one supported file
Drop it into the tool or open the keyboard-accessible file picker.
- 2 · Diagnose
Review metadata and dates
See embedded capture timestamps, spherical metadata status, and technical video/photo details.
- 3 · Repair
Download a corrected copy
Apply capture date corrections, add spherical metadata, or both, keeping your original untouched.
Privacy: your file stays in your browser
Inspection and repair run in a browser Web Worker with a Rust/WebAssembly module. Your photo or video contents are not uploaded to Mirame360. For corrected videos, supported browsers can stream the output directly to disk without storing gigabytes in RAM.
Common problems this check can clarify
- Insta360 camera export date shift: camera apps and editors write export time to container headers, breaking chronological photo and video sorting.
- MP4 appears flat on YouTube: the equirectangular pixels are present, but spherical-video metadata was lost during export.
- JPEG opens as a wide strip: the panoramic image has no GPano XMP for a compatible photo viewer to recognize.
- An editor removed metadata: saving a new copy preserved pixels while discarding the spherical instructions or capture dates.
Metadata Doctor FAQ
Why do Insta360 exports show the export date instead of the capture date?
Many 360° cameras and editing applications write the render timestamp to container creation headers when exporting MP4, MOV, or panoramic photos. As a result, media managers like Apple Photos or Google Photos sort exported files by the date they were edited rather than when they were recorded.
Can Metadata Doctor recover the original capture date automatically?
Metadata Doctor inspects embedded EXIF, XMP, and QuickTime container headers to show existing timestamps. If the export software stripped or overwrote the original recording date with the export time, you can enter the correct capture date and time manually.
Which photo and video date fields can it repair?
For photos (JPEG, PNG, WebP), it updates exif:DateTimeOriginal, exif:DateTimeDigitized, xmp:CreateDate, and xmp:ModifyDate in XMP. For videos (MP4, MOV), it updates creation and modification timestamps in supported mvhd, tkhd, and mdhd QuickTime container atom headers.
Does fixing an MP4 or MOV timestamp re-encode the video?
No. The tool rewrites container header boxes directly in your browser using a Web Worker and WebAssembly. It does not decode or re-encode video or audio streams, preserving 100% of original visual quality.
Can it fix capture dates and spherical metadata together?
Yes. You can correct the capture date, inject missing equirectangular GPano or Spherical Video V2 metadata, or apply both corrections simultaneously in a single downloaded copy.
Does it support INSV, OSV or GoPro .360 files?
No. Metadata Doctor supports standard JPEG, PNG, and WebP photos, plus MP4 and MOV videos. Proprietary dual-fisheye or multi-track camera formats like Insta360 .insv, DJI .osv, or GoPro .360 must first be exported to standard panoramic files.
Why does my 360 video appear flat on YouTube?
YouTube needs spherical-video metadata to recognize an equirectangular MP4 or MOV as interactive 360° content. If that metadata is missing, the player displays the file as a flat, stretched rectangular video.
What is GPano and Spherical Video metadata?
GPano is XMP metadata that tells photo viewers how to wrap panoramic pixels around a sphere. Spherical Video V2 (sv3d) is the MP4/MOV container structure used by video platforms and browsers to enable interactive 360° navigation.
Does Metadata Doctor upload my file?
No. Your file contents stay entirely in your browser and are processed locally by a Web Worker using WebAssembly. Files are never uploaded to Mirame360 servers.
Will it fix an incorrectly exported or non-equirectangular video?
No. Adding metadata cannot fix stitching flaws, wrong projections, non-equirectangular frames, or corrupted media. Ensure your media is a correctly stitched equirectangular panorama before adding metadata.
Do I need a Mirame360 account?
No. Checking files, repairing metadata, correcting capture dates, and downloading corrected copies is free and does not require an account.
Need a deeper metadata workflow?
Use the open-source command-line tool for local automation, or read the technical guide before troubleshooting an export.
Ready to make the panorama interactive?
Once the source and metadata are correct, upload it to Mirame360 to host, view, and share the 360° experience on the web.
