Dashcam Metadata Integrity Audit
Budget: $50 – $0 USD
I have a one-minute dash-cam clip and need a forensic eye on its metadata and visual cadence. The goal is to confirm whether the file has been edited in any way—especially if someone has slipped frames out or in, rewritten the timestamps, or manipulated the embedded GPS trail.
What stands out for me is the speed overlay. It looks like it may have been added after the fact rather than captured by the camera itself, so I’m specifically looking for proof that the overlay is not native to the original recording.
Here is what I expect from your review:
• A concise report outlining the complete metadata you extract (ExifTool, FFprobe, or comparable utilities are fine) and whether the date-and-time stamps are sequential and untampered.
• Confirmation that no frames have been removed, duplicated, or inserted—frame-hash analysis or similar evidence will help.
• Verification that the GPS stream, if present, is genuine and consistent with the timestamps.
• A clear verdict on the speed overlay: native or post-production, with your technical reasoning.
• Any supporting logs or sidecar files produced by your tools.
The footage is short, so turnaround can be quick, but accuracy is everything. If you have prior experience with video forensics or digital chain-of-custody work, that will be a plus.
