Dashcam Images: How to Judge Useful Footage

Motion, low light, windshield dirt, focus, compression and reflections can all remove detail. Inspect several consecutive frames before deciding whether an object is genuinely unreadable.

No. Distance, relative speed, angle, glare and lighting can defeat even a high-resolution camera, so resolution alone is not a guarantee.

Preserve the original clip first, then use the camera app or a video player to export a frame. Avoid overwriting or editing the only copy of important footage.

A wider view captures more context but can make distant details smaller and introduce edge distortion. Choose a field of view that balances scene coverage with useful detail.
