RoadGuard-Dashcam EvidenceTool

Have you ever witnessed a traffic violation but couldn't capture a clear license plate?
Did you see a violation on the road and couldn't find the right tools to manage the footage?

RoadGuard is a specially designed tool for safe drivers and road users to accurately capture clear images from any video (dashcam or mobile) and automatically add timestamp information, easily generating authoritative evidence screenshots.

【Core Features】
🔍 Magnification Mode: Swipe to zoom in on any area of the video instantly, making license plates, faces, and vehicles visible.
✂️ Selective Screenshot: Drag to select the area you want, and the saved image contains only the selected video content, free from mobile status bar (time, battery) and app buttons, providing a clean image ready for submission.
🕐 Enhanced Watermark: Automatically overlays four layers of information to significantly enhance evidence effectiveness:
• Date and Time of the screenshot (system clock)
• Video playback point (timestamp)
• Custom violation label (user-input)
• Evidence tool: RoadGuard
🎬 Clip Extraction: Set start and end points on the progress bar to quickly extract violation clips and save them, with small size and lossless quality for easy upload.
⏩ Variable Speed Playback: Support multiple playback speed adjustments for slow-motion confirmation of key moments; long-press the fast-forward button for continuous skipping, easily bypassing unimportant segments.
⏭ Frame-by-Frame Navigation: Precise navigation to the previous/next frame, ensuring you don’t miss any critical moments.
🗜 Video Compression: One-click compression to below a specified size (default 80MB), handled directly on the device, allowing for upload to regulatory or police station systems.
🔇 Sound Removal: Outputs a silent version of the video, protecting passenger privacy for safer uploads.
🔄 Vertical Video Rotation: Easily rotate vertical videos (portrait or special-angle dashcams) 90° to fill the landscape screen perfectly. Screenshots reflect the rotated view accurately.
💡 Usage Tip: Most vertical videos should be right rotated (clockwise); this ensures the screenshot stored in the gallery aligns with typical display conventions. If your video is shot with an inverted or special-angle lens, consider left rotation instead, always checking that the screen view is correct before capturing screenshots.

【Who Is It For?】
• Drivers who want to report violations.
• Users needing to keep dashcam footage as evidence.
• Any road user concerned about driving safety.

【Privacy Assurance】
All video and screenshot processing are done locally, ensuring your privacy is fully protected without uploading to any server.

【Usage Disclaimer】
This tool is intended solely for legal evidence collection, reporting traffic violations and preserving accident proof. Please do not use this tool for unauthorized recording, invasion of privacy or any unlawful acts. Users bear all legal responsibilities.
