Frequently Asked Questions
What is TrackCrop?
TrackCrop is the core feature of 4GoCheck. It allows you to select a region in your dashcam video (like a license plate), and the app will automatically track that region throughout the video and extract it with perspective correction applied.
Is my video uploaded to a server?
No. All video processing is done entirely on your device. Your videos are never uploaded, stored, or transmitted to any server. Your privacy is our priority.
What video formats are supported?
4GoCheck supports most common video formats including MP4, MOV, and other formats commonly used by dashcams.
Why is processing slow on my device?
Video processing is computationally intensive. Processing speed depends on your device's performance, video resolution, and video length. For best results, try processing shorter clips.
Can I use this for legal evidence?
While 4GoCheck can help you extract and enhance video regions, we cannot guarantee the accuracy of processing results. Please consult with legal professionals regarding the use of processed videos as evidence.
Does it work offline?
Yes! 4GoCheck works 100% offline. No internet connection is required to process your videos.
