5.6 Repairing Damaged Video Files<br />

5<br />

Backup, Deletion <strong>and</strong> Repair<br />

If the computer has been shut down improperly, e.g. due to power failure, use this function to repair the<br />

damaged video files.<br />

Tip: When a computer has been shut down improperly, the first thing you do before starting the<br />

GV-<strong>System</strong> is to run Repair Database Utility. After running the Utility, go back to ViewLog <strong>and</strong> view<br />

Video Events. You should be able to play back all video files at this step. However, if what you see is<br />

a question mark after clicking on the file, the problem may be that the recording process was<br />

interrupted. To repair the file, run the AVI Repair Utility <strong>and</strong> follow the steps below.<br />

1. Double-click AVIRepairAPI.exe in the GV folder. This dialog box appears.<br />

Figure 5-9<br />

2. Click the Browse button to find the damaged video file.<br />

3. If you know the codec <strong>and</strong> resolution of the file, select <strong>Manual</strong>, select Compression Type <strong>and</strong><br />

type Resolution. Alternatively, you may select Auto <strong>and</strong> the system will run all combinations for<br />

you. Please note it takes longer time to repair with this selection.<br />

4. Click the Repair button to start.<br />
