The DJI MAVIC drone fell into the river, and the last video was damaged. See the file properties for the following information: the video format is MOV, and the size is 1.8GB. The following are the steps to successfully repair the H.265 (HEVC) encoded MOV video of the DJI unloading drone:
1. Determine whether the data code is empty
Use the high compression ratio of the compression software to compress the video file. If there is basically no difference in size before and after compression, it means that the underlying code is not empty, and you can proceed to the next step.
2. Determine whether the video file header is normal
Use the code checking software to open the file code, as shown in the figure below, the file header is normal, and the video repair operation can be performed.
3. Find video shooting parameter reference repair
It is not difficult to find out from the video parameters that the video encoding is HEVC, the video pixel is 3840x2160, that is, 4K resolution, the frame rate is 29.97, and the bit rate is 100M. Through these key parameters, the damaged video is repaired accordingly, and the video File repaired successfully.
