Let’s talk about the results first. Only about 1/3 of the entire recording of an important seminar is left. Although Party A settled the payment in the end, to me it was a serious mistake that could never be made up for. **

What happened

The previous workflow was roughly like this. After shooting on location, use the iPad to copy the materials from the SD card to the SSD hard drive. After returning home, copy the materials again to the NAS before editing.

The problem this time lies in the step of copying to SSD. In fact, the day before this accident, there was already a problem when copying the materials after work. When copying, it showed that the copy was completed, and the thumbnails were also displayed. I also clicked on a few to play them, and there was no problem. But when the SSD was connected to the computer again, the file size was displayed fine, but the thumbnails were no longer displayed. Most of the files could not be opened. Only one or two files could be played for a few seconds and then froze, and the player jumped to the next one. At that time, my first reaction was that it might be caused by a problem with the contact between the iPad and the SSD, and then I asked my partner to send it to me again through the network disk. I didn’t even think about the SSD being broken.

The same workflow was still used on the day of the seminar, but because there was other work the next morning, the materials on the SSD were not processed in any way. I formatted the SD card early the next morning at the filming location…

When the material could not be imported into the software during editing, I realized that there might be a problem with the hard drive. Immediately find a friend to introduce someone to perform hard drive data recovery. After a night of trouble, the technician said that the file was not written to the hard disk at all and could not be restored.

The bigger problem is that there are still projects on the SSD that are being edited but have not yet been delivered.

Reflection

  • Dual-camera shooting, try not to stop the camera in the middle of important meetings. The main machine position must ensure that there are dual card slots, and two cards can be written at the same time. In important scenes, try not to shut down both cameras. This way, even if there is a problem with one machine, the secondary camera is still protected. Before the shooting started, my partner asked me if I needed to shoot the entire scene, and I said “no”. -Be sure to check whether the power supply, storage, recording and other equipment are working properly before the official shooting. You must have a correct attitude. One of the main reasons for this accident was my contempt for photography. I have done this job many times, and any thought such as simple requirements for this job will lead to serious consequences.
  • Dual channel backup. Be sure to back up the material directly from the SD card to 2 hard drives. In my original process, the SSD hard drive was the key to the entire process. Once there was a problem with the SSD, it would lead to catastrophic consequences.
  • Be sure to follow the prescribed workflow. No matter how late you work overtime, all procedures must be followed according to regulations. If the card is not cleared when you back up to the NAS at night, there is still a way to recover.

In short, an accident is a combination of several small mistakes that lead to an irreversible accident. Finally, an SD card was installed on the main machine, and 2 new SSDs and mobile hard drives were purchased, specifically for backup of unfinished projects. I hope similar problems like this won’t happen again in the future.
