Matters needing attention in video storage of mobile phone

Need to choose reliable storage media, such as hard disk, U disk or CD. Ensure the good quality and performance of storage media to avoid data loss or damage. Select appropriate storage formats, such as MP4 and AVI, to maintain the integrity and quality of video. Depending on different devices and operating systems, different storage formats may be supported, which needs to be selected according to the actual situation.

In order to prevent data loss or damage, it is recommended to back up the video regularly. You can use cloud storage service or other backup tools for automatic backup, or you can manually copy video files to other storage media. If the video contains personal privacy information, such as face recognition information, measures such as encryption should be taken to protect it. You can use encryption software or the built-in encryption function of the operating system to encrypt and protect video files.
