This encrypted video file can only be converted into a video file that can be played by MP4 or other ordinary players after decryption. And can only be played by a dedicated player, and cannot be converted by other software.

For example, I know a golden diamond video encryption expert who uses the most advanced high-intensity encryption algorithm to encrypt video files frame by frame, and the encrypted video files are decrypted and played, thus preventing the encrypted video files from being cracked and extracted. Authorized encrypted videos can only be played on designated computers or mobile storage devices. I hope I can help you.
