How to Password Protect Large Video Files Online
Protecting a 10GB 4K video can be challenging for browser tools that try to load the entire file into memory. FileLocker uses browser storage and streaming APIs to process the video in smaller chunks instead.
FileLocker uses modern streaming technology and browser storage to process large files in smaller chunks. This can reduce memory pressure compared with loading the entire file into memory at once, although actual limits depend on the browser, device, available storage, and file.
Because FileLocker doesn't upload your video to a server over the internet, it works at the native read/write speed of your hard drive. Processing time depends on the file size, storage speed, browser, and device resources. Local processing avoids the need to upload the video to a remote server.
