Video Vault App: How It Differs From a Photo Vault

Phone steps follow Apple and Google help pages, and menu names differ by version. Mac steps use macOS 14 and later names.

Why video is harder to protect than photos

A photo is one small file. A video is large, and a player reads it in a stream while you watch. A vault that encrypts the file on disk must still hand readable data to the player. How it does that decides whether a readable copy appears on your device.

• Playback. An app can decode a video in memory, or it can write a readable temporary file and play that. You can test which.
• Preview frames. A thumbnail or poster frame is a still photo of the video. It needs the same care as any photo.
• Space. Importing makes a copy. You need free space for both copies until you delete the original.
• Backups. Large files take time to back up, and a backup may hold the original you forgot to delete.

Built-in ways to hide videos

You may not need a vault app. Apple and Google both include a hiding tool that covers videos.

• iPhone and iPad. In Photos, press and hold the video, tap Hide and confirm. Open it later under Collections, Utilities, Hidden. Face ID or Touch ID unlocks the album.
• Mac. In Photos, Control-click the video and choose Hide Photo. View it with View > Show Hidden Photo Album. Touch ID or your login password unlocks it.
• Android. Locked Folder in Google Photos holds photos and videos. It uses your device screen lock.

Full steps for each are in how to hide photos. The same limits apply to videos: the lock is your device unlock, and with iCloud Photos Apple says hidden items are hidden on your other devices too, not removed from your library. For a deeper look at Mac photo and video storage see the photo vault guide.

Where a video vault can leak

Test a video vault on your Mac

The hands-on vault test walks through a full check. For video, add one extra step. Use a short, harmless clip. Play it in the app for a few seconds, then run this in Terminal to list files above 1 MB that changed in the last 15 minutes in your temporary folder:

find "$TMPDIR" -type f -size +1M -mmin -15 2>/dev/null

No output means no large recent file there. It does not prove the app is safe, because an app can write elsewhere. The full test checks the app's own folders, Spotlight and Time Machine as well.

Original or converted: a choice to make on import

Some vault apps convert a video to a smaller format when you import it. That saves space, but it changes the file. Keep the original until you have opened the converted copy and seen that it plays from start to end. If the video matters, choose the option that keeps the file byte for byte.

Five questions for any video vault

1. Does it play the video from memory, or does it write a readable file first?
2. Does it keep the original or convert it?
3. Can you export the video back out, and does the export play?
4. Where does it back up large files, and are they encrypted before they leave your device?
5. What happens to the vault if you delete the app?

Phone videos and a Mac vault

Most video vault apps are phone apps. A Mac app does not protect files on your phone. To use a Mac vault for phone videos you must copy them to the Mac first, check that the copy plays, and then delete the phone copy and its Recently Deleted entry yourself. Do that only for videos you are sure you want to move.
