Please advise how to make a password on the video mp4 file in the LGK3 Smartphone so that the fille cannot be opened without password. Thank you.

You'll need some sort of app to do that.  Here's one that claims to do it.  I've never used it so can't remark how well it works.  https://play.google.com/store/apps/details?id=com.newsoftwares.folderlock_v1&hl=en

You can lock the file with filelocker app: https://play.google.com/store/apps/details?id=com.mwgo.filelocker

You can also hide the file altogether with leo privacy guard. where the file will go in to leo guard app and can only be accessed by entering a password : https://play.google.com/store/apps/details?id=com.leo.appmaster&hl=en

Question I have is .... why isnt the phone itself in a locked state good enough?

The file would not be accessed when the phone is locked. I have a number pad lock on my phone and it can take up to 10 digits. It would take a long time to try them to get into my phone if my phone was ever lost. Including 0000000000 through 9999999999 I have 10 Billion different up to 10 digit pin codes that I can use.

Hopefully the MP4 is not anything illegal. As for only purpose to go beyond complexity of 10 billion different pin codes would be if its something so secret that 10 billion is not enough of a wall to keep law enforcement or government from someday up to 10 billion tries later from getting access to.

Sometime friends borrow phone (for whatever reason) and invade your privacy by checking photos and videos. Maybe he is asking this to protect himself from that

I never loan my phone out...

I don't lend my phone to anyone either. My rule is If you have an emergency, I will call for you. If you need to text someone, I will send the text. But no one puts their hands on my phone but me. Call me paranoid, but I don't trust anyone with it.
