Video help

[Ian Freeman]

I filmed my daughter walking and tried to send it through WhatsApp to my mum gslaxys4, dad galaxys4mini and also my wife galaxys5 . But the video does not work and comes up with an error 'video had been removed from your phone because it contained unsafe content. Sent it to my brother in his iPhone 6 and it worked.
What could it be? A virus? Or their phones not upto date?

If I shoot a video through WhatsApp and send it it works that way
