Hello angelitafromgoodyear,
Thank you for using Apple Support Communities. It's my understanding that when trying to send videos via iMessage, the message will either take longer than expected or fail. I can see how this could be concerning as you're able to send videos to Android users without issue. I'm happy to help.

Restart your iPhone, iPad, or iPod touch
If the issue persists, see if the issue occurs on cellular data and Wi-Fi networks. Take a look at the look below for additional steps:
If you can't send or receive messages on your iPhone, iPad, or iPod touch
If the behavior continues, tell us if this occurs with multiple contacts and on multiple networks. Please include any other troubleshooting steps you may have tried.
Have great day!
