Why do videos come to my messages very small in size

Hi iPhone-gramma,

If it was created on any type of networks, such as a cellular or other Internet service provider of the Wi-Fi, and the signal was not strong, then it may affect the quality.

There are a couple of things that we can try. The first if you are near her, she can AirDrop that to you. AirDrop would allow you to receive a larger file than Messages may be able to handle: How to use AirDrop on your iPhone or iPad - Apple Support

Another method is to try Mail Drop: Mail Drop limits - Apple Support

Either of these may help you get a higher quality video. Can you see if this helps?

Cheers!

Hi iPhone-gramma,

It's possible the person who sent the videos created the video in low quality. It may also depend on which network the person who sent the video is connected to.

We have additional information about sending videos with iMessages here: Send photos and videos in Messages on iPhone - Apple Support

Take care.
