i message wont let me sent videos. tried everything

If you can't send or receive messages on your iPhone or iPad - Apple Support

If you can't send or receive photos and videos in messages

Make sure that your device has enough space to receive images and videos.

If you use SMS or MMS messaging to send photos or videos, your carrier may set size limits for attachments. Larger files may take more time to send, and your iPhone can compress photo and video attachments when necessary. If you experience an issue when you try to send full size images, you can manually send lower quality images:

1. In the Settings app, tap Messages.
2. Tap Low Quality Image Mode.

Can’t send videos to non I Phone uses. Tried restarting my phone, turning I message on/off.

iMessage doesn't enter into this issue.

The first thing you need to do is check with your carrier and make sure that you have MMS enabled on your account. You also need to have an active cellular data connection.
