Video Texting issues

My NetVue bird feeder camera is taking great video and I’m able to download them and watch them on my phone in both the NetVue app and the camera roll, but when I try to send them via text message they always fail to send.

Dear Valued User,
We apologize for any inconvenience you may have encountered. Could you please provide us with the model and system version of your phone? We will forward this matter to our engineers for prompt resolution.
Best regards,
The Netvue Team.
