Unable to send MP4 through message

Why I am unable to send MP4 through a message on my Mac. I get not delivered. But... if I convert to the same MP4 video file using any converting software it solves the problem. Could be because of the MP4 generated by AI or any other source? The info about the video source looks the same.


Thanks.

iMac 27″ 5K, macOS 10.13

Greetings Girshon Rutstein,


It sounds like when sending an MP4 through Messages you are getting Not Delivered. We know how important this is for you, and we will help get you to the right place for answers.


The first thing to try is the steps listed in this support article. These steps can often resolve this type of issue:

If you can’t send or receive messages on your Mac - Apple Support


It could also be incompatible format support in the MP4 file. If you are using the Compressor app, then this article on MPEG-4 settings in Compressor might provide some insight. When you are converting the file, it sounds like it possibly changes it to a compatible MP4 format.


Cheers!
