This is a copy from a post earlier but explains my problem to a t…videos are 15-25 seconds long
I can not send video clips via messaging from the Blink app on my iPhone or iPad either. Further if I save the video to the iPhone or iPad, it will still not send via messaging. This occurs over both home WiFi and cell network.
After saving the video to my iPhone or iPad, I can email the video. The playback on my laptop after saving the video from the email is hit or miss also. Sometimes it plays, sometimes it doesn’t. Almost like there is a naming or encoding problem for the video.
