Downloaded Eufy video events won’t trim or send through iMessage

A couple issues. When downloading an event video to my camera roll on ios, i can’t trim the video, or send it through iMessage. When trimming, it gets stuck on saving, or says unable to load. When sending through imessage, it takes forever to send and eventually times out and says message failed to send.
I know theres no direct iMessage share option (dumb) so i download then send through iMessage.

Both of my 2C cameras have pixelated bars and strips that randomly pop up. Video quality on both 2C’s is very blurry and smudgey. Protective film was removed.
