iMessage doesn't send HD video & if you include text it crashes!

Mine sends HD video with text.

 

I have issues sending pictures with text to people with iMessage... the Messages app just crashes. So I send the picture and then another message with the text and that works... It'll probably get fixed in the next update.

 

Mine hasn't kicked me out but it started loading the video and now it's just hanging halfway through and doing nothing.

Edit: right as I pressed post it suddenly in less than a second finished the last half and sent it.

Though I wonder if it may have something to do with type of iPhone? I'm running a 4, what is everyone else running that has responded to this.
