I try to send videos via text but my Google nexus 4 won't let me...why won't it let me??? Even if the video is only 10 seconds long it still says the file is too big to send
You're trying to send that vid as mms right? Some carrier limit the mms (audio/video) only 600kb max so i guess your video must be larger than that. You better call the carrier and what is the mms file size limit.
Or you can upload it somewhere privately (google drive) and share the link to your friend.
When the video camera is open, go into the settings menu and lower the resolution to the lowest setting. the quality will be lower, but you really can't MMS higher quality videos. You would need to use email for those. Most carrier limitations for MMS are at 600kbs.
