My friend sent me a video but the quality is terrible?

So my friend has an IPhone. I'm not sure what type but it's for sure a newer type. I have a Samsung Galaxy. They showed me a video on their phone with perfect quality and perfect sound, and I wanted it. So they sent it to me, and the sound is good but the quality of the footage is terrible. It's EXTREMELY blurry and I can't see properly in it at all.
I really need this video. They tried sending it again but it just comes up the same way. What should I do?

Did they send it attached to a message? They might have turned on the "Low Quality Image Mode" option.

The original file wasn't sent then. If they sent it in a message or Facebook it's likely it was compressed to a smaller size, sacrificing quality for a smaller file size.

They'll have to upload the file to a file sharing site like 4shared where the upload will not be compressed.

Try using a different method to send it. Don't know which method you are referring to currently but in some cases it is usually dulled for data saving purposes.
