unable to play video in photos

Hello.

Pls help me with below issue.

I made video by iphone. After finishing, I open the video but I see this message: "Unable to pay video. This video cannot be played because the file format is unsupported." The duration of video is 00:00. I tried to open video with Quicktime but can not.

A lot of videos can play without any problem. Only several videos are unabled to play. Pls help!
