Thanks for your reply. I have attached the .webm format file. Not the mp4 file format. I think you changed the file format (webm to mp4) Please check the file once agian. File name - (chrome-design-issue-windows-Windows 8.1 Pro 64-bit.webm).Just drag and drop file to the chrome browser. That's all its working. No need to other video format. 

No need to change other video format
