In the 'Export As...' window I chose the export setting to be 'Send To QT Movie.'

I then chose options to go further in depth to the export settings. In the new window I changed the Width x Height to be 1920 x 1080, left the colour levels to be 601/709 and changed the Display Aspect Ratio to be 16:9 square pixel. 

In this window I also chose format options which took me to the Movie Settings window. 

Under video settings I changed the compression and resolution types as seen below. I also changed the Frame Rate to 25 fps. 

Finalised settings

After this I went back to the original 'Export As...' window and clicked save.
