We always film in High Definition (unless this is discussed beforehand) but you can choose whether to receive the final wedding video as DVD or on Blu Ray (BD). To get HD onto DVD it is downconverted to Standard Definition. There is always a slight degradation in quality in this process, though the quality is still excellent. A High Definition BD will give you a much sharper image. The 2 images below were taken as screenshots from a wedding video and show the difference.
A BD can hold more data, so if you choose for us to stay longer to film your wedding we can fit more on 1 BD disc rather than splitting it onto 2 DVDS.
A BD can have nice Pop Up Menus so that you can access the Chapter Menu whilst watching without having to go back to the home page and find the chapter.
