The use of HD in Film and Web

HD wedding vintage | Wedding Video SolutionsFollowing on from last week’s article on the history of HD video here we explore the use of HD in film and on the web.

There are some intrinsic limitations that are associated with film as a medium. One of such limitations is the complexity of viewing the footage during the recording activities. Secondly, there is also the problem caused by poor development and processing of films, or very poor monitoring systems. Based on this and the fact that there is an upsurge in the usage of computer altered or computer generated imagery in movies (and that the process of editing picture sequences is usually carried out digitally), some film directors have shot movies with the use of HD format through high end digital video cameras.

Although, the value of HD video is extremely high when compared to the SD video, and provides enhanced noise/signal ratios alongside comparable film sensitivity, films still remains adequate to resolve more details of images when compared to the current HD video format. Also, many films have a huge vibrant range (that is, the ability to resolve excessive light and dark areas in scenes) in comparison to the best HD cameras.

As a result, the most convincing arguments for using HD video format is the cost effectiveness on the stock of film and the simplicity of transferring to the editing systems for unique effects. The image exposed varies in size depending on the particular format and the year that the movie was filmed. The sizes vary from about 24 mm x 36 mm for the Technirama/ Vista Vision eight perforation cameras and 18mm x 24 mm for the Full Frame or Silent Films four perforations cameras. It also gets as small about 9mm x 21 mm in the Academy Sound Aperture modified cameras for Techni- scope two perforations format.

Other film gauges are also used in producing movies, inclusive of 70 mm films. There are four major formats used for films. These are Current Anamorphic Panavision, Academic Sound, Academy camera Widescreen (US) and Super 35 for Anamorphic Panavision. They all have their calculated pixels done per mm. there are a great number of online video on demand/streaming and various digital download services offering HD video today. Some of them include Hulu, Netflix Watch Instantly, Youtube, Amazon Video on Demand, and Vimeo among others. As a result of the high compression, the detailed image that is created by these formats is very low when compared to the broadcast HD. They are also substandard to DVD Video.

Needless to say, Wedding Video Solutions shoot only using the very latest in broadcast specification HD video equipment so you will only find the absolute best quality and detail in your wedding video.
