Technical systems for video productions
Basically, the technology employed forms the foundation for further processing and use. The better the quality of the footage the less restrictions you have later.
The production of industry films contains different systems. In the past the best possible quality was the production on 70 mm film, which was used in High-End cinema productions, followed by 35 mm for normal cinema productions to 16 mm which were used for commercials or music videos. Nowadays all recording techniques are digital. Sony introduced a high definition TV (HD-TV) system on the market which allows high quality HD productions.
TV channels are realizing high quality features with a Digital Betacam or a XD-CAM. These professional systems are often used for the production of business-films as well.
In the field of professional HD-productions, digital single lens reflex (DSLR) cameras are regularly employed. With their big lenses it´s possible to create a high quality cinema look. However, their better creative options mean more expenses and require an experienced camera operator.
Today’s video cameras record in HD, but the opportunities to be creative are more restricted than with DSLR cameras. In return both costs and complexity are reduced. For lower costs and lower quality productions the footage of business-films is shot with digital systems DV-Cam or HDV by Sony or DVC-Pro by Panasonic. DV is a cheaper system from Sony and is developed mainly for amateurs. It´s used in TV productions for the creation of cheap content. The higher resolution alternative is HDV, which is more compressed than HD-TV and has a much lower quality.
The next levels are the video formats 2k, 4k and most recently 8k, which are used normally for cinema productions. The difference is the size of the frame.
–a video with a standard resolution has a width of 720 pixel
–a HD-Video has a width of 1280 or rather 1920 pixel (Full HD)
–2K has a width of 2048 pixel
–4k has a width of 4096 pixel. Due to its enormous data volume processing requires the fastest high-end work stations.
