High-speed film cameras can be used to capture the moment of action and record it for analysis.
Researchers can then study the processed films in slow motion or even frame by frame.
Film cameras are large and heavy, the film is expensive and time must be allowed for developing. Video enables the user to feed digital images directly into a computer, producing the required information for accurate analysis in just a few seconds. However, video cameras are normally unsuitable to capture high-speed events because they are unable to film fast enough or in sharp enough detail. They are normally spin-offs from research conducted by the European Commission's own Joint Research Centre. A new technology had been developed during advanced optics research conducted for the Commission.
