High-speed videography
It is used for recording and vizualization of fast-moving processes that cannot be seen with the naked eye. High-speed video cameras are widely used for:
- Scientific-research programs: registration and video record of fast-moving processes, e.g., hydrodynamics tests.
- Arms industry and firing grounds: test weapons and protection, ballistics, blast slow motion picturing. Related videos of bullet impacting metal objects can be found here.
- Aviation and space: high-speed filming of gas turbine engines, missile's launches, aerodynamics, testing aircraft seats.
- Setup and diagnostics of high-speed production lines, troubleshooting: packaging, cigarette manufacturing, plastic bottles, etc.
- Automobile industry: car crash and airbags tests.
- Sports and Medicine: biomechanics, athlete's movement analysis.
- TV and movie industry: special effects, advertising, sports competitions.
Russian High speed camcorders
Camera Fastec HiSpec 1
To promote the activity of SPBPU as national research university high speed camera Fastec HiSpec 1 was bought in 2010 by Department of Theoretical and Applied Mechanics. It allows to obtain an image at up to 506 frames per second at a resolution of 1280 x 1024. This camcorder has a high sensitivity (color photography to ISO 1600).
Examples of shooting modes:

- 1008 f/s — 1280 х 512
- 2312 f/s — 480 х 480
- 112183 f/s — 144 х 2
