Some manufacturers of consumer cameras now offer a slow motion filming capability in their products. However to achieve the speeds required for high speed image capture a lot of critical functionality and capability are sacrificed.
The most common features that are lost are :
- Image quality, where the image resolution is extremely limited and the image is often heavily compressed.
- Limited recording time - due to the design of the camera, typically on a very limited number of high speed frames can be captured;
- Generally these cameras do not have any shutter speed control - a major problem when capturing high speed events as most high speed filming is shot between 250 to 1000 frames per second (fps) but with a shutter factor many times faster than the frame rate to eliminate blurring, a major problem with high speed filming. Without fast shutter speeds useful analysis of the result is worthless, also image compression also degrades the analysis quality of high speed filming.
- Inaccurate timing and inability to trigger the camera from an external source, limiting the usefulness of the camera.
