Example

This VB example opens an AVI file, doubles its frame rate and starts the playback.

fps=ActiveDcam1.GetVideoFPS * 2

ActiveDcam1.PlayVideo

Remarks

The actual frame rate during the playback of a video file may be lower than the set frame rate. This depends on the hard drive performance and the use of compression during the recording. If an AVI file is open with the sound option, the playback rate cannot be higher than 16 times of the recorded fps.
