You can use the `Time-lapse' feature, available in My Screen Recorder Pro, to record video such that it plays back at higher speed.
For example, to record a video at 5fps and play it back at 10fps, follow these steps:
1. On the Tools menu, click Settings
2. Select the AVI Video tab.
3. Under Frame options, select `Time-lapse'
4. Click `Time-lapse Setup'
5. Under `Record rate', specify 5 Frames per 1 second, which will make `My Screen Recorder Pro' capture 5 frames in one second (5fps)
6. In the `Playback rate' box, specify 10 frames/second
7. Click OK
Using these settings, you essentially playback a video file at twice its recorded frame rate, which doubles the videos playback speed. In other words, 10 frames are played back in 1 second instead of 5 frames.
If you expect your screen to refresh 2 times in one second, then set the `Record rate' at 2 Frames per 1 second. To playback this recorded video at, say, 2 times its actual speed, specify `Playback Rate' as 4 frames per second.
