Can the playback speed of recorded files be increased, for example, by two or three times the recorded speed?

I want to record an eight hour period of time.
My intent is to be able to playback an entire 8 hours of recorded realtime Futures or stock market charts in half the time or less ...I envision the playback to be closer to a speeded up "Snapshot Slide Show" where the individual slides/snapshots were recorded 1 second apart.

The application that produces these charts refreshes my screens 2 times per second. There would be very little additional activity on the desktop during the 8 hour record period that would need to be captured during the recording of the chart "snapshots".

I assume my recorded file settings would have to be set to record a very small file size -
Frame Rate: 1 frame/second (?)
Key Frame Rate: 60 frames/second (to match my Monitor's Hz setting?)
Or could I go lower than the above settings?

Is the above idea feasable with My Screen Recorder?
