What software is available for recording in 1/60 FPS? I am recording my computer screen which updates once a minute. I want to record for around 8-12 hours uninterrupted, and I would prefer not to compress the video because the details are very fine and any grainy pixelation would potentially make the video unreadable. 

Is there any (preferably free) software I can use which records at 1/60fps and can output a lossless (or very close to that) format?
AutoScreenRecorder (currently version 3.1) appears to allow you to record as low as 1 frame per minute in the Pro version only (the free version does not allow altering the framerate).
