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?

OBS is what I use to record my screen. It is mainly for streaming to websites like twitch but they put a functionality of recording the stream as its going that records in lossless. Also you don't need to be streaming to record. Better than any program I have ever used, it's free, and you can change the frame rate! Picture I found on google of the frame rate highlighted

Note: look up on YouTube how to setup your desktop for capture

  • Can you select just a portion of the screen to capture, or does it have to be the whole screen? – IDontWorkAtNASA Mar 5 '15 at 18:08
  • @IDontWorkAtNASA It can record whatever part of the screen you want – Colton C. Mar 5 '15 at 18:55

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).

Fraps also allows you to record at any frame rate you want. Though the free version has watermarks in its recordings.
