How does screen-recording software work?

[AstroBenny]

If my fps in game is about 250fps, how when I record at 60fps does the screen recorder know which frames to take in every second. In an ideal world you would have your game running at 60fps and the software capturing at 60fps so how does the capture software manage what is recorded??

It works by time? 1 second 60 frames. Game is 1 second 250 frames, whichever ones of those 250 fall into place for those 60 are picked. Same way monitor displays 300 fps when refresh rate is 60.

But if the capture software takes the first 60, what about the other 190? Surely there would be huge amounts of stuttering?

I said it works by time... It doesn't take the first 60 it takes one at the time it needs one...

I always thought of it as pressing your screenshot key so unbelievably fast that it made up a video when looped up and shown one after the other - you know, "moving pictures"?

No not really. I know this is a bad example but look at MineCraft. Most YT people I know don't cap FPS at 60 when they record but there is no stuttering. YouTube displays videos at 30 FPS and anything over doesn't matter, it is still fluid. When it is under 30 FPS you can see stuttering. Or 60 FPS sometimes if it is rendered and uploaded like that.

So what happens if you have lower fps in game than your screen recording fps. Does that result in stuttering?

It takes 60 frames per second, so 1 frame every 0.0166 seconds.

Doesn't matter if you have 10 fps, or 300 fps, it just takes a frame every 0.0166 seconds which results in 60 frames per second

It just takes the same frame twice. It will stutter as much as it stutters to you.

Yes, it still stutters.

Well yeah...you are recording at a higher rate then your game so it won't look good at all.

That usually means that your hardware isn't good enough for recording. Recording drops some frames because all resources it need. So example from my BF3 recording days. Normal fps of 75 was dropped by 10-15 while recording at 30 fps. Game was still fluid enough to play and recorded stuff was also smooth.
