Capturing smooth screen recordings

[techmot]

Hi, does anyone know if it's possible to get a good screen recording capture from using OBS?. I am trying to capture a video with OBS not a game, but no matter what framerate I use I still get a jerky/stuttery capture. I have tried capturing at 30fps and 60fps, they do seem a bit more smoother than using 25fps but not much. I know I am going to be told that using a screen recording isn't great but there is no other way I can capture the video. Does this all depend on the processor or is it just the down to the capture program?.

It is possible, thousands of people use it. It's a realtime operation, so any bottlenecks in the processing will be exposed.
Run as lean a system as possible (consider a clean boot ). Close all other programs, make sure you have plenty of disk space.
If you're capturing using AVC/H.264 video, use a fast preset.

What is the source? Video like VHS is interlaced and should be captured accordingly. I have not yet seen a rasonable capture of interlaced footage using OBS screen capture. Maybe somone can prove me wrong. But anyway, in addition to what has been recommended - and assuming the deinterlacer is acceptable - one may want to set the monitor refresh rate equal to the capture rate or a multiple thereof to possibly reduce glitches and judder.

Thanks. How do you mean by clean boot?. What about framerate in OBS, should it be set to 25, 30 or 60?. The screen recordings I have been capturing to test are sometimes at 25, 30 and 60. I find that 60fps seems to be smooth out the juddering on the captured file (playing the file whilst capturing there is no juddering at all). I have sometimes captured at 25fps and then encoded the file in Premiere Pro and set the framerate to 60, and it does seem to improve things.

In OBS the encoder preset is set to "Slower (better quality)". Setting it to fast, faster or fastest would give less quality, but is that the best option to reduce the stuttering?. Video encoder is set to NVENC h.264. Recording quality: High quality, medium file size.

What I am trying to do is to capture video from a website. And no this isn't from a pay site. And I've looked at the video streaming section on here but things like coding and command line is way beyond my understanding, and programs like StreamFab don't seem to work on the videos I'm trying to download.
