Question / Help Having trouble recording 720P + is my PC too weak?

Hi,

So iv'e been using OBS for quit a while now for local recordings.
It works great, but i had experienced some FPS drops when i recorded "heavier" games.
I always recorded them on 1080P 60FPS, so i decided i should lower my resolution to 720P and stick with the 60FPS, and that way my computer should be able to handle the recording.

So i downscaled the resolution from 1920X1080 to 1280X720 and it seemed to work just fine as i had no frame drops, but then when i watched the recorded footage i noticed the quality was horrific, it was pixely and blued.

The weird part is that when i looked at OBS during the recording the footage
looked great.

So what can i do to record on 720P 60FPS instead of downscaling the resolution? because it seems that's no good.


*BTW, it's kinda weird, but i even have trouble recording games such as Minecraft without frame drops, is my PC really too weak for recording anything?

My PC Specs:

8GB RAM
Intel Core i5-4570 3.2GHZ CPU
Nvidia GTX770 2GB Graphics Card


Thanks to anyone who can help :)

for 720@60 local recording, you should be fine.

Set buffer to 0, bitrate doesn't matter, uncheck CBR set Quality Balance to 7 and your x264 preset to superfast.

I uploaded test a footage using your advice, still seems a bit low quality to me.
Also, i'm still getting major frame drops when recording certain games, even with these settings.
I tried to record some Cities Skylines footage, but there were consent frame drops, even to a point of 13FPS, it's unbearable.

What else can i do to record 720P 60FPS footage?
It's driving me mad seeing people with worse PC's recording normally 'heavy' games while i'm struggling with pretty much everything.

change quality ballance to 9 see if that makes a difference, and please include the log from that session once you are done.

Well i just tried to record some footage, i had no frame drops (in-game or recording) but quality still seems to be pretty bad.
I'm pretty sure it's a problem with OBS, because when i recorded 720P with Shadowplay it seemed to work just fine.
And when i used Frpas back in the day i could record pretty much every video-game on 1080P and 60FPS, only reason i stopped using Fraps is because the file size was ridiculous in comparison with OBS.

Here's the log file of my last recording:

Such is the problem with Fraps, there is no encoding done then. so you want tip-top quality?
https://obsproject.com/forum/resources/how-to-make-high-quality-local-recordings.16/

I would recommend you step it down slowly with CRF (not CFR) start at 15 (which should be enough) and move it down slowly until you find the peak quality.

Also notice which filter you are using for downscaling. Lanzcos is not the sharpest, but is the smoothest. Bilinear is thee sharpest but i'll leave that up to your judgement.

Hey dude, thanks a lot for the help!
I managed to get a good quality 720P 60FPS local recording using your tips :)

I switched the filter to Bilinear with a CRF of 17 and it work's fantastic, i do have 1 or 2 frame drops when things get wacky in the game, but after fiddling around with the settings i managed to get it working perfectly.

Thanks bro!

you can always change your preset to superfast (not ultrafast) without loosing quality. It will just make the files a little bigger, but still not as big as a Fraps video
