Question / Help Trying to understand the best settings for recording 1080p 60fps. Please.

[MDuck]

I have a i7 9700k, 2080 ti overclocked, 32gb ram. Currently i've been using VBR with bitrate at 40k and max at 100k these are things i saw were recommended here on the forums. My recording output is standard, going to mp4, encoded is NVIDIA NVENC H.264, keyframe interval is 2, present is max quality, profile is high, max b frames is 2. i rescale in video from 1440p to 1080p.

So can someone please explain to me why my videos will lag every now and then, my games are running 150-250 frames all the time even recording but once i look at the playback i see a lag every now and then usually under busy times in the game (shooting, driving, etc.). Please, any help would be great but no one ever replies here. I just need smooth, 1080p 60 fps.

Thank you.

You're overloading your encoder.

Simple output mode, indistinguishable quality, large file size (unless you need multitrack audio).

If you need to use advanced mode, use CQP rate control and a quality setting of 14.

 

[MDuck]

will a cqp of 14 still be good quality?

 

[Narcogen]

Yes, very.

 

[MDuck]

okay great ill send the latest log with this

 

[MDuck]

this is with the cqp at 14 in advance mode, even more drops

 

[MDuck]

This is with simple and indistinguishable quality, large file size. this was worse than cqp 14. any ideas that you can see from the log

 

[MDuck]

and heres my best result with VBR 40k bit and 60k max. so honestly i have no idea where to go from here

 

[Narcogen]

Increase the CQP rating then-- your machine can't record at the quality, resolution and framerate you've selected, so you'll have to compromise on one of them.

Try something as high as 23, see if the lag stops and see how the quality is, then decrease the number until you get a good balance of quality and performance.

I can’t record at 14 with an i7 9700k and 2080 ti overclocked. Then who can run a 14 or lower? And when I use vbr 40k and 60k it’s almost there.

do you have a ssd?
If yes record on it a few minutes and see if it works.
If yes your location to which you want normaly record is not fast enough to keep up with the video feed.
If not your settings are not good. I guess your webcam in the scene could be a problem.
I can record with just the game in the scene 2160p at 120 fps with a 1080ti and the nvenc on a 2080ti is better than on a 1080ti, so you should have no problem with just 1080p 60 fps.

exactly so i have no idea what could be the problem, let me try switching it to the ssd

 

[MDuck]

okay switching to the ssd for recording changed everything, now i can run any quality, CBR or VBR or CQP without any problems. how could that have been the case
