Question / Help When recording video/stream lagging

Hello. I want to start stream to twitch.tv, but my CPU is 50% when i using OBS and video is lagging.

I'm moving your thread to the proper Mac forum.

also, you have a really old dualcore CPU so downscaling to the lowest will be a necessity.

Internet speed. I think it is good

What i need to downscale for example?

the lowest downscale in the list. and internet speeds dont mean much when your CPU is weak.

ZauY · Aug 11, 2015

i dont realy geti g what i need lower in my settings is there some help or video for it?

And if i am recording with other app (screenflow) it isnt lagging.

you are lowering it because your CPU usage is to high for you and the video is lagging.

OBS just doesn't capture raw video and send it to twitch, that would be huge, it captured, then translates it to a readable form (NV12) then downscales then encodes, not in this particular order.

Anyway, CoredDuos are not strong CPUs so if you want to encode without lag, I suggest you buy a better PC for encoding or buy a GPU with hardware encoder (h264) or upgrade your motherboard and CPU

OR

downscale further like I suggested.

This is a duplicate of another thread you already made. I'm deleting the other one. Don't post duplicate threads.

That log is incomplete. Can you please post a log where you do a short recording, then restart OBS and then upload your "Last" log file?

ZauY · Aug 12, 2015

Here you go

part of your problem is that medium preset. change to veryfast which is a perfectly fine, default preset. dont be fooled by the name

ZauY · Aug 12, 2015

And it is all what i need to change?

try it and see. unfortunately the logfiles from OBS MP dont tell me how your Pc is handling it and you didn't really record long enough to do anything but post a logfile. best to record for at least 5 minutes then post a log. but that wouldn't tell me much more anyway.

ZauY · Aug 12, 2015

Here go 3 mins i think

Looks fine to me but how does the video look? you had one dropped frame (which occasionally happens).
set CBR off and buffer to 0 for better quality recordings.

ZauY · Aug 12, 2015

ok i will do it, but tomorow because it is late in my country already :D

ZauY · Aug 15, 2015

My log an how look my video

ZauY · Aug 15, 2015

dont know which is real there was 2 more

you keep changing things and which is why I cannot help you fine tune this. which again your CPU is weak.

Code:

16:27:08.678: [x264 encoder: 'recording_h264'] preset: placebo
16:27:08.678: [x264 encoder: 'recording_h264'] tune: film

Quit touching things that you dont know what they do! dont use tune film and set the preset to veryfast and dont touch it again.

my ONLY advice for you to livestream is to get a GPU with hardware encoding to take the load off your CPU and it will also help you in games. nvidia uses NVENC and AMD uses VCE, to which even the more modern low end GPUs will have this feature,
Nvidia: 7XX or 9XX series GPUs i believe
AMD: most 7XXX, some R5 200, most R7 200, and all R9 200/300 gpus

but you will also have to switch back to the old OBS that will support this.
