Question / Help Two important questions for streaming / capturing in high quality

Hey guys. I really hope someone can help me here.

I'd like to capture gameplay for youtube and twitch. Both separately of course, I got two profiles. Can you guys tell me if I can record 1080p videos with 60fps? I tried it but it is somehow laggy.
My current rig:
NVidia Geforce GTX1080
32GB DDR4 RAM
CPU Intel XEON E5-1650v3 6x 3.50GHz So.2011-3 WOF
Download speed: 10-12mb
upload: around 10mb

Can someone tell me good quality options? As I said, I tried recording 1080p without downscaling and 60 fps but it lagged. :I
Also: My 720p60fps footage looks great but as soon as I upload it to youtube it doesn't like that nice anymore. I don't know why though, I didn't render it or change anything. Rendering always completely screws my quality, but I'll have to render my videos if I edit them. Don't know how to start there. But that's not important right now.
Here some screenshots of my current settings:

Recording:

Simple settings
Recording Quality Indistinguisable
Encoder x264 or NVENC
Format FLV.

Streaming

Video settings
canvas and output 1920x1080
30 FPS (twitch) 60 FPS (Youtube
filter bilinear (not used, really)


Output settings
CBR
3500 Kbps Twitch -30 FPS- 6000 Kbps Youtube - 60 FPS-
Encoding profile: faster or maybe fast for better quality (if no lag)

It somehow still doesn't look that great. :I
Small edit: I should also say that I'm almost only going to record Overwatch footage. xD

Hi,

Can you post a log from obs? how to do this is on the forum as a sticky.

To record use 1080p and Nvenc Encoder
to stream use 720p and x264 software encoder cpu preset veryfast

pick 30fps to start see how it is then move to 60 fps if you have the cpu headroom and bitrate to stream as you can't record and steam at different fps in obs.

This is my last logfile. :)

Thanks, the log doesn't show any session, can you run a stream and or recording with the issue and then post the log, each time you open OBS its creates a new log. The old ones are stored if you can recall the date / time.

Log doesn't contain the info, it should say ======= start recording ========= / ======= stop recording ==========

if you close obs after the record it and re open it creates another log, the other is located in the user / obs studio directory.

Yep thats the one, ok change the following settings as you are having this error

16:43:11.901: Output 'adv_file_output': Number of skipped frames due to encoding lag: 3471 (84.2%)

This is because the x264 encoder is cpu hungry so best kept only for streaming.

Starting settings as follows for recording

-Nvenc Encoder
-1080p
-60fps
-VBR (other options here can use CQP)
-40k Bitrate
-output .FLV or Mp4 recommended is .flv but it might require some rumuxing to import into an editor.
-audio from 44 to 48

If you want to steam later start with the following

-x264 software encoder
- CPU preset faster (you should be find on this but can lower or higher if you get lag or have some headroom)
-CBR
-720p
-if you want to run 60fps and you have the internet upload bitrate 3000
-if you want to run 30fps then 2000 bitrate (note recording will also drop to 30fps as obs can't do different fps for both)

test and any issues drop a new log, so to speak :-)

This is the new log file, I tried a little bit and the outcome, the MP4 file is AMAZING! But if I upload it to youtube ( without rendering it) it doesn't look the same. A little less amazing. Is this normal? :o

should I change stuff? everything worked out fine, no lags and so on.

https://youtu.be/ke1jWQcbNwc the rendered video. I'll have to render because I'll most likely always edit my videos. :I

Thanks again. You've already made my year. x3

Hi,

good news, Youtube will always downgrade the quality from the raw recording if your bitrate is higher than there recommended. If you have an editor you can play around with the export settings and this can improve it, but YT will always do some processing which compresses the bitrate to allow them to stream it back. The below is taken from YT recommended settings :-

Bitrate
The bitrates below are recommendations for uploads. Audio playback bitrate is not related to video resolution.

Recommended video bitrates for SDR uploads
Type Video Bitrate, Standard Frame Rate
(24, 25, 30) Video Bitrate, High Frame Rate
(48, 50, 60)

1440 p (2k) 16 Mbps 24 Mbps
1080 p 8 Mbps 12 Mbps
720 p 5 Mbps 7.5 Mbps
480 p 2.5 Mbps 4 Mbps
360 p 1 Mbps 1.5 Mbps

Recommended video bitrates for HDR uploads

So I should put my capture bitrate at 8k-12k instead of 40k? :o Or just leave it like it is because I cannot improve my quality. :3 thanks again buddy!
