Question / Help Downscale quality?
- Thread starter Haki
- Start date
x264 ( check : enforcing streaming service encoder settings )
Uncheck custom /
CPU usage : veryfast
profile: main
Tune (none) // You can try to use one.
Add this on x264 option ==> level=3.1 bframes=3 ref=1
On VIDEO : ( if you stream a console games) Set base resolution 1280x720
Scaled resolution 1280x720
Or if it's a pc game :
base resolution 1920x1080
Scaled resolution 1280x720
Downscale Filter :( depending your pc spec ) If you have a good pc set : Lanczos OR if not prefer set : Bilinear
FPS 30
Try this :)
Put your pc spec / a speedtest if it is Authorized

i see, you are on the ''simple'' version of obs my bad.
No
x264 ( check : enforcing streaming service encoder settings )
Tune (none) // You can try to use one.
On this version.
For : x264 option ==> level=3.1 bframes=3 ref=1
Go to : Settings => advanced And its : Custom x264 Encoder Settings ( check it ) and put :
level=3.1 bframes=3 ref=1
Your config/Connexion seems to be good

you are giving people bad advice and dont even know what kind of CPU they have. @Haki please dont use customer x264 settings and post your logfile. you can upload a logfile from the help menu
you know what is this custom x264 ? ... Search on google if you want, see on the x264 wiki page. or just go on twitter and ask to @Aika_64
Don't say i give bad advice if you don't know...

is there other version of OBS? Not to use x264? Should i use nvida nvenc?

There is OBS MP(aka studio) but it is in beta for now, a few features still missing so I wouldn't recommend you use it for your primary streaming software.
you should be able to use x264 just fine, but NVENC and quicksync are both options, but bit per bit, they have less quality for the same bitrate.
downscale using Lanczos is the sharpest downscale method. you can play in 1080 and stream in 720 which is fine, the best bitrate for 720@30 is 2500 bitrate and buffer. you could raise your bitrate/buffer up to 3000 but 2500 should be find for 30fps.
I set 2500-2500
x264
cbr
cbr padding
set base to 1920x1080 and downscale 1280x720 and set Lanczos. As you can see here i will stream 5-10 min im not happy with quality. http://www.twitch.tv/mmohaki

set CPU preset to fast. you have the room on your CPU for that at 30fps. set bitrate and buffer to 3000 as well
This is bad advice, these settings are not needed for Twitch. Custom x264 encoder settings need to be empty.
can you post another link to your twitch past broadcast with the new settings and another logfile? your thoughts of what an excellent stream should look like might be to high. the bitrate and preset you are using should actually be one of the best quality around.
Im streaming now with these settings

I dont know how to set past broadcast. Perfect would be if i stream 1080p becauce with that its very good quality. But i want to stream 720p which wouldnt need much bitrate, i really dont know how i cant play 1920x1080 and stream 1024x720 with good quality.

@Haki, do you need low latency mode (low network impact?) if not, disable it.
Code:
21:45:06: preset: veryfast
21:45:06: max bitrate: 2500
21:45:06: buffer size: 2500try setting preset to faster and bitrate/buffer to 3000. quality should be
I think your expectations of stream quality are way to high.
yes, 720 will have less quality but good enough for streamers to watch you. 1080 will have much more quality but needs 3500 bitrate to look decent when movement is happening. I would not use faster preset with 1080@30. use veryfast with 1080@30.
I was checking for another 2 hours whats going wrong.
downscale to 720p and i run some analyze:

Can someone tell me why i see in both reports EU quality low and connected with french server when i set Frankfurt where i have average ping 45 and jitter sometimes 0, sometimes 5.
VBR in use
Consider enabling CBR for improved stream quality. CBR will use a fixed bitrate which allows a smoother network stream, reducing the chances of frame drops for both you and your viewers.
I cant find VBR option and CBR option is already enabled so why is it telling me to enable CBR when its already enabled?
Slower preset in use
You have changed the default preset to faster. Using slower presets can result in late frames and high CPU usage / low FPS. You should only change the preset if you are sure you have the CPU power to spare.
Again, this is not true. I was using very fast and after that faster option. So i should leave faster?
Bad resolution / FPS / bitrate combination
The combination of settings you are using will likely lead to a low quality stream with artifacting and other problems. Consider either raising your bitrate or lowering your resolution / FPS (qval: 0.027)
This is funny part, i set 1800 - 1800 and i saw this, then i set 3500 - 3500 and i saw this msg again.
Its downscaled to 720p, i can do whatever i want but quality is same.
