Question / Help Drop quality during stream ....

[Jenosu_]

Hello,
I've actually a good connexion for stream :

And i would like stream, but sadly, i dont understand why, when i try to stream in 720p 60fps with OBS the quality is like 480p or 360p at some moment ... However, when i look other stream, some youtubers can have a very good quality without drop of quality like me.

My OBS settings :

Ohter important information :
My configuration is quite good : 960+i5+8go ram
All of my settings was chose by looking tutorial on youtube
I looked for a lot of answer in different forum but no one have the solution of my issue
I pulled my bitrate of Twitch Inspector whos told me i can have 5300
Sorry for my bad english i'm french :x


Thanks to everybody whos will reply ! I am really desesperate because basicly with 5000 bitrates its largely enought for stream in 720p 60fps . I hope find someone whos know the solution of my issue ...

For the Advanced Settings, keep Color Format to NV12, Color Range to Partial and Color Space to 601. Chrome, Firefox and very likely most other browsers do not support anything else and will assume NV12 601 Partial.

Next for encoding, set Profile to high and Preset to High Quality. That should improve quality a bit. If you have a really good CPU (doesn't look like it) you can also switch over to x264 veryfast and get a bunch more quality out of it.

Hi man ! Thanks you a lot for you answer but your advices look doesnt work :/
You can watch a upload of a live test here : https://www.youtube.com/watch?v=YoY_9c8pTXc or a screenshot of the live quality : https://gyazo.com/aecd73922cd1bec02083137d41c3bdc4
In game the quality is like very very nice ! But in this live I tryed the x264 veryfast and I dont have FPS probleme but same quality issue and i tryed with NVENC H.264 and I have the same issue ....
Thank you i hope you will find a solution :)

YouTube footage is not an accurate representation of the encoder output as YouTube transcodes on their end. Take a look at an actual recording instead of a YouTube stream/upload to see what it really is like.

Also if you are streaming to YouTube only, your 17.73mbit should allow for a 1080p60 at 12mbit stream which gives more quality.

Hi man ! Thanks a lot for your answer again.
Indeed, on twitch its look a lot better, but its still a little bit pixelated and now i have FPS problem ... On my screen its nice no one fps problem, but in stream its look like I have some freez and the quality can down to 480p like before but much less serious !
Thank you for all of the time you spent to me, if you dont have the solution no problem :)
