Question / Help Upload speed acting up

Something is wrong with my twitch upload speed, i keep getting a lot of dropped frames. I have been streaming for a good 3 weeks now, and up untill now i have had no major issues with streaming, i have been using 10 quality and 1600 max bitrate in settings and it has all been fine with 0-3% dropped frames on average. Today i have been facing major problems with streaming though, at one point the frame rates became horrible, going up to 76% lost frames. When i looked at the OBS window, i saw the color next to the upload rate was constantly red at one time and it kept switching between 0 kb/s and 515-525 kb/s upload speed. Like there were small periods it was streaming relatively fine, and then it dropped to that cycle of 0 and 525 kb/s again

Havent changed anything, my rig is the same and my connection is the same, i have no idea what could be the problem, uploaded a log aswell

any ideas?

CBR is required for Twitch, according to their ingest specification requirements. Turn it on.
Also, 1400kbps is nowhere close to enough for 1080p@30fps video; it's even below the generally accepted minimum for even poor-quality 720p@30 video (1500kbps). You'll want to downscale; as-is it'll look terrible for anything higher motion than Hearthstone, and even that will be debatable.

Yep, according to that log, your connection to Twitch just went to crap.
Network fluctuation happens, and routing can change without you altering anything on your end. You can end up just stuck with a bad roll of the dice some days. Download the Twitch Bandwidth Tester, and run it as Admin to check which servers you have the strongest connection to:

This can vary day to day, and even beyond that there can be ingest issues as well.

your biggest issues is you are not using twitch recommended settings. you need CBR and padding as well as it would be best to downscale your video to 720p. bitrate is very low even for 720p but that is just a starting point.

Thanks for the replies, i will try these tips tomorrow, could you guys be bothered with giving me the optimal settings for OBS? The quality of the stream was not that horrible even with the settings i had... speedtest gave me 5 mb/s upload speed, which probably isnt that great, so i guess i will need to find some good balance between quality and performance?

If there were optimal settings for everyone, they would be posted by twitch which they are. the remainer of the settings are optimized by streaming for 5 minutes with twitch settings in a live game then posting your log back here.

So i tried tweaking some settings, on my second attempt with 1600 bitrate and 720p downscaling it ran very smoothly for a couple of minutes at the beginning, but then the colour went red again and i began losing a lot of frames

Heres the log

Do you guys reckon its still my connections problem? speedtest always shows around 5 mb/s upload speed, and as i said, i was able to stream fine before. Although this doesnt make much sense, the only variable was that another streamer i know made a multitwitch right before my problems started. I guess it cant be the problem, but what is the problem then? :(

I even lowered it to 1800 and downscaled video to 720 on the second attempt in that log

you only have 1Mbps upload from your ISP. that is 1000 bitrate which doesn't include the audio bitrate.

lower your audio bitrate to 96kbps set normal bitrate to 700 and downscale to 360p. from there stream for 5 minutes then post your log and I'll take a look at the results.

Also notice the quality column on the right. that number needs to be 70% or above. your quality is 0.

Man bitrate or anything doesnt seem to be the problem if i get 0 kb/s from time to time, it even disconnects and says reconnecting...

i tried with the settings you suggested, it still has 75% lost frames, none of this makes any sense :(

the reason unchecking vbr worked for you before is because when there is no movement it doesn't send out changes. CBR with padding does though, but is needed to shape traffic to your ISP. In this case your upload is really bad and you cannot sustain even 796 bitrate. recommended at least 2 or 4 Mbps upload speed to get what you need. you want to have above otherwise your internet traffic will be strangled by the stream.

at that, you should probably uninstall raptr (gaming evolved) since it comes with AMD drivers. it will interrupt with OBS especially if you are broadcasting with that as well.

Alright, so i uninstalled Raptr, after that it seems that the main problem where i sometimes had 0 kb/s upload speed has disappeared. I live in a dorm and the dorm is caneclling a contract with the previous internet provider, so maybe thats the reason the upload speed is being sketchy, it should be okay once they put in the new internet, which shows 80 mb/s upload on speedtest, that should be more than fine for streaming i guess?

Anyway, i tweaked some settings for now, and it seems with a lower resolution and a bitrate of about 1000 it streams relatively fine with 5 - 8% lost frames

posting the log here

Sacrificing more quality would probably result in a unwatchable stream as the quality is too shite :P

80Mbps shared could be horrible or it could be great. It really depends on who else uses upload speed.

When you get your new ISP in, I would do 1500-2000 bitrate (1.5-2Mbps) and increase your downscale to 1.5 1280x720
