upload speed for streaming?

[iLostMyXbox21]

so i hear 3mbps upload should be enough, but is it different for ps4? also, do i need more snice i wanna stream an online game? 

 

i wanna live stream R6s to yt or twitch

 

another question to avoid 2 different posts:

 

how do i know the actual speeds im getting on my ps4? like the build in test says i get 40mbps download but everyone (including the person who hooked up our internet) says it is not accurate..

Just hook yourself up to Ethernet and if you pay for good internet speeds then it's nothing to worry about.

3MB up is usually recommended for HD(720p) streams.

we pay for 100mbps download, but idk about upload

what about for 1080p?

Run a speedtest and find out what your upload is.

1080p is around 6MB up if I recall correctly. Also keep in mind that encoding a 1080p stream takes a fair bit more power than 720p.

It is?

 

6Mbps should be fine for 720p but 1080p would be bandwidth starved.

 

10Mbps should be fine for 1080p.

idk about encoding because i use ps4 for streaming, so i can only change the quality and a few other things, but not bitrate or encoding

and how do i know the true amount i get on ps4?

There's megabits  (mbps) and megabytes (MB)  .... there's 8 megabits in 1 MB

 

Your internet plan and your internet speeds are in megabits ... you get  100 mbps download (that's around 12.5 MB/s) 

 

The maximum streaming speed will be your upload speed, minus around 0.5 - 1 mbps. If your ISP limits your upload speed to 3 mbps, you CAN NOT configure your broadcast software to stream at 3 mbps, because the video stream is not the only thing using the internet at that time, so some "room" must be left for other things.

At best, you'd probably be able to go with 2.7 mbps  ... 0.3 mbps must be left as reserve, for other things.

 

There's no  set bitrate value for a certain resolution, it really depends on the quality you want to achieve with your stream and the type of game you're streaming.

In general, it is said that 3 mbps is enough for 720p, in the sense that you get a reasonable amount of quality in that amount of data. 

For 1080p, most people say 6 mbps because that's the maximum value Twitch allows "regular" people to upload at, while Youtube allows even 10mbps or more. For a majority of games, 6 mbps can be enough for 1080p, but for others it can be too little.

 

You  can use hardware encoding to stream a game, or you can use your processor (software encoding) to encode the video and upload it.

PS4 will use hardware encoding, it uses a tiny dedicated portion of the video card to compress the video. The same can be done with PCs, using nvEnc or AMF to use the video ard to compress video. 

These hardware encoding options can compress video fast and with minimal processor usage, but because they're fixed in hardware they have minimal configuration options and in general the quality is a bit worse compared to software encoding.  For example, at a fixed bitrate like 3 mbps, you could say the image quality of hardware encoding could be only 90% of the image quality of software encoding.

 

If you have a powerful processor, you can use software encoding to compress the video and then you have a lot of options... you can trade image quality to compress faster and with less processor usage, or you can increase the processing power in order to squeeze more image quality in an amount of data.

So for example, you could get the same image quality if you use 2.5 mbps and 50% of your processor power  OR 3 mbps and only 35% of your processor power ... same broadcast quality but you're trading more upload data for less processor used.

 

Your PS4 will have some options in some menus somewhere, where you can configure how much bandwidth to use (that mbps value)

 

If it doesn't let you, then experiment ... stream to twitch  at various quality levels and watch your own stream using a PC , click on the GEAR icon in the corner, select the (source) at video quality and then from Advanced, enable "video stats"  and you'll get something like this:

 

 

ninja is big deal streamer on twitch so he's allowed to use more than 6 mbps .. so you can see he streams 1080p 60fps at 7.5 mbps  (~ 7530 kbps when I took the picture)

im not sure of my upload speed, it changes every time i check it.. sometimes i get 3 sometimes i get 10.. i think the most common ground is 5 or 6 but the best i got (idk what was happening) was almost 400 upload (it was around 370 or so) which only lasted for a few minutes but it went back down to the normal... but the ps4 test is actually not accurate. it will say i get 30-40 download but when g in my computer (or the service provider tests it with their tablet) it is about 70-100 which is what we pay for.. they way they talk about it is “megabyte” and not megabit, i do not know if they just make the same mistake everytime we talk to them.. but that is what they say. all i know is i always have my ping within 1-30 when gaming and i stream offline at 1080p with no lag, but that is not hardlined.. i have not tried streaming an online game while hardlined but i tried when not.. and i had a bit of lag. however that was solved when i switched games (i was playing paladins but switched to r6s)

Ninja also pays for fiber internet

[mynameisjuan]

OP if you are getting 100 down you most likely are getting 10/15 up. 10megs is plenty for 1080p. 

 

Just run a speed test.

I have cable internet and my internet plan is 500 mbps down / 25 mbps up and I get these speeds 24/7.  Competition offers more, but I don't need more and i prefer reliability. 

Point is quality internet connections can be done on cable or even other means, you don't need fiber to do < 10 mbps as Ninja does. You just need a decent ISP.

 

Anyway back to topic...

 

When you're doing speed tests, of course speeds will vary because the test will be done against a random server (computer) located in a random part of the country. The site with the speed test will try to assign you a server that's close to you but it's not guaranteed. So for example, if you're in US, at one moment you may test your speed with a server in Seattle, and a half hour later you may test with a server in Texas... 

The longer the distance between you and a remote computer, the higher the chances the speed will be a bit slower.

Use http://www.speedtest.net/ and after you do the initial test, go through the interface and pick various locations around your town (click on settings and then click on Change server)

If you're in US, Twitch has servers in several datacenters, pick some of the bigger places that have huge datacenters, like Dallas, Chicago, Washington .. these are places where  Twitch most likely has servers.... actually you can see here the locations: https://stream.twitch.tv/ingests/

So you can check your upload speed to locations where Twitch has servers, find the closest geographically to you and test.

Run a speed test on your PC or phone to get an estimate of upload. We can tell you how much you need all day.

Whos your ISP? That could be a good indication on what you got.

Id say maybe 5-10 Mbps. That what most cable cos give. Unless your WOW and you give 50 Mbps. But most cable co's have shit upload speeds. 

[AbsoluteFool]

1080p 60fps will be beautiful with 4.5Mbps to 6Mpbs, anything more is foolish and idiotic. 

Read the information available at Twitch. https://stream.twitch.tv/encoding/ they also applies for other streaming platforms.
