I Have a Good Pc but Bad Upload Speed for Streaming
At that place are many components that determine the quality of online video streams. One of these components is net speed. Different streaming setups require the back up of dissimilar internet connections. Some broadcasts require faster internet than others due to several variables.
In this post, we're going to discuss everything broadcasters need to know near cyberspace speed for live streaming. Nosotros will cover the basics of internet speed for live streaming before we become into how to decide the best internet speed for your stream.
From there, we will discuss ideal cyberspace speeds for many different use cases. To wrap things up, we will hash out the importance of viewers' internet speed.

The Basics of Internet Speed for Live Streaming
A lot goes on behind the scenes to make online streaming possible. Different types of engineering science, including streaming protocols, piece of work backside the scenes to carry chunks of data throughout the live streaming setup to user-facing video players. Online video streaming requires an net connection that is steady and secure.
There are two measures of internet speed: download speed and upload speed. As a broadcaster, you demand to pay attending to the 2d part of your internet connection speed: upload. In general, our recommendation for live streaming is that your upload speed should be at least double the total bandwidth yous'll use.
The best blazon of internet connexion for alive streaming is Ethernet. This sort of connectedness is both stable and reliable. If Ethernet is non an option, WiFi is a close 2nd. A wireless connectedness can go the job done, but information technology is less reliable.
If neither Ethernet nor WiFi is bachelor, cellular information is the last resort option. If cellular data is your online selection, nosotros recommend checking out our guide to remote streaming .
What is a Good Net Upload Speed for Live Streaming?
Many broadcasters are left wondering what the all-time internet speed for live streaming is. However, that depends on several factors. Your cyberspace speed should exist at least double the bandwidth that your stream volition utilise.
Unlike streaming scenarios accept different technical requirements.
In general, an upload speed from 672 kbps to 61.5 Mbps volition get the chore washed.
Clearly, this is a very wide range, and then it is important to evaluate your unique streaming needs to get a more accurate answer.
In order to requite you a ameliorate understanding of how this works on a technical level, let'southward quickly break down bandwidth and 2 related streaming metrics.
Video Bandwidth
Video bandwidth is the amount of data transferred during a stream. Bandwidth is important in broadcasting for a few reasons. Showtime, it affects what sort of cyberspace speed yous need. How much bandwidth you lot employ too affects your alive streaming costs .
Your bandwidth usage is determined by several factors, but the main 2 are video bitrate and video resolution. That's why higher-traffic, higher-quality streams crave more bandwidth.
Video Bitrate
Video bitrate is the corporeality of information that is transferred over a specific period of fourth dimension. It is oftentimes measured in bits per second or bps. Smaller files employ kilobits per second or kbps.
Bitrate can be manipulated at the encoder level . This manipulation is used to change the video resolution.
Video Resolution
Video resolution is the number of pixels forming the video frame, creating the video'southward epitome on the screen. In well-nigh scenarios, the more pixels a video contains, the higher the quality of the video. More pixels can yield a clearer image.
Resolution measures a video's width by summit in pixels. For example, online content with a 1920 × 1080 video attribute ratio would measure out 1920 pixels forth the bottom and 1080 pixels in height.
Higher-resolution streams consume more bandwidth, therefore higher resolution videos require faster cyberspace. If you try to stream a high-resolution video with a tedious internet connection, your stream may lag or get inclement.
Download Speeds for Viewing Live Streams
Streaming quality seems to accept increased over the years, with video start failures downwards 33% twelvemonth-over-year, buffering downward 41%, and picture quality up 25%. One of the reasons for this is the gradually increasing speed of internet connections. Both mobile networks and habitation internet services are increasing in speed.
Remember how we discussed that at that place are 2 aspects of internet speed? Every bit we mentioned, upload speed is important for broadcasting content, merely download speed is important when it comes to watching streaming video.
Today, the boilerplate download speed in the United States is around 99.iii Mbps.
Here are some general guidelines for internet speed and streaming video:
- 25 Mbps: sufficient for streaming 1080p HD video
- ten Mbps: sufficient for 720p video
- five Mbps: sufficient for 480p video
As a broadcaster, yous can't control the net speed of your viewers. However, yous tin can watch your analytics data to figure out the speed of your viewer's connection. This can allow yous to modify your multi-bitrate streaming arroyo.
Encoder Configurations Related to Internet Speed
Agreement how bandwidth, bitrate, and video resolution connect on a more than tangible level helps broadcasters to better understand their internet speed requirements.
Permit'south take a look at how different bitrate settings correlate with different live streaming resolutions.
| ULD | LD | SD | HD | FHD | |
| Name | Ultra-Low Definition | Low Definition | Standard Definition | Loftier Definition | Full High Definition |
| Video Bitrate (kbps) | 350 | 350 – 800 | 800 – 1200 | 1200 – 1900 | 1900 – 4500 |
| Resolution Width (px) | 426 | 640 | 854 | 1280 | 1920 |
| Resolution Meridian (px) | 240 | 360 | 480 | 720 | 1080 |
| H.264 Profile | Main | Main | High | High | High |
As you can run across in the live encoder settings chart above, lower bitrate settings yield depression-resolution/low-quality streams, and higher bitrate settings yield high-resolution/high-quality streams. As nosotros mentioned, bitrate and resolution also directly correlate with bandwidth consumption, determining the necessary internet speeds.
It is condom to conclude that the college resolution yous aim for, the faster internet you will need.
Internet Speed Requirements for Unlike Streaming Use Cases
To circle back, your internet speed should be double your intended bandwidth usage. How much bandwidth you lot crave tin can be calculated in 1 of ii means. If y'all're doing multi-bitrate streaming, it will be the sum of the bitrates of each rendition you're streaming in. If you're merely streaming at a unmarried fleck rate, there's your terminal number.
As nosotros discussed, the required internet speed for streaming depends on each unique streaming setup.
From a technical standpoint, internet speed requirements direct depend on bandwidth needs. Bandwidth usage depends on bitrate settings and video resolution. The number of viewers you're streaming to and for how long y'all're streaming.
You tin can plug this information into a bandwidth calculator and double that number to notice your minimum internet speed for streaming. Allow's become through some specific internet speed requirements and set up suggestions for different streaming apply cases.
For reference, we're basing these suggestions based on the following estimated internet requirements for unlike resolutions:
- 1080p resolution stream @ v.v Mbps
- 720p resolution stream @ 2.ii Mbps
- 480p resolution stream @ 800 kbps
- 240p resolution stream @ 500 kbps
That said, let'south take a closer look at some real-life streaming scenarios.
Sports
Sports streaming is popular considering it allows fans to watch their favorite teams and athletes no matter where they are competing.
Professional sports broadcasting often is meant to accomplish a big audience. High-resolution video is a must since this type of streaming calls for a lifelike viewing experience. Y'all'll need a stable internet connexion with a speed of at least 5.5 Mbps. A tethered Ethernet connection would exist ideal since there is a lot of pressure on these Idiot box-grade streams.
Streaming a loftier school game, on the other manus, requires much less bandwidth, therefore, a slower internet connection would suffice. Take loftier school volleyball, for instance. The maximum roster is 12 students on each team, and so your potential fanbase is much smaller than a professional sporting event.
Education
Online video is very popular in teaching , specially when it comes to streaming classes and lectures. Standard definition streaming is sufficient for this type of stream since the video quality is not the priority, and so an internet connection with a speed of ~800 kbps will piece of work.
There are other types of educational streams that are unrelated to academia. Call back about other sorts of classes that people tin can participate in, similar fitness classes . Since visuals are important in this type of stream, fitness broadcasters might opt for higher bitrate streaming, so faster net would exist a must.
Regime
One of the most popular streaming uses for government agencies is for meeting transparency mandates. Basically, different municipalities live stream meetings that they are required to brand bachelor to constituents.
Music and Amusement
Concerts and music festivals are big events that are oft streamed in high resolution. It is common for result organizers to monetize these streams by charging a virtual admission fee.
When viewers pay for streams, there is a certain expectation. Viewers want a more lifelike experience, so high-quality streaming with low latency is a must. This means that cyberspace speeds capable of loftier-resolution streaming, at least 5.v Mbps, are a must.
Radio
Radio streaming is a fleck dissimilar than the other use cases we've discussed so far. Since radio is typically audio-only streaming, information technology consumes a smaller bandwidth, which means it doesn't need very fast internet.
Church
Churches utilise alive streaming for a plethora of use cases. The most common use of online video for churches is streaming services. Most church building community members are fine with average quality streams every bit long every bit the sermons and music are articulate.
A standard definition stream with an net speed of effectually 800 kbps should piece of work fine.
Chorus and choir performances and other church shows may require slightly faster net for church broadcasters that desire these streams to be higher resolution.
Net Speed Needed for Streaming on Different Platforms
Many broadcasters stream on social media streaming platforms in addition to the streams that they host with their white-label video players. The value of this is that it helps to accomplish an existing audience on a platform that they are familiar and comfortable with.
The recommended cyberspace speeds for streaming on some of the nigh popular live streaming platforms are as follows:
- Facebook : 4,000 kbps
- YouTube : 1,500 to 4,000 kbps
- Twitch : ii,500 to 4,000 kbps
- Dailymotion : 150% of the video bitrate
- LinkedIn Alive: ten Mbps
