What Upload Speed Is Needed for 1080p Video
There are many components that decide the quality of online video streams. One of these components is cyberspace speed. Different streaming setups require the back up of different internet connections. Some broadcasts require faster cyberspace than others due to several variables.
In this post, nosotros're going to hash out everything broadcasters need to know well-nigh internet speed for live streaming. We will cover the basics of internet speed for live streaming before we get into how to determine the best internet speed for your stream.
From there, we will discuss ideal net speeds for many different use cases. To wrap things up, we will discuss 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 technology, including streaming protocols, piece of work behind the scenes to deport chunks of data throughout the alive streaming setup to user-facing video players. Online video streaming requires an internet connexion that is steady and secure.
In that location are two measures of cyberspace speed: download speed and upload speed. As a broadcaster, you lot need to pay attention to the second office of your cyberspace connection speed: upload. In full general, our recommendation for alive streaming is that your upload speed should be at least double the total bandwidth you'll use.
The best type of internet connection for live streaming is Ethernet. This sort of connectedness is both stable and reliable. If Ethernet is not an option, WiFi is a close second. A wireless connexion can go the job done, but information technology is less reliable.
If neither Ethernet nor WiFi is available, cellular information is the terminal resort option. If cellular data is your online option, we recommend checking out our guide to remote streaming .
What is a Good Cyberspace Upload Speed for Live Streaming?
Many broadcasters are left wondering what the all-time cyberspace speed for alive streaming is. Nevertheless, that depends on several factors. Your internet speed should exist at least double the bandwidth that your stream volition use.
Different streaming scenarios have different technical requirements.
In general, an upload speed from 672 kbps to 61.5 Mbps will become the job done.
Conspicuously, this is a very wide range, so it is of import to evaluate your unique streaming needs to get a more than authentic answer.
In lodge to give you a ameliorate understanding of how this works on a technical level, let's rapidly pause down bandwidth and two related streaming metrics.
Video Bandwidth
Video bandwidth is the amount of information transferred during a stream. Bandwidth is important in dissemination for a few reasons. First, information technology affects what sort of internet speed you lot need. How much bandwidth you lot utilise as well affects your live streaming costs .
Your bandwidth usage is adamant by several factors, but the primary ii are video bitrate and video resolution. That'due south why higher-traffic, college-quality streams require more bandwidth.
Video Bitrate
Video bitrate is the amount of data that is transferred over a specific flow of time. It is often measured in bits per second or bps. Smaller files use kilobits per second or kbps.
Bitrate can exist 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'south prototype on the screen. In about scenarios, the more pixels a video contains, the college the quality of the video. More pixels can yield a clearer epitome.
Resolution measures a video's width by height in pixels. For instance, online content with a 1920 × 1080 video aspect ratio would measure out 1920 pixels forth the bottom and 1080 pixels in height.
College-resolution streams consume more than bandwidth, therefore college resolution videos require faster net. If you endeavour to stream a high-resolution video with a slow internet connexion, your stream may lag or become inclement.
Download Speeds for Viewing Live Streams
Streaming quality seems to have increased over the years, with video starting time failures down 33% twelvemonth-over-yr, buffering downwards 41%, and film quality upwards 25%. I of the reasons for this is the gradually increasing speed of net connections. Both mobile networks and home internet services are increasing in speed.
Remember how we discussed that in that location are two aspects of internet speed? As we mentioned, upload speed is important for broadcasting content, only download speed is of import when it comes to watching streaming video.
Today, the average download speed in the United States is around 99.3 Mbps.
Here are some general guidelines for internet speed and streaming video:
- 25 Mbps: sufficient for streaming 1080p HD video
- 10 Mbps: sufficient for 720p video
- v Mbps: sufficient for 480p video
As a broadcaster, you lot tin't control the internet speed of your viewers. However, you tin can watch your analytics information to figure out the speed of your viewer'due south connection. This tin allow you 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 net speed requirements.
Let's take a look at how dissimilar bitrate settings correlate with unlike live streaming resolutions.
| ULD | LD | SD | Hard disk | FHD | |
| Name | Ultra-Low Definition | Low Definition | Standard Definition | High Definition | Full Loftier Definition |
| Video Bitrate (kbps) | 350 | 350 – 800 | 800 – 1200 | 1200 – 1900 | 1900 – 4500 |
| Resolution Width (px) | 426 | 640 | 854 | 1280 | 1920 |
| Resolution Height (px) | 240 | 360 | 480 | 720 | 1080 |
| H.264 Profile | Primary | Master | High | High | Loftier |
As you can see in the live encoder settings chart in a higher place, lower bitrate settings yield depression-resolution/low-quality streams, and higher bitrate settings yield high-resolution/high-quality streams. As we mentioned, bitrate and resolution too directly correlate with bandwidth consumption, determining the necessary internet speeds.
Information technology is safe to conclude that the higher resolution you aim for, the faster net you will need.
Internet Speed Requirements for Different Streaming Apply Cases
To circle back, your cyberspace speed should be double your intended bandwidth usage. How much bandwidth y'all require can be calculated in one of two ways. If yous're doing multi-bitrate streaming, it will be the sum of the bitrates of each rendition you're streaming in. If y'all're only streaming at a single bit charge per unit, there'southward your concluding number.
As we discussed, the required net speed for streaming depends on each unique streaming setup.
From a technical standpoint, cyberspace speed requirements directly depend on bandwidth needs. Bandwidth usage depends on bitrate settings and video resolution. The number of viewers yous're streaming to and for how long you're streaming.
Yous can plug this information into a bandwidth calculator and double that number to find your minimum internet speed for streaming. Let's go through some specific internet speed requirements and set suggestions for different streaming use cases.
For reference, we're basing these suggestions based on the following estimated internet requirements for different resolutions:
- 1080p resolution stream @ 5.5 Mbps
- 720p resolution stream @ ii.2 Mbps
- 480p resolution stream @ 800 kbps
- 240p resolution stream @ 500 kbps
That said, let's accept a closer expect at some real-life streaming scenarios.
Sports
Sports streaming is popular because it allows fans to sentinel their favorite teams and athletes no matter where they are competing.
Professional person sports broadcasting frequently is meant to reach a big audience. High-resolution video is a must since this blazon of streaming calls for a lifelike viewing feel. You lot'll need a stable internet connexion with a speed of at least 5.v Mbps. A tethered Ethernet connexion would be platonic since at that place is a lot of pressure on these TV-grade streams.
Streaming a high school game, on the other hand, requires much less bandwidth, therefore, a slower internet connectedness would suffice. Have high school volleyball, for example. The maximum roster is 12 students on each squad, so your potential fanbase is much smaller than a professional sporting event.
Education
Online video is very popular in education , especially when information technology comes to streaming classes and lectures. Standard definition streaming is sufficient for this blazon of stream since the video quality is not the priority, and so an internet connection with a speed of ~800 kbps will work.
There are other types of educational streams that are unrelated to academia. Think about other sorts of classes that people can participate in, like fettle classes . Since visuals are important in this type of stream, fettle broadcasters might opt for higher bitrate streaming, so faster internet would be a must.
Authorities
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 available to constituents.
Music and Entertainment
Concerts and music festivals are large events that are oft streamed in high resolution. It is common for event organizers to monetize these streams by charging a virtual admission fee.
When viewers pay for streams, there is a sure expectation. Viewers want a more lifelike feel, so high-quality streaming with low latency is a must. This ways that net speeds capable of loftier-resolution streaming, at least 5.5 Mbps, are a must.
Radio
Radio streaming is a scrap different than the other employ cases we've discussed so far. Since radio is typically audio-just streaming, it consumes a smaller bandwidth, which means information technology doesn't need very fast net.
Church
Churches utilize live streaming for a plethora of use cases. The near common use of online video for churches is streaming services. About church building community members are fine with average quality streams as long as the sermons and music are clear.
A standard definition stream with an cyberspace speed of around 800 kbps should work fine.
Chorus and choir performances and other church shows may crave slightly faster internet for church broadcasters that desire these streams to exist higher resolution.
Internet Speed Needed for Streaming on Unlike Platforms
Many broadcasters stream on social media streaming platforms in add-on to the streams that they host with their white-characterization video players. The value of this is that it helps to reach an existing audience on a platform that they are familiar and comfortable with.
The recommended internet speeds for streaming on some of the most popular live streaming platforms are as follows:
- Facebook : 4,000 kbps
- YouTube : ane,500 to four,000 kbps
- Twitch : 2,500 to 4,000 kbps
- Dailymotion : 150% of the video bitrate
- LinkedIn Live: 10 Mbps
