Whats Better for Streaming? Upload or Download
In that location are many components that determine the quality of online video streams. 1 of these components is internet speed. Different streaming setups require the support of unlike internet connections. Some broadcasts require faster internet than others due to several variables.
In this post, we're going to hash out everything broadcasters need to know near internet speed for live streaming. Nosotros will cover the basics of internet speed for live streaming before we go into how to determine the all-time internet speed for your stream.
From there, we will talk over platonic internet speeds for many dissimilar use cases. To wrap things up, we volition discuss the importance of viewers' internet speed.

The Nuts of Cyberspace Speed for Live Streaming
A lot goes on behind the scenes to brand online streaming possible. Different types of technology, including streaming protocols, work behind the scenes to carry chunks of data throughout the live streaming setup to user-facing video players. Online video streaming requires an internet connection that is steady and secure.
At that place are two measures of internet speed: download speed and upload speed. As a broadcaster, yous need to pay attention to the second role of your net connection speed: upload. In general, our recommendation for live streaming is that your upload speed should be at to the lowest degree double the total bandwidth you'll use.
The best type of internet connexion for live streaming is Ethernet. This sort of connexion is both stable and reliable. If Ethernet is not an choice, WiFi is a close second. A wireless connection tin can get the chore done, but it is less reliable.
If neither Ethernet nor WiFi is available, cellular data is the last resort pick. If cellular data is your online option, we recommend checking out our guide to remote streaming .
What is a Proficient Internet Upload Speed for Alive 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 be at least double the bandwidth that your stream will utilize.
Dissimilar streaming scenarios take dissimilar technical requirements.
In general, an upload speed from 672 kbps to 61.five Mbps volition get the task done.
Clearly, this is a very wide range, and then information technology is important to evaluate your unique streaming needs to go a more than accurate respond.
In order to requite you lot a better agreement of how this works on a technical level, let'south quickly pause downwardly bandwidth and 2 related streaming metrics.
Video Bandwidth
Video bandwidth is the amount of data transferred during a stream. Bandwidth is important in dissemination for a few reasons. First, information technology affects what sort of internet speed you demand. How much bandwidth you use too affects your alive streaming costs .
Your bandwidth usage is determined by several factors, but the main two are video bitrate and video resolution. That'southward why college-traffic, higher-quality streams crave more bandwidth.
Video Bitrate
Video bitrate is the amount of data that is transferred over a specific period of time. It is ofttimes measured in $.25 per second or bps. Smaller files utilise kilobits per second or kbps.
Bitrate tin 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's image on the screen. In near scenarios, the more pixels a video contains, the higher the quality of the video. More than pixels can yield a clearer image.
Resolution measures a video'south width by height in pixels. For example, online content with a 1920 × 1080 video aspect ratio would measure 1920 pixels along the bottom and 1080 pixels in height.
Higher-resolution streams consume more bandwidth, therefore higher resolution videos require faster net. If you try to stream a high-resolution video with a slow net connection, your stream may lag or get choppy.
Download Speeds for Viewing Alive Streams
Streaming quality seems to take increased over the years, with video start failures down 33% year-over-twelvemonth, buffering down 41%, and movie quality up 25%. One of the reasons for this is the gradually increasing speed of internet connections. Both mobile networks and habitation cyberspace services are increasing in speed.
Remember how we discussed that at that place are 2 aspects of internet speed? As nosotros mentioned, upload speed is of import for broadcasting content, but download speed is important when information technology comes to watching streaming video.
Today, the average download speed in the United States is around 99.3 Mbps.
Hither are some full 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
Equally a broadcaster, you can't control the internet speed of your viewers. Notwithstanding, yous can watch your analytics information to figure out the speed of your viewer's connectedness. This can allow you lot to modify your multi-bitrate streaming approach.
Encoder Configurations Related to Cyberspace Speed
Understanding how bandwidth, bitrate, and video resolution connect on a more tangible level helps broadcasters to amend understand their internet speed requirements.
Let'south take a look at how different bitrate settings correlate with unlike live streaming resolutions.
| ULD | LD | SD | Hd | FHD | |
| Name | Ultra-Low Definition | Low Definition | Standard Definition | High 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 | Principal | Loftier | High | High |
As you can see in the live encoder settings chart higher up, lower bitrate settings yield low-resolution/low-quality streams, and higher bitrate settings yield high-resolution/high-quality streams. Equally we mentioned, bitrate and resolution also direct correlate with bandwidth consumption, determining the necessary internet speeds.
It is safe to conclude that the college resolution y'all aim for, the faster internet y'all will demand.
Internet Speed Requirements for Different Streaming Use Cases
To circle back, your internet speed should exist double your intended bandwidth usage. How much bandwidth you require tin be calculated in one of ii means. If you're doing multi-bitrate streaming, it will be the sum of the bitrates of each rendition yous're streaming in. If you lot're only streaming at a single bit rate, there'due south your concluding number.
As we 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 lot're streaming to and for how long y'all're streaming.
Yous can plug this information into a bandwidth figurer and double that number to discover your minimum internet speed for streaming. Let's become through some specific internet speed requirements and prepare up suggestions for different streaming use cases.
For reference, we're basing these suggestions based on the post-obit estimated net requirements for different resolutions:
- 1080p resolution stream @ five.5 Mbps
- 720p resolution stream @ two.ii Mbps
- 480p resolution stream @ 800 kbps
- 240p resolution stream @ 500 kbps
That said, let's have a closer look at some real-life streaming scenarios.
Sports
Sports streaming is pop considering it allows fans to watch their favorite teams and athletes no matter where they are competing.
Professional person sports dissemination ofttimes is meant to reach a large audience. High-resolution video is a must since this type of streaming calls for a lifelike viewing experience. You'll demand a stable internet connection with a speed of at least 5.five Mbps. A tethered Ethernet connectedness would be ideal since at that place is a lot of pressure on these Television-form streams.
Streaming a loftier school game, on the other hand, requires much less bandwidth, therefore, a slower internet connectedness would suffice. Accept high schoolhouse volleyball, for instance. The maximum roster is 12 students on each team, and so your potential fanbase is much smaller than a professional person sporting event.
Educational activity
Online video is very pop in instruction , especially 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 then an net connexion with a speed of ~800 kbps volition work.
There are other types of educational streams that are unrelated to academia. Call up virtually other sorts of classes that people can participate in, like fitness classes . Since visuals are important in this blazon of stream, fitness broadcasters might opt for college bitrate streaming, and then faster internet would be a must.
Government
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 big events that are often streamed in loftier resolution. Information technology is common for result 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 loftier-quality streaming with depression latency is a must. This means that cyberspace speeds capable of high-resolution streaming, at least v.5 Mbps, are a must.
Radio
Radio streaming is a fleck unlike than the other use cases we've discussed and so far. Since radio is typically audio-only streaming, it consumes a smaller bandwidth, which means it doesn't need very fast internet.
Church
Churches use live streaming for a plethora of utilize cases. The most common utilise of online video for churches is streaming services. Most church community members are fine with boilerplate quality streams every bit long as the sermons and music are articulate.
A standard definition stream with an internet speed of effectually 800 kbps should piece of work fine.
Chorus and choir performances and other church shows may require slightly faster internet for church broadcasters that want these streams to be higher resolution.
Internet 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 attain 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 : four,000 kbps
- YouTube : 1,500 to 4,000 kbps
- Twitch : 2,500 to four,000 kbps
- Dailymotion : 150% of the video bitrate
- LinkedIn Live: 10 Mbps
Final Thoughts
