Upload Speed for Streaming Twitch Encoder X264 3mb
Streaming video resolution is a very important metric for live streaming. It contributes to the quality of a video stream which plays a huge role in the user experience.
To achieve the desired streaming resolution settings, broadcasters must get familiar with encoders and their various settings.
Encoders include a wide range of settings for video resolution quality, frame rate, audio bitrate, and other variables, also every bit protocol, bitrate encoding type, pixel attribute ratio , and then on. With all of this in mind, you're likely wondering what are the best streaming resolution settings.
In this post, we will hash out the best resolution for streaming for loftier-quality live streaming. We'll also cover what an encoder is, how encoder settings relate to cyberspace speed, and other suggested encoder settings for streaming.

What is Video Streaming Resolution?
Streaming resolution is the measurement of your video width by height, and it is measured in pixels. For instance, a video with a 2560 10 1440 attribute ratio would measure out 2560 pixels along the bottom and 1440 pixels in height. This measurement is also called "spatial resolution."
When discussing video streaming resolution, information technology'due south important to acknowledge the departure between progressive and interlaced, which determines how the pixels are displayed on the screen. Progressive videos produce a more fluid image, and interlaced videos appear more "pixelated."
Oft, video streaming resolution is called out by only the height of the video. Continuing the example from above, a stream with a resolution of 2560 x 1440 would be simply referred to as "1440p" or "1440i." In these resolution examples "p" stands for "progressive," and"i" stands for "interlaced."
The Best Resolution for Live Streaming
When it comes to live streaming , it is typically believed that college video resolution equates to a better quality viewing experience on any given live streaming platform . However, this is not entirely truthful.
Live streaming requires a trade-off between video quality and speed. This has to do with the fact that a higher resolution also requires higher bandwidth to stream the video finer.
The 2 nearly common streaming resolution settings are:
- Standard definition at 720 ten 480 pixels (480p)
- High definition at 1920 10 1080 pixels (1080p)
In practice, this unremarkably gets sampled down to a somewhat lower resolution, 640 ten 360 pixels (360p), or smaller.
Please keep in mind that virtually resolutions are communicated based on their height, which is why it'southward common to see HD TVs billed every bit 1080p.
It'due south always necessary to consider information charge per unit and resolution together, as 1 limits the other. Streaming at a higher information charge per unit allows college resolution.
It's likewise of import to consider the download charge per unit for viewers. For high-definition streaming , all of your viewers should take an constructive download rate of at least 5 Mbps.
College bandwidth is a good idea. This is all possible with high-speed internet connections, which typically run at over 100 Mbps.
Most encoders allow settings of 1080p, 720p, 480p, 360p and 240p (peak) and corresponding width. Setting this to the highest resolution that your net can handle allows recipients to view the video in the all-time streaming resolution quality without buffering.
Information technology'due south possible to broadcast simultaneously in SD and HD , simply this requires sending ii streams to your host service. It does not affect the download bandwidth requirement but does require more upload speed than a single transmission.
What is an Encoder and What Does it Do?
An encoder is an essential tool for professional person live streaming. It takes the RAW video files from your camera and converts them to files suitable for streaming over the cyberspace.
At that place are both hardware and software encoders. Each of these options come with their own pros and cons. Generally, software encoders are much cheaper and easier to use. On the other manus, hardware encoders are dedicated devices, and then they tend to be better at their job.
Nosotros recommend starting with a free encoder, such as OBS Studio, to familiarize yourself with the different encoding features before making a larger investment in an encoder with advanced capabilities.
Equally nosotros mentioned, the settings that we review in this post are specifically for H.264 encoding. H.264 is the optimal codec for alive video streaming, and so nosotros volition be talking about encoders that are compatible with video streaming protocols.
Choosing Encoder Settings Based on Internet Speed
The average download speed in the The states varies widely past state. Even within i state, individuals likely have different alive streaming internet speeds depending on their service for net connection.
It is important to proceed in heed that many people will view your broadcast from free WiFi connections or over cellular data on their smartphones. Those tend to exist a scrap slower than loftier-speed home connections.
Yous should be streaming with the video resolution and other encoder settings that will work best for the upload and download speed that your viewers have access to. To make up one's mind which settings are best, you should identify where your viewers alive and what kind of connection and hardware they'll exist using.
However, if you lot know that your audience has the technical ability to handle Hard disk drive quality broadcasting, it'due south likewise a good idea to know what settings volition optimize that experience for them.
Suggested Streaming Resolution and Bitrate Settings for Different Video Qualities
To control the quality of your video, you're going to need to choose the proper combination of streaming resolution and bitrate settings.
Here are the suggested streaming resolutions settings for ultra-depression definition, low definition, standard definition, high definition, and full loftier definition. As yous volition run into, nosotros've besides listed the video bitrates and H.246 profile that corresponds with each resolution.
| ULD | LD | SD | HD | FHD | |
|---|---|---|---|---|---|
| Name | Ultra-Low Definition | Low Definition | Standard Definition | High Definition | Total 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 | Principal | Main | High | High | High |
Other Recommended Encoder Settings
Streaming resolution is but ane of many encoder settings that broadcasters can utilize to command the quality of your live stream.
We'd similar to point out that there's no definitive set of "best" encoder settings for alive streaming. However, your choices are limited not but by your ain upload bandwidth but likewise by the connection speed available to your viewers.
That said, here is an overview of some of the suggested encoder settings for loftier-quality live streaming.
Bitrate Settings
Bitrate refers to the rate of information manual. The main affair to keep in listen is that you need a higher bitrate setting to finer broadcast at a higher definition and frame rate. Transmitting HD video at a depression bitrate is pointless since the transmission speed won't allow the high quality you're looking for.
For video bitrates , you take to walk a tightrope betwixt video quality and user experience. There is a hack to navigate this effect with grace.
Multi-bitrate streaming allows you to stream at different bitrates so that users with different cyberspace speeds tin admission the optimal file size.
For example, you lot tin stream in high definition at 2MB per 2nd alongside a standard definition 500kbps feed. That way you can cater to both an optimal quality and optimal user experience, depending on their connexion speed.
Withal, please note that multi-bitrate streaming requires a very fast upload speed. You'll want to make sure your upload speed is double the total bitrate you programme to stream at. Another general rule of thumb is to allow for an adaptive bitrate and offer your bitrate at something lower than 1MB per 2nd if yous are but doing a single bitrate stream.
Frame Rate Settings
Videos may look like smoothen moving images, but they are actually a series of however shots that are presented to your optics at a rapid speed, to create the illusion of move.
That is where the other main variable setting, frame rate , comes into play. Frame charge per unit is the number of "frames," or all the same images, that are transmitted each second, and information technology is measured in frames per second (fps).
Every bit with streaming resolution, there's a trade-off between college frame rates , which improve video quality, and college video bandwidth requirements.
Most streaming video today has a frame rate of 24 fps or college, with video running at lx fps is at the very high end and rarely used. Dropping it much beneath 24 fps results in meaning choppiness especially when fast movement is shown.
That said, thirty fps is the standard, which is often called a full-frame. This is the general frame rate seen for a lot of televised content. Therefore 30 fps works equally a expert base of operations, and if the motility does non look every bit smoothen every bit desired, it can exist slowly adjusted until the playback is optimal.
You can utilise a feature called "variable bitrate streaming" to adjust the rate automatically to accept the best epitome even if a lot is happening on the screen.
A related setting is keyframe frequency or keyframe interval. This should be set to two or 3 seconds in every scenario.
Additional Encoder Settings
Besides resolution and frame rate, your encoding software allows you to choose the streaming protocol, video codec , audio codec , and other parameters for how the video and audio content is encoded and broadcast.
Most of these other settings don't affect video quality or bandwidth requirements in the same fashion as resolution and frame rate. Instead, they should be prepare to any your video platform requires.

Conclusion
Setting up your encoder with the all-time streaming resolution may seem a little daunting at starting time, simply information technology shouldn't be. There are two main things to remember.
One is the trade-off between video quality (as determined by resolution and frame rate) and required bandwidth for both upload and download streaming. The other thing to keep in heed is your streaming platform and any encoding requirements for that software.
Once you have the settings figured out and tested, you can leave them lonely unless something significant changes.
Equally we mentioned, gratis encoding software is your best bet if you lot are new to professional broadcasting. We recommend the OBS Studio version that is customized to integrate seamlessly with the Dacast streaming solution.
