Does Upload in Hd Refer to Live Feed or Phone Camera Video
Choosing the best live streaming settings for your platform is vital to a successful alive video.
Amongst the many technical aspects surrounding live streaming, in that location are a few things every streamer should at present exist able to cull the all-time live streaming settings for Facebook, YouTube, Twitch and any other platform. The best settings for alive streaming are not necessarily the highest quality settings. Apart from the video quality, when it comes to live streaming, bitrates, encoding and latency are simply every bit important.
Agreement Live Streaming Settings
Before you can decide the best live streaming settings for your live videos, you demand to know what goes into it. These are a few technical aspects of alive streaming of which every streamer should be aware.

Video quality
Video quality is one of the most of import aspects of video in general. Within video quality, there are 2 things we need to focus on: resolution and frame charge per unit. The resolution is the size of the video on the screen in pixels. One example of a high resolution would exist 1080p, which means the screen will be 1920×1080 pixels. We also refer to them as HD (high-definition), SD (standard-definition), and 4K, which is an ultra-loftier-definition video (2160p).
A video is, in fact, several all the same images in a sequence. Each image in this sequence is called a frame. So, if the frame rate of a video is 30 fps (frames per 2nd), it means that each second has xxx images. The more than frames you accept, the smoother the video will be. When you take a low frame rate, like 15 fps, your video will be choppy. Ideally, you should effort to stream at a college frame rate (30 fps). If you lot desire a cinematic look, you can go for the 24 fps which is the frame rate many movies are shot at.
Higher resolution volition require a higher bitrate and the college frame rate takes more from your hardware.
Bitrate – Net speed
You have a certain amount of bachelor net bandwidth and part of that is dedicated to uploading. You can run a test at Speedtest.cyberspace and find out your upload speed. Bitrates refer to how much data is sent through your live stream. It's as if the $.25 "carry" the information from your video to the platform. So, higher resolutions demand higher bitrates.
Your video bitrate and your sound bitrate should ever be 20% lower than your upload speed, to continue your live stream stable. If you accept 10 Mbps upload speed, your video and audio should exist less than eight Mbps. But, keep in mind that college resolutions will also demand more from the figurer.
Always test things before going live, to brand certain you're putting out quality and stable stream. Many live streaming applications already come up with presets, so you don't need to be an adept at bitrates, but information technology's important to know what it is.
Encoding & Latency
Encoding is basically taking the video information in this specific format and translating it to a different one, that the alive streaming platform understands. An encoder software, like ManyCam, unremarkably has presets to assistance you determine your encoding power. Some will say, from slow to very fast, others might call information technology high quality or loftier speed. Regardless of the name, these presets can help y'all attain the quality live stream you want.
The faster the encoding is, the less quality your video will have but the easier it will be to acquit out the information. When you choose a slower encoding preset, you volition get a improve quality simply with a bigger delay betwixt what the camera captures and what the viewers see.
Apart from the settings in the software, you can also prepare your alive streaming platform. YouTube refers to this filibuster as live streaming latency. If you want real-fourth dimension interaction with your viewers, lower latency is a amend option, but they might experience more than playback buffering. On the other manus, if this isn't your priority, a normal latency volition reduce the buffering.
Platforms and Live Streaming Settings
Each platform has its own specifications. Although they might be like, it's important to know what's different betwixt them to make certain your live streams are stable and have good quality.
Best Live Streaming Settings for Facebook
Here are the video format guidelines recommended for Facebook Alive:
- Recommended max Facebook bitrate is 4000 Kbps (four Mbps).
- Max resolution: 1080p (1920×1080) resolution, at 60 fps.
- An I-frame (keyframe) must be sent at to the lowest degree every 2 seconds throughout the stream.
- Titles must have fewer than 255 characters or the stream will fail.
- H264 encoded video and AAC encoded audio-only.

When compared to YouTube or Twitch, Facebook has a lower quality streaming. The maximum video resolution accustomed by Facebook is 1080p, while on YouTube you tin have resolutions as loftier as 4K / 2160p.
Although these are Facebook's recommended settings, they might not be the best alive streaming settings for y'all. It depends on the equipment yous have at hand and your internet speed. To achieve a good quality live stream, you have to run a few tests and encounter what works best for your setup.
Facebook Live stream latency
For example, try streaming at a lower quality and see how your video turns out. Here, it'south of import to analyze the end quality of your stream and the delay between what your camera is capturing and what's displayed to the viewers (latency). You might exist able to get abroad with a lower quality video considering it will "travel" faster through your connection and your viewers will take a more than existent-time experience.
Only, if you lot need to show images and videos in higher quality, then you lot will need your internet speed to keep upward with your alive stream. Even with great bandwidth, delays can happen. You might go a bit more latency, which is not necessarily a bad affair. All information technology means is the experience will not be as existent-time as with lower latency. The advantage here is, it reduces viewers playback buffering.
Best Live Streaming Settings for YouTube
For well-nigh people, the optimal YouTube live stream settings look like this:
- Resolution: 1080p (1920x1080p)
- FPS: 30 fps or lx fps
- Video bitrate between iii,000 and half-dozen,000 Kbps.
Hither is the full list of YouTube's all-time alive streaming settings:
Resolutions
- 4K / 2160p (3840x2160p) at 60 fps or thirty fps
- 1440p (2560x1440p) at sixty fps or thirty fps
- 1080p (1920x1080p) at lx fps or thirty fps
- 720p (1280x720p) at 60 fps or xxx fps
- Or lower.
YouTube streaming bitrate
The suggested streaming bitrate will increase according to the resolution and FPS of your live video. For instance:
- 4k videos at threescore fps: 20,000 – 51,000 Kbps
- 4k videos at 30 fps: 13,000 – 34,000 Kbps
- 1440p videos at 60 fps: ix,000 – 18,000 Kbps
- 1440p videos at 30 fps: 6,000 – 13,000 Kbps
- 1080p videos at threescore fps: four,500 – 9,000 Kbps
- 1080p videos at xxx fps: 3,000 – half dozen,000 Kbps
The best YouYube bitrate settings for your stream tin can vary greatly because information technology relies on many factors. If you are unsure of the best bitrate for your stream, yous tin can leverage a live encoder software such as ManyCam, which can define it automatically for you to achieve the best possible quality.
