On the higher end is 1080 (1920 × 1080) which is considered Full HD, and it requires more processing power, a bigger share of your nitrate, and could make your video appear choppy to viewers if you don’t have the bandwidth. While nitrate and resolution determine how good your video looks, your frame rate governs how smooth it appears.
Let’s take a shooter like Call of Duty: War zone, which has an unlocked frame rate on PC and runs in excess of 60 frames per second (fps). PUBG often features enemies off in the distance, so a sacrificing frame rate for a higher resolution like 1080p at 30fps might be the way to go.
The problem is that not every platform (such as Twitch) lets viewers change resolutions unless the streamer is a Partner and has platform-side transcoding. Being able to see enemies at a distance in PUBG is a good reason to up the resolution for your viewersAlso, if you’re streaming a multiplayer game you’ll need some leftover bandwidth, or you’ll experience in-game lag, so make sure you leave at least 2 Mbps spare for multiplayer gaming.
Recommended upload speed: 3.5–5 Mbps Resolution: 640 × 480 Nitrate: 1500 to 2500 KBS Frame rate: 60 fps One thing that comes up in nearly every stream setup guide is that being a good streamer is about finding balance.

We get a lot of questions about how to find the optimal resolution to nitrate ratio. Depending on your encoder, video content, audience, and streaming destination, your resolution and nitrate will likely be different.
To best determine the optimal ratio for your stream, let’s first define what resolutions and nitrates are and how they affect video quality. It won’t inhibit the video quality, but since the monitor can only see 720 pixels, anything beyond that is wasted bandwidth.
Nitrate is the amount of data encoded for a unit of time, and for streaming is usually referenced in megabits per second (Mbps) for video, and in kilo bits per second (KBS) for audio. If you have a download speed of 5 Mbps and you are watching a stream at 6 Mbps, the viewing experience will be choppy, and you’ll probably get stuck in buffering limbo because your connection can’t keep up with the amount of information being sent on the stream.
You must evaluate your network connection to determine whether it is strong enough to support your stream at your desired resolution. If your available bandwidth isn’t robust enough to support streaming at your desired resolution and nitrate, you can use network bonding to combine bandwidth from multiple internet sources into a single, stronger connection.
By connecting your compatible encoder with Trade’s cloud stream management platforms, Core or Share link, you can bond network connections from Ethernet, Wi-Fi, cellular modems, and even mobile phones to overcome bandwidth restrictions on the encoder side. Finally, if you have limited bandwidth at your broadcast site, but your encoder is capable of streaming with a more efficient video codec like HEC / H.265 instead of just H.264, you can send out a lower nitrate HEC stream from your encoder and have it transcoded to H.264 in the cloud for final delivery to streaming destinations and viewers.
Cloud transcoding can help those watching with slower connections or on mobile devices with data limits because it enables the single stream sent out from your encoder to be converted into several lower resolutions and lower nitrate streams that the viewers can choose instead of each viewer receiving the same higher resolution / higher nitrate stream. More dynamic content requires higher nitrates to have good quality, so you will need a higher nitrate to stream sporting events or video game competitions as opposed to speakers giving presentations at a conference or commencement ceremonies.
Keep in mind that every streaming platform comes with different presets which may limit the video nitrate and resolution combinations they will accept. Technically, nitrate means the quantity of data required for your encoder to transmit video or audio in one single second.
In livestreaming, Mbps is the most common nitrate unit for videos and KBS for audio. CBR encoding optimizes media files, saves storage space and prevents hiccup playbacks.
It is recommended for streaming videos with constant frames and similar motion levels like news reports, for example. This type of nitrate is ideal for dynamic video contents such as music concerts or sports events.
Another essential term to know about nitrate is “pass.” Passes define how many times your codec analyzes the video before deciding how to compress it. The more passes you set up in your codec, the better the image quality is while retaining the same file size.
Nitrates directly affect the file size and quality of your video. Nitrates also help you determine the internet connection speed you need to be able to watch.
It also helps you decide how much it is going to cost for your bandwidth to host the video on your site and deliver to your audience. A higher nitrate results in smoother streams and larger video file sizes.
If your encoder and computer have limited capacity, high nitrates could cause video buffering. On the other hand, uploading low nitrates is not an ideal choice, since it produces worse-quality and unprofessional streams to your viewers.
You need to consider the accessibility of your stream, the power of your encoder, the specifications of your computer, the number and location of your viewers, and your video configurations. If your video has a high nitrate, you need to consider whether your potential audience will be able to view it, depending on their location and internet connection.
The higher the nitrate is and the more people visiting your site, the more bandwidth you will need to ensure smooth video streams. However, the good news is video published platforms have their nitrate recommendations to which you can refer.
YouTube has their list of recommended upload encoding settings, including nitrates. A general tip for streaming on YouTube is to render a high-bitrate video so that when they compress it, you will have multiple playback options.
Facebook suggests that you use a wired internet connection instead of wireless to maintain video stability throughout your streams. Fortunately, most advanced video editing programs have the presets according to your preferred device.
Nitrate refers to the quantity of data required for your encoder to transmit video or audio in one single second. Nitrates directly affect the file size and quality of your video.
Depending on your encoder’s capacity, choose a balanced nitrate number for your video. Keys to consider while choosing a nitrate: resolution, frame rate, video accessibility, and cost of delivery.
One thing that you will encounter when recording a gameplay either in OBS (Open Broadcaster Software) or from an Plato capture card (HD60 S, HD60 S+, 4K60 S+, 4K60 PRO), even in Aver Media, there is this nitrate that makes you clueless on what it is for. However, you can find a better nitrate settings that produces unnoticeable changes from high quality with reduce file size.

For example, if you’re using 100,000Kbit/s nitrate, you need to make sure that your storage device write speed is above 100 MB/s, or else, it will have problem transferring files and data corruption.
