Then you are confused about what is bitrate exactly? Is there anything to do with my video quality? Don't worry. In fact, there are so many readers like you who have these doubts too.
In this article, we will let you know what is video bitrate, the relationship between video bitrate and quality. In the end, we will give you a bonus about how to change video bitrate. Continue reading! Bitrate is the number of bits per second. Video bitrate affects video quality in several ways. First, it is the key measure of any video file size. Secondly, high video bitrate results in high video quality, and low bitrates result in poor video quality.
However, using an extremely high bitrate is just a waste of bandwidth. In general, a higher bitrate will accommodate higher image quality in the video output, only when comparing the same video with the same resolution. Bitrates should be expected to go up whenever the resolution goes up, as more data is being processed.
Therefore, high video bitrate may provide excellent quality, but it can also place a major strain on your hardware which can result in stutters. A bit is defined as the smallest amount of data on a computer. For more information about choosing the right resolution, read our video resolution guide right here! Conclusion: x p is a good resolution for first-time streamers.
While bitrate and resolution determine how good your video looks, your framerate governs how smooth it appears. For fast-paced action games like that, you might consider a 60 fps stream. On the flipside, single-player games like The Last of Us Part II are slower-paced but have detailed environments that look perfectly fine at 30 fps.
Why is this important to know? Well, your framerate will work in tandem with your bitrate — and you may have to sacrifice resolution for a larger framerate. If you do have to choose between framerate and resolution, go with whatever you think is more important, but here are a few simple examples to help you out.
PUBG often features enemies off in the distance , so a sacrificing framerate for a higher resolution like p at 30fps might be the way to go.
Meanwhile, Tekken 7 features large, fast-moving character models , so dropping your stream down to p at 60 fps makes sense. Conclusion: 60 fps streams look great, but 30 fps is good when starting out. 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. But in practice, platforms might reject your video mid-stream, or struggle to transcode it on the fly which causes the video to appear jerky.
So you know your upload speed and the limits of what it can do — what now? Recommended upload speed: 6. Recommended upload speed: 5. Recommended upload: 5. Recommended upload speed: 4. Recommended upload speed: 3. One thing that comes up in nearly every stream setup guide is that being a good streamer is about finding balance.
How powerful is your streaming PC? How fast is your internet? Was it a super expensive cinema camera from Arri or RED? Chances are, the footage came from a DSLR, camcorder, screen recording, or even modern smartphones.
At p, you should export any video intended for upload onto YouTube at a bitrate of 8 Mbps. This is a sweet spot of good quality with very low file size. If your p video is at a higher frame rate like 60 frames per second fps , bump up the bitrate to 12 Mbps. Since there are more actual frames shown for every second of footage which achieves that buttery smooth slow motion , you have to allow more data written into the file to maintain the same quality as a video with a lower frame rate.
Those that are savvy with internet streaming speeds might notice that these bitrates are higher than what most users will be able to watch with an average internet connection. So why would YouTube ask for a file that is too heavy to deliver to most of its audience? These services all have powerful, built-in video compression algorithms that take whatever you upload and create many versions from your source file.
This is known as adaptive bitrate streaming. YouTube really helps us out and does most of the heavy lifting in calculating the best bitrate for a given internet connection, device, and viewer. As a content creator, it is your job to supply a good quality source file that can be compressed by the algorithms and still maintain its integrity.
For example, if you exported a p video at 2 Mbps, all versions created by YouTube would suffer in quality because there is less initial data provided in the file to analyze and compress. A common question up for debate is since YouTube and other platforms compress our videos anyway, why not just upload a massive, high-quality file? You certainly can! The streaming giants even accept the aforementioned professional formats like ProRes and DNxHD, and these can be a good choice if you are hyper-focused on quality.
Just be warned that upload and processing times will increase dramatically, and these files will take up way more digital real estate on both your hard drive and cloud accounts. While most of today's popular online platforms work with similar compression algorithms, not every video is destined for online use in this way. If you are hosting a video on your own website server or delivering a video to a client, it is best to ask for the specific settings they want. When working with commercial clients or agencies, it is common practice to create and deliver both a ProRes high-quality master file and an MP4 web-friendly file ready to upload.
If you are working with a p video, which is smaller than p, YouTube suggests a bitrate of 5 Mbps. This is because everything is happening live!
A video and audio stream is uploaded from your device to an intermediary platform such as the Amazon-owned streaming giant, Twitch. This stream is passed on to viewers who tap into your feed. Normally, once a video is finished and ready to export, it is a good time to sit back and grab a cup of coffee while your computer gets to work crunching the file. This means your computer, specifically the CPU chip, has to work constantly to process and encode the media.
Additionally, your internet bandwidth must be capable of constantly uploading the stream. The higher the bitrate, the harder your CPU has to work to keep up.
This handy page from Twitch is a great reference to get started with streaming settings for your particular setup. Higher frame rates and bigger resolutions need more bitrate to keep up with quality, just like working with regular video files. A very high-quality stream is generally p at 60 fps. This resolution and high frame rate require a higher bitrate and more encoding power.
