The higher the bit rate, the larger the file size. The higher the bit rate, the higher the quality of the video. Sometimes you might want to compress the file to a lower bit rate to allow for faster file transfer. Remember that when you’re uploading files to YouTube or Dropbox, you don’t always want massive files. Recording at a lower bit rate can sometimes be just what you need if you want ease of file storage and file transferring.
VBR is generally a more efficient encoding method that results in smaller file sizes. When you export with VBR, you choose a target bit rate and a max bit rate. If you have a portion that has no movement or is just a black screen, the video will encode with a lower bit rate during that portion. If you choose to export with a Variable Bit Rate (VBR), your video bit rate will adjust depending on what is happening within your video. If you choose to export at 10Mbps, every second of your video will be just that: 10Mbps. If you choose to export with a Constant Bit Rate (CBR), your entire video will be your target bit rate, no matter what. When you are encoding/exporting a video file, there is an important difference to understand: Variable Bit Rate vs Constant Bit Rate. Hulu and Netflix are now pushing these limits as well, offering much higher bit rates for fast internet connections. BluRays are capable of holding much larger files, so they play videos at 24-40Mbps. DVDs played videos at a bit rate of 4-8Mbps. It is recommended to upload the highest bit rate version of your video – YouTube can’t increase the bit rate of your video.īecause of the development of technology over time, we now consume our content at much higher bit rates than in the past. This allows you to watch most videos no matter the strength of your internet. So if you upload a high bit rate video to YouTube and select to watch it back at 360p, YouTube will have already encoded a file for that size that has a bit rate in the. When you upload your videos to YouTube, the site automatically encodes your video to the ideal settings for each of the resolutions they offer. When you watch a video on YouTube at 1080p HD, the average bit rate of the video you are watching is 8-12Mbps. Bit Rate on YouTube and other Platformsīit rate is measured in megabits per second (Mbps). There are additional factors like sensor size that affect why these cameras have different looks, but bit rate is a large part of the equation. Even though all of these cameras can record 1920 x 1080 HD footage, they do not all look the same. Each camera has its own options for bit rates at which it can record. This is why an iPhone looks different than a GoPro and a DSLR. Not all cameras shoot at the same bit rate. The video on the right is much better quality, but it is over 5 times as large in file size. The video on the left has a much more pixelated, low quality image. Both shots are considered HD because they have a resolution of 1920 x 1080, however they are not equal. If we encode this video at two different bit rates, you will notice a difference in the quality. Take the same standard 1920 x 1080 HD shot. The 4K video must spread all of this data over a larger pixel area, thus compromising the look. If we kept the bit rate constant and shot two videos – one at 1080p and one at 4K – you would notice that the 1080p video might actually look better. But that is because cameras will generally record at a higher bit rate for these larger resolution files. Sure, when you have a higher resolution like 4K, you generally have a better looking video. It does not necessarily determine the quality of your video. Resolution is the pixel size of your video.
Many people confuse bit rate and resolution. More data per second, more space taken up.īit Rate is Not the Same Thing as Resolution As your bit rate goes up, so do the file sizes of the videos you are recording. If you shoot at a high bit rate, you must deal with large file sizes. The higher the bit rate, the higher the quality of your video. In reality, bit rate is none of these things.īit Rate is the amount of data encoded per second when you shoot video. You start throwing around terms like resolution, frame rate, HD, and it becomes a jumble of perplexity. Bit Rate can be a confusing topic when it comes to videography.
