There can be high-resolution videos with low bitrate and low resolution videos at very high video bitrate. Pixels define the resolution of the video, while bitrate is average data size for a video file expressed per second of video. Though as I already mentioned different service providers can offer different pixels even at the same video bitrate. For the same streaming provider the higher the pixels, the higher the bitrate, and vice-versa.
There is no precise technical relation between pixels and bitrate. What is the relation between pixels(p) and video bitrate (kbps)? Similarly, a 1000 kbps 1 hour video will be 450 MB in size , 600 kbps will be 270 MB in size. So, the size of a 1hour 1500 kbps video will be – 1500*60*60 -kilobits= 1500*60*60/8000 MBs of data = 675 MB per hour of video data. How is video bitrate linked to the size of the video?īitrate is generally represented by kbps which essentially means kb (kilobits) of data per second. So, I hope that answers what is bitrate in the video. A good looking video consists of a high video bitrate along with a high video resolution and framerate.
A high video bitrate is one of the most vital factors in the quality of a video. Video bitrate is the video data transferred at a particular time. Vdocipher helps several video Platform to host their videos securely, helping them to boost their video revenues. Please read the next section to understand bitrate as a quality index. So, the next obvious question is what exactly determines the video size? It is video bitrate (generally represented by kbps like 1500 kbps etc).

It is even possible that say 1 hour, 1080p video of vdocipher is of lower size than 720 p of Vimeo. Thus, Youtube, Vimeo and Vdocipher can provide different size of videos for the same length and same pixel quality. But how much of data is captured in video, is not determined by number of pixels exactly. If pixel quality is fixed, then the number pixels in a video is fixed. Surprisingly there is no fixed answer to that. Does pixel directly correspond to a size? What will be the size of 1 hour,1080 p video? So, until you know the aspect ratio, you cant determine the exact number of pixels in a video. Though this may vary if the aspect ratio of video is different (like 4:3). Similarly, 480 p will mean 480 pixels in height and 480*16/9 -853 pixels as width of video. So, in common convention 1080p means 1080 pixels as the height of video and 1920 as the width of video. Thus the width of video becomes 1080*16/9 – 1920 pixels. Now the next question is what is the width of video? There is no exact technically right answer but in common convention, the video is 16:9 for online playback. Thus, a video quality at 1080p means – the height of video is 1080 pixels. Pixels as a quality index essentially mean the height of video in number of pixels.
