![]() There are a lot of other factors influence the actual video file size such as compression ratio, variable bitrate, color depth.Īlthough the original intent to write about video file size, read along if you would like to learn more about videos, overall. The above table is for heuristic estimation and reference only. Here is a reference chart taken from sample videos found on Youtube/internet Resolution And if your video contains audio? That track has its own bitrate as well.įile Size = Bitrate x duration x compression ratio However, in this instance, the 4k video quality would appear poor but take less space on the disk when compared to a 720p video. Technically-speaking, you can have a 4K video with a lower bitrate than a 720p video. Video file size depends on the bitrate but not the video resolution.īitrate is the most important factor in determining a video file size. In order to get the most accurate calculation, we need to start by dispelling a common myth: ![]() How large is the one you just recorded? This complex storage format holds a lot of information and there are many reasons why you may want to check the size of it. ![]()
