More FPS means smoother playback but a bigger file.
Shutter speed is an in-camera setting used to determine the amount of motion blur in film production. The frame rate should not be used interchangeably with shutter speed. 24 is used in movies and 30 FPS on common on TV. A typical video can have 15 to 120 frames per second. The frames are presented usually at a constant rate called frame rate.įrame Rate: The number of frames (frame rate) presented on screen per second is represented as with FPS or frames per second.
720P VIDEO COMPRESS 1080P
A 1080p or full HD video will have frames of size 1080×1920 pixels with each pixel storing RGB (Red, Green, Blue) 8-bit color data and maybe some more. That’s why video is also called moving pictures.Ī frame behaves just like a photo, and all the attributes such as color depth and dimension. They are consecutively presented in such a manner as things appear moving on the screen. If you have any questions or suggestions, please reach out to our team.įrame: Any static picture you see on your screen while playing or pausing a video is called a frame. This guide purposefully hides complex details to simplify the understanding of most common terms and their usage. 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
720P VIDEO COMPRESS 720P
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.
