The conversion between different file formats is called transcoding.

Many digital cameras encode video natively, without needing to have any additional software post-processing and requiring less storage space. The process may happen in hardware or software. Just like getting an electric wire feed from the camera and storing the content in a. Since motion in scenes can drastically change in most videos, some encoders allow encoding at a variable bit rate by consuming more than average when needed and less when the scene is mostly static.Įncoding: Encoding is the process of digitization of analog video streams. Such as a landscape scene with little or no motion between frames. However, you usually won’t need that much space, thanks to compression and lossy encoding (quality compromise to save disk space) techniques.Ĭompression reduces the space required to store similar frames that have fewer moving parts. Many of our storage drives can’t even write to a disk that fast.
We are going to need around 540GB per hour for the raw footage. At 30 frames per second, a raw HD video will need 5MBx30 = 150MB storage space per second. The approximate size of each uncompressed frame is 5MB. 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.

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

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.
