![]() You undoubtedly know them: milli-, centi-, kilo-, mega-, and giga- are all metric prefixes. Metric prefixes always have a numerical value of 10ⁿ (so 10, 100, 1000, and so on). The whole confusion stems from mixing up two types of unit prefixes: metric and binary. Each prefix has a fixed numerical value: for instance, kilo- refers to a thousand (so one kilogram is equal to a thousand grams), and mega- refers to a million (so one megapixel consists of a million pixels. It is the word that stands just before the unit name – for example, kilo- or mega. Which one is true?īefore answering this question, let's clarify what a unit prefix is. In the first version, one kilobyte is the equivalent of 1000 bytes, and in the second – of 1024 bytes. You've undoubtedly heard two contradictory stories. If you're not an expert on data size, you are probably perplexed by the conversion between different units. Visit our byte conversion calculator to learn mo The file size is expressed in data size units, such as bytes, kilobytes, or megabytes. N is obtained by multiplying these two values, so finally, you can arrive at the following formula for video file size:įile size = duration × frame rate × frame size It usually ranges from 12 fps for animation through 24 fps for regular movies to even 60 fps. ![]() The frame rate is the number of frames per second ( fps) of the video. To calculate the value of N, you need two pieces of information: the duration of the video and its frame rate. Where N is the number of frames in a video. It means that we can find the total file size using: If you want to calculate the video file size, you need to sum up the data size of each of these digital still images. Each frame is shown on the screen for a very short time (for example, 1/24 of a second), which makes the images appear to blend together. These still images are called video frames. Review Other Links section as each format has it’s own Encoder Options.Every video comprises a series of still images, presented one after another to create a moving picture. Once you are finished, click the Convert button and save your file to your desired folder.You may want to experiment to find the lowest acceptable frame rate of your video file. Lowering the frame rate of your video to 15 or 10 fps can reduce the file size by as much as 200% or 300%. The lower the Frame Rate, the smaller the File Size. Use the up and down arrow to adjust the frames per second. Check Limit Frame Rate under Video Output Options. Reduce Frame Rate to reduce video file size.Check the Constrain Proportions checkbox to avoid distortion. ![]() Enter a smaller width and height to achieve a smaller file size. ![]() Click Video Output Options tab under File Options and check the Resize Video checkbox. Resize Video Dimensions can also reduce the video file size.You can also select your desired Video Quality and Filesize. The lower the bitrate, the smaller the file size but the output quality will also be lowered. The bitrate affects the file size of your video output as well as its quality. Click File Options and click the down arrow beside Video Quality/Bitrate under MP4 Encoding Settings.Ĭhange the video Bitrates to a lower kbps value. Another way to reduce your Video File size is by reducing Video Quality/Bitrate.Note: The Output Format used in this tutorial is the same as the format of the original file. H.265 offers from 25% to 50% better data compression at the same level of video quality. H265 is the successor to the widely used H.264. Bit rates savings of 50% or more compared to MPEG-2 Through this compression, you will be able to maintain the same video quality despite using only half of the storage space. H264 standard will compress your video file to up 50% size of MPEG-2. Select between H264 and H265 depending on your file size requirement. Click File Options and click the down arrow beside Video Compressor under MP4 Encoding Settings.You may also click ALT+A on your keyboard or drag and drop a file or folder into the File bin. Click Add File button on the Home tab toolbar to add a video.
