Then enter the film's image dimensions and frame rate in the lower part of the calculator. To do this, do the same as above to calculate the actual video bitrate and write down or memorise this number. Or likewise, if you want to avoid wasting download time on a file that is just too small to possibly offer good quality. You can use this to either represent multiple tracks (for instance languages), or multiple discrete surround channels.Īnother useful scenario is to determine whether a video file can fit in a fixed-size medium like a DVD-R at acceptable quality. Total audio bitrate is the number of audio tracks times the given audio bitrate. To do this, enter the duration, audio bitrate and target size, and press the “Video from time,size,audio” button.
The classic use case is to determine the required video bitrate to fill a fixed-size medium like a CD-R or DVD+R, given a fixed audio bitrate and movie duration. If you prefer either or the other, or if touch UI detection should fail, the button below the calculator allows to override it. Highlighting behaviour differs between desktop and touch browsers due to differences between a cursor- or touch-driven UI. When clicking a button or having edited a field, fields updated due to this action will flash bright yellow. Fields used as inputs for a button or edit field are highlighted in green, and output fields in pale yellow. This calculator is intended to make bitrate calculations for encoding movies easier.
