How
Much Fits on a Disc?
Different video formats compress
video at different rates. This means that how much video you can
store on a piece of media depends on the format you choose. Most
video formats also allow you to choose different quality setting.
In the video world, quality is set by adjusting the “bit
rate”. A higher bit rate means higher quality but also larger
file sizes. A lower bit rate means lower quality but smaller file
sizes. The chart below shows approximately how much video can
fit on several popular digital media storage products.
