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 a recordable CD or DVD disc,
depending on the chosen video format.
