Fitting Your Project on a DVD-5 Disc
You can use this simple formula to estimate the bit rate you should use to fit your video
on a DVD-5 disc:
560/x = bit rate
The “x” represents the length of the video (in minutes) and the resulting bit rate is in
megabits per second (Mbps). This formula assumes you are using compressed audio,
such as AC-3. If you are using uncompressed audio, you need to subtract 1.5 Mbps
(assuming you are using 16-bit stereo at a 48 kHz sample rate) from the bit rate value.
For example, if you have 120 minutes of video, you get a suggested bit rate of 4.67 Mbps
(560/120 = 4.67). If you are using uncompressed audio (such as the AIFF format the
embedded AIFF encoder supplies), you need to reduce the bit rate to 3.17 Mbps to ensure
the video and audio will fit on the disc.
