Hints for Minimizing Bitrates

Audio Notes

To minimize wasted audio ovehead and minimize audio bitrates, you should set one of the following:

1. Set the Audio Bitrate to 56 Kbps and the Sample Rate to 48 KHz. Encoding MUST be AAC (results in 63 Kbps); or
2. Set the Audio Bitrate to 64 Kbps and the Sample Rate to 32 KHz. Any audio encoding (results in 84 Kbps)

At low bitrates, we have found that MPEG1/Layer2 Audio Encoding sounds best.
(Note: setting MPEG1/Layer2 to 56 Kbps results in a total of 126 Kbps audio overhead.)

Low-Bitrate Encoder Settings

On the Encoder menu:

1. Click on "Default" to reset the Encoder Profile.
2. Then set the following:
