Flash H.264
To modify a Flash H.264 preset, follow these steps:
1. Open the Encoder Presets window.
2. Select a Flash encoder preset from the Encoder Presets menu.
Note: To use a newly created preset (See Creating New Presets).
3. Check the Video Encoding checkbox. When checked, the video for your broadcast
is encoded. When unchecked, a blank video screen is provided. This is the preferred
method of producing audio-only broadcasts.
4. Select the H.264 encoder from the Encoder menu.
5. Enter the width of your broadcast video.
6. Enter the height of your broadcast video.
7. Select the desired frames per second (FPS) of your broadcast. This value is a target
value for the encoder and the exact value is not guaranteed.
8. Enter the average bit rate in Kbits (1000 bits) per second. This is the target bit rate of
your video. Higher numbers provide better quality. The connection speed of your
audience is a significant factor in determining your target bit rate. The encoder
compresses the video to approximate this target. However, at different times
during your broadcast the bit rate may be higher lower than the target rate.
9. Select an encoder profile from the Profile menu. Two profiles are provided: Baseline
and Main. The Baseline profile is commonly used in mobile applications. It is also
used in other applications which operate with limited processing power, storage
