1. Open the Encoder Presets window.
2. Select a Flash 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 VP6 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 is a target value
for the encoder and 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. Check Key Frame (optionally) and enter the number of frames. A movie is a
sequence of images and each image is called a frame. To compress video data,
most encoders take a frame and make it a reference (also known as a key). This
keyframe is sent as part of the broadcast, and all of the data after that keyframe is
relative to it. The benefit of this is that the compressor only needs to send what has
changed since the last keyframe. The main drawback of this is that over time it
