Camtasia for RealPlayer Option	Description & Use
Target Audience	Select the appropriate throughput option based on the access methods your viewers are likely to use. For best performance, select the largest bandwidth likely. For conservative performance, select the smallest likely bandwidth.
Target Bitrate Settings	Set the overall bitrate for each target audience. You can control the exact bitrate (audio and video combined) to encode the streaming media file. For example, it is common to encode to a target bitrate of 34 Kbps for the 56K modem target audience, since 34 Kbps of actual useable bandwidth is typical. To set the bitrate, click Target Bitrate Settings. The Target Bitrate Settings dialog box appears. Also see the RealPlayer documentation.
Audio Target Settings	Set the bitrate allocated to the audio stream (if any) in the streaming media file. The video stream uses leftover bandwidth, if any. For example, if you choose 56K modem as a target audience and configure the audio stream bitrate to be 16 Kbps for the 56K modem target audience, then the video stream is encoded to an 18 Kbps bitrate (assuming the overall bitrate for 56K modem is set to 34 Kbps). Increase the bandwidth for the video stream (resulting in fewer dropped video frames) increased by choosing a lower audio bitrate. To set the bitrate, click Audio Target Settings. The Target Audience Settings dialog box appears. See the Real Player documentation.
Colors	Select the color depth of the video stream. 16-bit color is essentially lossless video. The 12- and 9-bit color settings reduce the color in the video, resulting in some loss of quality such as exhibiting bands of color gradients. The 12- and 9-bit color settings can significantly reduce the bandwidth required for the video stream.
Keyframe every	Determines how often to include a keyframe in the video stream. A keyframe is a video frame that does not depend on previous frames streamed to RealPlayer. Keyframes are used to recover from lost frames, during network congestion and during seeking in the video when the user moves the seek slider in RealPlayer. Increasing the keyframe frequency results in quicker and smoother seeking. However, it increases the bandwidth needed for the video stream. To set the key frame inclusion rate, enter the amount of seconds in the Keyframe every field.
Frame Rate	Choose Automatic to use the highest frame rate of all the clips on the Timeline. If the frame rate cannot be achieved at a given target bitrate, video frames are dropped. Lower the frame rate to reduce the bandwidth needed by the video stream, but video can become choppy.
Audio Format	Select a format from the dropdown list that matches the type of audio that exists in the clip(s) on the Timeline. Use the No Audio setting to produce a video with no audio track.
Preroll	Set the amount of time, in seconds, that RealPlayer initially buffers the audio and video stream before it starts to play the video. You can artificially increase the bandwidth for the video and audio stream (resulting in fewer dropped video frames) by increasing the preroll. With too large a preroll, you lose the advantages of streaming, since so much of the file must be downloaded and buffered before the video starts to play. To set the preroll, enter the amount of seconds in the Preroll field.
Details	Displays details about the audio and video selections.
