Option	Description
File type	Select Single rate for web delivery using a Web server. Select SureStream to allow streaming the video to the target audiences at different bit rates. The streaming server detects the connection speed of the viewer and selects the correct stream for the file.
Target audience	Select the bandwidth of your target audience. For the best performance, select the largest likely bandwidth. If you select too low of a bitrate, frames may be dropped in the final video. We recommend viewing the output to verify the results before pushing the content to a server. Streaming files are generally not editable and cannot be converted into another file format. Keep the original source content in the .avi file format.
Audio format	Select an option from the dropdown list that describes the audio content on the Timeline.
Video quality	Select an option from the dropdown list that describes the video content on the Timeline.
2-pass encoding	Attempts to achieve better compression by analyzing the video prior to encoding. This results in a longer encoding process, but may produce a smaller file size.
Variable bit rate (VBR) encoding	Attempts to achieve better compression by varying the bit rate for encoding different portions of the video.
