Delete Template

Click to delete the selected template. Only custom templates can be deleted.


Format

Choose a compression format from the drop-down list to specify how audio will be compressed.


Attributes

Choose a setting from the drop-down list to specify the bitrate, sample rate, and number of channels used to encode your audio.


Format

Choose a compression format from the drop-down list to specify how video will be compressed.


Frames/Second
Frame rate

Specifies the frame rate of the video stream in frames per second. The frame rate determines the speed at which individual images are displayed during playback. Higher frame rates result in smoother motion.


Second/ I-Frame
Seconds per keyframe

Enter a value to specify the interval (in seconds) between consecutive keyframes (I-frames).

Keyframes contain all the data to draw a complete video frame.


Override Default Compression Buffer

Select this check box and enter a value in the edit box if you want to specify how long a media player should buffer before starting playback.


Image size

Choose a setting from the drop-down list to specify the size of the encoded video frames, or choose Custom and enter values in the Width and Height boxes.


Width

Enter the desired width (in pixels) of each video frame.

This control is unavailable until you select Custom from the Image Size drop-down list.


Height

Enter the desired height (in pixels) of each video frame.

This control is unavailable until you select Custom from the Image Size drop-down list.


Pixel aspect ratio

Choose a setting from the drop-down list or type a value in the box to set the pixel aspect ratio of your video.

Computers display pixels as squares, or a ratio of 1.0. Televisions display pixels as rectangles (ratios other than 1.0).

Using the incorrect setting can result in distortion or stretching, Consult your capture/video output card's manual for the proper settings.


Quality

Drag the slider to adjust the quality of your encoded video.

0 is the default setting. Increasing this setting will increase the time it takes to encode your file.


Bandwidth Selection
Target bit rate

Select the appropriate check boxes to specify the target bandwidths for which you want to encode your file. You can enter a bitrate for each target to override the default.


Title

Enter the title of your encoded file. This information can be displayed by the media player during playback.


Author

Enter the author of your encoded file. This information can be displayed by the media player during playback.

When the check box is selected, the encoder can produce higher-quality video, but the encoding process takes longer.


Enable Indexing
Index file

Select this check box if you want to index your video file. When indexing is enabled, users can seek through your file using the seek bar and fast forward/rewind controls.

An index is a series of values that correspond to positions in the file.


Method

Choose a setting from the drop-down list to specify whether you want to create a time-based or frame-based index:

•	When you choose Time based, you can enter a value in the Interval box to specify the time between index entries and choose a setting from the Type drop-down list to determine the type of object that will be used to index the file.

•	When you choose Frame based, you can enter a value in the Interval box to specify the frequency of index entries.


Index Type
Type

Choose a setting to define the type of object that will be used to index your file.

Nearest video keyframe	Index entries are associated with the nearest video keyframe in the Windows Media file.
Nearest compressed sample	Index entries are associated with the nearest compressed sample in the Windows Media file.
Nearest packet	Index entries are associated with the nearest data packet in the Windows Media file.


Index Interval
Interval

Enter the interval that should be used between index entries. If you selected the Temporal radio button, enter the interval in milliseconds. If you selected the Frame-based radio button, enter the interval in frames.
