Advanced Video Settings Dialog

To adjust advanced Windows Media Format video settings, click the Advanced button on the Windows Media Services Encoder Template Wizard's Compression and Formats page.

What do you want to do?

Adjust the encoded image size

Click the radio button that corresponds to the desired height and width of video encoded with the current template:

Adjust the frame rate

Enter a value from 1 to 30 in the Frames/Second box to determine the number of video frames that wll be displayed in eack second of your encoded video.

The frame rate you choose is dependent on the type of video you are encoding and your target audience:

Set the interval between I-frames (key frames)

Enter a value from 0 to 30 in the Second/I-Frame box to determine the interval between I-Frames.

I-Frames contain all information required to display an image. Frames between I-frames are called delta frames, and they contain only the information used to display change. Delta frames are considerably smaller than I-frames; however, the visual quality of delta frames is poor.

As I-frames get farther apart, the size of the video (in bytes) gets smaller, but the video quality decreases. As I-frames get closer together, the size of the video gets larger, and the video quality increases.

Choose a color depth (pixel format)

Choose a setting from the Pixel Format to specify the color depth standard for encoded video.

The video card that the computer is using to receive the video source has certain color standards that it can display best, for example, RGBH = 64 thousand colors and RGBT = 16 million colors. For information about which pixel format works best with your video card, refer to the video card’s documentation.

Set a delay buffer

Enter a value from 1 to 10 in the Delay Buffer box to determine the number seconds of encoded video that will be buffered before playback begins.

Adjust image quality

Drag the Image Quality slider to fine-tune the image quality. You can emphasize either video smoothness or image crispness: video content is smooth when movement shown on the screen has easy transition from one position to another; content is crisp when the edges of objects are clearly delineated.
