Processing

Select which options you want to use for preprocessing content to improve the quality of the encoded content.

None. Click if you do not want to apply any preprocessing filters to your content. You should only use this option if your content is already in progressive-scan display format.
Deinterlace. Click to separate the interlaced fields of your video into individual frames, which can result in a smoother-looking video.
Inverse telecine. If your source video was telecined, click to remove the extra frames that were added during telecining. Click Auto to have the telecine pattern be detected automatically. If the telecine pattern in your content is coherent, in the list, click the setting that corresponds to the first frame in the source video.
Maintain interlacing. Click if your source video is interlaced and you want to preserve the interlacing in the encoded video.
Detect. Click if you do not know whether your content was interlaced or telecined. The encoder analyzes the content and recommends the appropriate filter to apply.
Pixel format. Select a pixel format that you want to use.
Flip vertically. Select if your video is upside-down. Upside-down video can result from using a capture device to create .avi files that do not fully conform to published specifications. Upside-down video is usually related to the pixel format the device uses.

Voice codec optimization. If you are using the Windows Media Audio 9 Voice codec, you can optimize the codec behavior by identifying if the content is voice only or if it also contains some music. Click Audio with voice emphasis if your content contains both voice and music. During encoding, the codec automatically uses the appropriate algorithm to optimize encoding for the content (voice or music). Or, you can create an optimization definition file that optimizes the audio by identifying the places in your file where music starts and ends.
5.1 audio. If you are encoding multichannel audio content, the channels are automatically folded down to two channels for playback with stereo speakers. However, you can use the settings in this area to customize the fold-down distribution. The values you specify are not absolute values. Instead, the overall gain of the channels will be normalized to avoid distortion. The values you type must be between 0 and -144 decibels. (This option is not available when you are encoding 7.1 audio.)
