Sync video files to your Zune device

The Zune software syncs video from your library to your Zune device. To optimize the quality level or to format the file for playback on the device, the Zune software may convert the video file during the sync process depending on the format of the source file. Although you cannot turn off the conversion process for video files, you can influence the quality level of the conversion.

To adjust the quality level for converted files, follow these steps:

1.	Start the Zune software.
2.	Click Settings, click device, and then click Conversion Settings.
3.	Under Video, select Optimize videos for my Zune device or Optimize videos for TV output (takes longer).
4.	Click OK.
