44 Chapter 4 Managing Your Media With QTSS Publisher

Improving the Performance of Hinted Movies Exported From

QuickTime Player

When you export a hinted movie from QuickTime Player, you can compress video and

sound using either the native RTP payload encoder or the generic QuickTime payload

encoder. Generally, native payload encoding is preferred. Check with your codec

manufacturer for specific guidelines regarding payload encoding. Use care and

experimentation when choosing between native and QuickTime payload encoders.

To change the encoding used when you export from QuickTime Player:

1 Choose File > Export.

2 Choose “Movie to Hinted Movie” from the Export pop-up menu.

3 Click Options and then click Track Hinter Settings.

4 Choose an option from the RTP Payload Encoding pop-up menu.

To maximize the number of connected users—rather than saving disk space—select

the “Optimize hints for server” checkbox. (In most cases, you’ll want to leave the

checkbox deselected.)

Choosing a Thumbnail for a Movie on a Webpage

When you use QTSS Publisher to embed a streaming movie in a webpage, you can

choose a custom image to display until the movie starts playing. If you don’t choose a

custom image, the movie’s poster frame (the first image or the frame selected in

QuickTime) is displayed.

To select a still image to represent an embedded movie:

1 In QTSS Publisher, click Library or the playlist and then select the movie.

2 If you have an individual file you want to use as the poster frame, select Custom Image,

click Choose, and select the file. Or drag the file from the Finder to the Thumbnail

Image well in QTSS Publisher.

3 Click Apply.

If you don’t have a separate file, select the movie in the Finder (use Column view), play

the movie in the Preview column, click Pause when the desired frame appears, and

drag from the Preview window to the Thumbnail Image well.
