Adding Compression or Podcast Markers to a Clip

To manually add a compression or podcast marker to a clip, you first add a chapter marker
(as described in the previous section) and then you edit the marker.

Note: A podcast can have both chapter and podcast markers. The only difference is that
the viewer can navigate directly to a chapter marker but cannot navigate to a podcast
marker. For more information, see

Types of Markers

Choose Compression or Podcast from the Type pop-up menu.

6

Enter a name for the marker in the Name field.

For podcast markers, this name does not appear to the viewer.

Optionally, enter a URL in the URL field.

This URL applies only to podcasts. The marker’s name appears over the artwork where
the viewer can click it to open a web browser to the URL’s website.

If you want to assign an image to the chapter marker, choose one of the following from
the Image pop-up menu:

None: No image is associated with the marker.

Frame in source: By default, the frame displayed is the frame on which the marker is

placed. To use a different frame as the image, enter a different timecode value.

From File: Drag an image to the image well. You can also click Choose to open a

file-selection dialog and select a still-image file to assign to the marker.

9

Click OK to close the dialog.

The marker in the timeline changes to blue if it’s a compression marker, or red if it’s a
podcast marker. You can use the Previous Marker and Next Marker buttons to select other
markers in the timeline to edit.

You also have the option of importing a chapter marker list. These lists can use either the
QuickTime TeXML format (an XML-based format for constructing 3GPP-compliant timed
text tracks in a QuickTime movie file) or a plain text chapter list file. See

Creating Plain

Text Chapter Marker Lists

for information.
