Refreshing Still and QuickTime Assets

It is possible, during the course of creating your project, that you will need to update a still or QuickTime asset. DVD Studio Pro includes both an automatic and a manual asset refresh capability to make it easier to use updated versions of your still and QuickTime assets.

Important: An alert appears when updated assets have been detected, and the Encode view of the Log tab lists specific elements that use those assets. It is important to verify that each of these elements function correctly.

All still and QuickTime assets are automatically refreshed any time you bring DVD Studio Pro to the foreground on your computer. For example, if you are working in DVD Studio Pro and switch to a graphics program to update a still or QuickTime asset used in the current project, the asset refreshes as soon as you switch back to DVD Studio Pro.

Important: If the Simulator is active when assets are refreshed, you must close it and restart it for the refreshed assets to appear correctly in it.

You can also manually refresh selected assets.

To manually refresh selected assets
Do one of the following:
  • Choose File > Asset > Refresh.

  • Control-click the asset to be refreshed in the Assets tab, then choose Refresh from the shortcut menu.

Manually refreshing still and QuickTime assets is useful when you are updating them using a networked computer.

Note: You cannot refresh MPEG motion assets.

Issues with Refreshing Still Assets

When used in slideshows and as clips in tracks, still assets that have been refreshed will have no impact outside of the change you made to the still asset itself.

When used in a menu, there may be issues for you to work with. For example, if the asset is used in a menu also using overlays, you may have to readjust the button active areas to match any changes you have made to the graphic. The same is true if you have made changes to the layers of a multiple-layer PSD file.

Issues with Refreshing QuickTime Assets

Changes made to QuickTime assets, which can include video, audio, or both together, can have large impacts on any project elements that use them.

Re-encoding

Any QuickTime assets you make changes to that have already been MPEG encoded by the DVD Studio Pro integrated MPEG encoder will need to be re-encoded. If you have enabled background encoding in the Encoding pane of DVD Studio Pro Preferences, this re-encoding will start automatically.

Video Asset Length Changes

If you have changed the length of a video asset that is used in a track, there could be audio sync problems if other assets are used in the same track. For example, making the asset shorter would cause all video assets in the timeline that are placed after it to shift earlier because the V1 stream cannot have any gaps in it. The corresponding audio does not shift though, because audio streams can have gaps.

Making the QuickTime video asset longer does not change the clip in any tracks that use it. You have to manually change the clip’s duration in the tracks to use the added video.

When used as backgrounds in motion menus, you may need to adjust the menu’s duration to better fit with the asset’s new length.

Video Asset Content Changes

If you have changed the content of a video asset, you may need to adjust marker positions to match the new content or, in the case of motion menus, adjust the loop point.

Audio Asset Length Changes

If you have changed the length of an audio asset that is used in a slideshow, there are several issues that may arise.

  • If the audio is assigned to a specific slide: That slide’s length will change.
  • If the audio is assigned to the slideshow as overall audio and Fit to Audio has been selected: The slideshow’s duration will change.

In both cases, if you have shortened the audio asset it is possible that the slide and transition durations cannot be shortened enough to match the audio.

Making the QuickTime audio asset longer does not change the clip in any tracks that use it. You have to manually change the clip’s duration in the tracks to use the added audio.
