This section relates to troubleshooting tracking and slide issues you may encounter with your Presto for Vegas Pro projects.
Typically, if Presto makes a tracking error, all you need to do is delete one or more of the erroneous pan-crop keyframes that were generated in the vicinity of the problem. Presto respects any manual keyframe deletions that you make. The deletions are remembered even when you make further layout changes, or simply refresh the layout. Manual adjustments to the size or position of a keyframe may not be preserved if the layout is refreshed.
NOTE: You can reduce the likelihood of tracking issues by controlling tracking with markers and regions.
To edit pan-crop keyframes, right-click on the event on the presenter track that you want to edit and select Video Event Pan/Crop... from the menu. The pan-crop view will appear, as illustrated below. In this example, you can see that the keyframe is not well centered on the presenter, so it is a candidate for manual deletion.
You will typically have many keyframes, so it helps to zoom up on the timeline using the "+" zoom button on the right-hand end of the pan-crop timeline.
To quickly navigate through the keyframes, use the arrow buttons at the lower left of the timeline.
To review slide synchronization results, you need to compare Presto's slide selection against the original projection screen video. The following technique is handy for doing this quickly:
One caveat: If your projection screen video is broken up into multiple events on the timeline, you will need to open each event in turn as you reach them on the main timeline.
If Presto selected the wrong slide, just delete the invalid slide event from the slide track and drag/drop the correct slide from the Project Media tab. Similarly, if there is a slide timing issue, just drag the slide event start/end to correct as needed. Hitting the Refresh button in the Layout Sequence tab will then make sure all the slide markers are in the right place and have the appropriate slide number.
Presto may leave gaps in the slide track for several reasons:
By default, Presto will switch to the "presenter only" layout during any gaps in the slide track.
At the end of processing, Presto warns you if any slide images could not be found in the screen video. You can check which slides are missing by going back to the Get Slides tab. Slides that were found and placed on the slide track have "used" after the filename.
Presto respects changes you make to the slide track, such as adding new images or adjusting the position or length of existing images. One exception is that Presto does not detect manual changes to slide transition effects, and therefore will replace your changes if a layout refresh occurs. If you wish to make changes to the slide track, it's a good idea to do this prior to adjusting the layout sequence or to making manual changes to transition effects.
You can drag slide images from Vegas Pro's Project Media view onto the slide track and adjust their length. When you are satisfied with your adjustments, go to Presto's Layout Sequence tab and click the Reset button if you wish to establish a new default layout sequence, or just choose Refresh to update the slide markers (if enabled), based on the contents of your revised slide track.
