Added transition – now event is out of sync – Why?
Using Vegas 10d – 64 bit. I added a transition (Dissolve/Fade Through Black) between two events that were bumped up against each other in the time line (no overlap). I added it by dragging it to the timeline, in between the two events. I think I have done this in the past without experiencing what happened this time: the video and audio for the 2nd event go out of sync.
The two screen shots below show the time line before and after adding the transition. It only goes out of sync by a little — probably by the duration of the fade-through black dissolve. But the numbers that are shown in red, which I thought represent the amount by which they are out-of-sync, are + and – 1:20;17 which is actually the length of the entire event.
As I said, I “think” I have used this transition in the past without this sync issue occurring. But maybe I am remembering wrong and this behavior is normal?? I have toggled Auto-Ripple and Ignore Event Grouping to see if they could cause this, and they don’t (the video and audio of the event ARE grouped).
Anyone know what would cause this sync problem to occur when adding a transition? And why would the red numbers show +/- the “length of the event” rather than the amount by which the audio and video are out of sync? Thanks.

You moved the video to create the transition but did not move the audio. My guess is “Ignore Event Grouping” is turned on.

Thanks, Edward, but “Ignore Event Grouping” was toggled off (and the audio and video for that event are grouped together). All I did was drag the transition to the boundary between the two events. That caused the video portion of the event to “appear” to slide to the left — at least it looks that way based the video’s left event boundary location and its relation to left boundary of the audio, and to the cursor and timeline scale. This can be seen in the screen shots in my OP.
But the audio and video for that event both end at the exact same point in the timeline – their right boundaries align perfectly – even when zoomed in to get a close look. If the video had actually shifted left, then I would think the right edge of the video event would end before the audio ends. Further, when I play the event, it seems to be in-sync — there is a on-stage speaker and the lip sync seems right on.
I’m thinking that is not actually going out of sync, but for some reason Vegas thinks it is and turns the event pink. And it also thinks it is out of sync by the entire duration of the event (the number shown in red is the length of the event). Consistent with that is the fact that if I right click and choose Syncronize/By Moving, Vegas moves the entire video portion of the clip to the right in an amount equal to the duration of the event – so the video portion now starts right after the audio portion ends. So Vegas clearly thinks the out of sync amount is equal to the duration of the event.
I just tried the same thing in Vegas Movie Studio HD Platinum 10 and got the same results. It makes me think I have some setting wrong in both programs. I also tried it with different clips just in case the clip from the original attempt is corrupted. Same result with the different clips. I also tried a different transition and got the same problem.
UPDATE: Something may be wrong with my Vegas installation. To see if using Excalibur to apply transitions would result in the same sync issue, I just tried using to add transitions and it won’t add them at all. It does nothing when I click on the Apply Transitions button (after first selecting both events then adding a transition to the list with Excalibur’s “Add” button, which puts the transition name in the big white box in the Excalibur dialog, and check-marking fade in and fade out.

In my last reply I said Excalibur wouldn’t add transitions. I just want to add that I figured out that Excalibur’s “Apply Transitions” tool only works if fades have already been added to the events. After adding fades (using Excalibur) then applying transitions (using Excalibur,) the transitions are applied and NO sync problem occurs.
However, if I add fades to the events, (manually or with Excalibur(, then drag the transition to the timeline (i.e. not use Excalibur to add the transition), the sync error occurs. So dragging a transition to the timeline apparently operates in a different manner than what Excalibur does.
Guess I’ll just use Excalibur when I want to use transitions.
Still, I would like to understand why dragging the transition to the timeline causes the sync error.

I verified the behavior you demonstrated. I never noticed it because that’s not the way I apply transitions. I overlap the events exactly where I want the transition to take place, then drag the transition FX to the overlap area. Works perfectly.

Thanks, Steve. I just tried your technique. As you stated, Vegas doesn’t flag a sync problem when doing it that way. So I can use your technique in the future, or use Excalibur.
I’m glad to hear that you could reproduce the sync issue when doing it the way I had been. Thanks for taking the time to try it. That lets me know that this is normal behavior for Vegas and it was a case me not doing it right. That means I don’t have something messed up in my Vegas installation, so I am happy.
