Confused: Effect Application

[rdenny]

I'm confused. When applying a transition (Effect step), It seems that the effect overlays the end of the first clip instead being applied across the original scene boundary. Some of the frames from the second clip appear through the transition, even though the second clip hasn't yet started! Furthermore, the frame timing seems to have shifted??

I know this is probably a stupid question. I did search the forum before asking. Here's what I see while applying a transition:

(1) The original timeline:



(2) After dragging the effect onto the timeline, but before releasing the mouse. This is what I expected - that is, the effect is applied symmetrically across the clip boundary:



(3) After releasing the mouse. The effect has shifted to the left, overlaying the end of the first clip. Amazingly, frames from the second clip show through the effect before the original clip boundary.



What's happening here? Am I losing some of either the first or second scene? How is the sound sync maintained?

Probably new-user confusion... Bob

This subject has been raised before but I don't know that it was satisfactorily answered.

I found the same thing when applying effects. I use mainly fade to black and crossfade. I found it easiest to consider the electronic files as strips of film. If you think of a cross fade with film strips you would have to overlay one strip over the second to get the cross fade transition. This is what VS does I think.

Same for fade to black, the film strip is overlaid over the black background on both sides of the transition.

I found it particularly annoying when applying transitions between short clips as they can almost disappear.

You can reduce the transition time or what I do when I know I will want to apply a transition is not trim the clip so fine. The short unwanted bits I leave on the clip are actually lost in the transition and not the bits I want to see.

Hope that helps.

Hmm... interesting! OK, I'll play with it some more. It's just non-intuitive.

I agree with PeterK's interpretatiation, that one strip overlaps the other, when transitioning.

So...
1) sound stays in sync with the strip, ie: it overlaps as well
2) overall project time will shorten, due to the overlapping.

When I use Fade-To-Black, I insert a *black* image between the strips, then transition on either side of the black image. This way, I have more control of how much of the actual video strip gets faded.

Regarding sound, I set the fade-in and fade-out to align with the transitions.

Hi
The frames are overlapped by the duration of the transition in order for the transition to take effect.
The total project time will reduce by the transition period.

Change the ‘Clip Display Mode’ in File Preferences to ‘Thumbnail Only’
You will now see all frames and not the File Name. This will give you a better view of the timeline.

Ahh... that makes sense! And thanks for the tip on Clip Display Mode. I like seeing the thumbnails in the timeline much better.

Great info!!! I really appreciate it.

You may know this:-

The timeline view can be stretched or contracted.
Allowing you to see more frames or less.

Your image / scale indicates about 2 second from 23 to 25sec’s

Click the buttons to the left of the timeline rule to control the view.
These controls vary depending on the version you are using.
VS 9 is much improved when navigating the timeline.

Not quite sure what you mean Trevor "Your image / scale indicates about 2 second from 23 to 25sec’s " - by expanding or contracting the timeline in UVS one thumbnail can be made to represent from 1 frame of video to 1 minute of video, or each thumbnail can represent a much longer period if you use the "Fit project to Timeline" option

The images i refer to are in rdenny's first post. they show a clip about 2 seconds long.
From 23 secs to 25 secs.

????????????????????????????????????

Actually, I thought it looked more like one second: from 23:20 (and a bit) to 24:20 (and a bit)...

Well, how much time was spanned is (in my view) irrelevent. The point was to show that, when applying the transition, the visual display showed that it bridges the scene/clip bountary, yet when releasing the mouse, it jumps over to the left and overlays the end of the first clip. Visually confusing.
