Crossfades - Trying to "get it!" :)

asafb wrote on 7/12/2002, 6:22 PM
I'm just trying to understand a basic crossfade.

Event 1 is 10 seconds.
Event 2 is 10 seconds as well.

When I cross fade like this: Event 1 <> Event 2, what exactly does Vegas do? How does it add more seconds to event 2 if event 2 is just 10 seconds to fade it in... and when it fades in event 2 while fading out event 1, what basically happens? I hope i'm not confusing you guys and sorry about the stupid question, but I'm just curious. When Event 2 was 2 seconds and I did a crossfade of 4 seconds, it looped it kinda... The crossfades are perfect - the audio is even perfectly synched, but how the heck does Vegas do this.. please explain

(both events have audio with um)

I think you'll have to repeat your question cuz it isn't coming through clearly...

when you overlap two events in Vegas, the overlapping portion defines the parameters of the crossfade. overlap it more, and the crossfade adjusts automatically. event 1 loses opacity (100% to 0%) beginning at the first overlap point and ending at the second overlap point. event 2 gains opacity (0% to 100%) beginning at overlap point 1 and ending at overlap point 2. the result is a crossfade between the two events. same thing happens with the audio except substitute volume for opacity.

And if you use the cut-to-crossfade feature, or drop a transition on the cut, Vegas trims the events longer, just like you can do with the mouse. The default behavior is to loop the clips. If you don't want this, overlap them manually so they don't get trimmed.

What is the cut-to-crossfade feature? Can you email me a jpg file at asaf@nyc.rr.com if possible? I'm using the trim command to create the crossfade. I select event 2, then put the mouse right between the two and drag event 2 into 1 which creates the crossfade. I'm just wondering will I lose any audio/video synchronization with this?

Hi,

If you're placing you mouse right at the edit-point, you're likely drag-trimming the in-point of the second event earlier to create the crossfade. This should not change the sync, but if your audio is grouped to your video, it will have an earlier inpoint and crossfade too.

For a view that may help, there is a funny lookin icon at the far left end of the video track header... right below the Maximize icon is the Expand Track Layers icon. It looks like three blocks and a "down-triangle".

Click that icon to see the video track in A-B style... where the tracks overlap determines your crossfade duration.

HTH, MPH

Cut-to-crossfade is what happens when you click between two event and then hit NumPad /, *, or -. It is also what happens when you drag-and-drop a transition to a cut. The settings for it are in Options > Preferences > Editing.

Awesome! The cut-to-crossfade thing is bad-***! :) SonicDennis, can you tell me how to adjust the length, cuz it's kinda quick :)

Nevermind i already found out in cut-to-overlap time.
Final question - whats this Switches > Loop thing mean anyway? Can someone explain it to me... (Says loops when reaches media or something like that.......)

If you extend an event past the end of the clip, it can either hold the last frame or start over again at the beginning. "Loop" means to start over. Unchecking Loop will cause it to hold the last frame.

Chienworks: Thank you very much for that answer. What do you personally use?
Chienworks wrote on 7/13/2002, 3:10 PM
asafb: personally, i rarely ever extend a clip past it's original length. My philosophy is to start the camera early, shoot long, and then trim to what i want while editing.

Is there any way to disable this? It would be nice if it would just stop dragging when you try to extend past the end of an event. I didn't see anything in the preferences menu.

TNisbet: not that i know of. However, your mouse position will "snap" to the end of the clip to make it easy to position it there. Also, if you drag beyond the end you will see a little white triangular notch at the top of the event where the end point is.

I guess I'll just have to depend on the triange to warn me. Thanks for the tip.

I'm still learning this interface. It's different than the editor I've been using, but the audio features really make it worth the effort.
