Syncing Audio when using Crossfade Effects

[jimswinder]

Using two cameras but only using audio from one camera.
I have split the audio from the one camera as the Master Audio track.
When editing and cutting back and forth between cameras (putting a Crossfade effect between each cut) how do you keep the audio in sync since it shortens the overall length of the video compared to the original length of the audio?
Using Video Studio 2018.

Put one camera on main, the other on overlay track.

I have done that...but when inserting a Dissolve Effect it shortens the video shorter than the audio track. This is not a "live" edit, it is footage from two cameras.

The two videos are in sync?
You trim/cut only the overlay muted track , and apply trans to it. it will not move

Have you tried using Multi Camera Editor

Oh... why do you need to split audio?
If you are cutting the video and removing sections then I assume the remaining video contains the audio you need, so why split audio.

[jimswinder]

I split the audio because when I go back and forth between the two cameras I am cutting out the footage with the good audio when using the footage with the bad audio.

Ah, I understand. I worked around the issue but you probably will not like the procedure. The Ripple Editing function will not work in this case (perhaps a bug?).

I found two methods as work arounds, both are tedious if there are many A>B transitions as each transition requires manual adjustments.

The first method involves splitting and manually moving the tail split audio with auto fade in/out enabled. The biggest issues are you MUST have your project storyboard and timeline layed down first, no changes can be made later with a lot of pain. This procedure is linear and repetative so it takes a lot of time.

Procedure #1
Lay down the video clips in order on the Video timeline.
Lay down the single audio track on the Music1 timeline.
Set cursor to the first transition point, select (click on) the audio track then CUT the track.
Repeat for each transition point along the timeline that are associated with the soundtrack.

Return to te first transition cut.
Select on the right segment of the audio track and just slide it to the right a short amount to create a gap (temporarily parking the clip).
Select the desired transition and drop it on the first transition point. Adjust as desired.
Select the audio segment youparked and move it to the left until it either snaps to the beginning of the video transition or move it left then grab the right end and snap it to the end of the video clip.

Move to the second transition point and repeat the procedure above until you reach the end of the timeline associated with the audio clip.

You can see this is not a fun task for a large project (small ones aren't difficult).

The second method I tried are also involved but not a "tricky" with snapping segments together. Instead, I create two freeze frames at each transition point (one frame per side of the point). The frame time length is equal to the transition time length. Insert the two images at the transition then apply the transition.

This method leaves the audio track intact and Ipso Facto the original time length. However, it substancially changes the the nature of the transition - it no longer has video motion (as the transition segments are freeze frames), only the transition effect. This second method actually goes quite quickly.

Jim, you missed the point of overlay tracks.
Any video in it will cover the main track, so no need to cut it away.
Here a gig I edit few months ago. not with VS, but with VMS.
Here the main track is below the overlayes

Another idea! How about this -

As long as you use the same type of transition, one that CROSSES (which means not the Fade to Black), then make each of your video segments LONGER by the total amount of transiton time. Thus a clip with a head and tail transition on three seconds per transition needs to be "X"+6 seconds.

This waythe transition time is accounted for and the audio will remain in sync.

Thanks asik1...I will give that a try.

Maybe I missed something but I would have thought MCE would do what you want.
Although adding transitions is possible, not sure about their duration.
