What is the best way to add a push transition (right to left), so that all clips in the left are pushed left by the clip in the right?

I currently duplicate the right clip in every track, adding the transition to every track.

I'd tried compound clips and adjustment clips, but it seems it's not possible to add transition to them.

Is there an easier way to do this?

Compound would do it, but you'd need to account for the necessary handles.

Could you please elaborate?

I can't find a way to add transitions to a compound clip.

The main purpose of it in my case would be transforming 20 regular clips in one single compound clip, so that adding a transition would be a much simpleer operation, once the compound clip is just 1 clip instead of 20.

But I just don't know how can I add a transition to a compound clip. It seems to be impossible.

Make sure you have sufficient handles on the compound clip and the clip you are transitioning to.

You don't need to use compound clips.

1. Select the multiple edit points

There are a few ways to do this. The simplest is to directly click them in on the timeline, holding shift to add more. But you can also use "selection follows playhead," in combination with keyboard shortcuts if you don't want to use the mouse. V selects nearest edit. Once the playhead is targeting edits instead of clips, walking up and down the timeline with the up/down arrow keys will select multiple ones wherever they intersect the playhead, and track auto-targets are enabled.

2. Press Cmd/Ctrl-T to apply default transition.

3. Change the transition type to "Push"

If the default transition isn't already set to "Push," you can change it under the "Transition Type" menu in the inspector after the fact, or you can right-click on it in the effects library, and select "Set as standard transition" from the dropdown before the fact.

Since Push Left is the default behavior, you'd then shift-click all of the transitions, and change their behavior in the inspector to "Push Right" simultaneously. If you know you're going to need to do this bazillions of more times, you can right-click on one of the altered transitions in the timeline, once you have it set the way you like it, and choose "create transition preset" from the dropdown. After you do, there will be a new "user" category of transitions in the effects library, and you can make this one your default.


In your screenshot, you've got three outgoing clips and only one incoming clip. I can't tell from the picture if you've got them composited somehow, or if you have a tiled arrangement. If it's the latter, I'd suggest using the new Video Collage effect, which handles the animation. All you need to do in that case is set it up on one of the clips (the topmost in the stack for simplicity's sake), copy, and paste attributes to the other clips, then change the active tile assignment of the second and third layers to 2 and 3, respectively.

If that's not what you're doing, and they need to stay visually aligned on top of one another, just remember you can walk through the edit types (in/out/both) with the "U" key.
