Add a transition

1
Open the catalogue
In the Editor layout open Toolbox & VFX from the left panel bar and select Video Transitions in the TOOLBOX list. Transitions are grouped by category (Dissolve, Slide, Push, Wipe, Zoom); click a group header to collapse or expand it. Type in Search transitions to filter the list.
2
Choose a default length
The duration picker next to the search field (it reads 0.5s by default) sets how long a newly dropped transition lasts: 0.25, 0.5, 1 or 2 seconds. You can change any transition afterwards.
3
Drag it onto a cut
Drag a transition from the list onto the join between two clips on a video track and release. A transition icon appears at the cut.

Slide
The incoming clip slides in over the outgoing one, which stays still.Push
Both clips move together, as if the new one shoves the old one off screen.Wipe
Zoom
Adjust a transition
Click the transition on the Timeline to open it in the Inspector under the Transition header.
- Type: switch to any other transition from the dropdown.
- Duration: a slider with the value in seconds next to it (0.5 s for a freshly dropped transition). The minimum is 2 frames.
- Softness (wipes and Iris only): from a hard edge to a wide feathered edge.
- Color (Dip to Color only): the colour the picture dips through.
- Audio crossfade: a switch. When it is on and both clips carry sound, their audio crossfades over the same span as the picture. Turn it off to keep the audio cut hard.
- The trash icon in the header removes the transition.
Right-click menu
Right-click a transition on the Timeline for the quick menu: Duration presets of 0.25s, 0.5s, 1s and 2s, and Replace: entries for common alternatives such as Replace: Dip to Black, Replace: Wipe Right, Replace: Push Left and Replace: Cross Zoom. You can also delete the transition from here.
Ask the agent instead
The agent adds, replaces and times transitions from a prompt, which is the fastest way to handle many cuts at once: “Add a 0.5 second cross dissolve on every cut”, “Dip to black before the last shot, one second long”, “Replace all the dissolves with a 0.25 s wipe right”. Each change lands as a Timeline changes card you can revert; see Review proposals and approve actions.Transitions apply to video tracks. For an audio-only cut, animate volume with the Gain preset or keyframes instead; see Animate clips with presets and keyframes.
