Smooth Transitions in Toji Motion: Between Any Two Clips
A transition is a promise that the next shot belongs with the last. This guide builds the three workhorse transitions in Toji Motion, times them against the music, and keeps them smooth instead of showy.

A Transition Is a Small Story
Every transition answers a question the cut alone cannot: are we moving forward in time, changing place, or changing mood? In Toji Motion for Android editors the toolbox is the same one the rest of the app runs on: keyframes, masks, shapes and effects, aimed at the seam between two clips. A transition chosen for its meaning survives; one chosen to show off dates in a month.
Keep a house style. Two or three transitions used consistently make an edit feel directed; twelve different ones make it feel restless.
The Three Workhorse Transitions
The push: the outgoing clip slides away as the incoming one follows it, one continuous movement across the seam. The mask wipe: a shape or mask edge crosses the frame and the scene changes behind it, built exactly as our masking guide describes. The zoom through: scale climbs into a detail of the first clip and out of the second, a move that lives and dies by its easing in the graph editor.
Build each once, slowly, and save the pattern. Workhorse transitions are capital: made well a single time, they pay out on every edit after.
Timing and Easing
Most transitions want to live between a third of a second and a full second. Shorter reads as a cut with manners; longer becomes a scene of its own. The easing carries the realism: movement should accelerate out of the first clip and settle into the second, never glide at one flat speed, because nothing in the physical world moves that way.
The shake effect is the punctuation mark of this family, a two or three frame impact that makes a hard transition feel like a landing. Use it where the music lands, not where you ran out of ideas.
Matching Cuts to Music
A transition that lands on the beat needs no defence; the audience feels it as rightness. Place the seam's midpoint on the hit, not its start, so the movement crests exactly with the sound. The beat-finding method is the one in our audio sync guide: waveform first, pictures second.
When music is absent, cut on movement instead: mid-pan, mid-gesture, mid-turn. Motion hides seams the way rhythm hides them in songs.

Quick Answers
How long should a transition be?
Most work best between a third of a second and one second. Shorter feels like a polite cut; longer becomes a scene of its own and should be used sparingly.
What is the easiest transition to learn first?
The push. Two clips, one continuous slide across the seam. It teaches timing and easing, and it suits almost any pair of shots.
Why do my transitions feel jarring even when they are smooth?
Usually the timing against the sound. Land the middle of the transition on the beat, and ease the movement so it accelerates and settles rather than gliding flat.
