Alight Motion Transitions: Five Repeatable Recipes
Alight Motion transitions connect an outgoing layer to an incoming layer by changing one or more properties around a cut. Build the outgoing state, the state at the cut and the incoming state; then use easing to control how quickly the values travel between them. Smoothness comes from continuity, not from stacking the most effects.
What is a transition in Alight Motion?
A transition is a timed relationship between two shots or visual states. It can use position, scale, rotation, opacity, a mask or an effect, but the effect alone is not the transition.
| Term | Meaning | Practical test |
|---|---|---|
| Transition | Change that carries attention from shot A to shot B | Inspect both sides of the cut |
| Effect | Processor applied to a layer or group | Remove it and see whether the base movement remains |
| Preset | Saved values or construction for reuse | Importing it still requires compatible layers and timing |
| Hard cut | Shot A ends and shot B begins without an animated bridge | No overlap or paired state change is required |
Think in three states: outgoing, cut and incoming. The last movement in A should establish what B continues or resolves. A technically valid pair of keyframes can still feel wrong when direction, speed, scale or subject placement changes abruptly at the cut.
Prepare a controlled transition test
Use two short clips or photos with a clear subject. Match their canvas, orientation and visible coverage before adding movement. Work on a duplicate project so failed experiments do not damage the main edit.
- Put the outgoing layer above or before the incoming layer.
- Create an overlap long enough to inspect both layers where the transition occurs.
- Mark the intended cut inside that overlap.
- Choose one primary property: opacity, position, scale, rotation or mask progress.
- Set the outgoing layer’s start and cut states.
- Set the incoming layer’s cut and end states.
- Apply easing only after the correct endpoints are visible.
- Preview from before the first keyframe to after the last one.
- Export the same short interval and compare it with preview.
Change one variable per pass. If scale, blur, shake and easing all change together, the result cannot reveal which choice fixed or damaged the cut.
Five Alight Motion transition recipes
These recipes define state relationships rather than universal numbers. Clip length, frame rate, movement and subject framing determine the final values.
1. Crossfade
Overlap the two layers. Keep the outgoing layer visible at the start of the interval and reduce its opacity toward the cut or end. Raise the incoming layer from transparent to visible across the same interval, or place it underneath and fade only the upper layer.
Use a crossfade when the shots differ in movement or composition and a spatial move would expose that mismatch. Watch for a brightness dip at the midpoint: two partially transparent layers do not always preserve the apparent luminance of either source.
2. Slide
Move the outgoing layer toward one edge while the incoming layer enters from the opposite side. Both motions should agree about direction and timing at the cut. A rightward outgoing move paired with an unexplained leftward incoming move can read as a reversal rather than one continuous push.
3. Zoom
Animate the outgoing layer’s scale toward the cut and start the incoming layer from a related scale before it settles. Align the perceived center with the subject, not merely the geometric center of the canvas. A subject that jumps location while the frame zooms breaks the illusion.
4. Shake impact
Create a controlled burst around the cut rather than constant random motion. The movement should rise from a readable base state, peak close to the impact and return toward stability on the incoming side.
5. Wipe or dissolve
A wipe reveals the incoming image through a moving boundary. Animate a mask or a documented wipe-style effect from unrevealed to revealed while both layers overlap. Keep the edge direction consistent with movement inside the shots when possible.
Choose the transition from the cut
Do not choose a recipe only because it is popular. Read the two shots first and select the smallest bridge that preserves their relationship.
| Cut condition | Strong starting choice | Reason |
|---|---|---|
| Similar framing with a time or mood change | Crossfade | Preserves composition without inventing camera travel |
| Subjects or camera already move sideways | Slide | Extends an existing direction across the cut |
| The focal subject stays in a related position | Zoom | Carries attention through a shared center |
| A beat or collision needs emphasis | Shake impact | Concentrates displacement around one event |
| A foreground object can cover the frame | Wipe | Hides the cut behind a moving boundary |
| Shots have no useful visual continuity | Hard cut | Avoids decorative motion that exposes the mismatch |
Audio can supply the event that the picture resolves. Place the visual peak on the intended beat or impact, but judge the frames on both sides as well. Moving every keyframe onto the beat can collapse the acceleration and recovery into one instant. Keep the cut, fastest change and settled endpoint as separate decisions unless the intended style calls for an abrupt snap.
When a recipe fails, return to the hard cut and add one relationship at a time. This establishes whether opacity, spatial motion or an optional processor earns its place.
How do you make transitions smooth?
First make the endpoints correct; then shape the speed. Linear movement holds constant value change and can look mechanical. Ease-out suits an object entering and slowing toward its destination. Ease-in-out suits movement that starts, accelerates and settles between positions.
Avoid treating one curve as a universal “smooth graph.” Choose the curve from the motion’s job:
- entering and settling: emphasize deceleration near the end;
- leaving the frame: allow acceleration away from the start;
- passing through the cut: preserve speed and direction across both layers;
- impact: concentrate the fastest change near the beat, then recover.
Run a continuity audit at the cut
Pause one frame before, on and one frame after the cut. Compare the following:
| Attribute | Question |
|---|---|
| Direction | Does movement continue or intentionally reverse? |
| Speed | Does visual velocity jump without an intended impact? |
| Scale center | Does attention remain on the same subject area? |
| Edge coverage | Does any empty border enter the canvas? |
| Brightness/color | Does the midpoint flash or dip? |
| Blur | Does blur peak during motion and resolve afterward? |
| Subject placement | Does the subject jump across the frame? |
Checking the timing can fix a rough transition faster than adding another effect. For effect selection, properties and stack order, use the Alight Motion effects guide.
Why is the transition choppy or broken?
| Symptom | Likely stage | First controlled test |
|---|---|---|
| Movement feels stiff | Easing or endpoints | Confirm the start/cut/end states, then compare linear with one suitable curve |
| Jump at the cut | Continuity | Compare position, scale center and velocity on three adjacent frames |
| Black or empty edge appears | Layer bounds | Disable blur/shake, inspect coverage, then restore one processor at a time |
| Crossfade becomes too dark | Opacity relationship | Compare a single upper-layer fade against paired opacity animation |
| Shake hides the subject | Amplitude/frequency | Reduce magnitude and make the burst return toward zero |
| Preview stutters | Render load | Disable heavy blur, distortion and repeated layers individually |
| Export differs from preview | Render/output | Export the isolated interval at the project frame rate and compare exact frames |
| Imported recipe looks wrong | Dependency mismatch | Check layer type, aspect ratio, fonts, media, effect availability and timing |
How do you check a transition before reusing it?
Preview the cut one frame before, at, and after the transition, then export a short sample. Keep the project frame rate, overlap length, keyframes, easing curve and effects with the saved transition so you can reproduce the result in another edit.
Frequently asked questions
How do you add transitions in Alight Motion?
Overlap two layers around the cut, choose one main property, set outgoing and incoming states with keyframes, then apply easing that matches the movement. Preview before and after the cut, inspect edge coverage, and export the isolated interval for comparison.
How do you make Alight Motion transitions smooth?
Match direction, speed, scale center and subject placement across the cut before adding blur or shake. Set correct endpoints first, then use a curve suited to entering, leaving or continuous motion. Check one frame before, on and after the cut.
What is the easiest Alight Motion transition?
A crossfade is usually the simplest because it depends mainly on overlap and opacity. Place one layer above the other, align the overlap with the fade duration, and verify that the midpoint does not create an unwanted brightness dip or flash.
Why does an Alight Motion transition look choppy?
Common causes are linear or mismatched easing, keyframes placed too close together, a jump in position or scale center, exposed layer edges, or preview load. Isolate one cause, replay the same interval, then compare a short exported sample.
Can transitions work between photos in Alight Motion?
Yes. Photos can use the same opacity, position, scale, rotation, mask and effect relationships as video layers. Ensure each image covers the canvas throughout the move, and keep the focal subject aligned so the cut does not create a visual jump.
