How Do I Turn Video Motion Trails Into Dust?

In BeamTracer Performer, add TIME CUBE and use FRAME STACK with a STRAIGHT timeline. Set BACKGROUND → PERSON and raise DISSOLVE to make the oldest poses break into drifting dust while the current pose stays whole. Add STAGE → FLOOR to give the trail a pool of light and cast shadows beneath it.

How do I keep the current pose clear and dissolve only the echoes?

Start with one person moving across the frame. Use RECENT HISTORY and BACKGROUND → PERSON to keep that person in each copy, then let the clip play long enough to fill the stack. A held pose will look like a row of duplicates.

At DISSOLVE: 0.8, the last few copies break apart first. The picture remains visible on the echoes that have not crumbled.

Reduce DISSOLVE if the copies disappear before you can read their poses. Turn up CRUMBLE for larger pieces, or reduce GRAIN SIZE to make the dust finer. If the DUST controls are missing, check that the view is a straight frame stack and that DISSOLVE is above zero.

How do I put the dust trail under a spotlight?

Load LOOKS → DUST TRAIL to start with a long trail, or AFTERIMAGE ROW for five poses with more space between them. In TIME CUBE, raise STAGE → FLOOR to reveal the surface. Increase SPOTLIGHT SIZE if the last poses fall outside the pool of light. Use LIGHT DIRECTION to angle the light; the shadows turn the other way. Set their strength with SHADOWS.

AFTERIMAGE ROW holds the echo colors steady. The smaller number of copies makes it easier to see the space and shadows between poses.

Choose ECHO COLOR → MATCH DUST for flat silhouettes with the same colors as the dust. PICTURE keeps the original clothes and skin tones on the echoes. If the dust obscures the current pose, change WIND DIRECTION to send it across the back of the picture, then adjust LIFE to decide how long it hangs there.

Can I make the dust burst on the beat?

Raise BEAT BURST for a stronger dissolve on detected beats. Press HIT in TIME CUBE to test a single burst without music. Set BEAT BURST back to zero when you want the trail to erode steadily. The examples here are silent; use your own track to check where the bursts land before exporting.

Time Cube places earlier pictures in order behind the current one. The floor and orbit help you see their spacing; they do not reconstruct the dancer as a 3D model. The Time Cube basics cover scrubbing and onion skins, and the effect guide lists the dust controls. Check pricing for current export access.
