How do I make a slit scan?

Drop the clip in, pick a direction, tune buffer length and speed, export MP4.

Each strip of the output reads from a different moment in time. The original recipe used physical cameras and moving slits.

What does the Center slider do?

Sets where "now" sits in the frame. 0.5 puts the present in the middle and time flows outward. 0.0 puts the present on the left edge.

Why does my slit scan look static?

Slit scan needs motion. Use footage with lateral movement: someone walking sideways, a car passing, a camera pan.

Slit Scan

Slit scan reads each strip of the output from a different moment in time. Moving subjects stretch and smear; backgrounds freeze. The 2001 stargate sequence used the trick first; this is the browser version.

Tips

Horizontal mode with a centred subject moving sideways gives you the classic slit-scan stretch.
Set Center to 0.0 for a left-to-right time sweep. Useful on pan shots.
Radial mode reads as a circular time-warp. Works well on faces.
Buffer of 60–120 frames gives deeper displacement; watch memory on mobile.
