# Tesseract controls speed ramps with an editable time curve

By Steven Van · 2026-10-05

Adjust acceleration and slowdowns in a shot while keeping source audio separate from visual timing.

A shot can move from fast action into a slower moment and accelerate again using Tesseract's editable time-remap curve.

## Refine the timing

The curve controls which source frame appears at each point. Agents can move the slowdown around a particular moment, adjust acceleration and refine the curve without rebuilding the shot.

Mirage’s [October 5 announcement](<https://x.com/trymirage/status/2107147594883338727>) also confirms optical flow and frame blending, with acceleration, slowdown and held frames remaining editable.

## Handle audio separately

Keep dialogue and music on separate audio layers while refining visual timing. Nonlinear visual remapping does not automatically provide matching, pitch-preserved audio. Tesseract previews and renders locally on macOS, Windows and Linux; agent costs are separate.

See the [official speed-ramp guide](<https://mirage.app/tesseract/features/speed-ramps>) for the editable workflow.
