Animation Exposure Sheet

Turn drawing holds into a precise animation timing sheet.

Try an example: A six-drawing motion study on twos

How it works

Enter how many timeline ticks each drawing lasts and a frame rate. Calculate drawing start times, total duration and GIF timing rounded to 10 milliseconds.

A drawing held for N ticks lasts N × 1000 / FPS milliseconds. Start and end tick positions are half-open intervals.
GIF stores centiseconds. Each drawing duration rounds independently to the nearest 10 ms; the reported GIF total may differ from ideal playback.
1–24 drawings, holds of 1–10 ticks and 1–30 FPS. No uploaded files are needed.
