What to try
- Choose a frame and move its dot; onion skin reveals the neighboring positions while paused.
- Duplicate a frame to hold that pose, then play at different frame rates and compare the total duration.
What to look for: Duplicating a frame adds time without a new position. Raising FPS shortens the sequence, but cannot fill a gap between two poses.
How it works
At 12 frames per second, each frame lasts about 83 milliseconds. Doubling the rate halves the total playback duration when the frame count is unchanged. Adding frames creates more opportunities for motion detail, but duplicating an unchanged frame only increases its hold time.
Onion skin displays a neighboring frame as a translucent reference while editing. It helps compare positions without becoming part of the exported frame. Each Lab frame has its own layer stack, so changes to one frame do not automatically change every other frame.
Use it in the Lab
Use the Animation dock in the Lab to add, duplicate and reorder frames. Keep the document dimensions consistent and use onion skin to maintain continuity. Export a sprite sheet or numbered PNG sequence with frame-rate metadata.
Limits & distinctions
The current editor does not export an animated GIF or video. A sprite sheet stores the images; another player or production tool must apply their timing.
