# Motion Editing

![](https://cdn.sbox.game/doc/systems/movie-maker/images/motion-editing.png)This editor mode gives you finer control over track data. Instead of keyframes, you sculpt the raw track data itself at any resolution you want.

To motion edit, you select a time range of one or more tracks, then tweak the properties that those tracks represent to manipulate track data. You can also cut / copy / paste ranges of time, or save the selection as a separate .movie file.

# Time Range Selection

A time range selection describes how much a modification affects each moment in time. It's broken up into three parts:

* **Fade In** - modifications gradually ramp up within this range
* **Peak Range** - times in this range are fully affected by modifications
* **Fade Out** - modifications ramp down within this range


![](https://cdn.sbox.game/doc/systems/movie-maker/images/time-range-selection.png)To make and update a selection:

* Click and drag in the timeline to select a time range
* Hold *Shift* and scroll to increase / decrease the fade in / out time
* Drag any of the parts of a time range to move or resize them
* Use *Ctrl+A* to select the whole movie's duration
* Press *Esc* to clear the selection

You can change the easing type of the fade in / out sections with the corresponding button in the toolbar, or pressing number keys when mousing over those sections. The shape of the top / bottom of the time selection UI shows what the current easing function looks like.

# Modifications

After selecting a time range, you can manipulate the properties of your movie's tracks. Only the selected time range will be affected, with the changes ramping up and down inside the fade in / out sections of your selection.

The selection will turn yellow to show a modification is in progress. At this point you can freely tweak the time selection, and when you're happy hit *Enter* or click the green tick to commit the change.

# Context Menu

The context menu for time selections has a ton of extra editing actions.

When pasting a time selection, you can additively layer track data over the existing animation. This is enabled by default, can can be disabled by clicking the *Additive* button in the toolbar while modifications are active.
