Syntax
struct FMovieSceneTimeTransform
Remarks
Movie scene sequence transform class that transforms from one time-space to another.
The transform can be thought of as the top row of a 2x2 matrix, where the bottom row is the identity: | TimeScale Offset | | 0 1 | As such, traditional matrix mathematics can be applied to transform between different sequence's time-spaces.
Transforms apply time scale first, and then offset.
Variables
| Type | Name | Description | |

FFrameTime | Offset | Scalar frame offset applied after the scale |

float | TimeScale | The sequence's time scale (or play rate) |
