This dialog allows you to configure scene length.
You can change the length of the scene.
If you set the scene length longer than the number of data sequence, frames beyond the sequential data shows the last data.
You can set work area in unit of sub step. Use this feature when you wants to re-render several substeps, for example.
Time remap is currently not implemented.
Work area is the range at which animation will be played.
Work area defined by substeps is shown by red slider in timeline.
This option determines whether the keyframes in Timeline Editor would be remapped when the scene length is changed.
