Since the duration of the pag file is fixed, the duration of the pag file needs to be changed dynamically in some scenarios. For example, in the case when the placeholder image fills the video, the length of the video varies, and the pag file needs to be dynamically stretched to match.
When the play duration of the PAG is inconsistent with the duration of the pag file, time stretching will be applied.
Time Stretch Settings
- none: no stretch
- scale: linear stretch
- repeat: repeat
- repeatinverted: Repeat in reverse order (played in reverse order after the end)
- Valid when the mode is scale. A pag file can only have one stretch interval.
