Force Trim - Fixed Length Video

If you configured the trim tool to restrict the duration of the video by setting a minimum and/or maximum duration you can define the startup behavior of the VideoEditViewController as follows:

  • the composition or trim tool will always automatically be presented after opening for the user to review and adjust the length of the video. This corresponds to setting forceTrimMode to .always and is the default behavior.
  • forceTrimMode is set to .ifNeeded as in our exmaple and will only present
    • the composition tool, if your initial composition is longer than maximumDuration or shorter than minimumDuration, or
    • the trim tool, if your initial video is longer than maximumDuration.
  • Setting forceTrimMode to .silent will automatically trim the video to the maximumDuration without opening any tool.
