Selects a subset of the input to use.

Input range
  Controls how much video at the beginning and ends of the source is skipped during processing, so that only a portion in the middle is used. All offsets can be set in either frames or milliseconds (ms).

  Note | Offsets persist even if you load a new file.

  Note | The end offset is the number of milliseconds from the end, not from the beginning. It is usually easier to set start/end points from the position control (HOME/END).

  Note | You can only select a single range with this dialog; use the delete frames feature to extract multiple segments in a single pass.

Offset audio to maintain a/v sync
  Controls whether the start offset applies to the audio stream. If unchecked, the start offset deletes frames only from the video stream, advancing it that many frames ahead of the audio stream. This will alter audio/video synchronization accordingly.
Cut off audio when video stream ends
  If the audio stream is longer than the video stream, this controls whether the extra audio is used or not. Generally, players continue to show the last video frame while the remaining audio plays.
