Dialogs: Video range

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.
