Scene Detection

160

UM-2014.1-07

The Scene Detect module can perform an automatic detection of scene

Setup

To configure scene detection, switch to the

Scene Detect

tab.

Parameters

scene changes. The lower the value the less sensitive scene detection

is going to be, so changes have to be very obvious to trigger a scene

change, whilst the higher the value the more sensitive to changes the

scene detector is going to be and smaller amounts of changes will

trigger an edit. If this value is too high then edits will be inserted in the

middle of a scene, whilst if the value is too low scene changes may be

missed.

Lead In

leave in a segment before the next edit is inserted, with the default set to

5 frames.

So at its highest sensitivity setting, the scene detector might be

detecting scene changes every frame, but it will only insert an edit every

5 frames.

Field Boundaries

If enabled, edits can also be inserted at field boundaries on interlaced

material.

When working with interlaced material scene changes sometimes

occur between fields as opposed to between frames, so by turning on
