Interlaced video formats divide frames into two line-based fields. One field consists of the first and subsequent odd lines in the frame, and the other field consists of the second and subsequent even lines in the frame. During the recording process, the images that make up each field are recorded at slightly different moments. For example, when recording NTSC, field 1 is recorded 1/60th of a second before field 2.

While in Output view mode, Lustre can only display one field at a time. The field that is displayed is the active field. When you render the footage, both fields are processed.

To set the active field:

1. Toggle the F1/F2 button.
   NoteYou need to select Interlaced in the Setup > Grade menu in order to enable this button.

   This switches the view in the Player between field 1 and field 2.
