To Enable Field Rendering

In the Record Script dialog, turn on Field Rendering.
If appropriate, turn on Odd Rows First. This setting determines whether the odd rows are taken from the first or second rendering pass. (This is sometimes referred to as 2:1 or 1:2 interlacing.) Most video recording equipment expects the even row first, so Odd Rows First is turned off by default. If this setting is incorrect, a field rendered movie will jump badly and appear worse than if field rendering was not used.
Note: Field rendering is only useful when creating sequences that are to be played back on interlaced equipment (such as NTSC or PAL video). Field rendered sequences will not appear correct when played back with the Movies utility or other systems that do not refresh the interlaced fields separately.
