Split Node

The Split node enables you to separate a series of video frames into alternating " field frames." For example, a video clip of one second duration comprises 30 frames. The Split node will split such a video clip into a 60-frame sequence that alternates even and odd fields as separate frames. Therefore, the Split node accepts one input and outputs twice as many frames as in the input sequence.

Use the complementary Merge Node to recombine the field frames.

Note:
To deinterlace frames and keep only the odd or even field information in each frame, without creating additional frames, use the Deinterlace Node instead of Split.

Split Parameter Tab

Field Order

This parameter specifies whether the alternating field frames generated by the Split node should begin with the odd field (lines 1, 3, 5, etc.) or even field (lines 2, 4, 6, etc.).

Even, Odd

Begin with an even field, and use the odd field in the following frame.

Odd, Even

Begin with an odd field, and use the even field in the following frame.

Other Field

This parameter enables you to specify how to treat the vacant spaces that remain once the Split node separates the odd or even lines into separate field frames. Use the popup menu to select one of the four available options:

Use Black

This option fills the vacant lines with black.

Copy from Previous

This option fills the vacant lines with data replicated from each previous line.

Average Above and Below

This option fills the vacant lines with data obtained by averaging the preceding and subsequent lines together.

Throw Away

This option discards the data that formerly occupied the now-vacant lines. The Throw Away option has the effect of shrinking your file by 50% in the Y dimension. (In other words, a file that was originally 720 x 486 will become 720 x 243.)
