# SeparateFields

`std.``SeparateFields`(clip clip[, bint tff])

  Returns a clip with the fields separated and interleaved.

  The tff argument only has an effect when the field order isn’t set for a frame. Setting tff to true means top field first and false means bottom field first.

  The output clip’s frame rate is double the input clip’s frame rate. The frame durations are halved.

  The `_FieldBased` frame property is deleted. The `_Field` frame property is added.

  If no field order is specified in `_FieldBased` or tff an error will be returned.
