SeparateFields

std.SeparateFields(clip clip[, bint tff, bint modify_duration=True])

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.

If modify_duration is set then the output clip’s frame rate is double that of the input clip. The frame durations will also be 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.
