SeparateFields — VapourSynth R72 documentation

# SeparateFields

std.SeparateFields(vnode 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.
