There are only two choices for field dominance in normal interlaced video: odd or even.
Dirty frames may appear in other methods of displaying the interlaced video.

As such, interlaced video may exhibit ghosting or combing artifacts when watched on a computer.
The same or better film look effect can be achieved by converting regular interlaced video into progressive format using computer software.
This format is called interlaced video; two successive fields are called a frame.
In interlaced video each frame is composed of two halves of an image.
For explanations of why interlacing was originally used, see interlaced video.
The same or better film look effect can be achieved by shooting regular interlaced video and then converting it into pseudo-progressive format with computer software.
