Open up the program and then a video project that you are hoping to tweak. The de-interlacer is very good, and the highly adjustable motionmask function works very well for most types of footage, preserving image quality and resolution where it can.

Interlacing and field order

Because of the speed of transmission, the afterglow of displays, and the persistence of vision, the viewer perceives each frame in full resolution. In most instances, a viewer is not going to notice that a video is interlaced.

With 6 cameras about 6 inches apart, you’ll span Select “Flicker Removal” from the list of options if your clip is short and without much motion.
