menu in the Video inspector that you can use to turn interlacing on
or off for the transcoded file. For more information, see the topic

About reverse telecine
Telecine is the process of converting motion picture film to the
NTSC video format used in broadcast television. The most
common telecine approach to converting film’s standard 24 fps
frame rate to NTSC video’s 29.97 fps frame rate is to perform a
3:2 pulldown (also known as a 2:3:2:3 pulldown). If you alternate
recording two fields of one film frame and then three fields of the
next, the 24 frames in 1 second of film end up filling the 30 frames
in 1 second of video.
