We have had a lot of questions on our forums about interlaced video, so I thought I would write a series of articles to clear everything up once and for all! 
Where did interlacing come from?
Back in the day, when me and my buddies were developing broadcast television, we were going to model it on film, which took a sequence of photos of reality, so, if a blue circle was moving from left to right, two consecutive frames might look like this:
Instead of the 24 frame per second …
- Shoot “advanced”- or “2:3:3:2″ mode with your camcorder.
- Use the capture preset in FCP titled “DV NTSC 48 kHz Advanced (2:3:3:2) Pulldown Removal”. This preset will capture at 29.97 (that’s what the actual recording on tape is), but remove the redundant frames added by the camcorder to make the video 23.976 fps (notice the box is checked that says “Remove Advanced Pulldown and/or Duplicate frames During Capture From FireWire Sources”)
- Use the “DV NTSC 48 kHz - 23.98″ sequence format (NOTE: FCP refers to 23.976 fps video as “23.98″)
- Now edit your masterpiece!
