Pulldown!?
- Thread starter ggoerl
- Start date
Pulldown came from the process of taking 24fps and pulling it down to 23.976 in frame rate in order to transfer evenly with a 2:3 cadence to NTSC video. Pulldown generally refers to the additional fields created from the original 24 frames in order to make 60 fields - or more specifically; the 59.94 fields from the 23.976 frames per second of the film.
This is done by holding every other frame for an extra field creating a 2:3 pulldown cadence. In doing do, you get 12 frames of 2 fields, and 12 frames of 3 fields. 24 + 36 = 60 fields!
Panasonic introduced another form of pulldown referred to as ADVANCED pulldown. Essentially the same process but the order of the cadence is different. Instead of 2:3:2:3 frames every 10 fields, the order is 2:3:3:2. This allows for native DV editing systems to capture the 23.976fps without the need for a decompress/recompress.

NTCS video is not made up of full frames, but of fields, two per frame and 59.94 fields per second addressed by 30 frame timecode - drop or non drop. There are plenty of sites on the Internet that can give you a full description on these terms and definitions. Start with www.adamwilt.com
