Pulldowns - conversion into destination formats
Pulldowns are a method of converting a 24p source into a different destination format by adding extra frames to the source.
2:3 (normal) pulldown
This method is used to convert a 24p source (lm) into a 60i destination (NTSC video) by adding two extra elds for every four frames,
effectively increasing the frame rate to 30 fps. The frame is split into elds and then two elds are repeated for every four original frames as
shown in the illustration below.
