29.97fps is timecode in an interlaced video that is 59.97 individual fields ( half vertical resolution frames ) only difference to 60p is they will be full resolution frames. Very confusing I know. 60i cameras take 60 exposures just like 60p cameras they just record fields not full frames so the temporal motion is the same which is why 60i is a lot smoother than 30p because there are twice as many exposures in the same time period. The confusion is the timecode for this is 29.97fps, timecode increments every 2 fields, so people think that is close to 30P, its not.
So the 24P film frames have to be divided up into 60 fields for interlace video ( 29.97 fps timecode) with 2:3 pulldown. This will give individual frames to fields and the playback systems will know what to do to reasamble the 24p image on a suitable display on computer editing program. In other words finding the correspondding odd and even fields extracted from the full frame 24p image for inclusion in the 60i stream.
