adobe supports regular reverse 3:2 pulldown and advanced pulldown 2:3:3:2 which was the old dvx-100 method.
both take 29.97fps interlaced and turn them into 23.976fps progressive.
if you drop a 23.976 into a 29.97, it should add the pulldown automatically.
if it doesn’t, you’ll have to render out a 23.976 to 29.97 with 3:2 pulldown and import back into the timeline.

it changes the clip speed to match the sequence unless you use
