I did few quick test shots on my system last night focused on this 3:2 pulldown.
My previous posting regarding TV generating 3:2 pulldown is correct.
Original 24p test posting with information on the test principle:
24fps at 24Hz to display.
RC on, 1 to 1 exact film cadence
TM on, DJ 0 cancels RC starts 3:2(6:4) pulldown
TM on, DJ 0 DB 1 to 10 - no visible changes, still 3:2 pulldown, CONFIRMED
TM on, DJ 1 frame transition improvement, correct 24fps film cadence
TM on, DJ 1 to 10 gradual dynamic frame transition to full fluid motion 120fps
In order to get correct 24fps film cadence you need RC on or DJ 1 or greater.
If you use TM with DJ 0 and De-Blur 0, 6 or any other number you will end up with 3:2 pulldown.
This should be correct for all OLED series and all firmware versions. It is the logic behind LG motion controls.
24fps at 60Hz to display
RC is greyed out and disabled
3:2 pulldown is done by player and TV displays 60fps as they come.
TM on DJ 1 or greater will try to even out frames back to 24fps
DB effect is questionable with 24fps film material.
24p test shows 3:2 pulldown coming from the player. When DJ is 1 or greater test file shows correct even frame exposure but this is only true with this test file. The LG motion processor is performing complex algorithms to detect objects in motion and directions of movement few frames in advance. It is easier to detect pattern of squares and correct frames compared to real movie. When playing Hell or High Water opening scene from external player using 60Hz and DJ setting of 3 or 4 I can still see uneven frame advancement, somehow stuttering rather than 3:2 sequential pulldwon.
I played this opening scene few times and experiment with combinations of DJ 3, 4 and DB anything from 0 through 5, 6 all the way to 10. I couldn't see any difference at all by eye. I didn't have time to make slow motion videos but if I can't see by eye it's not that significant if anything at all. Small adjustments on DJ from 3 to 4 make a big difference but DB 0 or 10 seems like nothing at all.
Test pictures from 24p test confirming film cadence:
Display frequency is in the file name. Moire pattern is coming from camera sensor to screen pixels pattern and based on auto focus.
