Using some recent footage, I set out to compare the various methods available to me to bring 60p slow motion to 20% speed (equivalent to 120p, played back at 24p).
The results are shown in the following order:
0:04 - 100% speed (framed are dropped from 60p to play at 24p in real time)
0:09 - 40% speed (60p conformed to 24p)
0:21 - 20% speed (Apple Motion: "Motion-blur Blending" setting)
0:46 - 20% speed (Adobe After Effects: pixel motion)
1:12 - 20% speed (Adobe After Effects: Twixtor 5 demo)
1:38 - 20% speed (Apple Motion: "Optical Flow" setting)
