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).
After doing this, my conclusions are:
- Nothing beats real slow-motion. Rent a high-speed camera!
- If you absolutely must fake it, Motion’s “Optical Flow” is slightly better than Twixtor 5 or After Effects’ pixel motion setting.
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)
