Slow-Motion / Conform Speed Calculator
Shoot at a high frame rate and play back at base rate — get the slow-motion factor and the real-time duration of your clip.
Shooting 120 fps for a 24 fps timeline gives 5× slow motion: a 2-second action beat stretches to 10 seconds of smooth slow-mo. Overcranking captures more frames so playback has real motion to show — far cleaner than software frame-interpolation after the fact.
