Runtime From Frame Count Calculator
Turn a total frame count into real-world runtime (and vice versa) at any frame rate — for reels, DCPs and delivery durations.
A reel of 129,600 frames at 24 fps runs 90 minutes. Because true 23.976/29.97 rates are 24×1000/1001 etc., a frame count that's '90 minutes' at 24 fps is actually 90 min 5.4 s at 23.976 — which is why delivery durations must always state the exact rate.
