EDL Frame-Rate Mismatch Calculator
Spot the timing error when an EDL's timecodes are interpreted at the wrong frame rate — the silent cause of drifting conforms.
If an EDL authored at 24 fps is read as 25, every event slips progressively — at one hour in, the error is ~144 seconds. The cut still 'works' near the head, which is why these mismatches hide until late reels drift wildly out of sync. Always confirm the EDL's frame rate before conforming.
