Non-drop frame counting at the rounded fps integer (e.g. 23.976 fps → 24 frame slots per second). Pure browser math.
Why editors need this
Editorial timecode (HH:MM:SS:FF) is the language of NLEs, but everything around it speaks in seconds (CSV exports, captions) or in raw frames (after-effects, audio software). Converting between the three is a constant tax — this tool zeros that out.
The conversion uses non-drop frame counting at the rounded fps integer (e.g. 23.976 fps → 24 slot frames per second). That matches how NLEs display non-drop timecode on the timeline. For drop-frame projects, expect a tiny drift at long durations.
When you need to find every silent gap in a multi-hour interview, do not count frames by hand — Yond Cut Silences in the YondCut Premiere Pro plugin detects silences and razor-cuts them automatically across nested sequences.
