What is a Timecode Calculator?
A timecode calculator converts video position between total frames, HH:MM:SS:FF, and wall-clock seconds at a chosen frame rate. Post and review teams use it to write precise notes, sync references across timelines, and translate player timestamps into editor-friendly timecode.
How to Use the Timecode Calculator
Bidirectional conversion between total frames, HH:MM:SS:FF, and total seconds — all in the browser.
Choose your FPS
Pick the project frame rate (23.976–60). The calculator labels results as NDF / simple frame math — no drop-frame skipping.
Enter frames, timecode, or seconds
Edit any field: total frames, HH:MM:SS:FF, or total seconds. The other values update immediately so you can convert seconds to timecode or the reverse.
Copy into review notes
Copy the result and paste it into editor notes, Slack, or Kreatli video review comments so everyone lands on the same frame.
After you convert a moment, open the free video reviewer to leave frame-accurate feedback with your team.
