Timecode ↔ Frames Converter

Timecode is a standard way to label an exact position in a video, written HH:MM:SS:FF — hours, minutes, seconds, and frames. The frames field counts up to the frame rate before the seconds roll over.

Divide the total frame count by the frame rate to get total seconds, then break that into hours, minutes, and seconds; the remainder of frames becomes the FF field. This tool handles the math at any frame rate.

The same frame count represents a different duration at different frame rates. 900 frames is 30 seconds at 30fps but only 15 seconds at 60fps, so the converter always asks for an fps value.

This converter uses non-drop-frame (NDF) timecode, where every frame is counted sequentially. NDF is the right choice for web and most modern workflows.
