Frames to Timecode Calculator
Convert frame numbers to SMPTE timecode format (HH:MM:SS:FF). Essential for video editing, post-production, and frame-accurate synchronization.
Starting from frame 0
Common: 24, 25, 30, 60 fps
How to Use This Calculator
- Enter the frame number you want to convert (starting from frame 0).
- Enter your video\'s frame rate (common values: 24, 25, 30, 60 fps).
- Check "Drop Frame" if working with 29.97 or 59.94 fps NTSC video.
- The calculator displays the timecode in standard SMPTE format (HH:MM:SS:FF).
Timecode Formula
Timecode is calculated by converting total frames to hours, minutes, seconds, and remaining frames:
Hours = floor(Total Seconds ÷ 3600)
Minutes = floor((Total Seconds % 3600) ÷ 60)
Seconds = floor(Total Seconds % 60)
Frame = Frames % Frame Rate
Example: Frame 1250 at 24fps: 1250 ÷ 24 = 52.08 seconds. This equals 00:00:52:02 (52 seconds, 2 frames).
Full Description
SMPTE timecode is the industry standard for identifying individual frames in video content. It provides a universal way to reference specific moments in video, essential for professional editing, color grading, sound mixing, and multi-camera synchronization. Timecode ensures frame-accurate precision across all stages of post-production.
The format (HH:MM:SS:FF) represents hours, minutes, seconds, and frame number. This calculator converts raw frame numbers to timecode, which is crucial when working with frame-based editing systems or when you need to communicate specific frame positions to collaborators.
Drop frame timecode is a special variant used for NTSC video (29.97/59.94 fps) that compensates for the slight difference from whole-number frame rates. It periodically "drops" frame numbers to keep timecode synchronized with real-world time. Use this calculator to ensure accurate frame identification in your video projects.
Frequently Asked Questions
What is SMPTE timecode?
SMPTE timecode is a standard format (HH:MM:SS:FF) for identifying individual frames in video. It's used in professional video editing, broadcasting, and post-production for frame-accurate synchronization and editing.
What is drop frame timecode?
Drop frame timecode compensates for the slight difference between 29.97 fps (NTSC) and 30 fps. It drops certain frame numbers to keep timecode synchronized with real time. Use drop frame for 29.97 or 59.94 fps video.
How do I convert timecode back to frames?
Frames = (Hours × 3600 + Minutes × 60 + Seconds) × Frame Rate + Frame Number. For example, 01:02:03:12 at 24fps = (3600 + 120 + 3) × 24 + 12 = 8,940 frames.
Why is frame numbering important?
Frame-accurate editing requires precise frame identification. Timecode ensures editors, colorists, and sound engineers can reference the exact same frame across different systems and software, preventing sync issues.
