The Professional's
Timecode Calculator
Timecode Calculator is more than just a simple SMPTE counter. It is a workflow utility designed
for
Video Editors, Assistant Editors (AEs), and DITs who need precision without opening their NLE.
Whether you are spotting for sound, calculating end credit durations, or converting frame rates,
this tool handles the math instantly.
🚀 Custom Frame Rates
Most calculators are locked to NTSC or PAL. We support the
entire spectrum.
- Standard: 23.976, 24, 25, 29.97 DF/NDF, 30.
- HFR: 50, 59.94, 60.
- Custom: Any integer or decimal.
📋 NLE Copy & Paste
Stop manually typing numbers. Detects formats from major
NLEs.
Simply copy timecode from Premiere, Resolve,
or Avid and paste it here.
➗ "End Credits" Divider
A finisher's
favorite. Find card durations instantly.
Enter duration (e.g., 00:00:45:00) ÷ cards (e.g.,
12) to get frames per card + remainder.
📜 Exportable Slate
Track your work. Every calculation is logged.
Review results and export as a
text file for editor reports.
Why use a dedicated SMPTE Calculator?
Video timecode relies on Base-60 math for seconds and
minutes, but switches to Base-24, Base-25, or Base-30 for frames. To make matters worse, Drop Frame (DF) timecode skips specific frame numbers to
compensate for broadcast standards.
Trying to calculate this mentally often leads to a "One Frame
Error," resulting in sync drift. This tool uses industry-standard algorithms to
ensure frame-accurate operations across all framerates.
