It’s a busy Friday afternoon. Ten episodes need to be split into segments and exported. The last thing I want to do is keep calculating where the next segment starts. That repetitive arithmetic inspired 24+1.
What started with offsets and rounding grew into one calculator for everyday broadcast tasks: reformatting timecodes in bulk, checking durations, and adding, subtracting or summing time values.
01 / Reformat
Let’s speak the same timecode language.
Producers and editors don’t always speak the same timecode language. Reformat translates.
Paste a producer’s feedback list to extract the timecodes, leave out the comments, and copy the results in one go. Only need minutes and seconds? Switch from hh:mm:ss to mm:ss, and carry on with the conversation.
Batch input · Consistent output
02 / Round
Work out where the next segment starts.
Add 10 seconds to 00:19:58:00, then round up to the next five-second mark. Round applies the delivery offset and rounding rule to return 00:20:10:00—even across the minute boundary.
Less repetitive arithmetic. A little more time for coffee and a final check.
Flexible offsets · Rounding controls
03 / Duration
From in and out to a clear duration.
Check a segment’s duration from its in and out timecodes. Choose the frame rate and whether to include the end frame to match the task.
Frame-rate selection · End-frame control
04 / Calculate
Keep the timing. Skip the working out.
Programme timings often involve more than one sum. Add and subtract time values, or total a list of durations, then copy the result.

Teams & everyday use
24+1 is used by newsroom, TV production and multilingual social media teams for everyday timecode tasks. It’s free to use—no extra software cost.
