TimeCalc adds/subtracts SMPTE time codes, or hours/minutes/seconds. The calculator operates in 4 modes:
  • hours and minutes;
  • hours, minutes and seconds;
  • SMPTE frames; and
  • SMPTE frames and subframes.

SMPTE subframes are computed at 80 subframes to the frame. SMPTE frames rates can be any of 4:

  • 24 fps,
  • 25 fps,
  • 29.97 fps and
  • 30 fps.
When set at 29.97 fps, the calculator takes into account drop frames. Drop frame SMPTE timecode drops frame numbers 0 and 1 of the first second of every minute, and includes them when the number of minutes is divisible by more...

Very nice widget!

A suggestion:

- Make it so that you can re-edit the values (for instance if you want to change the seconds) after you have typed them in. As it is now, you are just pressing 1, then 12, then 15, if you want it to be 1hr 12min 15 sec. My suggestion would be that you should be able to click in the hours, minutes, seconds (and so on) fields and correct any mistake. If I'm not mistaken, there is no way you can correct typing errors. I might be mistaken, but anyway, I think this would be more convenient.

Maybe also (excuse me for being picky), make it a little bit tinier, slimmer. But that's just a cosmetic request.

Thanks for a great widget! I'm sure that many audio and video creators, like myself, will find this a very nifty tool.

Would be great if this widget could convert minutes to hours and minutes, as in "90 minutes = 1 hour 30 minutes." Seems I'm always converting DVD movie times. They're all given in minutes.
