| - | It is also, //time// being what it is, possibly to specify units less than a whole frame. The timecode ''00:00:12:12.5'' indicates 12 seconds, 12 frames, and a half of a frame. If you know how many frames are in one second, you can convert that value to milliseconds. For instance, if there are 24 frames per second, then 12.5 frames is ''.5208'' second or ''520.8'' milliseconds (because 12.5 divided by 24 frames is 0.5208, with 24 frames being a value equal to 1 second). | + | It is also (//time// being what it is) possible to specify units less than a whole frame.

| Timecode is available across both video and audio. Strictly speaking, you don't need to use SMPTE timecode if you are not working to video, but pragmatically it is probably available to you if you find it useful. Many DAWs display timecode just as happily as they display traditional hour-and-minutes counters or measures-and-beats. | Timecode is available across both video and audio.
