Time-code Format

The Time-code format can be read as Frames or Milliseconds. What this means is, the fractional digits in the time-code (e.g. the last digits after the period) can represent frames of the video or milliseconds in time.
Frames 00:01:02.04
Read as: 0 hours, 1 minute, 2 seconds & 4 frames. 

It can also be read as total number of frames if the Frame Rate of the video is known.  let's say the frame rate of the video is 25 fps, we first identify how many milliseconds there are in a single frame and then divide the total number of milliseconds by that value.

Get the position in frames

  • We first need to normalize all of the values into milliseconds.
    • 1 minute equals 60,000 milliseconds (1 * 60 * 1000)
    • 2 seconds equals 2,000 milliseconds (2 * 1000)
    • 4 frames equals 160 milliseconds (4 * 40), remembering that 40 equals 1000 / 25 fps
  • Total milliseconds = 62,160 (60,000 + 2,000 + 160)
  • Milliseconds per frame = 40 (1000 / 25 fps)
  • Total frames = 1554 (Total milliseconds 62,160 divided by milliseconds per frame 40)
Milliseconds 00:01:02.160
Read as: 0 hours, 1 minute, 2 seconds & 160 milliseconds. 
This can also be read as total number of frames given the previous example when reading the time-code format in frames.
