  1. Hello, I'm currently trying to find a frame perfect timecode syncing lineage. Although I'm confused on how to do it as I think I'm doing it the wrong way.

    Currently I open the first video in Avidemux and find a camera change and note the timecode. For this example let's do it with this timecode

    00:02:03.665

    And then I open up the second video and find the exact same frame which in this case is

    00:01:42.894

    What I usually do for each number is to convert the minutes and seconds in milliseconds and sum them up to a final number with the ms. In this case it was

    120 000 + 3000 + 665 = 123 665

    Same for the second number

    60 000 + 42 000 + 894 = 102 894

    Then I subtract both numbers

    123 665 - 102 894 = 20 771

    Then in mkvtoolnix I add this number as a delay, either a negative or positive value depending on which video track I want to sync it.

    It kind of work but since I just read about timecode and realised the number after the . isn't representing milliseconds but in fact a frame number.

    I'm confused as to why it's working and now I would like to know how to properly calculate these timecodes to get the real difference in milliseconds.

    Thanks for helping out!

  2. The number after (.) are milliseconds, not frame numbers.
    So 02:10:45.891 means 2 hours, 10 minutes, 45 seconds and 891 milliseconds.

    Any editor worthy of the name professional should have the option to show in multiple time scale options, and via frames would be the best way to calculate sync offsets, etc.

    So I was right

    Any recommendation?

  5. Premiere Pro can toggle display options


    A free way is avisynth , using showtime(), or showsmpte()

    http://avisynth.nl/index.php/ShowFrameNumber#ShowTime

    By convention the last "." indicates ms , but the ":" colon would indicate frames

    Thanks for the information about "." and ":", very appreciated!

    I'm already using Premiere Pro and AviSynth but I prefer Avidemux so far and ms are working great as well for syncing.
