  1. Hi ****
    please consider I have a mp4 file that have duration of 1 minute
    but I would like trim it so that is have to encoded from 0 to 0:00:31.040000

    can use time instead of frames?

    I'm in a 25fps timebase, thanks

  2. I assume that is H:M:S.ms notation ?

    You have to convert to frames. Obviously you cannot trim video on fraction of a frame

    1/25 = 0.04
    31 * 25 = 775
    775+1 = 776 frames

    Then script it with string parsing, saved to temporary memory values and then process & combine them. There are scores of excel code on the web for doing just this, and you should be able to port the ideas to a batch file, right?

    Well, then I wouldn't worry about it: cats have no need for timecode.
