<div dir="ltr"><div class="gmail_default" style="font-family:georgia,serif">Hello dear freinds, <br><br></div><div class="gmail_default" style="font-family:georgia,serif">My problem is that i have 2 files :<br><br>The first one starts at 00.00.09.7617 and finishes at 15.45.17.252 and the seconde one starts at 15.45.01.2525 and finishes at 00.00.00.0025 (next day)<br>
<br></div><div class="gmail_default" style="font-family:georgia,serif">I would like to merge this to files, we can see that we have an overlap, so i cut the end of the first one to correspond to the begining of the first on but when i cut and i changed the header variable i saw that it was not changed.<br>
<br>These are the commands used to cut the first file<br></div><div class="gmail_default" style="font-family:georgia,serif"><br clear="all"></div><div class="gmail_default" style="font-family:georgia,serif;display:inline">

Please can you explain me why, because the problem is when i merged them sac added a sequence of 0 between the 2 files, and this is not normal because i cut the end of the first file to correspond to the begining of the seconde one.<br>
