--- Comment #10 from Aurelia <aurelia.gourb...@gmail.com> --- Hi Wegwerf, thank again for your answer. I will try to answer you as well as I can because I feel a little "lost" ;-) ! First: " First, to be sure, did you use the burn effect": I tried to use the "Burn" transition--->crash (with the error that I past) but the crash happen also with the other transition the same as my first post... Only a few of them function : dissolve, affine, diaporama... Second : "can you check if when the segmentation fault happens in line 65, is dst 0" How can I check this ? Third: "has b some sane value, within widt*height*4 I assume?" I can't find this item in the shell, where can I find this? Tell me more please ! I'm really want to find what's wrong.... Thank you very much again! This evening with my computer I try again , I past here the bug when I ran Kdenlive with gdb, this time with "overlay" transition: aurelia@aurelia-desktop:~$ gdb /usr/bin/kdenlive GNU gdb (Ubuntu 7.11.1-0ubuntu1~16.04) 7.11.1 Copyright (C) 2016 Free Software Foundation, Inc.
