Sorry if this question has already been answered but I have a question about the Light Graffiti Effect. I have been using my Canon EOS 500D T1i DSLR for Light Graffiti photography and after hearing about Kdenlive, I'm getting ready to dabble in videos too. I was finally able to get Kden to respond with my computer and I love the program but I'm slowly learning. Thr problem I've ran into as of late is that when I preview the video in the project monitor and I apply the effect to the video, it keeps the effect OVER other videos if that makes sense. For example, if I have a video where I'm writing lyrics and I'm writing over them in the same areas or frames on the video, I apply the effect correctly but if I restart the video, the effects are still left over and they remain until I restart the program and apply the effect on the video again, and that works until I restart the video. So 1, is this a normal problem and I have to film and edit individual lyrics or parts, or 2, is this a problem in the program. Sorry for the long response and I hope it makes sense. Thanks in advance for the help.
