Hey, I'm just new to Ubuntu 12.04 and Kdenlive. I love the program but I'm having an issue rendering title clips. If I just add a regular video it will render fine. But as soon as I add text (title clips) it fails to render. When I hit render, it instantly goes to 100 % and when I go to play the video, it says "the video has no playable streams." But if I remove the text from the video and hit render, it renders and plays properly. Is there a reason it should be doing this?
