Whenever I try to play a clip (either from the project bin or from the tracks) the project monitor remains blank (gray). There is sound, the overlays work. I can even edit the video (blindly) but I can't seem to turn on motion picture in the project monitor. Probably related: For "extract frame", the save dialogue appears, but after hitting okay, nothing happens. No new file is created (not even a blank gray one). Reproducible: Always Steps to Reproduce: 1. Add video clip. 2. Play it. 3. No picture. Actual Results: No video is seen in the project monitor. Expected Results: There should be a video instead of the gray area. Previous versions worked fine.
Unfortunately, I cannot reproduce. Can you supply more details about where do you installed 16.08.0 from and which MLT version are you using? Do you have moveit disabled? On which distribution are you using Kdenlive? Thank you very much for your cooperation!
Created attachment 100666 [details] attachment-8598-0.html Hey, Thanks for the quick reply. I checked with settings and playback configuration and it seems like my build doesn't support GPU processing/movit library use. This will probably be the problem. I try to get around this. Thx.

On the contrary, movit/GPU support is only experimental and causes problems in some cases. So I wanted to make sure that you don't have GPU support enabled.

I have the same issue on my system. I cannot playback the project or a simple Clip. I allways have a gray screen.
Details of my system: Ubuntu 64bits 15.10. melt 6.3.0. kdenlive 16.08.0 (KDE Frameworks 5.15.0 Qt 5.4.2 (compilado con 5.4.2), El sistema de ventanas xcb).
What graphics card type, AMD, NoVidea, Intel, ...? Which OpenGL drivers, open source, proprietary, ...? What OpenGL information does Kdenlive report in the terminal window when started? I suspect some OpenGL driver issues, more so as you are using Ubuntu 15.10, where the later graphic card driver updates broke my AMD card, and Ubuntu 16.04 fixed these issues. Heard similar things for Nvidea.

Thank you in advance!!!!
I can confirm this bug. It does not work for specific setups, but I don't know why. The latest stable version of Kdenlive is 16.04.3. Quite big jump in the repository from that version to 16.08.0.. hmm stable? :-) Well looking forward to see what causes this. I would rather not be stuck in 16.04.. :-) But hey, calling a .0 version stable is pretty random too. :-) All the best. /G
The problem lies in the version of ubuntu 15.10. I upgrade my system and everything in kdenlive works fine.
