Please help, I am having a hell of a time getting Kdenlive to output a non-choppy video on my very fast computer running Linux Mint 13 and Nvidia proprietary video drivers. Its a 6 core I7 extreme with 16GB RAM, but yet the preview screen in kdenlive and any output video is choppy... and maybe not so much choppy as it looks like it "surges". Even when viewed in VLC.
Viewing the source media is fine with no choppiness or surging. The source video are 720x480 vob files straight from a DVD. They do have an odd framerate though. I think it was 24.0635 frames per second. It complains about no matching profile when I bring in my two video clips.
Is it possible that the mismatch between profile framerate and source framerate is the cause? I've tried creating a new profile, but I can't create anything but whole number values when I try to create the profile.
I have verified the behaviour on a Mint 13 Core I7 laptop also. I get the exact same thing.
