Using the 'latest' CVS/SVN versions of ffmpeg, mlt and kdenlive, I am still having problems rendering NTSC (HDV) 1440x1080 video.
Using "HDV 1080 60i" the output is very 'jerky', and the rendered video appears to be running faster than the original, and the audio gets completely out of sync. Each transition renders as a blank (black) screen with no audio for the duration of the transition. Rendering to HD 1440x1080 has the correct aspect ratio, but rendering to DVD 16:9 results in a 4:3 aspect with black bars at top and bottom.
I tried setting the project to "HDV 1080 50i" and the transitions now worked OK, but the video was still very 'jerky'.
I have tried the same project file running only with inigo, and the overall results were the same..
As a comparison, I tried some NTSC DV (720x480) 16:9 video files, and the results were just as bad.
I then tried some old 4:3 PAL video samples, and the output and transitions seemed to be working OK...
