I'm working on a project with a separately recorded audio track and two video tracks; one from a Nikon D800 and another from a Panasonic Lumix DMC-TZ10. Thanks to the audio-based track alignment, getting it all to sync is now an easy process -- thanks to the developers for adding this feature!
I use proxying to speed up the editing process, but I have a problem when rendering to file from the originals (the same problem is also visible when disabling the proxy clips, btw):
When I clip INTO footage from the Panasonic (MTS AVCHD Lite format), kdenlive does NOT automatically go back to the previous I-frame to properly calculate the first frame to be used; it starts with a (gray) frame and uses only the B-frames that I clip into -- until it gets to the next I-frame. The same happens if I transition into a clip from the Panasonic. The result is pretty weird, as you might be able to guess...
I use a few color grading effect on the tracks (White Balance and Gamma -- needed for "color grading"), and only simple (dissolve) transitions.
There are no problems clipping into the D800 footage in the same way.
Am I doing something wrong? Or could this be an unfortunate bug?
I know I could just transcode to some other suitable format, but I'd rather not if possible, and just use proxies for the editing.
I have been doing something similar before with the same Panasonic, and didn't have problems then, as far as I remember, so any hints or ideas would be helpful.
Thanks in advance,
NB: For the record, I'm running Ubuntu Studio 13.04 using the latest stable versions from sunab's repo (0.9.6).
