Hi!

I am editing home video, captured with a Panasonic HDC-SD60 cam. It has worked well to edit in Kdenlive, but suddely I get one movie where the audio is off sync when rendering. It uses the project profile HD 1080i 25 fps. I have tried render the movie in mpeg2, mp4, xvid and vob format, and all produce audio that gradually goes out of sync. I tried do it with the MTS clips and I've tried first transcoding them to DNxHD. Audio out of sync each time

I tried render another film just to see if there was a problem with my system. This one also uses the MTS clips, but rendering it to mpeg2 works nicely - no sync problem.

Anyone got suggestions on how to work with this? What to check, what to try?

The system is ubuntu 11.04, everyting installed as regular ubuntu packages. Kdenlive 0.7.8.

Really no one got any idea on this? This problem totally destroys my current editing of video.

A few update:
SOME projects build on transcoded clips (MTS transcoded to DNxHD) works - rendering produces mpg2- and mpeg4-files in sync - but not all such projects.

NO projects built on MTS-clips produces synced films.

BUT: all mts-projects are rather new, and it seems that the older projects are the ones that work. So how can newer projects be more problematic?

I've tried different kernels - no change. DIfferent resoulutions - no change. mpeg, avi, vob - no change. All out of sync in the failing projects. But watching the film in kdenlive, before rendering, produces synced viewing.

What could I check, what to experiment with? What logs to examine, what settings to adjust?

Hi, if you're still checking the thread..

I also shoot with Panasonic's sd60, a nice camera. I shoot in one quality less than best, to fit more on the sd card.

I use kdenlive, but profile HD 1080p 50fps.

I render the MTS clips (copied to hdd straight from the SD card) to mpeg2 8000K.

I get good Q results, except for another problem, some of the clips I cut on the camera get frozen after the rendering/joining.
I posted here http://www.kdenlive.org/forum/mpeg2-rendered-mts-gets-freezes-some-joined-clips

But it also depends on how u installed ffmpeg, faac and the others. I'm on ubuntu 11.04 64bit, Core2.
