Cannot reproduce. Does this also happen with very simple projects (with only 2 or 3 clips ?). Can you make some tests to see if the problem occurs only when certain clips are in the project ? Maybe some of your hdv clips are corrupted and FFmpeg has problems seeking into them ?

In the timeline the video was correct displayed. Where can i search for the problem ?

Thank you very much

Can you reproduce the problem with a very simple project ( for exemple one clip cut in 2) ?

you could also try a very simple rendering with one clip that has this problem:

inigo clip.m2t in=10 out=100 clip.m2t in=200 out=300 clip.m2t in=500 out=600 -consumer avformat:test.m2t f=mpegts vcodec=mpeg2video s=1440x1080 b=19700k ab=384000 g=12 ildct=1 ilme=1 profile=hdv_1080_50i

To see if the problem still happens

Or you can try to render your project file to see if some error message is displayed:

inigo project.kdenlive -consumer avformat:test.m2t f=mpegts vcodec=mpeg2video s=1440x1080 b=19700k ab=384000 g=12 ildct=1 ilme=1 profile=hdv_1080_50i

Ok, i have rendered my project with you command and get the follwing error message at the end of the rendering process:

Segmentation fault 2814

this are not much information about the error. Is it possible to get more information about the rendering process ?

Thank you very much.

No, there is no easy way to get more info,but you can run it in gdb:

gdb inigo

run project.kdenlive -consumer avformat:test.m2t f=mpegts vcodec=mpeg2video s=1440x1080 b=19700k ab=384000 g=12 ildct=1 ilme=1 profile=hdv_1080_50i

Then, when it crashes you can type "thread apply all bt", press enter until full backtrace is printed than attach the backtrace here.

Please also make sure you have the latest MLT, a crash in rendering was fixed about one week ago.
