Hello,

since i upgraded my ubuntu studio from 14.04 to 14.10, i have a problem with rendering my videoclips to a correct working DVD-VOB file.
After rendering the clip with kdenlive (i use version 0.9.10) to a VOB and watching it in my software videoplayer, i noticed that the speed of the VOB-file changed to much faster.
i rendered the clips in MP4 and the speed of the videoclips was correct. but i would prefer a VOB file.

Any help would be very appreciated!

Thanks,
Pisco

Did you do "File Rendering" or "DVD rendering"? Two different options for "destination"
I have found DVD rendering produces file that are better for DVD authoring. I have seen the issue you describe and I believe I made sure I used DVD rendering to fix it.

thanks for your hint, ttguy!

i used the DVD option to render the clip.

it seems the problem is not a kdenlive specific problem. i tried the open shoot-application with the same result. the speed of the encoded file is to fast too.

maybe there is something wrong with the libav-tools package or a bug anywhere else in the system.

The fact that openshot also has this issue suggests it is a defect in the underliying melt/mlt/media loving toolkit upon which both kdenlive and openshot rely. Or it could be - as you suggest - in the libav code because they both rely on that too.

You can browse and report bugs in melt here http://sourceforge.net/p/mlt/bugs/

P.S. have you tried to render to mpeg2 from the File Rendering section to see if that works any better?

sadly i have the same problem with mpeg2 too.

i'm sure you are right that it depends on melt! i read that's the render engine, and converting a video-file with avconv in the terminal works fine. but i don't want to convert only!

hm, seems like no one else has the same problem. i didn't find anything in google.

probably there is no other solution to report the bug to melt and hoping they fix it.

thanks, ttguy!
