[Kdenlive-devel] Beginner: coverting avi to kdenlive format

Sat May 1 21:10:02 UTC 2004

Thanks.  From the website I see that I need either DV or AVI DV as the output 
file.  So that should mean the following would have been necessary, but it 
ends in a segmentaton fault.

[simon at new test]$ transcode -i in.avi -V -y dv -o out.dv
transcode v0.6.12 (C) 2001-2003 Thomas Oestreich, 2003-2004 T. Bitterberg

So I also had a go with mencoder:

But this file could was 7x bigger than the original and anyway did not seem 
playable by kdenlive.
So I'm still stuck... :-(
