I installed 0.7 today from deb http://ppa.launchpad.net/baudm/ubuntu intrepid main.
I hope to be able to merge about 70 small video AVI clips (MPEG-4 part2 from a Flip video camera) after editing some of them.
My idea is first to do the edits of about 20 clips outputting each of them back to AVI files and then to merge all avis by adding them to the kdenlive timeline workarea (is this a sensible approach?).
I tried a dummy edit on one avi clip file and selected Render then DVD.
When trying the rendered output on Totem player, Mplayer and VLC there was only sound, no video. Also the generated output was small, ca 1.5MB compared to the input avi file that was 29MB.
I also tried rendering DV PAL and DV PAL 50. There was video output but it came out as a narrow band at the centre of the screen, squashed vertically.
I am a total videoedit newbie experimenting trying to learn kdenlive and need advice.

Updated to kdenlive 0.7.1 today via Synaptic manager and video is now present in .avi, .mpeg2, .mp4 and .vob files.
