I try to explain myself... to do so I will use three images ...
I have two videos (video1.jpg and video2.jpg). I want to cut vertically each video and join the right side of video1 with the left side of video2 (video_final.jpg).
It is possible with kdenlive? another free application?
thank's!

Thank's Dalgo, but I need a little bit more help ;)
I played with different effects and Scale0tilt is what approached more, but I have a problem...
First I use Scale0tilt to 'cut' the right side of clip1 (1.png)
Second I 'cut' the left sido of clip2 (2.png)
When I join the two clips, I only see the left side of video clip1 (3.png)
Seems I need transparency for the cutted parts, correct? I tried with transparency effect, but no luck.
Can somebody guide me? Thank's!
