UV Maps

Wed Jul 17, 2013 4:09 pm
Hi I've been looking at transitions but can find no examples of how to use UV map anywhere.

I understand that it's typically used in 3D but that doesn't mean that it can't be used to distort 2d any which way you like and indeed that distortion be animated (so a video that's a UV map). I've used UV mapping on 2D writing demos in assembler on a 286/386, so I'm familar with the concept for 2D graphics.

The kind of effect I wantes to produce was dropping text possibly with some additional morphing or other types of morphing.

This effect isn't avaiable but it should be perfectly possible to do it with a UV map, some uv maps (like making the video turn into say 2 pixel line segments scrolling up and down the screen getting progressivly longer and faster) should be a kind of stock UV map that can be used with lots of things. (But I can't find anything like that on the internet)

So anyhow, how do I create a UV map that can be used with KDEN Lives Transition feature (format and preferbly some software suggestions, though I'm not beyond writing a bit of C code to create some)? And can I create an animated one.

If you want to create a new transition you would need to use the MLT frame work. Kdenlive just calls MLT functionality. You would write a new Frei0r filter to do the job. See http://www.mltframework.org/bin/view/ML ... r-addition for example.
