Many thanks! It works

Right, now I have a wipe, but is it possible to freeze this wipe, eg. in the middle, so for 10 seconds I can have half of the video one the half of the screen, and the second video on another part of the screen, and after 10 seconds this wipe could finish?

Here is an example from kde (split screen):

I don't think you can do this with the wipe transition.

But maybe you could use two wipe transitions 10 seconds apart. Render that and import that into a new project. And then do a split screen bit of footage in the middle.
To do the split screen thing you could look at this tutorial on how to make side by side 3d footage and use the same technique described there - but minus the image shrinking that is done for the two video tracks
side by side 3D

Please correct me in case I misunderstood the original poster. As far as I understand wipes and I have used myself it should be possible to control and freeze the wipe effect. For this, do not apply the composite transition, throw in your wipe file and then set control points along your clip/transition for different Opacity settings. If you ramp up from 0% to 50%, then hold at 50%, then you should get what you want. The trick here is that for the Composite transition the Opacity controls the wipe.

I hope that I did not completely mess up here though.
