Multiple video's at the same time ?

Hi Reaper Video Guru's (Jon: hope you are reading this!), Situation: I received multiple video files from a client. These files were made by several people, singing along with one and the same verse from a commercial track.(so the files contain video AND audio). Now i bring these videofiles into Reaper, each on their own Track. I "lip sync" them. Now, i want to have shown all these video files at the same time, each video taking up a part of the video screen. Is this somehow possible in Reaper ?

I can't help, but .. This have a name: PIP or picture in picture Try to search or google: pip picture in picture reaper daw

Just throw the pan/crop preset on each and you can do it unless I'm forgetting something. I can't remember if I did this in Reaper or Davinici but it's the same process in both... resize and position:

Make sure you make the background transparent. I just used the Zoom pan preset. (Clear bg)

If you leave the BG black you get borders for free. Maybe that's different in Reaper. :)

all that has been said above is correct. there's also a 2x2 preset that will do it automatically like Karbo's example.
