I have many old clips with low resolution, I'd like to make a "video-collage" with it (to imagine look here: http://www.fotos-hochladen.net/view/alle6o42s7erzn.png)
Is this possible with several tracks or do you have any other idea?

You will need a couple of tracks, each clip or track with a pan/scan/zoom effect (to get the correct position), and a composite transition between the tracks. You will find some help here in the forum if you search for "pip" or "composite" or in the manual.

works nice, thank you!

Hey, nice to get you sorted. Would you like to edit the topic and add a [solved]?
