How to make side by side videos in Virb Edit or PIP

Does virb edit allow you to make side by side movies? I would like to compare i.e. 1080/60 vs 4k/30 fps on one screen but it seems I can not do it, also how can I make picture in picture films (I am using the virb camera and another old camera which exports to AVI but the files are not recognized by virb during import - Virb simply doesnt see them).
