video wall

I'm doing several versions of a few projects with each project having a 'video wall' preview for a few seconds. Other than building by hand a wall with a dozen or so thumbs of all the included clips a la video wall does anyone know if is there a filter or similar for doing same. Motion's 'video wall' replicator simply makes a lot of thumbs from one clip. I think I remember seeing it somewhere but can't put my finger on it.

CHV has the filter you need. Core Melt also has a video wall but you will need to have Noise Industries installed to purchase it.
