The ideal way to do this, would be to have your Rutt Ettra composition available as an image filter, which you could then apply to any clip playing in Resolume. Unfortunately, at the moment, we don't support QC compositions as effects (this will be something for R4). So out of the box there is no way to do this.
There are some workarounds in this thread
though, the easiest of which is to use Vade's movieplayer to load a clip inside the QC composition. Note that that could cause instability, so be sure to test thoroughly before going on stage with it.
