Silhouette for Review?

We are trying to implement new workflow in our roto department by submitting sfx file for review instead of rendering alpha images.

Is there any way to load the SFX file in Silhouette with limited functionality and faster loading time. So we can do the review with silhouette workfile.

It depends in what you mean by review. If it is not necessary to see the alpha channel and just see the spline over the image, the fastest method is to set the View menu to Foreground. That way, the alpha does not need to be rendered during playback.
