In my scene I have a text object I'm rendering over a photograph with nice natural depth of field. I am matching the depth of field effect with a defocus node in the compositor. Since the camera doesn't move for the duration of the sequence, I'd like to hold the first frame. Effectively rendering the defocus node for one frame and extending that frame in the VSE for the length of the sequence.
I do not want to render the frame out to a file and then import it back in. I will be doing this many time and want to avoid any manual two step process. I need a non-destructive way to do this in one step. In NUKE, this is a 'HoldFrame' node, in After Effect you can use TimeRempaing, FUSION also has a solution for this.
