I never thought I would face the problem with too fast renders, so congratulations on that.
The problem lies with heavy scene for cinematics. either in textures not loading fast enough, or lighting not updating fast enough.
I have changed all the lighting update speed etc.
What I think is needed (not a programmer only artist) is for the plugin to check that the scene is fully loaded before committing to the render. As at the moment it is capturing it while partiially worked out. Make it a check box in movie render queue, to force full scene load. I’m more than happy for slightly longer renders. at the moment I have spent 7 hours trying to fix it.
