My submission is about production effects, but the studio won give permission to submit a supporting video because the movie hasn been released yet. What should I do?
First, be certain that you will have permission to show the actual effects at the conference. If possible, submit a video that uses non-sensitive stand-in models or scenes to illustrate the techniques in question, with an explanation that the real thing will be shown at the conference. Contact the Sketches & Posters Chair to see if some special arrangement can be worked out. If all else fails, submit the abstract without a video, but with a supporting document listing in detail what the contents of the video will be, illustrated with still frames if possible.
