The Doctor Who restoration team had a fantastic frame interpretation process. But if it is one frame, that would be easy enough to do in Photoshop. I looked and I didn’t see it. What is the GOUT frame number?
VidFire has some major limitations. If I recall correctly all of the Time Meddler, some shots from Tomb, and episode 5 of The Ambassadors of Death couldn’t be vidfire’d do to frame rate issues. Then again, 30mm isn’t a pal 16mm telerecording with NTSC color!
