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?
Still, much easier to do pull that off when emulating a 405-line video tape with an even lower quality 16mm telerecording as your source. Getting an HD film transfer to look as good with automated interpolation is surely trickier?
Actually, a lot of the ones they were working on, particularly the latest two story finds, were full PAL 625 line video telecined at 25 fps to 16 mm film and scanned in full 1080 HD.
