I just tested AntiFlicker and DeFlicker plugins for Avisynth. Neither can properly handle a shot with anything moving in and/or out of frame (like the opening, scrolling titles). Even mostly static shots (like the long-shot of the boy walking toward SEN) continued to fluctuate. I would expect the commercial product DaVinci Resolve Lite to be "smarter", but I can't test it to discover how much better. If this problem was positional film-damage, then it wouldn't be cyclical for very long with ever decreasing circumference while unreeling. Fortunately, a semi-manual solution wouldn't be too burdensome.
Only these small sections will be included as "interesting extras" for this preservation. A short video presentation of the differences would be nice, something like this (rough mock-up):
and this:
If we have a better guess on when the "missing scene" disappeared, the above date will be corrected. Feel free to chime in.
Depending on extra disc space, the full-size 16mm clips would be included, sprocket holes and all.
