On the subject of telecine smearing, I actually don't know that much about telecine, I'm just calling what I see in old transfers.
Here are some examples of this pickup tube lag/decay issue, from one of the most egregious instances I've ever seen, the Warner Home Video release "Nelvanamation." These are individual fields, extracted using SeparateFields in Avisynth.
First, the old Saul Bass "worm" logo that WB was using at the time. Since it's red and white on black, it clearly illustrates what I'm talking about.
No, the text is not supposed to leave streaks like the credits to one of the old Christopher Reeve Superman films. Those are "ghosts" of the previous frames of film.
Notice that the closest "WARNER BROS" is not as opaque as the one right behind it. That's because the next frame is showing up "prematurely", at partial opacity. This is what I meant by two adjacent frames being picked up in the same field.
Now notice that only part of the next frame shows up, and at a different opacity than last time - you can see it sort of trail off about halfway up the "WARNER BROS".
Sounds like what SpacedRanger was talking about, though this transfer doesn't seem to have the exact issue he mentioned. I do remember seeing *some* old smeary transfer where when there was a cut to a new scene, you could see the top or bottom half of one scene show up "superimposed" over the other.
Now it looks like the two frames are picked up at almost the same opacity.
Again, the next frame seems to be most visible at the bottom of the screen.
Actually, I don't know what's going on - the "early bird" frame seems to be visible from top to bottom, but its opacity isn't regular. Look at the bottom left corner, where there's red in one frame and black in the other, and the red gets more translucent as you go up, but doesn't go away.
I don't even know if this can be called 3:2 pulldown at all. Each of these smeary images shows up in the bottom field of one frame, and the top field of the next.
I know this has nothing to do with PS78 itself. My point is this: Maybe the PS78 transfer has this kind of issue, and there are no "discrete" frames to speak of. If so, perhaps it'd just be best to blend the identical fields together to make it 30p?
I trust that Darth Mallwalker can figure out what to do after he sees the raw captures. (Actually, I'll look at that sample myself and see what I find when I break it up into fields.)
