No problem :-) I noticed this when I was editing and I had the HD video scaled down in a small window. Too bad it still doesn't satisfactorily explain the vertical vs. horizontal issue.
Well, if we try to make a breakdown of this.
In Star Wars, the original composite of the Leia hologram appear with thick horizontal lines in early letterbox transfers but not in any pan & scan transfer I've checked, clearly the issue of what you recently demonstrated. The composite have thin vertical scanlines that are hard to notice in the various low-res transfers.
In ESB; we have a similar thing with the hologram of the officers, where the pre-GOUT transfers displayed horizontal lines, but again, it should in fact just be vertical ones, oddly enough GOUT didn't create these "fake" horizontal lines this time.
The Emperor hologram seems to be the only one with thicker horizontal scanlines, they also appear on pan & scan video, '97 broadcast, Puggo's 16mm, 35mm references etc.
In Jedi, the hologram of Luke had very thick horizontal lines in GOUT but not in the '97 digital broadcast, must also be a case of what you just demonstrated. I'm just going on 005's comparison pics in this case.
The dotpattern on Vader's communication-screen, and the binocular shot in ESB just gave the illusion of having just horizontal lines in some early transfers, no mystery there. I think you just explained the issue or am I missing something?
The way I understand it, the only hologram with horizontal lines is the Emperor, all others have vertical ones. Except that Vader in the recent example of ours that seem to have very thin horizontals, but do they appear in the Blu-ray or film prints as well?
