Oops, seems that their torsos got cut off in that once scene... maybe their top halves weren't supposed to be seen at all in that shot, and there was a bit of a technical error? Something that didn't quite go as planned...

I did not even notice that the cutoff was below the top edge of the screen!

TVs used to have overscan until recently, in fact many new TVs still do, so the cutoff on Astro would definitely be outside the screen. Not sure about the girl though, it seems pretty big...

But TVs were probably so low quality that you wouldn't notice.[/QUOTE]

I think that most of the overscan was in the horizontal direction, not the vertical, though I may be wrong on that. It looks like someone forgot to overlay a final layer of cels before shooting the frame. You'd think they would have spotted it when previewing the film (which they would have done on a projector rather than a cine-scope) unless the film went 'wet' from the lab to on the air due to production schedules

Yes, that is true; I suppose I should have included the image you provided, Tetsuwan Penguin, but I had already 97 images as it was.

F-Man: I studied TV repair way back in the last century, in the days of analog & CRTs, & I do not even recognize the term you use. I have forgotten so much.

Early TV's had rather poor horizontal sweep circuits which were linear only in the middle of the scan. So it was common practice to crank up the gain of the horizontal amplifiers to keep the non-linear edges of the sweep off to the sides of the screen. This also hid the retrace part of the cycle as well.
The vertical retrace interval had a lot of other stuff happening inside of it, like hidden messages and closed caption data. A good number of horizontal scan lines were thrown away during the vertical blanking interval, but the number of "active" lines were well known and were accounted for in the film to video transfer. I can't see the top and bottom of a frame being thrown away electronicly, and the dimension of 16mm movie file is pretty close to the 4/3 ratio of early TV.

BTW the reason for the 4/3 ratio of width to height for TV was that it was close to the academy dimensions, and also because that was how the early round CRT's were masked off, by leaving the sides round and squaring off the top and bottom.

Overscan did hide all four sides of the image. Black bars in movies are always smaller on CRT TVs than on a computer screen.
