Welcome to the forum Video Collector.

How did you make those screen grabs out of interest? The reason I ask is that they appear to be half-height grabs scaled up using a simple point resize (which is why there is heavy aliasing on diagonal lines). I suspect that one of the fields - half the resolution - got discarded somehow when you made your screen grabs. This would mean that the actual tapes contain twice the vertical resolution of your screenshots!

Very much looking forward to seeing these.

The screengrabs were made from VideoReDo (just because I'm using that program for basic trimming of the "raw" captures ).

I'm using a consumer DVD/Harddisc recorder that captures realtime MPEG2 to harddisk. Not an ideal solution, granted (even at the highest quality setting there is some compression-related blocking).

The captures are at their native PAL DVD resolution 768x576. Dumped to memory, pasted into Photoshop at 72dpi and saved as jpegs. That being said, I have no idea how the framedump function in VideoReDo handles the interlacing. The aliasing may be an artefact of the harddisk capture/encoding, and maybe WYSIWYG.

All the same, these grabs should give a general idea of the image characteristics of the tapes. I don't want  anyone to get their hopes up too high.

Oh, and everyone, call me Fritz, okay?
