this 8mm tape played by Sony CCD-TR728E with TBC on.

S-video "Inline Premium cable".

It makes me wonder why is there a green stripe on the right side of captured video. Same tape, but captured with Video8 camera (without TBC, Composite cable) no green stripes.

Crap cable or camera, please?

I recently also found a green stripe like that in the same position but the left edge on six Video 8 cassettes apparently recorded by the one Video 8 camera. I tested other unrelated tapes: good pictures, no green line. So in this case I guess it was on the recording.

According to other posts, it is a common issue on Sony hi8/Digital8 cameras. Even the VCRs capable play Video8/hi8

Camera. The sort of good news (from days of yore, is that it is in the nominal "over scan" area that would not have been visible on standard TV sets and CRTs. It becomes visible on the modern gear that often does not over scan. Same applies to the bottom and top edge stuff.

Yes, one losses extra 8-10Px on right side.

Over scan (amount) is defined by the display system, and was driven by the shape and variability of CRT displays and the mask around them. Broadcasters typically made an allowance for this by ensuring no important content of was in an assumed over scan area. typically 3% to 5% on each edge. Action Safe and Title Safe were terms often used to describe the areas for important content.

3% of a 720 pixel scan line is ~21 pixel from the ends of each. A similar percentage was hidden/masked from the picture height.

Modern TVs often allow setting the over scan amount.
