TPM: A Horizontal Line that's Not Supposed to be there (1 Viewer)

[Len Cheong]

I've noticed a horizontal line in the top of the screen. It is a black line that is just below the top border of the image. Has anybody noticed this? Do I have a defective disc. I've noticed it on my direct view and rptv.

Check the old Forrest Gump thread. I'm thinking that it's the same thing some people were noting on that release.

I haven't read the Forrest Gump thread, but it sounds like you might be seeing the visible artifact of the Analog Copy Guard Management System (CGMS/A), which places copy-protection information on NTSC lines 21 & 22. If you look closely for it, you'll probably see it on ALL of your DVDs. Seriously.
(I hope I didn't just ruin your entire collection for you!!)
Or maybe you're seeing something totally different, I dunno ... just a possibiliy.

I believe it's been identified as the same "ringing" or "edge enhancement" effect as on other areas of the transfer.
It is not on all DVDs.

In the beginning of the movie, when all you see is mostly black space and stars, I can see a fine horizontal line on the bottom and top of the image. Between the image and the beginning of the black bar, I would say it's about 2" thick on my 36FS13 Wega. Anyone know what this is?? This is the first DVD I have noticed this...
Thank You.

It could possibly be the real letterbox from the anamorphic image.
Uh...I mean, doesnt that TV have a 16:9 conversion mode? It works by moving the CRTs rasters so you see the full resolution from anamorphic dvds. The line you are seeing could possibly be the "real" black bars on the master of the dvd itself. Then, the darker ones above are the "negitive output" area of the CRT that isnt outputing any light.
I am not sure. I just know that those Wegas have that feature and Im justing guessing.

Yes, these are bruises from fighting. Yes, I am comfortable with that. I am enlightened.

2" inches thick? Sounds to me like you are seeing the Letterboxing mattes. This is normal on films with 2.35:1 aspect ratio.

Joshua, he says

I interpret this as meaning the line is 2" below the black letterbox bar, but not that the line is 2" thick.
I haven't looked for this on my TPM DVD, but the same thing is indeed showing up on my Forrest Gump disc. Since I still only have a crappy 20" TV, it doesn't bother me much (I wouldn't have noticed it on FG if I hadn't known about it), but I believe I read somewhere that it is due to the edge enhancement on the DVD. I have never seen Matt's explanation about copyright information before, but maybe that's what it is, both on this and Forrest Gump.
In any case, there's nothing you can do about it, AFAIK.

Hey guys,
Thanks for your analysis. I was just hoping it wasn't my TV.

Mine is just a horizontal black line. It is not thick at all. Just a thin line just below the top border of the anamorphic image. I'm exchanging my copy.

 

[Richard_Huntington]

They have that, Len. It's from excessive edge enhancement.

[Len Cheong]

But isn't edge enhancement represented by "halos" around objects? This thing is black line stretching across the screen.

 

[Patrick Sun]

If you have a Sony TV (flatscreen or tube), there's 2 tiny horizontal lines that appear at 1/3 and 2/3 of the screen height. My Sony PC monitor has the same 2 lines.

I was thinking that but the lines don't sound like they're in the right position. This is an artefact of all Sony Trinitron tubes. Very weird they can't get rid of it. Downside of quality, I guess.

 

[Len Cheong]

No, it's not the Sony lines. I've got a Toshiba tv and a Pioneer RPTV. I can't believe people haven't seen this line being that so many own this dvd.

 

[Scott Simonian]

Thats odd, my monitor that Im looking at right now is a Sony Trinitron. Pc monitor anyway and it has these two black lines at about 1/4 and 3/4 areas on the monitor. Allways thought it was a defect cause this thing is a few years old.
