Green stripes - no Matrox support ???

[Elie]

Don't forget to uninstall the old VT first, reboot then reinstall the latest.

It didn't help. I downloaded the new Videotools and the drivers. Then I uninstalled the Videotools and ran the Matrox uninstaller. After reboot I choosed standard VGA and then I installed the new drivers. After another reboot I installed the Videotools. So I think that I've done all right. But: I still have these green, flashing stripes.
PLEASE HEEEEEEELP !

Speed Pete,

To clarify the issue,

1. After installing the VideoTools, did you run the QuickConnect successfully (you got the test picture on your TV) ?

2. You are running PowerDesk version 5.41.008, and VideoTools version 1.52.033, right ?

3. Your DualHead Settings are at "DualHead disabled", or "Use DualHead DVD Max" (Not "Use DualHead Clone"), right ?

4. Your Desktop Colour Depth is set at 16bit and the resolution at 1024x768, or 1280x1024, right ?

5. In "PC-VCR Remote Properties/Advanced", you have checked "Output to video line out", right ?

6. When you play your Matrox MJPEG compressed files in PC-VCR, do you see the "green flashing stripes"

7. You are using files captured with the current combination of PD and VT, right ?

Pertti:
1. Yes. With quick connect all is fine and in this very little window were no stripes visible. But: using it the first time it crashed when hitting the save button
2. Yes. Exactly these versions.
3. Yes. That's correct. I tried Disabled and DVD Max.
4. Yes. I use 1280x1024 with 16Bit
5. Yes, I used this setting. Alternatively I can use AVI_IO with an similar setting.
6. Hmm... Yes and no: I can see the flashes already when I'm only looking at some inout signal but not capturing it. But if I capture it, the file is free of these stripes when looking at it ONLY on my computer monitor. Looking at it with TV activated in any way I have green stripes again.
7. I tried it with files of the new version and with files of sone older versions.

Speed Pete,

If you drop to 1024x768 what happens.

Elie

[Speed Pete]

I tried it, but it is the same as with 1280.

[Speed Pete]

Seems you have no further ideas?
So tell me please: am I the only one with this problem? If so, i would guess that my card is defective...

[Pertti]

What other programs or TSR:s you have running ?

Press "CTRL+ALT+DEL" to see some of them.

[Speed Pete]

In my "normal" win98 installation there are really many TSR's running. So I tried my clean, new installation I mentiond above, wich I had back-uped fortunately. There is only the Explorer, Systray, PDesk and PC-VCR (of course).

PS: Somewhere on a Matrox Webpage I found for VideoTools 1.51 this:
"known issues: Green flashes are sometimes visible on TV Output"
Do they mean the same flashes?

[Speed Pete]

It seems to me, some employees of Matrox read this forum. So I ask them: don't you know, whether this is a known problem.
I really could need some help!!!

[Gooshy]

Are you talking verrrry thin green lines? Maybe only a couple of pixels thick, that flicker and flash? Seem to always be flush to the right of the screen? I've got that on my MGA-200/RR-G/Vid-out add-on module, and nobody's ever been able to suggest a fix that worked.
E-mail on this would be most welcome.

Disable the output to tv, re-capture a new clip in our remote and play it back. Does this help? You don't need to enable the output to tv when playing back a mjpeg clip.

If it still happens, can you post a screen shot of a frame with the green lines or flashes?

If it still happens, at what data rate are you capturing at and what is your source?

Haig

[Speed Pete]

Gooshy: yes - my green stripes are looking exactly as you described. Perhaps you can help to solve this problem...

Haig: Once again: the stripes are NOT in the captured file! Of course I would be happy, if I could simply capture, without looking at it on the TV, but my captured files are of superb quality. But: I want to play some edited files out to my VCR, and so I have to activate DualHead or TV Out to do this. And then I see these stripes.
Desktop resolution is 1280x1024 at 16 Bit, but I tried some others too. The darker the movie is, the more stripes appear. I can influebce this, by reduce the settings to a verey dark image. My Data rate??? I use the best quality setting. But again: I see them too, when not capturing. The problem is independent of the source. But using S-VHS, which is not connected, I have the most stripes, because of this image is absolutely dark.
Because the stripes are not in the captured AVI it is not possible to make a screenshot.

Hi Speed Pete,

which cable do you use for capturing/playback to connect your source to your Marvel ?
Do you use a scart-cable which is connected to your VCR or TV ?

Did you try other cables ?

Bye, Uwe.

[Haig]

Explain this to me again. Why are you enabling any dualhead modes or TV Out when you output a mjpeg clip? Go into SH mode and output the clip to your vcr. Then playback this tape on your tv and see if you still get the lines.

The only green line issues we know of is if you have any DH mode enabled, you might get green flashes during the initialization of the video just before it plays. These flashes are only seen on the TV which is normal.
