I try Radeon7000 S-VHS out connect to Neptun Genlock .
The uBoot screen perfect work, but I do not know the same access to the settings in OS4 Picasso96.
uBoot well!
Almost good!
Want to know what framesize and pixelclock work uBoot?
Does anyone have information on this?
Thanx!

Obviously your screenmode does not have the same horizontal rate as the picture in the foreground. Very close, but slightly greater frequency.
Try changing the "Framesize (horiz)" from 832 to 840, see if that makes a difference. You can only change it in steps of eight IIRC.

I tried to set up and down, many setting!
I'm almost gave up when I noticed that the uBoot work without the problem.
That is, the cards can be set up, only Picasso96 dont know setup.

You have to match the settings of the two video sources so that they are the same in frequency and phase, both vertical and horizontal. Since I don't know what your two sources are, I can't help you except to offer suggestions.
The U-Boot screen is a VESA standard, 800x600. I don't know what scan rates it uses, I've never measured them. You will have to change the settings of the test screen shown so that it generates the same rates. I suggested one change, but you will have to experiment until you get it right.
Sadly, no one uses Genlocks these days. They went out of fashion with analogue televison a couple of decades ago.

We departures on interesting issue because I think beyond their own problem.
If we could find the problem source, many TV output would be useful.
