I just got the SCART to BNC cable and I am having some picture issues. Also I am getting a real bad hmm/hiss from the audio
Check the monitor buttons, I'm thinking EXT Sync. Toggle it, it might be treating it as composite/component/s-video which are modes with "integrated sync". but that would give out a garbled image.
If it's not that I think it's
Line/RGB button.
Mess with that.
I've been wondering, if Framemeister is better at upscaling 480i signals compared to 480p, does that mean PS2 RGB looks better than PS2 component through the framemeister?
If that's so it depends on the game.
Well deinterlaced 480i can look almost as good as 480p if the game is 30 fps and the gameplay is slow/the camera is not free or very fluid... not regulable even... or if the scrolling speed... in case of 2D/2.5D content/gameplay is not very high... Something like an RPG or slow plataformer/sidescroller.
In this case, if the Framemeister gives a better still image out of it than it does with 480p it'll have the edge.
If on the other hand we're talking 60 fps 480p game, unstable framerate game, a game that horizontally scrolls very fast or has a very fluid regulable camera (say, like the one in Zelda WW using the second joystick) then unless 480p is hideous and badly scaled probably no way going 480i is preferable... it's kinda hard to explain, but 480i uses half frames or fields, so it either pulls 30 full frames out of 60 fields/incomplete ones (it works like this with DVD's and video in general) or... you'll have 60 incomplete frames, or some "single" half frames going on nonetheless - this is very normal, with frame drops and all. That's a deinterlacer worst nightmare because one can only acquire a complete frame out of two frames based on the same framebuffer reading, which is what the deinterlacer is trying to do every time.
Which is why if it is a very still game even if there's issues artifacts they won't be noticeable wether on a very fast game they just might.
Deinterlacing usually also adds up on the input lag time, precisely because it needs two half frames to process a result, those half frames have the same timing as two full frames in 480p.
If it's PS2 it'll be fine for most games over scart because most don't even support 480p. I'm using scart lately due to my scaler giving me geometry controls in RGBS but not over component and the PS2 games having such a ridiculous overscan going on.
