Cause of most of my noise is likely a sample error
I haven’t put much time lately into the amiga VSC but I put in a little tonight. I’ve got the image cleaner than it has been, but there is still noise on the left hand side, and a left-center band of...
Video artifacts present in scan doubled video
I uploaded a video to youtube that shows some video artifacts happening with the scan doubled video. The entire video shakes as if interlaced, but it’s not. Original res 320×200(15.7khz), doubled to...
