You mentioned a 768×768 NTSC signal? (approx) Since NTSC uses 525
scan/raster lines per frame (2 fields interlaced) How can we have more
than the number of horizontal scan lines? (Not even all of the 525 lines
are visible due to blanking/timing and/or other signals present in the
NTSC signal.) Is this correct?
