PTDQ

WHAT IS THIS?

PTDQ (Pixel Tetrads Dots / Quality) is a video system for AGA Amigas that provides a chunky-to-planar method which is faster than the traditional ones.
PTDQ is the higher-quality brother of PTDS, another system based on the same core principle.

EXAMPLE

[The WinUAE capture is darker than it is supposed to be due flat gamma and contrast settings. The quality of the Amiga 1200 capture is heavily affected by the fact that the scandoubler did not support SHRES (so a real-time software trick was used to somehow produce the colors, although it is only a visual illusion and causes a sort of rasterline effect), the monitor did not support progressive PAL and the video was shot with an ancient phone at just 24.917 Hz. YouTube's compression degraded the video quality further.]
