The key settings of the above for full CGA capture are: maxhwidth=768 # ensure max of 96 columns maxwheight=246 # ensure max of 30 rows linelength=912 # CGA standard linesperframe=262 # CGA standard haspect=2 # multiple of 2 vaspect=4 # multiple of 2 The multiples of 2 were chosen to eliminate color sampling (ie. 4:2:0) as a cause of chroma bleed. The image presents as centered in the 1600x1200 canvas, and was captured directly to UTVIDEO RGB, then cropped and post-processed afterwards.
