uid attempts to recognize the existing pixel format automatically.
If the import operation results in unwanted distortions/aspect ratios, you can define the correct
pixel format here. CCIR PAL/NTSC refer to the 4:3 aspect ratio.
PAL format can vary (768x576 or 720x576) depending on pixel shape. Most graphics programs generate
square pixels. Positioned side by side, 768 of them make up the full width of the video format. For televi-
sion images, only 720 pixels are necessary since the pixels are somewhat wider than they are high (i.e.
rectangular). As a result, 768 square pixels = 720 PAL pixels. This means a picture with 768x576 pixels
created with a graphics program completely fills out the PAL television format (assuming the pixels are
square). The values for NTSC are: CCIR NTSC = 720x486; NTSC (square pixels) = 640x486.
