Resolutions, Aspect Ratios, Frames Per Second

Resolution is how many Horizontal x Vertical dots/pixels you have on your display. I.e. 1920 x 1080. Aspect ratio is the horizontal width divided by the vertical height, i.e.: . Aspect Ratio tells you if the display is more square or more rectangle. The glitch video artist will encounter Resolutions and Aspect Ratios as they go in between different gear or programs. Some common formats are: Name Resolution Aspect Ratio Notes 35mm Film / DSLR camera Varies 3:2 Photography aspect ratio VGA (NTSC) 640x480 4:3 Early, popular computer monitor resolution. Composite (NTSC) 910x525 samples 4fsc (720x480 or & 720x488 active area) 4:3 Vertical resolution is variable, due to how analog televisions produce scanlines. Full HD 1920x1080 16:9 Widescreen 4k UHD 3840x2160 16:9 Widescreen Vertical Video Varies 9:16 The aspect ratio is reversed from widescreen, because the width and height are switched. Display resolution - Wikipedia Video Game Resolutions Interlaced vs Progressive scan modes In an interlaced signal, horizontal lines are drawn from left to right, in two passes. First the even numbered lines are drawn, and then on a second pass the odd numbered lines are drawn.On a progressive scan signal, lines will be drawn from top to bottom in one pass. Sometimes you will see resolutions written as 1080i29.97 or 720p59.97; to indicate if they are interlaced or progressive the numbers may be rounded for in-camera menus for example however.

From these frames of analog film, we have the measurement of Frames Per Second (FPS). 24 is considered the minimum for the Persistence of Vision effect. 30 FPS is a common minimum for smooth Persistence of Vision. Refresh rate (Hz) and Frames Per Second (FPS) are in the same scale, i.e. something per second. 60hz is 60 refreshes per second. 60 Frames Per Second is self-explanatory. FPS and Refresh Rate may have slightly different meanings in a video/broadcast context versus a video gaming context.
