14:9 (1.5:1) is a compromise aspect ratio between 4:3 and 16:9.[1][2] It is used to create an acceptable picture on both 4:3 and 16:9 TV, conceived following audience tests conducted by the BBC. It has been used by most UK,[3] Irish, French, Spanish, Colombian and Australian terrestrial analogue networks, and in the US on Warner Bros. Discovery' HD simulcast channels with programming and advertising originally compiled in 4:3. Note that 14:9 is not a shooting format; 14:9 material is almost always derived from either a 16:9 or 4:3 shot.[1][2]
