Hi everybody I know that i can use -pix_fmt for desire pixel format in output. When i list the different switches for this parameter i can see many formats such as yuv420p and yuvj420p. First i would be pleased if somebody explain whats the difference between these two format? secondly how can i change the bit depth from 8 (which is default in these two format) to something else like 3 or 4? Regards Amir
