( -c:v is shorthand for -codec:v/ -codec:video).Ī very basic FFmpeg command looks like this: ffmpeg starts the command -i input_file.ext path and name of the input file -flag some_action tell FFmpeg to do something, by supplying a valid flag and action output_file.ext path and name of the output file.īecause this is the last part of the command, the filename you type here does not have a flag designating it as the output file.
Likewise, in the instruction -c:v prores, the flag -c:v tells FFmpeg that you want to encode the video stream, and prores specifies which codec is to be used. Flags are always prepended with a hyphen.įor example, in the instruction -i input_file.ext, the -i flag tells FFmpeg that you are supplying an input file, and input_file.ext states which file it is. Subsequently, each instruction that you supply to FFmpeg is actually a pair: a flag, which designates the type of action you want to carry out and then the specifics of that action. After you have installed FFmpeg (see instructions here), the program is invoked simply by typing ffmpeg at the command prompt.
